Compound interest is the process where your money grows by earning interest on both your original investment and the interest accumulated over time, creating exponential growth rather than a simple linear increase.
This calculator helps you understand that growth by allowing you to enter your principal amount, interest rate, time period, compounding frequency, and any additional contributions to instantly see your future value, total interest earned, and overall savings progress. Compounding frequency—whether yearly, monthly, or daily—affects how quickly your balance grows, with more frequent compounding adding interest more often. Adding extra contributions can accelerate your results even further, as each deposit begins earning interest immediately.
The calculator uses the standard compound interest formula to ensure accurate projections and provides a clear breakdown of your final amount, contributions, and interest earned. While it offers a reliable estimate of long‑term growth, it does not factor in taxes, inflation, or market fluctuations, so actual results may vary.
