Money Concepts
Money is what we use to buy things instead of trading items, and it comes in forms like coins, notes, and digital money, so think about what you last bought as we learn fun ideas like saving, spending, and interest.
What are Money Concepts in Math?
In mathematics, money concepts involve calculations related to value, interest, and growth over time. Key mathematical concepts related to money include percentage, which is used to calculate interest rates, discounts, and inflation.
We also use compound interest to calculate the interest earned on the initial investment and on previously accrued interest. These concepts help students understand how a business manages its finances and evaluates its economic trends.|
For example, if you invest ₹1,000 at 10% interest per year, the amount grows each year not just on the ₹1,000, but also on the interest you’ve already earned.
Types of Money Concepts
The meaning of money and how it works are learned through the various types of money concepts. Some of the types of money concepts are mentioned below:
Currency Types:
- Fiat Money: Fiat money is the government-issued money with no intrinsic value. Examples of fiat money are paper bills and coins.
- Commodity Money: Commodity money is the money that is backed by a physical commodity like gold or silver.
- Cryptocurrency: Cryptocurrency is digital or virtual currency that uses cryptography and blockchain technology. For example, Bitcoin and Ethereum.
Value Concepts:
- Purchasing Power: Purchasing power means the value of money in terms of the goods and services it can buy.
- Inflation and Deflation: Inflation and deflation are the changes in the value of money that are caused by price level changes in the economy of a particular country or region.
Financial Concepts:
- Interest Rates: Interest rate refers to the money an individual or an organization must pay after borrowing a certain amount of money (principal amount). The interest amount is the monthly or weekly payment done until the full repayment of the principal amount.

- Discounting: Discounting means finding out how much a future sum of money is worth today.
Transaction Concepts:

Common Mistakes and How to Avoid Them in Money Concepts
Students tend to make mistakes while handling or understanding money concepts. Here are some of the common mistakes students make and the solutions they can follow to overcome them:
Mistake 1
Confusing “Needs” with “Wants”
Students must categorize the expenses based on their spending habits and see what are the basic needs and what are the wants. After this, they can cut off on particular wants and focus on saving some money.
Mistake 2
Ignoring budgeting
Students must practice saving their money by planning a budget based on the income and expenses. After this, they can track all the expenses and incomes to see where most of the money is flowing to.
Mistake 3
Ignoring inflation
Students must know what inflation is and always keep a track on their long-term goals (like retirement) by considering how inflation affects their costs. They must consider inflation before investing in different types of stocks and keep checking the market.
Mistake 4
Overspending on credit
Students must use credit cards wisely if they have one. Spend using credit cards only if you know that you can pay the amount later. They must always remember to pay on time, if not it will impact their credit score.
Mistake 5
Not saving for emergencies
Students can build an emergency fund, where they can save money by cutting down on unwanted expenses. They can also set up an autopay transfer to their savings account allocated for the emergency fund.

Solved Examples on Money Concepts
Problem 1
John deposits $5000 in a bank account that offers a 5% annual simple interest rate. How much interest will he earn after 3 years?
John will earn $750 in interest after 3 years.
Explanation
Step 1: Write the formula for simple interest
\((P × R × T) / 100 \)
where P, R, and T stands for principal, rate, and time respectively.
Step 2: Identify the values
P = 5000
R = 5%
T = 3 years
Step 3: Substitute the values
SI =\( \frac{(5000 × 5 × 3)}{100}\)
= \(\frac{75000}{100}\)
= 750
Problem 2
Alice invests $2000 in an account that offers 8% annual compound interest. How much will she have after 2 years?
Alice will have $2332.80 after 2 years
Explanation
Write the formula for compound interest:
\(A = P \left(1 + \frac{R}{100}\right)^T \)
Identify the values:
P = 2000
R = 8%
T = 2 years
Substitute the values:
\(A = 2000(1 + (8/100))^2\)
\(A = 2000(1.08)^2\)
A = 2000 x 1.1664 = 2332.8
Problem 3
A laptop originally costs $1200. It is on sale with a 15% discount. What is the final price after the discount?
The laptop costs $1020 after discount.
Explanation
Discount amount:
\(Discount = \frac{15}{100} × 1200 = 180\)
Final price after discount:
\(Final price = 1200 − 180 = 1020\).
Problem 4
Sarah is traveling to Europe and needs to convert $500 into Euros. If the exchange rate is 1 USD = 0.85 EUR, how many Euros will she get?
Sarah will get 425 Euros.
Explanation
Convert the USD into Euros using the formula:
Euros = \(500 x 0.85 = 425\)
Problem 5
Emma earns $3000 per month. She follows the 50/30/20 rule. How much does she allocate to each category?
She allocates $1500 to needs, $900 to wants, and $600 to savings.
Explanation
Needs (50%):
\(\frac{50}{100} × 3000 = $1500\)
Wants (30%):
\(\frac{30}{100} × 3000 = $900\).
Savings (20%):
\(\frac{20}{100} × 3000 = $600.\)
