Why the average is so much higher than the median

The average at 40, $708,400, is 3.9 times the median. A small number of very wealthy households pull it up, so it sits around the 81st percentile: most households at 40 hold less than the average. The median is the better guide to a typical household.

Figures are from the Federal Reserve’s 2025 Survey of Consumer Finances, released October 2026, in 2025 dollars. Each age uses households whose head is within about two years of it, so the line moves smoothly from one age to the next. Net worth is everything owned, including home equity and retirement accounts, minus everything owed. Future Social Security and pension payments are not counted.
