What is Simple Interest?

Simple Interest is a method of calculating the interest amount for a principal amount over a specific period. It is commonly used in banking and finance to calculate short-term loans or deposits.

Formula: Simple Interest = (P × R × T) / 100

  • P = Principal Amount
  • R = Rate of Interest per annum
  • T = Time in years

This calculator helps you compute the total interest and final amount you’ll receive or pay based on the given values. You can use it for personal loans, savings accounts, fixed deposits, and more.
