**FD calculator** follows the basic formula of simple interest and compound interest to calculate the interest earned and the maturity amount.

In the case of simple interest, the interest is calculated on the initial principal amount using the following formula.

I =P x r x t ÷ 100

Where I = interest earned

P= Principal

r=rate of interest

t= tenure

In the case of compounding the interest, the following formula is used.

A = P (1+R/100) ^N

Where A stands for the maturity amount, P for the principal amount, R for the rate of interest and N for the number of months or years in the tenure.

For instance, if you are investing Rs 1,00,000 for 3 years at an interest rate of 10%, the calculation would be the following.

P= Rs. 100000

R= 10%

N= 3 (if compounded annually)

Placing the following values in the given formula, the maturity amount A = Rs. 132100

Thus, the interest earned over 3 years (I) = Rs. 32100.
