Goal planning

Savings Goal Calculator

Estimate the monthly contribution needed to reach a target balance. The result assumes monthly contributions and monthly compounding.

Decision guide

Turn the monthly result into a resilient plan

A savings-goal calculation solves for the recurring amount needed to bridge a starting balance and a future target under an assumed rate. The answer is sensitive to deadline, contribution timing, and return. Build a plan that can still work if the rate is lower or one or two deposits are missed.

Use three contribution scenarios

For a five-year goal, calculate the required monthly deposit with your expected rate, then repeat at zero growth and at a lower rate. The zero-growth result is a useful ceiling because it shows what your cash flow must do without help from interest. Round the chosen deposit upward instead of budgeting to the cent.

Before you decide

  • Keep an emergency fund separate from the goal.
  • Use an after-fee rate assumption.
  • Add known one-time deposits on their expected dates.
  • Review progress at least when the rate or deadline changes.

Method and limitations

This calculator is a planning aid, not a guarantee. Investor.gov models contributions, time, rate, and rate variance as separate inputs for the same reason. For a market-based goal, consider downside scenarios; for a deposit account, verify APY, variable-rate terms, withdrawal limits, and insurance coverage.
