How it works

The calculator compounds monthly: each month the balance grows by the monthly return, then the contribution is added. A higher assumed return has a large effect over long periods, so test a conservative and an optimistic number.

Returns are not guaranteed; taxes, fees and inflation are not included. This is an estimate, not financial advice.
