Learn the Formula

Simple interest measures how much money is earned or owed based on the original amount, the annual interest rate, and the amount of time.

Simple Interest = Principal × Rate × Time    or    I = P × r × t
  • Principal (P) = starting amount of money
  • Rate (r) = annual interest rate written as a decimal or percent
  • Time (t) = number of years
  • Balance (A) = principal + interest
