Calculate the interest you can receive by depositing in a Fixed Deposit.


If you want to put your money away for a longer period of time and even earn some interest on it, then you can get it through a fixed deposit. A fixed deposit is a long-term saving where you lock in your money and earn interest on your investment.

Fixed deposits are generally offered by banks, mutual funds, and non-banking finance companies(NBFCs).

How To Calculate The Fixed Deposit Interest?

There are 2 methods to calculate the interest on fixed deposit – simple interest and compound interest.

Simple Interest:

Simple interest is the amount of interest earned on a principal amount over time. It is calculated by multiplying the rate of interest per annum, the principal amount, and the number of years.

Formula to calculate simple interest:

SI = P x R x T/ 100


SI = Simple Interest

P = Principal amount

R = Rate of Interest

T = Tenure

Let’s consider an example:

If you deposit Rs. 5 lakhs at a 10% interest rate per annum for 6 years, then your interest amount at the time of maturity you will get:

SI = 5,00,000 x 10 x 6/100 = 3,00,000

Maturity Value = Principal amount + Simple interest

Therefore in our example Maturity Value = 5,00,000 + 3,00,000 = 8,00,000

Compound Interest:

Compound interest is the interest earned on both the principal amount and the interest amount. It is calculated by multiplying the principal amount by the interest rate raised by the number of years, the number of periods, for which the interest is compounded.

Formula to calculate the compound interest:

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


A = maturity amount

P = Principal amount

r = Rate of Interest (in %)

n = number of compounding in a year

t = number of years

For example:

if a sum of Rs 10,000 is invested for 3 years at 10% compound interest rate (quarterly compounding), then at the time of maturity,

A= 10,000 {1 + (0.1/4)} ^ (4 * 3)

A = 10,000 (1 + 0.025) ^ (12)

A = 10,000 (1.025) ^ (12) = Rs. 13,449 (approximately)

Compound Interest (CI) Earned over 3 years = Maturity Amount – Principal Amount

CI = 13,449 – 10,000 = Rs. 3,449
