Savings Calculator
Plan monthly savings toward a goal with interest included.
Quick answer
A savings balance with regular deposits grows to the future value of the starting amount plus the future value of the contributions, both compounded at the account's APY. Saving earlier matters more than saving more, because early deposits compound for longer.

How the monthly amount is solved
The calculator inverts the future-value formula: your current balance grows at the account's yield, and the gap to the goal is filled by equal monthly deposits that each compound from the day they land. APY is treated as an effective annual rate and converted to its exact monthly equivalent.
Making the number smaller
Three levers shrink the required deposit: more time (the biggest one — compounding needs runway), a higher yield (high-yield savings and CDs beat checking accounts by several points), and a larger starting balance. If the monthly number looks impossible, stretch the timeline before abandoning the goal.
