Quick Read
-
Private equity in 401(k) plans charges 2-3% annually in fees, creating a 2-percentage-point drag versus 0.03% index funds that compounds over decades.
-
A PE allocation must outperform low-cost index options by 200 basis points yearly just to break even after fees, a hurdle rising as Treasury yields near 4.5%.
-
Retail-access PE products historically underperform institutional versions by amounts that erase the illiquidity premium, making fee scrutiny essential before 401(k) enrollment.

Kiplinger recently laid out how private equity could land inside everyday 401(k) menus. The fee math deserves scrutiny. Private equity funds typically charge 1.5% to 2% in management fees plus 20% of profits. Stack that on top of recordkeeping and administrative costs already embedded in a workplace plan and the participant ends up paying 2% to 3% annually before a single dollar of outperformance shows up.
The Data In Depth
The comparison set in a 401(k) is brutal. A broad-market index fund inside most plans runs around 0.03% in expenses. The structural fee gap between a private equity sleeve and a vanilla index option is roughly 2 percentage points a year, compounded for the entire working life of the account.

Apply that to a $500,000 balance over 20 years. At a 0.03% expense ratio, fees are a rounding error on the annual statement. At 2%, the same balance surrenders thousands of dollars every year off the top, and the lost capital never compounds. Over two decades, the drag reshapes the ending balance.
The Context The Report Does Not Provide
The hurdle private equity needs to clear is rising. The 10-year Treasury yield sits at 4.46% as of May 13, 2026, and the fed funds upper bound has held at 3.75% since mid-December 2025. A risk-free instrument is paying nearly the all-in fee load of a PE sleeve. To justify the structure, a PE fund must clear the Treasury yield, beat the index, and earn back the 2% to 3% fee stack before the investor sees any edge.
The smoothing argument PE proponents lean on weakens on inspection. The VIX spiked to 31.05 on March 27, 2026 and stayed above 20 for 38 trading days before settling back to 17.87 on May 13. PE valuations would have looked steadier through that window. The fees, however, accrued the entire time, whether the smoothing reflected real insulation or just delayed mark-downs.
Academic work on PE performance persistence adds another wrinkle: retail-access PE products have historically lagged institutional vintages, often by enough to erase the illiquidity premium that justifies the asset class.
