A steady return is the kindest possible assumption. Real portfolios move unevenly, and a bad market in the first years of withdrawals does more damage than the same loss later. Test a lower return before trusting the result.

How long will the money last?
The withdrawal rate, the first year’s withdrawal as a share of the portfolio, is the single biggest factor in how long savings last.
How the calculation works
Each year: balance = balance × (1 + return) − withdrawal, then the withdrawal rises by inflation.
A $900,000 portfolio with a $40,000 first-year withdrawal is a 4.4% withdrawal rate. At a 5% return and 2.5% inflation, about $330,700 is left after 30 years and the money lasts about 35 years. By year 30 the withdrawal has grown to about $81,856.
The limit of a steady return
Real returns vary, and losses early in retirement do more damage than the same losses later. This is sequence-of-returns risk. Test a lower return, and count Social Security and pensions, which reduce how much the portfolio has to supply.
