Introduction to Personal Finance

The Big Questions

1. What is personal finance and why is it important for individuals?
2. What are the pillars of personal finance?
3. What are some common savings and investment options?
4. How can you protect your savings and assets?
5. What is income tax?

Have you ever received pocket money or money from relatives during festivals or special occasions? Think about how you usually use that money.

• Do you spend it immediately or save some of it?
• Do you keep your savings in a piggy bank (gullak) or somewhere else?
• How do you manage expenses, such as travelling to school, buying stationery, or occasionally purchasing food from the school canteen?
• Have you ever planned your spending to save for something you wanted later, like visiting your grandparents during summer break?

Our journey into managing money begins in childhood. As we grow into adulthood, we earn income and spend it in many ways to fulfil our needs and wants. We also save money and make investments to achieve goals, such as buying a house or funding higher education.

Individuals and households in today’s world have to make many decisions involving money. Money is, therefore, an important resource that should be utilised efficiently. This is where an understanding of personal finance becomes important. Personal finance refers to the planning and management of an individual’s money to meet their needs and wants. It involves making smart financial decisions, such as how much to spend, how much to save, where to invest, and how to prepare for future financial needs. For instance, if someone wants to buy a house in the next five years, they will have to plan and manage their money well to achieve this goal.

Pillars of Personal Finance

Income (Earnings)

Income is the money a person receives regularly or occasionally in return for products sold or services rendered. It is the starting point of personal finance because, without income, it is not possible to spend, save, or invest. For example:

• A teacher earns a monthly salary.
• A shopkeeper earns profits from a business.
• A person earns rent from letting out property.
• An investor earns interest from bank deposits.
• A shareholder receives dividends and interest from securities.

THINK ABOUT IT

• Have you ever thought about earning your own money? What kind of skill would you require, and which work would you choose?
• There are many ‘Earn While You Learn’ programmes that allow college students to continue their education while earning an income through part-time work, internships, or apprenticeships. This not only provides financial support but also helps them gain practical skills, work experience, and a better understanding of the real-world workplace.

Budgeting (Planning Expenses)

Budgeting means planning in advance how income will be spent. A budget is a written plan that aims to balance income and expenses. People often plan to save and make financial decisions with a specific purpose in mind to be achieved in the future. For example, a family may decide how much money to save each month or spend monthly on food, rent, school fees, transport, etc. Other examples include:

• Saving for a school trip next month.
• Buying sports equipment after six months.
• Saving for higher education in the future.
• Setting aside money for emergencies.

Setting such financial goals helps people prioritise their needs and make careful decisions regarding spending, saving, and investing. One simple way to set goals is to ask:

• What do I want to achieve?
• How much money will I need?
• By when do I want to achieve it?
• What steps can help me reach this goal?

Budgeting helps control unnecessary spending, such as excessive eating out or impulse shopping, and enables people to prioritise important expenses. It also helps people live within their means by balancing income and expenditure.

THINK ABOUT IT

Suppose you and your friends need to buy new badminton rackets for an upcoming tournament because the old ones have worn out. How would you manage your budget to cover the cost? Would you cut back on other expenses, use your savings, or borrow the amount from your parents or friends?

LET’S EXPLORE

Think of all your expenses and prepare your monthly/weekly budget using the template below

Steps in Budgeting

1. Identify your expenses: Begin by listing all your monthly expenses, both large and small. This helps you understand where your money is being spent.
2. Set a savings goal: Decide how much you want to save, what you are saving for, and by when you need to have it saved up. A clear goal makes saving easier. For example, to save ₹3,000 in six months for a new bicycle, you would need to save ₹500 each month.
3. Track your spending: Regularly compare your actual spending with your budget. This helps you identify areas where you may be overspending and make corrections if needed.
4. Review and adjust your budget: A budget should be reviewed periodically to reflect changes in income, expenses, or financial goals. For example, rising transport costs or unexpected medical expenses may require adjustments to the budget. Regular reviews keep the budget realistic and effective.

Saving

Saving means keeping aside a part of one’s income for future use and represents a financial surplus accumulated over time. Savings are important for comfortable living and because life is uncertain and emergencies can arise at any time. People also save to make future investments in assets, such as fixed deposits, stocks, mutual funds, and real estate.

THINK ABOUT IT

• What would you do if you received ₹100 today? Would you save some or all of it, or spend it right away?
• In the Grade 9 Part 1 chapter ‘Building Blocks in Economics: The Problem of Choice’, you learnt about wants and needs. Would you prefer spending the money on a want or a need?
• Financial experts often suggest saving first and spending what is left. Do you agree?
• Do you think individuals with low income can also save? Why or why not?

Investing (Growing Wealth)

Priya and Sameer both receive ₹500 as a birthday gift. Priya keeps her ₹500 in a piggy bank at home. One year later, she still has ₹500. Sameer puts his ₹500 into a savings scheme that earns 8% interest a year. One year later, he has ₹540. Both are being responsible with money, but are they doing the same thing?

