Your 401(k) fees were reasonable once. Who’s checking now?

Your 401(k) provider’s fee disclosures are the clearest picture you’ll get of what your plan costs. They’re also dense, technical, and written for compliance rather than for the person who has to make sense of them.

As someone who oversees your company’s plan, you’re responsible for making sure the compensation it pays is reasonable. That applies not just on the day you signed the contract, but for as long as you keep paying it.

Reasonable isn’t a one-time test

There’s no single number that makes a fee “reasonable.” It depends on what size your plan is, what services you receive, and what the market charges for similar plans today, and all three change over time.

Here’s a simple, hypothetical example of how that plays out:

Nothing about the fee schedule changed, and the plan is paying twice as much for the same services. That isn’t necessarily a problem, but it’s a question worth asking.

Growth can also work in your favor. Larger plans may qualify for lower-cost share classes or pricing tiers that weren’t available at the start. That doesn't always happen on its own, so someone may need to ask. Plans that haven't benchmarked their fees in a while may find that what they pay no longer matches what similar plans pay.

Three questions you can answer in 20 minutes

You don’t need to be a retirement specialist to take an informed look at your own plan. Start by pulling three things: your most recent provider fee disclosure (often called the 408(b)(2) disclosure), a summary of your plan features (match, vesting, eligibility), and your current participation numbers. Then look for:

1. How is each provider paid? Look for the difference between fees charged directly and fees built into the investments (sometimes called indirect compensation or revenue sharing). Plans often pay both.
2. What exactly do you get for it? List the services: recordkeeping, advice, enrollment support, compliance help, participant education. Fees only mean something next to services.
3. What happens to the fee as your plan grows? If the cost rises automatically with assets but the services stay the same, that’s the gap worth examining.

What a proper benchmark should look like

Benchmarking compares your plan against similar plans. It can be as formal as a request for proposals, or as simple as gathering a few proposals or independent data. A good one looks at more than price:

• Cost: total dollars and percentage of assets, and how the structure changes as assets grow
• Services: what’s included, and what’s missing
• Plan design: your match and contribution levels, vesting rules, and participation rate, compared with similar employers
• Investments: whether the menu fits your workforce, and whether lower-cost options are available
• Service quality: how responsive your provider’s team is, and how participants experience the support

Cheaper isn’t automatically better. Sometimes a higher fee buys better service, and a good benchmark tells you which it is.

For many employees, the 401(k) is part of how they judge an employer, so a plan that lags behind similar companies has implications that can affect hiring and retention.

What to do with the results

A benchmark usually leads to one of three outcomes:

1. Your plan holds up. You keep your provider with confidence, and you have a documented review on file.
2. Something is out of line. The results give you leverage for a conversation with your current provider about pricing or services.
3. The gap is large. A full search for a new provider may be worth the effort.

All three are good outcomes, because in each one you know where you stand. The documentation is part of the benefit, since a recorded review is part of showing a prudent process.

Fees tell you what you pay, but they won’t tell you what you get between annual meetings. The most useful question to ask about your plan may be who’s paying attention to it the rest of the year. Fee reviews should happen on a regular schedule that your plan committee sets and documents. If you only hear from your advisor once a year, it is fair to ask what oversight happens in between.

A fee is easier to judge when you know what it covers. Fees, services, and attention are one question, and the plans that stay in good shape are the ones where someone keeps asking it.
