What is a Simple Interest Calculator?

A Simple Interest Calculator is an online financial tool that helps individuals calculate the total interest earned on an investment or paid on a loan based on the principal amount, interest rate, and time period. It provides a quick and accurate estimate, making financial planning easier.

How Does a Simple Interest Calculator Work?

The simple interest loan calculator works on the basic simple interest formula:

SI = (P × R × T) ÷ 100
Where:

  • SI = Simple Interest
  • P = Principal Amount
  • R = Annual Interest Rate (in percentage)
  • T = Time Period (in years)

The total amount is calculated as:

Total Amount = P + SI
