What Is Simple Interest?

Simple interest is calculated only on the original principal amount. It does not compound over time, making it easy to calculate and understand.

Simple Interest Formula

Interest (I) = Principal (P) × Rate (R) × Time (T)

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

Example

Principal: $10,000
Rate: 5%
Time: 3 years

Simple Interest = $1,500
Total Amount = $11,500
