Frequently Asked Questions

Monthly compound interest means that interest is calculated and added to the principal balance each month, so you earn interest on interest.

Enter your initial principal, annual interest rate, number of years, and any monthly contribution. Click 'Calculate' to see the future value.

Simply set the monthly contribution to 0. The calculator will still compute the compounded growth of your initial principal.