Investing means putting your savings into assets with the aim of protecting their value and generating returns. It is like planting a mango tree—you do not get fruit immediately, but once you do, it continues to provide fruit for many years. While keeping savings in cash provides greater liquidity, investing helps increase wealth and protects the value of money. It also allows money to grow faster than the rate of inflation. For example, if a school bag costs ₹1,000 today, and inflation is 6% per year, the same bag may cost about ₹1,060 next year. If your money is simply kept at home and does not grow, you may not be able to buy the bag as your purchasing power will fall over time.

Do you remember the story of the king and the sage from the Grade 7 chapter ‘Banks and the Magic of Finance’? It explained the principle of compounding, where returns are earned not only on the original investment (the principal) but also on the returns already earned, thereby accumulating high returns over time. Let us understand this again with an example.

Liquidity: Refers to how quickly and easily an asset can be converted into cash or a cash equivalent without affecting its value.

Inflation: The increase in the prices of goods and services over time, which reduces the purchasing power of money. As prices rise, the same amount of money can buy fewer goods and services than before.

Purchasing power: The real-world value of money, measured by the quantity of goods and services a single unit of currency can buy. It determines your standard of living, as higher purchasing power means you get more goods and services with the same amount of money, while a decrease means you can afford less with the same amount of cash.

Compounding: The process where an investment’s earnings, such as interest or dividends, are reinvested to generate their own additional earnings over time.

Power of Early Investments

Suppose two people, Bhavisha and Dhruv, each save ₹1,000 at the end of every year and earn 7% annual interest. The only difference is that Bhavisha starts saving at the age of 25, while Dhruv begins at the age of 35. Although both save the same amount each year, since Dhruv invested much later, by the age of 65, he accumulates only about 40% as much money as Bhavisha. This happens because compounding allows earlier investments to earn returns for a longer period, and those returns continue to generate additional returns over time.

LET’S EXPLORE

• In Fig. 5.4 above, the curves are flatter in the beginning and tend to become steeper in the later years. Why do you think that happens?
• Talk to your parents and find out the fixed deposit rates of their bank. You can also refer to the bank’s website.

Common Investment Options

But where can one invest? Let us explore some common investment options.

    

Fixed Deposits (FDs)

Fixed deposits are among the most common and safest investment options offered by banks and post offices. In a fixed deposit, a person deposits a lump sum amount for a fixed period, such as one, three, or five years. During this period, the bank or post office pays a fixed rate of interest on this amount, which remains unchanged throughout the investment period. Fixed deposits offer assured returns and are suitable for people who prefer safety over high returns.

Other government-backed investment options include the Public Provident Fund (PPF) and small savings schemes, such as the National Savings Certificate (NSC) and the Sukanya Samriddhi Yojana. These schemes encourage long-term savings while providing safe and reasonable returns.

Maturity period: The duration between its issue date and the point at which the issuer repays the principal amount.

Bonds

Bonds are investments through which people lend money to the government or companies (issuers of bonds) for a fixed period. Bondholders earn regular interest. For example, if you buy a bond worth ₹10,000 that pays 5% interest per year, you will receive ₹500 as interest after one year. If the bond matures after one year, you will receive ₹10,500 in total. In reality, the maturity period ranges from 1 day to 30 years or more. You may also be able to sell the bond before maturity if you need the money earlier, making bonds more liquid. Government bonds are generally considered safer than corporate bonds and are suitable for those seeking a stable, predictable income.

Corporate bonds: Debt securities issued by companies to raise capital from investors. When you buy a corporate bond, you lend money to the company. In return, the company promises regular interest payments and to repay the initial principal amount when the bond matures.

Stocks (Equity or Shares)

Shares represent ownership in a company. When a person buys shares, they become a part-owner of that company and may earn returns through dividends as well as an increase in the share price. Investing in shares involves higher risk because share prices fluctuate due to market conditions, company performance, and broader economic changes. However, shares also have the potential to generate higher returns over the long term. They are, therefore, suitable for investors who are willing to take greater risks for higher returns and who invest keeping the long term in mind.

BSE SENSEX: The BSE SENSEX (Stock Exchange Sensitive Index) is the benchmark index of the Bombay Stock Exchange (BSE). It tracks the performance of 30 large, financially sound, and actively traded companies from different sectors of the economy and serves as an important indicator of the overall performance of the Indian stock market.

LET’S ANALYSE

Look at the graph below that displays the performance of BSE SENSEX over the years. It fluctuates over short time periods; however, it can go up significantly in the long run. Why do you think these fluctuations happen? Discuss possible reasons with your classmates and find out more from newspapers, the internet, or by speaking to your family members.

Mutual Funds

Mutual funds pool money from many investors and invest it in a basket of shares, bonds, or other financial assets. These investments are managed by professional fund managers who decide where to invest the money. If the investments perform well, investors earn returns in proportion to the amount they have invested. However, if the investments perform poorly, investors may incur losses.

Mutual funds are popular because they reduce risk by spreading investments across different types of assets, a strategy known as portfolio diversification. They are suitable for people who may not have the time, knowledge, or experience to manage investments on their own.

