How It Works

The Investment Calculator uses the compound interest formula to estimate the future value of an investment. The formula takes into account the starting amount, return rate, investment length, and additional contributions.

Formula Used

End Balance = Starting Amount × (1 + Return Rate)^{Investment Length} + Additional Contribution × [(1 + Return Rate)^{Investment Length} - 1] / Return Rate
