How to Calculate Fixed Deposit?


If you want to gain more from your investment, you should know how the interest on FD is calculated. There are two methods of calculating interest on a fixed deposit, and they are:

Simple Interest Method

Under this method, you multiply the principal amount, rate of interest and tenure to get the result. The formula used is:

Simple Interest (SI) = P (Principal amount) x R (Rate of interest) x T (Tenure) divided by 100 or P x R x T/100

For instance, if you invest Rs 10,000 @ 6% p.a. for 5 years, you get:

10,000 x 6 x 5/100 = Rs 3000

You will earn Rs 3000 in 5 years.

Compound Interest Method

The compounding method enables you to earn interest on the interest, and most banks offer compound interest to attract FDs. For example, if you invest Rs 10,000 @ 6% p.a. for 5 years, you get:

In the first year:  10,000 x 6 x 1/100 = Rs 600, so the total amount is Rs 10,600

In the second year: 10600 x 6 x 1/100 = Rs 636, so the total amount becomes Rs 11236

In the fifth year, you get Rs 13,469, where the interest earned is

To simplify the calculation, you can use this formula

Compound Interest (CI) = P {(1 + i/100) n – 1}, where

Compound Interest (CI) = 10000 {(1 + 6/100)5 – 1} = Rs 3,469