THINK ABOUT IT

Have you heard this disclaimer in mutual fund advertisements on the television?

“Mutual fund investments are subject to market risks. Please read all scheme-related documents carefully before investing.”

Why do you think this is included?

Protection and Risk Management

Life is full of uncertainties, such as illness, accidents, loss of income, or damage to property. These unexpected events can lead to significant financial losses. Therefore, an important aspect of personal finance is protection—safeguarding your income, savings, and assets against such risks.

Insurance

One of the most effective ways to achieve financial protection is through insurance. Insurance is a legal contract in which an individual pays a regular amount, called a premium, to an insurance company. In return, the company agrees to provide financial compensation for specific losses or expenses covered under the policy. For example, a family may pay ₹500 every month for health insurance. If a family member requires medical treatment, the insurance company covers a large part of the hospital expenses. Without insurance, the family might have to use a substantial portion of its savings for the expenses incurred towards the treatment.

Insurance works on the principle of risk sharing. Many people pay premiums into a common pool. In case of any unexpected loss, those insured receive financial support from the insurance company. Therefore, insurance provides financial security during emergencies, reduces the impact of accidents, illness, or property damage, helps families recover from financial setbacks, and encourages people to save and plan their finances through regular premium payments.

Types of Insurance

1. Health Insurance

   Health insurance helps cover medical expenses, such as hospitalisation, medicines, diagnostic tests, and treatments. It reduces the financial burden of illness or accidents and allows families to focus on recovery rather than worrying about medical costs. In India, government schemes such as Ayushman Bharat Pradhan Mantri Jan Arogya Yojana provide health insurance coverage to eligible low-income households.

2. Life Insurance

   Life insurance provides financial support to a family if the policyholder, who may be the breadwinner of the family, passes away. It helps dependents meet daily expenses, continue children’s education, and repay loans. Life insurance is an important tool for ensuring long-term financial security.

3. General Insurance

   General insurance protects against losses related to vehicles, homes, businesses, and other property. For example:

   • Motor insurance covers repair costs and damages caused by vehicle accidents.
   • Property insurance protects homes and businesses against losses caused by fire, theft, flood, earthquake, and other disasters.
   • Crop insurance protects farmers from financial losses as it covers damages caused by natural disasters, pests, and market price changes.
   • Cattle insurance protects farmers and dairy owners against financial loss in case of death or disability of their animals.

Borrowing and Credit

Sometimes, people may need to borrow money from banks, relatives, or other sources as loans. Borrowing or using credit can be helpful when it is used for productive purposes, but it can become harmful if misused. For instance, an education loan can help a student pursue higher education, whereas borrowing money to purchase unnecessary consumer goods may lead to a debt burden and financial difficulties. Thus, responsible borrowing involves taking loans only when necessary and ensuring that they can be repaid on time.

Debt: Amount of money owed to somebody.

THINK ABOUT IT

Have you ever heard your parents say, “This month’s EMI has been paid”?

An EMI (equated monthly instalment) is the fixed amount of money a person pays every month to repay a loan.

Suppose a family buys a refrigerator costing ₹30,000 but does not want to pay the entire amount at once. In such a case, they may take a loan and repay it through an EMI of ₹3,000 every month for 12 months. Each EMI includes a portion of the original loan amount (the principal) as well as the interest charged by the lender. EMIs are commonly used to purchase mobile phones, household appliances, two-wheelers, homes, and cars.

• Why might a family choose to buy something on EMI even if it costs more in the long run?
• Can having too many EMIs affect savings and emergency funds?

Risk and Return

When deciding where to invest money, it is important to consider four factors—risk, return, time horizon, and liquidity.

Risk: Refers to the chance of losing money.

Return: The profit earned from an investment.

Time horizon: The length of time for which money can remain invested.

Liquidity: How easily an asset can be converted into cash when needed.

Different investment options have different levels of these factors. For example, fixed deposits (FDs) are generally low-risk options that provide steady but relatively lower returns. Mutual funds may offer higher returns, while shares (equity) have the potential to generate the highest returns over the long term but also involve the highest level of risk.

In general, lower-risk investments tend to offer lower returns, while higher-risk investments may offer higher returns. Therefore, people should choose investments based on their financial goals, the amount of risk they are willing to take, and when they are likely to need the money.

Taxes

Taxes are compulsory payments made by individuals and businesses to the government to fund public services, such as schools, hospitals, transport, defence, and other essential facilities. There are two main types of taxes:

• Direct taxes, which are paid directly on a person’s or organisation’s income or profits, such as income tax.
• Indirect taxes, which are added to the price of goods and services, such as the Goods and Services Tax (GST).

Personal Income Tax

Personal income tax is a tax paid on the income a person earns in a year (called a financial year, say 1 April 2001 to 31 March 2002). All citizens of India with a personal income are required to pay income tax, with the sole exception of individuals who earn below a certain limit and are exempt from paying the tax. As income increases, the tax payable to the government also increases. This system is known as progressive taxation, which aims to reduce income inequality by imposing higher tax rates on individuals with higher incomes.

