What is Compound Interest?
Compound interest refers to the interest that is earned or paid not only on the initial amount of money (the principal) but also on any interest that has been added to or earned over time. It is one of the most powerful financial concepts that allows money to grow exponentially over time.
With compound interest, the interest is added to the principal at specific intervals, such as daily, monthly, quarterly, or annually, depending on the terms of the financial arrangement or investment. Over time, this compounding effect significantly increases the total value of the investment or debt.
Why is Compound Interest Important?
Compound interest is a fundamental concept in personal finance and investment planning. Understanding how it works can help individuals and businesses make better financial decisions. Here are a few reasons why compound interest is important:
- Accelerated Growth: Money grows at a faster rate compared to simple interest due to the compounding effect.
- Long-Term Benefits: The longer the time period, the more significant the impact of compound interest.
- Encourages Saving: Understanding compound interest motivates individuals to save and invest early.
- Debt Accumulation: On the flip side, compound interest can lead to rapid debt accumulation if not managed properly.
What is the Compound Interest Formula?
The formula for calculating compound interest is:
A = P(1 + r/n)^(nt)
Where:
- A: The final amount of money after t years, including both the principal and the compounded interest.
- P: The initial principal amount.
- r: The annual interest rate (in decimal form, e.g., 5% = 0.05).
- n: The number of times interest is compounded per year.
- t: The number of years the money is invested or borrowed for.
The compounding frequency (n) plays a critical role in determining the final amount. For instance, if the interest is compounded annually, n is 1. If compounded monthly, n is 12. The more frequently interest is compounded, the higher the final amount.

Example of Compound Interest Calculation
Let’s consider an example to understand how compound interest works:
Scenario: You invest ₹10,000 at an annual interest rate of 5%, compounded annually, for 5 years.
Using the formula:
A = 10,000(1 + 0.05/1)^(1*5) = ₹12,762.82
After 5 years, your investment will grow to ₹12,762.82, including ₹2,762.82 as interest.
Factors Affecting Compound Interest

- Principal Amount: Higher principal amounts lead to more significant compounding effects.
- Interest Rate: Higher rates result in faster growth.
- Compounding Frequency: More frequent compounding increases the final amount.
- Time Period: Longer time horizons amplify the compounding effect.
