Frequently asked questions

A conservative estimate after fees. Try several values to see how sensitive the result is.

Working backwards from a goal

Instead of asking what your savings will become, this calculator asks how much you need to save. It assumes monthly contributions and monthly compounding at the annual return you enter, and subtracts what your starting balance will grow into.

Returns are never guaranteed, and inflation, taxes and fees reduce real growth. Test a few conservative return rates to see a realistic range. This is not investment advice.
