What Is an Interest Calculator?

An Interest Calculator is an online tool that helps you quickly compute interest on savings, loans, or investments. You can enter details like the principal amount, interest rate, and time period, and the calculator instantly shows you the total interest payable or receivable.

This tool is especially useful for:

Types of Interest Calculated

  1. Simple Interest (SI):
    Simple Interest is calculated only on the principal amount.
    Formula: SI = (P × R × T) ÷ 100
    Where P = Principal, R = Rate of Interest, T = Time in years.
  2. Compound Interest (CI):
    Compound Interest is calculated on the principal plus accumulated interest.
    Formula: CI = P × (1 + R/100)^T – P

Your web app can compute both simple interest and compound interest instantly, saving you time and effort.
