What is a Investment Compounding Calculator?

This investment compounding calculator illustrates how an initial balance, recurring contributions and an assumed return could grow over time. The output is hypothetical and does not predict future market performance.

Formula

Future value applies periodic growth plus recurring contributions

Example calculation

A $10,000 starting balance with $200 monthly contributions and a hypothetical 7% annual return can be projected over a selected number of years.

How to use this tool responsibly

  • Use conservative assumptions.
  • Compare multiple return scenarios.
  • Remember returns are not steady in real markets.
