What It Is
How It Works
Why It Matters
Simple interest is a handy, easy tool for estimating the interest earned or paid on a certain balance in one period. However, it does not take into account the effects of compounding, which is the process of earning interest on principal plus interest that was earned earlier. This means it can dramatically understate the amount of interest earned or paid over time.
