How this calculator works

This tool estimates how your savings could grow if you start with an initial amount, add the same amount every month, and (optionally) earn interest along the way. It assumes interest compounds monthly — meaning each month's interest is calculated on your current balance, including any interest you've already earned. That's how most savings accounts actually work.

If you're not sure what interest rate to use, leave it at a low number like 0% to see your progress from contributions alone, or check out What Is a High-Yield Savings Account? to understand realistic ranges.

A few honest limitations

  • This is a projection, not a guarantee. Real interest rates change over time, and this calculator assumes a fixed rate for the whole period.
  • It doesn't account for taxes on interest earned, which may apply depending on your situation.
  • It assumes your monthly contribution stays exactly the same every month, which is a simplification — real life is rarely that consistent, and that's okay.
