Fixed Deposit (FD) is a widely used investment option to grow you wealth. It is offered by almost all banks, Post Office, and other non banking financial institutions. When you choose to invest in a Fixed Deposit, you lock your funds for a specific duration, during which they earn interest at rates that are significantly more attractive than what regular savings accounts offer.

You may calculate your savings or return on investment from fixed deposits using the FD calculator. All you need to do is input the principal amount, the prevailing interest rate, and the chosen tenure in years, and this tool will swiftly compute the projected maturity amount for you.

Formula To Calculate FD Maturity Amount

The maturity amount of Fixed Deposits can be determined manually or with the aid of an online calculator. The mathematical formula for FD calculation is shown below:

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


  • A = maturity amount,
  • P = principal amount,
  • r = annual interest rate,
  • n = number of times the interest rate is compounded in a year,
  • t = tenure in years.


If you invest ₹2,00,000 in an FD with an annual interest rate of 7%, compounded quarterly for 3 years. Using the formula:

A = ₹200,000 * (1 + 0.07/4)^(4 * 3)

A = ₹200,000 * (1.0175)^12

Calculating the value:

A = ₹243,813.02

Therefore, the maturity amount for an FD investment of ₹200,000 with a 7% annual interest rate compounded quarterly over 3 years would be approximately ₹243,813.02.

How To Use FD Calculator?

How Is Fixed Deposit Interest Calculated?

The maturity amount of the FDs can be determined manually or with the aid of an online calculator. The calculation's mathematical formula is shown below:

C.I = P [ { (1 + r/n)^nt } – 1]


C.I = compound interest,

P = principal amount,

r = annual interest rate, and

t = the tenure in years.

n = number of times the interest rate is compounded in a year


Let's consider an FD investment of ₹200,000 with an annual interest rate of 7% for a tenure of 3 years. Let’s assume, compounding is done annually.

P = ₹200,000

r = 7/100 = 0.07

t = 3

n = 1

Using the compound interest formula:

C.I = P [ { (1 + r/n)^nt } – 1]

C.I= [ { ₹200,000×(1+ 0.07)^3 } − ₹200,000 ]

C.I = ₹200,000 × [ {(1.07)^3 } - 1]

Calculating the value:

C.I = ₹45,008.60

In this case, the compound interest earned on the investment over the 3-year tenure would be approximately ₹45,008.60.