The underlying principle is that people with greater financial capacity can afford to contribute a larger share of their earnings towards funding public services, such as schools, hospitals, roads, and security. Paying taxes honestly and on time is an important responsibility of every citizen, as it contributes to the well-being of society and the development of the country.

India follows a slab system for calculating income tax, as shown in Table 5.1. Under this system, taxable income is divided into different ranges, called tax slabs, and each slab is taxed at a specified rate, as seen in Table 5.1. The tax slabs are proposed by the Ministry of Finance as part of the Union Budget presented to Parliament every year. The Central Board of Direct Taxes (CBDT), under the Ministry of Finance, is responsible for administering the laws relating to direct taxes in India.

Let us understand how a person’s income tax liability is calculated. Suppose Priya, a business analyst, earns ₹14 lakh per year. Firstly, her income to be taxed will be calculated as follows:

Step 1: Calculate Taxable Income

Particulars	Amount (₹)
Annual Salary	14,00,000
Standard Deduction	75,000
Taxable Income	13,25,000

Standard deduction: A fixed amount that salaried employees and pensioners can deduct from their income before calculating income tax, as allowed under the Income-tax Act, 2025.

Step 2: Apply the Tax Rate as per the Tax Slabs

Different portions of income are taxed at different rates. For Priya, the first ₹4 lakh of her income are not taxed; the next ₹4 lakh are taxed at 5%; the next ₹4 lakh are taxed at 10%, and so on, as seen in Table 5.2.

LET’S ANALYSE

• Sai’s taxable income is ₹3,80,000 in a financial year. How much income tax does he have to pay according to the above tax slabs?
• Ask your parents, a relative, or a person in your neighbourhood if they file personal income tax returns. Make a small report on the procedure to file an income tax return. You may refer to the following website: https://www.incometax.gov.in/iec/foportal/help/all-topics/e-filing-services/file-income-tax-return.

In conclusion, managing money wisely is not just about earning more—it is about making careful financial decisions at every stage, whether it involves spending, saving, investing, protecting against risks, borrowing responsibly, or paying taxes. The choices individuals make today shape their financial future and determine their ability to achieve financial stability while managing financial opportunities and challenges.

Before We Move On

• Making informed financial decisions from a young age builds financial security, independence, and confidence for the future.
• Personal finance rests on the five pillars—income, budgeting, saving, investing, and protection—to ensure financial security for individuals.
• Budgeting helps individuals plan their expenses, control unnecessary spending, and save for future needs. Saving and investing are important for building wealth, meeting goals, and protecting money from the effects of inflation.
• Different investment options involve different levels of risk and return, so investment choices should match an individual’s goals and risk tolerance.
• Insurance protects individuals and families from financial losses during contingencies.
• Income tax helps governments provide essential public services and infrastructure. Paying taxes honestly is a citizen’s responsibility and helps the government provide public services and promote national development.

Questions and Activities: Managing Your Personal Finances

1. Why is managing money wisely important for all individuals irrespective of their income?
2. How can budgeting help people balance their present needs with their future financial goals? Give examples.

School Reopening Budget Activity

3. School Reopening Budget Activity

Your parents have given you ₹3,000 to prepare for the new school year. Make a list of the items you need, find out their prices (by visiting local stores or asking a parent or teacher), and prepare a budget. Calculate the total cost and check whether it stays within ₹3,000.

• If your total is less than ₹3,000, you may add one additional item of your choice.
• If your total exceeds ₹3,000, decide which item(s) you can postpone or avoid buying to stay within your budget.

Use the budget template provided and ensure that all expenses are accurately calculated.

4. Why is saving alone often not enough to build wealth in the long run? How do investments help increase the value of money over time?

Investment Planning Activity

5. Investment Planning Activity

Suppose you received cash gifts worth ₹3,000 on your last birthday and decided to save ₹1,500. With the help of your teacher, calculate the returns you might have earned if you had invested this amount in different combinations of investments.

For example, what returns would you have received if you had invested ₹500 in a fixed deposit, ₹800 in the stock market, and ₹200 in gold? Try other combinations and find information on the returns from different investment options using reliable sources, such as newspapers, magazines, or official websites. Based on your findings, prepare an investment plan explaining why you think each investment option is suitable or unsuitable.

6. How does inflation affect the value of money over time? Why should people consider inflation while making financial decisions?
7. Different investment options involve different levels of risk and return. Do you think taking higher risks is always the best way to earn higher returns? How should a person decide which investment option is most suitable for them?
8. Why do people buy insurance policies even though they may never face a major loss? How does insurance provide financial security?
9. Imagine your family receives ₹1,00,000 from farming, a small business, livestock sales, and savings. Help your family decide how to use the money wisely.

