Free Compound Interest Calculator – See Your Money Grow

Simple interest is calculated only on the original principal, while compound interest is calculated on the principal plus all previously earned interest. Compounding makes your money grow faster over time, and the difference becomes larger the longer the period.

The more often interest compounds — yearly, quarterly, monthly, or daily — the more interest you earn, because interest is added to the balance more frequently. The calculator lets you change the frequency to see this effect directly.
