How it works

This calculator projects a future balance by combining your starting amount, regular contributions, return rate, and compounding frequency. It is useful for comparing how much of the final balance comes from your own deposits versus investment growth.

Examples

$10,000 plus $200 per month for 10 years at 7%: the future value is driven by both contributions and compounding. Longer time horizons magnify the share of the balance coming from investment gains rather than new cash.

Methodology & assumptions

  • Uses a constant assumed return rate.
  • Contributions are treated as regular periodic deposits.
  • Fee, tax, and inflation inputs are scenario adjustments only.
  • Actual market returns will vary year to year.
