Simple Interest Calculation: Formula and Example

Formula for Calculating Simple Interest

Calculating simple interest is a straightforward process that can be done using a simple formula. The formula for calculating simple interest is:

Simple Interest = Principal × Rate × Time

Where:

  • Principal is the initial amount of money
  • Rate is the interest rate per period
  • Time is the number of periods

Simple Interest = $1,000 × 0.05 × 2 = $100

So, the simple interest on $1,000 at an interest rate of 5% per year for 2 years would be $100.
