How Compound Interest Works

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods. It is the reason why starting to invest early is heavily recommended.

This calculator assumes interest is compounded monthly, which is standard for most investment returns tracking and savings accounts.
