More Americans are now 401(k) millionaires

More folks can retire as millionaires.

The number of people with $1 million or more saved in their 401(k) accounts leapt 10% from April to the end of June, according to Fidelity Investments. There was also a 13% pop in millionaires with IRA accounts held at the firm during that same timeframe.

And it isn’t just newly minted millionaires who have something to crow about. For the third straight quarter, Fidelity reported retirement account balances increased for all savers. That’s according to the company’s second quarter analysis of savings account balances for more than 45 million IRA, 401(k), and 403(b) retirement accounts.

Numerous factors played a role in the gains, including the ability to stick to saving for the long haul to ensure security in their golden years.

"Overall, the increase in balances [for all investors] was based on ongoing employer and employee contributions, along with positive market performance," Michael Shamrell, vice president for workplace thought leadership for Fidelity, told Yahoo Finance.

"The increase we are seeing in 401(k) millionaires this quarter [also] shows the value of long-term investing."

For the first half of the year, the number of folks hitting that cool million target soared roughly 20%.

All told, there were 378,000 retirement savers in Fidelity 401(k) plans spotting balances of seven figures and beyond as of June 30, up from 340,000 at the end of March and 299,000 at the end of December. There were 350,000 IRA millionaires on June 30, up from 307,623 at the end of March and 280,320 at the end of December.

Still, those tallies fall short of their peaks, which was 442,000 for 401(k) millionaires at the end of 2021 and 376,100 for IRA millionaires in the same quarter when the S&P 500 just finished a nearly 27% 12-month run.

Overall, all retirement savers made out better.

The average 401(k) account balance was $112,400 on June 30, up from $103,900 at the end of December. The average IRA balance was $113,800, up from $104,000 at the end of last year. Boomers, in fact, now have an average balance of just under half a million dollars ($499,700), Fidelity reported.

The bigger balances came from a combination of a few factors.

First, a stronger stock market – the S&P 500 (^GSPC) was up over 15% from January through the end of June. That helped, but account performance wasn’t quite on par with those robust market gains because many of the Fidelity accounts are invested in target date funds that aren't designed to match or exceed the returns of the stock market. Instead, they are meant to provide steady gains through a mix of stock and bond investments until the targeted date of retirement.
