## What is Compound Interest?

Compound interest is the interest calculated on both the original amount of money you save or borrow and the interest that has already been added. This simply means adding the earn interest on your interest.

Understanding how to calculate compound interest is indeed important.

Let’s see how compound interest works in loan and FDs.

**Compound Interest in Loans**

When you take a loan, the interest you owe is calculated on the initial principal plus any interest that has already been added. This means you can end up paying more over time. This happens especially, if the loan period is long.

Let us say you borrow ₹10,000 at a 5% annual interest rate. Here, the interest will be added each year, and the next year you will pay interest on the new total.

**Compound Interest in Fixed Deposits (FDs)**

When you invest money in a fixed deposit scheme, the bank pays interest not just on your initial amount but also on the interest that has been added over time. This could be yearly or bi-yearly.

**Note- **Compound interest is applicable only on the FDs with long term tenure.

Let us say, you invest ₹10,000 at a 5% interest rate, after one year, you’ll earn interest on ₹10,500 (the principal plus interest).

In simple terms:

**Simple Interest**: You earn interest only on the original amount. Know how a**simple interest calculator**works.**Compound Interest**: You earn interest on both the original amount and the interest that gets added over time.

**How to Calculate Compound Interest**

To calculate compound interest, a simple formula is used globally:

**A = P (1 + r/n) ^ nt**

Here’s what each part of the formula means:

**A**= Final amount (your principal + interest)**P**= Principal (the initial amount of money you invest or deposit)**r**= Annual interest rate (in decimal form)**n**= Number of times interest is compounded.**t**= It represents the number of times the money is invested or borrowed for (in years)

Let assume that invest ₹40,000 at an annual interest rate of 8% for 3 years.

As per the terms shared, the interest will compound once a year.

The compound interest for the first year will be:

₹40,000 x (8/100) = ₹3,200

For the second year, the compound interest will be calculated on ₹43,200 (₹40,000 + ₹3,200).

So, the new interest will be:

₹43,200 x (8/100) = ₹3,456

By the third year, the amount grows to ₹46,656, and the interest will be:

₹46,656 x (8/100) = ₹3,732.48

As you can see, each year you earn interest not only on the initial ₹40,000 but also on the interest you’ve already earned.
