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 $5,000 a month 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) |
|---|---|---|---|
| 18 years | $1,321,754 | $1,980,806 | $3,058,743 |
| 35 years | $4,215,602 | $7,743,080 | $14,810,780 |
The middle of the simulation sits below the steady 7% figure of $8,557,068 because ups and downs cost compounding: a 20% loss needs a 25% gain to get back.
What $8,557,068 would pay in retirement
At a 4% first-year withdrawal, $8,557,068 pays about $342,283 a year, $28,524 a month, before tax; in today’s dollars that is about $121,642 a year. How long a balance near it lasts at each withdrawal: how long $5 million lasts. To stop saving early and let growth do the rest, see Coast FIRE numbers by age.
$60,000 a year is more than the 2026 401(k) limit of $24,500, so part of it would go to a taxable account or a spouse’s plan. See contribution limits, the 401(k) calculator and the Roth IRA calculator.

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.
