Fixed deposit interest is calculated with the two following formulas.

For compound interest the formula used is:

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

In this given formula,

A is the amount received on maturity

t stands for investment tenure

r is the annual interest rate

P denotes the deposit amount

Lastly, n is equal to the number of times the interest is compounded.

However, to effectively understand how this calculation works, you can refer to the example illustrated below:

Consider investing ₹1 lakh for 5 years with a rate of 6.70% p.a at annual compounding.

In this scenario,

P is ₹1 lakh, r is 6.70% p.a., t is 5 years and n equals 1.

Therefore A = 100000 (1+0.067/1) ^ 1 x 5.

A = ₹1,39,407 and interest earned A-P =₹ (1,39,407 – 1,00,000) = ₹39,407.

On the other hand, the formula used in simple interest is M= P+ (PXRXT/100).

In this given formula,
