401(k) Fee Study: 75% of Small Business Plans Pay Hidden Fees

Employers have a fiduciary responsibility to ensure the fees paid by their 401(k) plan are “reasonable” – so excessive fees do not reduce the investment returns of plan participants needlessly. To do that job, employers should ”benchmark” their 401(k) fees periodically by comparing them to industry averages and/or the fees charged by competing 401(k) providers. Sounds straightforward, but this information is hard to find and often harder to compare on an apples-to apples basis.

Fees are difficult to compare for two reasons. First, public information – most notably, the Form 5500 – provides only snippets of 401(k) fee data and is generally not suitable for completing a benchmark comparison. Second, 401(k) providers can charge "hidden” administration fees – in general, revenue sharing and wrap fees – whose dollar amount cannot be found in 408b-2 fee disclosures. In short, “following the money” is a difficult job even for those employers willing to invest the time and energy to do so.

To help employers benchmark their 401(k) fees, Employee Fiduciary launched a fee comparison service a few years ago. When this service is requested, we will total a plan’s “all-in” fee (administration fees + investment expenses) and then compare the amount to a comparable plan with Employee Fiduciary. Since launching our service, we’ve helped hundreds of employers evaluate their 401(k) fees – including all hidden administration fees.

Recently, we recently studied our latest fee comparisons. Below is a summary of the fees we found for 104 small business plans with less than $5 million in assets, including key findings.

Key findings

We made the following observations during our 2021 study: 

  • The 1.18% all-in fee average was quite a bit lower than the 1.40% average we found in our 2018 study, while $445.43 per-capita admin fee average was about the same ($422.30 in 2018). In other words, we found 401(k) investment expenses dropped in recent years, while 401(k) administration fees remained steady. Perhaps due to more investment in low cost index funds.
  • 75.96% of plans paid “hidden” administration fees – in general, revenue sharing and wrap fees.
  • 6 of the top 10 highest-priced 401(k) providers in terms of per capita administration fees also ranked in the top 10 based on their % of hidden fees. 
  • 9 of the top 10 highest-priced 401(k) providers in terms of per capita administration fees were insurance companies. The reason? My guess is their widespread use of variable annuities – which are mutual funds “wrapped” in a thin layer of insurance with additional fees and redemption restrictions – as plan investments. A “wrap” fee can be 1% or more, turning low cost mutual funds into costly variable annuities
  • It’s important to evaluate 401(k) administration fees on a per-capita basis. The reason - many 401(k) providers charge asset-based administration fees that can appear reasonable on all-in fee basis, but anything but on a per capita basis. Consider this plan with $3,091,755 plan with 7 participants. While it’s 1.18% all-in fee was average, it’s $4,405.63 per capita admin fee was almost ten times average!

The Takeaway – Hidden 401(k) Fees Are Usually Higher

According to a recent Pew Charitable Trusts survey, only 19% of small to midsize employers are “very familiar” with the fees paid by their 401(k) plan, while 34% were “not at all familiar.” The remaining 47% said they were only “somewhat familiar.”  The culprit for this confusion? Hidden 401(k) administration fees like revenue sharing and wrap fees. I have no doubt.

And yet, our latest 401(k) fee study found 75% of small business plans pay them. If you use a 401(k) provider with a high percentage of hidden fees, we highly recommend you take a closer look at their 408b-2 fee disclosure to find out what you’re actually paying. There’s a good chance the amount could be a lot lower – which could ultimately help plan participants retire years sooner.New call-to-action
