Compound interest is essentially a type of return with which your savings can see a good amount of growth. More complicated than simple interest, compound interest is an important factor to consider when you’re getting returns on your savings or deposit. Let us learn more about what is compound interest, what is the formula of compound interest and what it does to your money in the long run.
Compound interest is interest earned on interest. Compounding occurs when you earn returns on the principal amount and the interest previously earned. In an account where you are earning simple interest, you only get interest on the principal amount. An account that offers compound interest allows interest to be earned over not just the principal, but also the interest you may have earned.
Compound interest can be confounding for a first-time reader. Let us try to simplify it with its mathematical formula and then, with the help of an example:
The compound interest formula is:
A = P (1 + (r/n)) ^ nt
A = final amount you will receive
P = the initial principal amount
r = interest rate
n = number of times interest is applied
t = time passed (in years)
Now, let us look at a simple example to understand it better and to see how compounding benefits you. Suppose Ajay opened a bank account with an institution that offered a monthly compound interest of 4%. For convenience, let us assume Ajay is not depositing or withdrawing any money from this account for some time.
After the first month, Ajay's bank account was credited with ₹1200 on the current balance of ₹30,000. In the next month, he earned an interest amount of ₹1248. This interest was not drawn on the principal amount (₹30,000) but on the interest plus the principal amount, which was ₹31,200. In the third month, he earned an interest amount of ₹1297, and so on.
On an account offering a simple interest rate, Ajay would have earned only ₹1200 each month.
Many investment instruments use compounding to multiply your money. Mutual funds are one of them, and you can invest in any mutual fund of your choice on IDFC FIRST Bank.

Compounding allows you to earn interest from the principal amount and the interest previously generated on this amount. The interest earned becomes a part of the principal, on which the future interest will be drawn.
The rate of interest differs from bank to bank. The compounding rate of interest may also depend upon the type of bank account that you have.