Family Budget and Savings Activity

Step 1: Prepare a Budget

Allocate the ₹1,00,000 among the following categories:

Step 2: Needs vs Wants

Classify each expense as a need or a want and give a reason. Examples:

• School fees
• New mobile phone
• Better seeds or livestock feed
• Festival celebrations
• Water storage tank

Step 3: Save for the Future

Suppose your family saves ₹30,000 at 8% compound interest per year.

Using the formula A = P(1 + r)ⁿ, where A: Amount, P: Principal, r: Rate of compound interest, n: Number of years, calculate:

1. The amount after 5 years.
2. The interest earned.

Step 4: Save First, Spend Later

Many financial experts recommend:

Expenses = Income – Savings

If your family receives ₹1,00,000 and saves ₹20,000 first, only ₹80,000 is available for spending. This helps ensure that future needs and emergencies can be met.

Step 5: Reflect

1. What percentage of the money did you save?
2. Which expenses were needs and which were wants?
3. How can savings improve a family’s financial security?
4. How does compound interest help money grow?

Challenge: Create a pie chart showing how the ₹1,00,000 was allocated across different categories.

Introduction

What happens if the mangoes your parents bought last week are now half the price? Why are vegetables expensive in the morning but cheaper in the evening? Or why does the price of onions seem to change every few months? Why does the same flight seat cost ₹3,000 on one day but ₹9,000 on another day? Why do shops and malls announce discounts at certain times of the year? Have you ever wondered about the reasons behind these situations in a market?

In the Grade 7 chapter ‘Understanding Markets’, you learnt about the interaction among buyers and sellers and how prices adjust when sellers set them too high or too low. Prices do not change randomly; they react to what people want, how much is available, the seasons, festivals, trends, and sometimes even rumours. Whether it is snacks, movie tickets, mobile phones, or vegetables, the prices of all goods and services are determined by two powerful forces constantly at work, that is, demand and supply.

This chapter explores the concepts of demand, supply, and price determination and provides a glimpse of the outcomes of their interplay in real-world situations.

Demand

As the mango season approaches, the prices of mangoes are generally high, so people tend to buy them in smaller quantities. But when prices start falling, people prefer to buy larger quantities.

The quantity of a product that people are willing and able to buy at a particular price, depending on their needs, preferences, the season, trends, and income, is called the demand for the product.

Demand is not just the desire to buy something; it is the willingness complemented by the ability, or purchasing power, to buy it.

Purchasing power: It is a measure of how much one unit of a particular currency can buy at a particular time.

As with mangoes, when the price of any product rises, the quantity demanded decreases, and when the price falls, the quantity demanded increases. This phenomenon is called the Law of Demand, which highlights the inverse relationship between the price of a product or service and its quantity demanded.

Let us understand this with an example. At the beginning of the mango season, the price of mangoes was very high, ₹150 per kg. Srivalli, a consumer, bought only 1 kg. As more mangoes became available in the market over time, the price fell to ₹100, so she bought 2 kg, and later, when the price dropped to ₹50 per kg, she bought 3 kg. The quantity of a good or service that an individual consumer wants to buy at different prices, keeping other factors constant, is known as individual demand. For Srivalli, individual demand is shown in the table below, which is also known as the ‘demand schedule’. This demand schedule, when represented graphically, is called the ‘demand curve’.

The y-axis in Fig. 9.2 (b) represents the price of mangoes (in ₹), and the x-axis shows the quantity of mangoes demanded (in kg). Srivalli bought 1 kg of mangoes at ₹150 (represented at point A). But as the price fell to ₹50, she bought 3 kg (at point C). When the points of intersection, such as A, B, and C, are connected, the downward-sloping line DD’ is called the demand curve. The downward-sloping individual demand curve represents the inverse relationship between price and the quantity of a product demanded by the buyer, assuming other factors like income, taste, etc., are constant.

What happens when others want to buy mangoes too? The total quantity of mangoes demanded by all potential buyers at different prices is known as market demand, that is, the sum of all individual demands. Let us consider two more consumers, Alex and Israt, whose individual demands are given in the schedule below:

Table 9.1. Individual and market demand schedule

Price	Q1 (Srivalli)	Q2 (Alex)	Q3 (Israt)	Market Demand (QD)
₹150	1 kg	2 kg	3 kg	6 kg
₹100	2 kg	4 kg	6 kg	12 kg
₹50	3 kg	6 kg	9 kg	18 kg

By summing the demand of all three consumers, Q1+Q2+Q3, the market demand QD is derived. When the market demand is plotted at different prices, we get the market demand curve DmDm’ as shown in Fig. 9.3 (b).

Other Determinants of Demand

When a new model of a popular smartphone is launched, long queues and pre-bookings indicate the rush to buy it, even if it is more expensive. So, the demand for a product does not necessarily change only because of the price. Many other factors influence how much people want to buy, even when the price of the good or service remains the same. Let us see some of these factors at play.

Related goods: Products whose demand is interconnected, meaning a change in the price or availability of one directly affects the demand for the other.

