What is a Simple Interest Calculator?

A simple interest calculator is a straightforward online tool that helps you calculate the interest you will earn or need to pay on a loan or investment based solely on the original principal amount. Remember: It’s particularly useful for figuring out costs for short-term loans or the returns on simple investments, where the interest doesn't compound over time.

How Does a Simple Interest Calculator Work?

A simple interest calculator takes three main pieces of information: the amount of money you start with (the principal), the interest rate per period, and the number of time periods you want to calculate for. It multiplies these together to give you the total interest amount. To understand how to calculate simple interest, let’s know the following formula:

SI = P × R × T / 100

SI = simple interest
P = principal amount
R = the interest rate per annum
T = the time in years
