Simple interest

Definition

Simple interest is a method of calculating the interest charged or earned on a principal amount over a specified period of time, typically expressed as a percentage. It is calculated using the formula: Simple Interest = Principal × Rate × Time, where the rate is the annual interest rate and time is in years. This straightforward approach allows for easy understanding of how much interest accumulates on loans or investments, making it essential in the context of long-term liabilities.
