How to use this calculator
How the monthly amount is estimated
Existing savings are grown for the selected months. We then solve for an equal contribution at the end of each month that reaches your target. An APY of zero assumes no interest.
Understand the growth assumption
APY is a hypothetical annual yield, not a forecast or promise. Actual bank rates can change. The calculation converts the annual yield into an effective monthly rate.
What is excluded
Taxes on interest, account fees, inflation, changes to yields and irregular contributions are not included. If your existing savings already exceed your target, no additional monthly contribution is needed.
