💰 Savings Calculator

Estimate ending balance, total contributions, and interest earned from an initial deposit, fixed monthly contribution, time horizon, and estimated APY. Educational estimate only; not financial, investment, tax, legal, or accounting advice.

This tool estimates savings growth from a single model: initial deposit, fixed monthly contribution, fixed time horizon, and a fixed estimated APY. The page converts APY into an effective monthly rate and iterates with interest applied first, then the monthly contribution added at the end of each month. Amounts stay in your input currency unit.

This estimate does not automatically include rate changes, fees, withdrawals, taxes, inflation, tiered rates, or other account rules.

Amount inputs support up to 2 decimal places. Estimated APY supports up to 4 decimal places. Time horizon supports whole months or whole years only.

You can interpret `5 years` as `60 months`; this model always treats the monthly contribution as an end-of-month deposit.

If the result grows beyond a safe precision range, the page blocks it instead of pretending the output is still accurate to cents.

Disclaimer: This tool is for educational estimation only. It is not financial, investment, tax, legal, or accounting advice, and it is not a product recommendation, forecast, or guarantee. Actual APY, fees, withdrawal rules, compounding methods, and account terms depend on the institution and account you use.

Privacy note: Calculations run locally by default. Your savings inputs are not uploaded.
