What is compound interest?


Compound interest is a way of earning interest on both the money you initially put in and the interest that money earns over time. Here’s how it works: let’s say you deposit Rs. 100 into a savings account that pays compound interest. The bank calculates interest not just on the Rs. 100 you deposited, but also on the interest that Rs. 100 earns over time.

Now, here’s why compound interest is powerful: Over longer periods, your money grows faster because each time interest is added, it’s based on a larger amount – your original money plus the interest it has already earned. This means your savings can grow significantly over time. It’s like a snowball effect where your savings build on themselves, helping you reach your financial goals sooner.

A = P (1 + R / n) ^ (nT)


A = Future value of the investment
P = Principal amount
R = Interest rate (as a decimal)
n = Number of compounding periods per year
T = Time period (in years)

The calculator applies this formula to compute the total amount accumulated at the end of the investment duration, taking into account the principal amount, interest rate, compounding frequency, and investment period. This calculation provides insight into how the investment grows over time, including the compounded interest earned.

Difference between simple interest and compound interest calculation

Differentiating between simple interest and compound interest is crucial for understanding how investments grow over time.

Simple interest is calculated only on the principal amount of an investment or loan. It remains constant throughout the investment period, regardless of how much interest has been accumulated. Compound interest, on the other hand, takes into account not only the initial principal but also the accumulated interest from previous periods. This means that each time interest is calculated and added to the principal, the next calculation is based on a larger amount. As a result, compound interest grows faster than simple interest over time, leading to exponential growth in investments.

Here's a comparison table highlighting the key differences between simple interest and compound interest:

Aspect Simple interest Compound interest
Calculation Interest is calculated only on the principal Interest is calculated on principal + accumulated interest
Growth Linear growth Exponential growth
Formula I = PxRxT A = P (1 + R / n) ^ (nT)
Effect of Time Interest amount remains constant Interest amount increases over time
Application Commonly used for short-term loans or simple savings accounts Commonly used for long-term investments and savings
