How much to save each month
Turn a goal and deadline into a recurring contribution.
Free savings planner
Turn a target into a practical saving plan. Calculate the recurring amount needed by a deadline, or estimate when your current plan could reach the goal.

Understand the plan
The APY is converted to an effective rate for your saving frequency using (1 + APY)^(1 / periods per year) - 1. For a deadline plan, the calculator grows your current savings to that deadline and solves the future-value-of-an-annuity formula backwards for the recurring deposit. The amount is rounded up to the nearest cent so rounding does not leave the plan below the goal.
For a time-to-goal plan, it finds the first saving period whose projected balance meets or exceeds the goal. Beginning-of-period deposits receive one additional period of assumed interest. The model uses equal periods rather than exact calendar dates.
The estimate assumes a constant APY and deposit amount. It excludes changing rates, fees, taxes, withdrawals, inflation, minimum-balance rules, and bank-specific rounding. It is an educational scenario, not financial advice or a guarantee.
Compare the goal-focused approach with the Investor.gov Savings Goal Calculator. To project an amount without solving for a goal, use our compound interest calculator.
Worked example
Choose a $10,000 goal, $0 already saved, 0% APY, and a one-year monthly deadline. Dividing the gap across 12 deposits gives $833.333…, so the calculator rounds the recurring amount up to $833.34.

The answer depends on the target, current savings, deadline, assumed APY, and deposit timing. The calculator solves those assumptions for the recurring amount.
Yes. Choose Time to goal and enter the amount you can save each period.
It is rounded up to the nearest cent so the displayed deposits do not leave the plan just below the target because of rounding.
Run separate scenarios. This model assumes one fixed APY for the entire period.
No. It excludes inflation, taxes, fees, withdrawals, and changing rates.
