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 $1 million ended up: 1 in 10 markets finished below the first figure, half below the middle one, and 1 in 10 above the last.

40 years$4,554,801$11,692,445$29,533,928

The middle of the simulation sits below the steady 7% figure of $14,974,458 because ups and downs cost compounding: a 20% loss needs a 25% gain to get back.

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.
