Simple Interest Calculator – Calculate Interest on Your Investment or Loan

Whether you are taking a loan or investing money, knowing how much interest you will earn or pay is crucial. Use our Simple Interest Calculator to quickly determine your interest amount based on the principal, interest rate, and time period.

What is Simple Interest?

Simple Interest (SI) is the interest earned or paid on a principal amount over a fixed time period. It is calculated using a straightforward formula and does not compound over time, making it easy to compute.

Simple Interest Formula

The formula for calculating simple interest is:

SI = (P × R × T) / 100

Where:

  • P = Principal amount (Initial investment or loan amount)
  • R = Rate of interest per annum (%)
  • T = Time period (in years)

Example of Simple Interest Calculation

Assume you invest ₹10,000 at an interest rate of 5% per annum for 3 years. The interest calculation will be:

SI = (10,000 × 5 × 3) / 100 = ₹1,500

Thus, after 3 years, the total interest earned will be ₹1,500, making the total amount ₹11,500.
