About the Simple Interest Calculator

Simple interest is calculated only on the original amount, so it grows by the same amount each year. It is common in short-term loans and some deposits.

Enter the principal, rate and years to see the interest and the total.

Formula used

Interest = P × r × t ÷ 100, where P = principal, r = annual rate and t = years.

Frequently asked questions
