How This Calculator Works
This calculator uses the future value of an annuity formula, compounded monthly. It assumes your monthly contribution is made at the beginning of each month and your initial lump sum earns interest from day one.
The default 10% return reflects the historical long-term average of the S&P 500 before inflation. Past performance does not guarantee future results — this is for planning purposes only.
