To calculate the interest on a monthly basis, we need to know the interest rate or the annual interest percentage. For 2 Rupees interest per month means Rs. 2/- as interest on Rs. 100/- that is 2% per month. Here annual interest rate for Rs. 100 is Rs. 24 that is 24% p.a.

Simple Interest formula: Interest = (Principal * Rate * Time) / 100


Principal is the initial amount
Rate is the annual interest rate (in percentage)
Time is the time period in years for which the interest is calculated (here, it will be 1/12 if we’re considering one month)

Compound Interest

Interest = [P (1 + R/)^n *T] – P


I = Value of interest

R = rate of interest (in decimal format)

N = number of periods the interest gets compounded,

T = time period/tenor/duration

Using the above simple and compounding interest formulae we can calculate Interest for different amounts
