Forgotten 401(k) fees cost workers thousands in retirement savings

With more Americans job hopping in the wake of the Great Resignation, the risk of “forgetting” a 401(k) plan with a previous employer has jumped, recent studies show. 

As of 2023, there were 29.2 million left-behind 401(k) accounts holding roughly $1.65 trillion in assets, up 20% from two years earlier, according to the latest data by Capitalize, a fintech firm.

Nearly half of employees leave money in their old plans during work transitions, according to a 2024 report from Vanguard.

However, that can come at a cost.

For starters, 41% of workers are unaware that they are paying 401(k) fees at all, a 2021 survey by the U.S. Government Accountability Office found.

In most cases, 401(k) fees, which can include administrative service costs and fees for investment management, are relatively low, depending on the plan provider. 

But there could be additional fees on 401(k) accounts left behind from previous jobs that come with an extra bite.

Former employees who don’t take their 401(k) with them could be charged an additional fee to maintain those accounts, according to Romi Savova, CEO of PensionBee, an online retirement provider. “If you leave it with the employer, the employer could force the record keeping costs on to you,” she said.

According to PensionBee’s analysis, a $4.55 monthly nonemployee maintenance fee on top of other costs can add up to nearly $18,000 in lost retirement funds over time. Not only does the monthly fee eat into the principal, but workers also lose the compound growth that would have accumulated on the balance, the study found.

Fees on those forgotten 401(k)s can be particularly devastating for long-term savers, said Gil Baumgarten, founder and CEO of Segment Wealth Management in Houston.

That doesn’t necessarily mean it pays to move your balance, he said.

“There are two sides to every story,” he said. “Lost 401(k)s can be problematic, but rolling into a IRA could come with other costs.”

When workers switch jobs, they may be able to move the funds to a new employer-sponsored plan or roll their old 401(k) funds into an individual retirement account, which many people do.

But IRAs typically have higher investment fees than 401(k)s and those rollovers can also cost workers thousands of dollars over decades, according to another study, by The Pew Charitable Trusts, a nonprofit research organization.

Collectively, workers who roll money into IRAs could pay $45.5 billion in extra fees over a hypothetical retirement period of 25 years, Pew estimated.

Another option is to cash out an old 401(k), which is generally considered the least desirable option because of the hefty tax penalty. Even so, Vanguard found 33% of workers do that.

While leaving your retirement savings in your former employer’s plan is often the simplest option, the risk of losing track of an old plan has been growing.

Now, 25% of all 401(k) plan assets are left behind or forgotten, according to the most recent data from Capitalize, up from 20% two years prior.

However, thanks to “Secure 2.0,” a slew of measures affecting retirement savers, the Department of Labor created the retirement savings lost and found database to help workers find old retirement plans.

“Ultimately, it can’t really be lost,” Baumgarten said. “Every one of these companies has a responsibility to provide statements.” Often simply updating your contact information can help reconnect you with these records, he advised.   

You can also use your Social Security number to track down funds through the National Registry of Unclaimed Retirement Benefits, a private-sector database.

In 2022, a group of large 401(k) plan administrators launched the Portability Services Network.

That consortium works with defined contributor plan rollover specialist Retirement Clearinghouse on auto portability, or the automatic transfer of small-balance 401(k)s. Depending on the plan, employees with up to $7,000 could have their savings automatically transferred into a workplace retirement account with their new employer when they change jobs.

The goal is to consolidate and maintain those retirement savings accounts, rather than cashing them out or risk losing track of them, during employment transitions, according to Mike Shamrell, vice president of thought leadership at Fidelity Investments, the nation’s largest provider of 401(k) plans and a member of the Portability Services Network.
