For 25 years, Vanguard has been keeping score on the great American retirement experiment. Every year, it publishes the most comprehensive snapshot in the industry of how workers save, how much they accumulate, and whether any of it will be enough. The 2026 edition is out. Spoiler: It depends on which number you’re looking at.
The number Vanguard leads with is $167,970—the average 401(k) balance across nearly 5 million accounts the firm administered at year-end 2025. That’s a record high, up 13% from the year before—carried there on the back of a stock market that had a very good year.
