## What is Simple Interest?

Simple interest, a fundamental concept in finance, refers to the interest earned or paid on a principal amount over time. Unlike compound interest, simple interest does not accumulate on previously earned interest.

Simple interest is the cost of borrowing money or the return on investment without the compounding factor. It is a linear calculation, making it easy to understand and apply in various financial scenarios.

## Simple Interest Formula