Other Determinants of Demand
Price of Related Goods	The demand for a good can be affected by changes in the prices of related goods. There are two types of related goods: 1. Substitute Goods – These goods can replace each other, like tea and coffee. If tea’s price remains the same while coffee becomes more expensive, people who consume coffee may switch to tea, thereby increasing its demand. If Srivalli cannot afford to buy mangoes at the market price, she may buy bananas. When the price of a good rises, people tend to replace it with a relatively cheaper alternative. Hence, if the price of the substitute good increases, the demand for the other related good will increase. 2. Complementary Goods – These goods are generally used together to provide utility to the consumer, for instance, smartphones and earphones, or cars and petrol. If the demand for printers increases, the demand for printer cartridges may also rise, even though the price of cartridges remains unchanged. Similarly, if movie tickets become more expensive, people may refrain from going to the cinema, so the demand for popcorn sold in cinema halls may also fall.
Income of the Consumer	When household income rises, consumers can afford to buy more or choose higher-quality products. A rise in income generally makes people feel more confident about their ability to spend, so the quantity demanded of several goods rises, even if prices remain the same.
Taste and Preference of the Buyer	Every consumer has specific tastes and preferences for certain products, which determine their demand. For example, Srivalli likes mangoes and cannot replace them with oranges, even if oranges are cheaper than mangoes. The demand also depends on the size and composition of the nation’s population. For example, being the most populous nation, India’s domestic consumer demand contributes to its economic growth. In addition, the population’s composition shapes the demand for different types of products and services. More children indicate increased demand for sports shoes, more working adults mean a higher demand for formal shoes, and more elderly people imply a higher demand for comfortable or orthopaedic shoes.
Seasonality	Have you seen crowded bookshops at the beginning of the new academic session? Or customers flocking to sweet shops during the festive season? Or sweaters and jackets being demanded during the winter season? This is because individuals may demand different products at different times of the year, and these changes often depend on weather, festivals, and cultural habits rather than the price of the good.
Future Price Expectations	Future price expectations influence current demand even when current prices have not changed. If consumers expect prices to fall, they postpone purchases, decreasing present demand. If they expect prices to rise, they buy immediately, increasing present demand. For example, people delay buying durables before Diwali or the New Year, expecting festival discounts.

Supply

Supply is the quantity of a product that sellers are willing and able to offer at a particular price. As the price increases, the quantity supplied increases, and as the price decreases, the quantity supplied falls. This is so because higher prices increase profitability, incentivising producers to increase output, and also attract new firms to the market. This is known as the law of supply. Individual supply is the quantity a particular seller offers at different prices.

At the start of the mango season, supply is low, making mangoes costly. Mid-season, the supply increases and prices fall. This shows how prices depend on the interaction between demand and supply. When supply is less than demand, prices rise; when supply exceeds demand, prices fall.

Market supply is the sum of all individual supplies. For example, when mango prices are ₹50/kg, a seller supplies 1 kg; at ₹100/kg, he supplies 2 kg; at ₹150/kg, the seller supplies 3 kg. This pattern of higher prices leads to a greater quantity supplied, which gives an upward-sloping supply curve, as shown in Fig. 9.4.

Now consider three sellers, A, B, and C, in the market, who offer mangoes for sale in different quantities at different prices. So, their supply schedule is as follows:

Table 9.2. Supply schedule of sellers

Price	Seller A	Seller B	Seller C	Market supply (kg) (A+B+C=QS)
₹50	1	3	2	6
₹100	2	4	6	12
₹150	3	7	8	18

By combining the quantity supplied by all three sellers (A + B + C), the market supply Qₛ is derived. By plotting the market supply with the corresponding prices, the market supply curve is obtained.

Other Determinants of Supply
Price of Related Goods	Suppose a farmer faces two choices. If wheat prices are low but chickpea prices are high, he will grow more chickpeas in the next season. Therefore, the supply of one good depends on the profitability of other alternatives for the supplier.
Number of Sellers in the Market	If there are more sellers in a market due to higher competition and increased production, the market supply of the product would exceed demand. As a result, prices would fall. Likewise, if there are fewer sellers in the market, supply would be lower than demand, and prices would rise.
Technology	Improvements in technology reduce the cost of production, allowing producers to produce and supply more, and vice versa. For example, with improved techniques such as drip irrigation and weather sensors, crop production may rise, leading to a higher supply. Similarly, the adoption of cold storage facilities for transporting mangoes to distant markets increases market supply.
Future Expectations	If producers or suppliers expect a boom in the demand for goods in the near future, they will produce more, and supply will rise. Similarly, if producers expect lower demand, they will reduce production, leading to a fall in supply. For instance, if potato wholesalers expect prices to rise during the peak season, they might hold back supply now to sell later at higher prices.

Market Equilibrium

Market equilibrium: It is the point where the supply of goods and services equals demand, meaning there is no excess supply (surplus) or excess demand (shortage) in the market, and prices tend to remain stable unless external factors change.

Every market involves negotiation between what buyers are willing to pay and what sellers are willing to accept. Thus, prices are determined by the interaction between demand and supply. The table below shows the quantities of mangoes demanded and supplied at the selected prices. At a lower price, there is excess demand, whereas at a higher price, there is excess supply.

