How to Use

Enter an initial lump sum, regular monthly contribution, expected annual return, and investment horizon to project your index fund portfolio value. Global index funds tracking the MSCI World or S&P 500 have historically returned around 7–10% per year after inflation over long periods. This calculator does not account for fund charges — a 0.1–0.2% annual charge on a low-cost index fund has a negligible impact over most horizons.
