How Simple Interest Works

Simple Interest is interest calculated only on the principal amount, not on accumulated interest.

Formula: SI = (P × R × T) / 100

  • P = Principal (initial amount)
  • R = Annual interest rate (%)
  • T = Time period (in years)

Total Amount = Principal + Simple Interest
