57% of the final value comes from growth rather than from money you paid in.

Growth overtakes the money you paid in during year 17.

Results are illustrative estimates based on the numbers you enter. Actual investment returns, lender calculations, fees and repayment schedules may differ. Compoundly is not investment, lending, tax or debt advice.

Solving for a target

Future value is linear in both the contribution and the starting amount, so those two are solved exactly rather than by searching. Time and return are solved numerically, and time is reported as the first whole month that clears the target — no real compounding period ends halfway through a month.

When you solve for a required return, Compoundly says plainly that the answer is the return the arithmetic demands, not a prediction that such a return is available. Higher assumed returns generally come with a higher risk of loss.