Table 9.3

Price (₹)	Quantity Demanded (Qd) of Mangoes (in kg)	Quantity Supplied (Qs) of Mangoes (in kg)	Quantity Supplied and Quantity Demanded	Outcome
40	38	6	Qs < Qd	Excess Demand
100	12	12	Qs = Qd	Market Equilibrium
150	8	43	Qs > Qd	Excess Supply
Equilibrium Price = ₹ 100		Equilibrium Quantity = 12 kg

At a price of ₹100, the quantity demanded equals the quantity supplied. This point is known as the market equilibrium. At this point, there is no pressure for prices to change, and the market is ‘cleared’, which means that there is neither a shortage (excess demand) nor a surplus (excess supply).

Let’s Analyse

Using data from Table 9.3, plot the demand and supply curves at the three prices, i.e., ₹40, ₹100, and ₹150. Identify and mark excess demand and supply on the graph. Think about how equilibrium could be reached in these scenarios.

Does Market Equilibrium Exist in the Real World?

In theory, equilibrium is an intersection point between demand and supply. But in the real world, markets are dynamic, with constantly changing conditions. For example, changes in technology, wages, interest rates, as well as wars, political events, pandemics, weather, and natural disasters, alter demand and supply. Therefore, ‘equilibrium’ in the real world is never stable and moves all the time, i.e., the market is always in a process of adjusting to a new equilibrium, never fully settling at the previous one. For example, during the COVID-19 pandemic in 2020, the demand for face masks surged rapidly. As a result, the supply could not catch up immediately, and the price of masks rose significantly. Over time, suppliers adjusted to the increased demand, and prices fell. Once the pandemic was over, demand decreased further, and prices fell to pre-pandemic levels.

Revenue: Total amount of money a business earns from the sale of goods or services, or other operating activities, before any expenses are deducted.

Tariffs by Hotels: An Example of Dynamic Markets

Hotels do not charge the same price (also called tariff) for rooms all the time. Their prices change according to demand, season, and special situations. This shows how markets are dynamic, meaning prices keep changing based on varying conditions.

Suppose a hotel in Goa has 100 rooms. The room tariff changes as follows:

• Off-season weekday (Monday in July): ₹1,500 per night
• Weekend during tourist season (Saturday in December): ₹8,000 per night
• New Year’s Eve (very high demand): ₹25,000 per night

If a group tour cancels its booking, the hotel may reduce the tariff by 40 per cent overnight to quickly fill empty rooms. Hotels may also change the tariff several times in a day to earn maximum revenue. These tariff changes depend on other factors such as:

• How fast rooms are getting booked
• Tariffs charged by nearby hotels
• Festivals, conferences, or events in the area
• Weather forecasts
• Number of days left before arrival
• Past booking trends

This example shows how prices in a market change with changes in demand and supply in real-world markets.

THINK ABOUT IT

Can you think of another real-life example (other than hotels) where prices change frequently? Explain why the prices keep changing.

Our choices today affect future resources. For example, high demand for fast fashion, overfishing and overuse of groundwater can harm future supply. So, should we focus only on short-term gains, or also think about long-term sustainability? How could this affect the market equilibrium?

Role of Government in the Economy

Today, India is the fourth-largest economy in the world. It is a market-based, regulated economy in which prices depend on demand and supply. However, markets do not always work fairly. Markets allocate goods and services based on willingness and ability to pay. Suppose essential goods like medicines become very expensive. Will they be accessible to all? In such cases, fairness and equity in allocation are required, particularly to ensure the welfare of vulnerable and low-income groups. So, the government plays an important role in the economy in the following key aspects.

Regulation of Unfair Practices

The government regulates unfair practices to protect consumers, workers, and producers from exploitation and injustice. For example, the government sets maximum prices (price ceiling) for essential goods like medicines to prevent overcharging. Similarly, the government sets a minimum wage to ensure workers earn enough for their hard work. This lower limit is known as the price floor.

Sometimes, a single seller or a few sellers dominate the market; they can charge higher prices and supply less than a competitive market would. This form of monopoly would be detrimental to consumer welfare as it may lead to higher prices, poorer quality of goods and services, restricted supply, and so on. The government regulates such practices by keeping prices and the quantity supplied in check.

Price ceiling: An imposed price control that sets the maximum amount a seller can charge for a product or service.

Price floor: An imposed limit on how low a price can be charged for a product, good, or service. For a price floor to be effective, it must be set above the market equilibrium price.

Monopoly: A market structure with a single seller or producer controlling the entire supply of a unique product or service, facing no close substitutes, allowing them significant power to set prices and output.

Many regulators, such as the Reserve Bank of India (RBI) for banking, the Central Consumer Protection Authority for violations of consumer rights and unfair trade practices, the Telecom Regulatory Authority of India (TRAI) for the telecommunications sector, the Securities and Exchange Board of India (SEBI) for the securities market, and so on, ensure transparency in the market. Do you remember some regulators from the Grade 7 Social Science textbook chapter ‘Understanding Markets’?

