How it is worked out

The steady-return figures are the how-long calculator’s own math: the withdrawal comes out at the start of each year, the rest earns the return, and the next withdrawal is 2% larger to keep up with inflation. Real markets do not return the same every year, so the odds come from 1,000 simulated sequences of yearly returns: Trinity-style (7% average, 12% volatility, 3% inflation) and cautious (5%, 15%, 2%). Taxes and fees are not taken out; take them from the withdrawal you enter. More on the method on the methodology page.
