What Fees Are You Actually Paying in Your 401(k)

The Fees Nobody Talks About

Every 401(k) charges fees. Most people have no idea how much they are paying because the fees are not deducted as a visible line item on a statement. Instead, they are quietly taken out of your investment returns before you ever see them. You do not get a bill. You do not get a notification. The money just grows a little slower than it would otherwise, and the difference compounds over decades.

A 2023 study by the Investment Company Institute found that the average total plan cost for 401(k) participants was around 0.85% of assets per year. On a $100,000 balance, that is $850 per year -- not taken from your paycheck, but shaved off your returns. On a $300,000 balance, it is $2,550 per year. Over a 30-year career, the difference between a low-fee plan and a high-fee plan can amount to tens of thousands of dollars.

The Three Layers of 401(k) Fees

Investment fees (expense ratios). Every fund in your 401(k) has an expense ratio -- an annual percentage that covers the cost of managing the fund. Index funds typically charge 0.03% to 0.20%. Actively managed funds often charge 0.50% to 1.00% or more. These fees are baked into the fund's performance. If a fund earns 8% before fees and has a 0.75% expense ratio, your actual return is 7.25%. You will find expense ratios in the fund fact sheets or prospectuses available through your plan.

Plan administration fees. Someone has to run the 401(k) plan -- process contributions, send statements, maintain the website, handle compliance. Those costs are either paid by your employer, passed on to participants, or split between both. When passed to participants, they might show up as a flat dollar amount per quarter (like $10-$25) or as a percentage of your balance. These fees are typically disclosed in the plan's annual fee disclosure notice, which your employer is required to provide.

Individual service fees. These are charged for specific actions like taking a loan from your 401(k), making a hardship withdrawal, or processing a rollover. They are less common in day-to-day investing but can add up if you use these features. They are usually listed in the plan's fee schedule.

How to Find Out What You Are Paying

Your employer is legally required to give you a fee disclosure document at least once a year (often called a 404(a)(5) notice, though it will not say that on the document itself). It will list the investment options in your plan along with their expense ratios, any plan-level fees, and how those fees are charged. If you have never read this document, it is worth digging it out of your email or requesting a copy from HR.

You can also look at your 401(k) statement. Some plans now include a line item showing total fees deducted for the quarter or year. If yours does not, the fund fact sheets on your plan's website will show each fund's expense ratio.

What You Can Do About High Fees

You cannot negotiate 401(k) fees directly -- they are set by your employer and the plan provider. But you can choose the lowest-cost investment options within your plan. If your plan offers both an S&P 500 index fund at 0.05% and an actively managed large-cap fund at 0.85%, the math over time heavily favors the lower-cost option, assuming similar market exposure.

If your plan only offers high-cost options, it is still generally worth participating at least enough to get the full employer match -- the match is free money that typically outweighs even high fees. Beyond the match, if your plan's fees are significantly above average, contributing to a traditional or Roth IRA (where you choose your own investments and control costs) is an option worth considering for additional retirement savings.
