Calculating compound interest is a great way to grow your investment. It gives you returns not just on your principal investment but also on the interest that piles up on that initial money.

Suppose you decide to invest 100 (USD/INR/EURO) in a fixed deposit offering a 5% annual interest rate. After the first year, your investment grows to 105 (USD/INR/EURO). Now, when the interest is recalculated for the following year, it's based on the new total of 105 (USD/INR/EURO) instead of the principal 100 (USD/INR/EURO).
This means the interest for the next year will be earned on the updated balance (105), allowing your money to potentially grow faster due to this compounding effect.

## Compound Interest formula

A = P(1 + r/100) ^ nt

• r is the interest rate per year.
• n is how many times the interest is applied per year.
• t is the number of years you leave the money invested.
• A is the total amount you'll have at the end.