During COVID-19, the demand for sanitisers surged, leading to stockouts and sharp price increases. Some shopkeepers began hoarding and black-marketing. The government intervened by declaring sanitisers essential commodities under the Essential Commodities Act, 1955, capping the maximum retail price at ₹100 for 200 ml bottles. Meanwhile, many companies started production, and sanitisers soon became widely available at fair prices. How do such price controls affect suppliers and consumers? While in this case the price control was for an emergency, do you think such controls should be in practice forever?

Hoarding: Accumulation of goods, commodities, or money by individuals, or firms beyond what is immediately necessary, typically driven by fear of future shortages, anticipated price increases, or speculative motives.

Black Marketing: The illegal trade of goods and services that are banned or regulated.

Provision of Public Goods

Public goods are goods and services that are provided by the government for the benefit of all citizens. For example, roads, bridges, public parks, and street lighting are provided for public use; national defence protects the country from external threats; sanitation and drainage systems improve living conditions, and so on. These goods are usually not provided by private companies because they do not generate direct profit. Suppose your neighbourhood needs a park. Building it is expensive, but many families would benefit from it. If each family contributed ₹5,000, the park could be built. However, many families may think, “If others pay, the park will be built anyway, and I can use it without paying.” Because of this thinking, not enough money is collected, and the park is never built, even though everyone needs it. This explains why goods that benefit everyone often require government provision or funding to ensure social welfare, economic development, and equal access to essential services.

LET’S EXPLORE

From your surroundings, list two goods or services that are provided by the government (for example, roads, streetlights, parks, police, and so on). Choose one of the goods you listed and answer:

→ Who benefits from it?

→ Why would it be difficult for a private company to provide this service on its own?

→ Imagine the government stops providing this good or service. What problems might people in your area face?

Limitations of Government Intervention

Although government regulations are required when markets are inefficient, they must be implemented carefully, as excessive government intervention can have adverse effects.

S. No.	Impact	Explanation
a)	Price Distortions and Reduced Producer Incentives	When the government fixes prices below market levels, producers may lose motivation to supply goods or services. For instance, if the government sets a maximum price for wheat at ₹20 per kg while the market forces set it at ₹30 per kg, farmers receive less than what they would in a free market. This may lead to reduced production and shortages.
b)	Compliance Burdens	Government intervention often requires extensive regulations, licenses, permits, and compliance procedures. This can hurt businesses, especially small enterprises, and hamper ease of doing business. For instance, a small restaurant may need multiple permissions related to food safety, fire safety, pollution control, and local clearances. The time and cost involved can discourage small entrepreneurs from starting or expanding businesses.
c)	Discourages Innovation and Entrepreneurship	Heavy regulation and price controls reduce incentives to invest in new ideas or better technology. For example, in the case of price distortions, farmers won’t invest in better seeds, irrigation, or technology if they cannot earn adequate returns. This reduces long-term productivity and output.

Ease of doing business: How simple it is to start, run, and close a business in a country, measured by regulations, bureaucratic efficiency, and legal frameworks.

LET’S RECALL
In the chapter ‘Democracy’, you have read that a democratic government is accountable to the people and is expected to act in their interest.
→	According to you, how should a democratic government decide when and how much it should intervene in markets to protect people’s welfare?
→	Whose voices should a democratic government consider while making such decisions—consumers, producers, workers, or others? Why?

Understanding how these economic systems work and the general principles of economics helps us see the logic behind the choices people make, whether it is the price they pay, the jobs they do, or the policies governments implement. It provides the tools to think critically, use resources wisely, and make informed decisions in a world where every choice affects individuals, society, and the economy.

Markets are not machines with fixed equilibria but dynamic systems that constantly adapt, evolve, and respond to changing conditions. The next time you notice a price change—whether it is books, vegetables, or sports equipment—pause and ask, what is really happening here? Is supply changing? Is demand shifting? Is the market moving toward equilibrium or being pushed away from it? Is government intervention helping or hurting? While understanding these forces, you are not merely learning key principles in economics; instead, you are decoding how market dynamics work in real life.

Before We Move On

→

Demand is the quantity consumers are willing and able to buy at different prices. The Law of Demand shows an inverse relationship, that is, as price falls, quantity demanded rises. Demand is influenced by income, prices of substitutes and complements, tastes, seasonality, future expectations, and population.

→

Supply is the quantity sellers are willing and able to offer at different prices. The Law of Supply shows a direct relationship—as price rises, quantity supplied increases. Supply depends on prices, related goods’ prices, the number of sellers, technology, input costs, and other factors such as weather.

→

Market equilibrium occurs when the quantity demanded equals the quantity supplied. Fundamental markets constantly adjust toward a new equilibrium as conditions change—weather, trends, technology, income, and so on, creating dynamic pricing conditions.

→

Government intervenes when markets fail and produce unfair outcomes (unaffordable essentials), under-provide public goods, and enable monopolies. However, excessive government regulations may also have adverse effects.
