How Simple Interest Calculator Works

Simple Interest (SI) is calculated on the principal amount over a fixed period at a fixed interest rate. This calculator helps you easily determine the interest earned and the total amount payable.

Simple Interest Formula

SI = P × R × T / 100

Where P = Principal, R = Annual Interest Rate (%), T = Time in Years

Simple Interest Calculation Example

If you invest 50,000 at 5% per annum for 3 years, the interest earned will be 7,500, and the total amount payable will be 57,500.
