The range in 1,000 simulated markets
A 7% average does not arrive as 7% every year. In 1,000 simulated sequences of returns averaging 7% with 12% volatility, this is where $500,000 ended up: 1 in 10 markets finished below the first figure, half below the middle one, and 1 in 10 above the last.
| After | Weak (1 in 10 lower) | Middle | Strong (1 in 10 higher) |
|---|---|---|---|
| 20 years | $869,826 | $1,668,701 | $3,208,917 |
| 40 years | $2,277,400 | $5,846,222 | $14,766,964 |
The middle of the simulation sits below the steady 7% figure of $7,487,229 because ups and downs cost compounding: a 20% loss needs a 25% gain to get back.
What $7,487,229 would pay in retirement
At a 4% first-year withdrawal, $7,487,229 pays about $299,489 a year, $24,957 a month, before tax; in today’s dollars that is about $91,810 a year.

How it is worked out
Monthly amounts are deposited at the end of each month and compounded monthly at the rate that equals the annual return; lump sums compound once a year. The headline return is 7% a year, the Trinity-style average the site’s retirement pages use; stock-heavy portfolios have averaged more over long periods and bond-heavy ones less, which is why every page shows 4% to 10%. Today’s dollars divide by 3% inflation a year. The range comes from 1,000 simulated sequences of yearly returns averaging 7% with 12% volatility, with each year’s deposits added through the year. Fees and taxes are not taken out. More on the methodology page.
