- Set expected return and inflation.
- Enter the yearly income you want in retirement (in today’s money).

What return should I assume?
Long-run diversified portfolios have historically returned roughly 5–8% a year before inflation, but returns are not guaranteed. Test a range to see how sensitive your plan is.
What is the 4% rule?
A rule of thumb that withdrawing 4% of your starting balance each year (adjusted for inflation) has historically lasted around 30 years. This calculator uses a more direct year-by-year projection instead.
