Free compound interest calculator for comparing initial investment, regular contributions, return assumptions, goal amounts, and CSV-ready growth tables.
- Calculations run in the browser and show principal, interest earned, total balance, and progress toward a target amount.
- The tool is educational and does not predict market returns, taxes, brokerage costs, inflation, or personal investment suitability.
- Use the detailed guides to compare monthly contribution, goal amount, and return-rate scenarios with the same assumptions used by the calculator.
