The number of retirement savers sitting on a million bucks or more in their 401(k)s, 403(b)s, or IRAs lifted off last year.
The band of 401(k)-created millionaires jumped by 27% in 2024, increasing from 422,000 to 537,000, while the number of IRA-created millionaires bumped up 8% over the year from 318,863 to 344,413, according to a new analysis by Fidelity Investments.
The average 401(k) balance of $131,700 at the end of 2024 ranks as the second-highest average on record for the firm and is an 11% increase from the start of 2024. The average IRA balance was $127,534, up 8% for the year.
Gen X savers had the most bulging balances — average account balances were up 18% from a year ago, $508,000 vs. $589,400. For those Gen Z savers who held their 401(k) for five years, accounts popped to an average of $52,900 — an increase of 66% over the past year.
“Retirement savers experienced positive growth in 2024, which means that the number of individuals who have a million dollars or more in their retirement savings also increased,” Michael Shamrell, vice president of Workplace Thought Leadership at Fidelity Investments, told Yahoo Finance.
The driver: A robust economy, lower inflation, and the Federal Reserve’s interest-rate cuts totalling one percentage point.
The S&P 500 (^GSPC) ended the year with a gain of 23%. The Dow Jones Industrial Average (^DJI) jumped nearly 13%, and the Nasdaq (^IXIC) ballooned close to 29%.
Here’s how 401(k)-created millionaires break down by generation: More than 4 in 10 are boomers: 41%, Gen X: 57%, and millennials: 2%. “Boomers have already started drawing from their retirement savings, which is why the number is lower than Gen X at this point,” Shamrell said.

One thing of note: “More millennial savers than ever before are now using Roth 401(k)s, removing the burden that taxes could pose on their savings when they enter retirement and begin to draw from their nest egg,” Shamrell said. “The millennial generation is making smart investment decisions now that they know will benefit them even further 20 or 30 years down the road when they ultimately enter retirement.”
Fidelity’s analysis covers more than 50 million IRA, 401(k), and 403(b) retirement accounts.
Retirement saving is a long-term game.
“The important thing to keep in mind when it comes to 401(k)-created millionaires is that these individuals have been saving for a long time,” Shamrell said. “The average 401(k)-created millionaire has been in their plan for 26 years and has an average contribution rate of almost 18%.”
