💰 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.
Note: The APY here is treated as a fixed estimate for the full period. It does not mean any institution will offer or maintain the same yield.
Results on this page do not automatically include fees, withdrawals, taxes, inflation, rate adjustments, or tiered account rules.
If the estimate becomes too large, the page stops rendering 2-decimal money outputs because the local double-precision model can no longer support cent-level precision responsibly.
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.
