Expense ratios represent the annual cost of owning a fund, expressed as a percentage of assets. These fees are deducted automatically from fund returns — you never receive a bill, but they directly reduce your investment growth.

Costs by Fund Type
Expense ratios vary dramatically by management style and asset class. Actively managed funds charge more to cover research staff and trading costs, though most fail to overcome this fee headwind over time.
Active Fund Expense Ratios by Category

|---|---|---|---|
| US Large Cap Equity | 0.60% | 0.25–0.40% | 1.00–1.50% |

401(k) Plan Fund Averages (2024)
| Fund Type | 401(k) Avg. | Industry Avg. | Note |
|---|---|---|---|
| Equity Funds | 0.26% | 0.40% | 35% below retail |
| Target Date Funds | 0.29% | 0.40% | Down 57% since 2008 |
| Bond Funds | 0.27% | 0.38% | 29% below retail |
401(k) advantage: Employer-sponsored plans often negotiate institutional share classes with lower expense ratios than retail investors can access individually.
Long-Term Fee Impact
Small differences in expense ratios compound dramatically over time. A 1% annual fee difference can cost roughly 25% of final portfolio value over a 30-year investing career.

Frequently Asked Questions
What is a good expense ratio?
For passive index ETFs and mutual funds, 0.20% or below is good; 0.10% or below is excellent. For actively managed funds, 0.50%–0.75% is reasonable given the added research costs. Any fund charging above 1.00% needs to justify that cost with consistently strong after-fee performance — which roughly 90% of active funds fail to deliver over 15-year periods (SPIVA data).
What is the average expense ratio for index funds?
The asset-weighted average for passive index funds is 0.11% as of 2024, down from 0.27% in 2005, according to Morningstar. S&P 500 index ETFs like VOO and VTI now commonly charge as little as 0.03%, while some Fidelity index funds (FXAIX, FSKAX) charge 0.015%. The overall industry average across all fund types is 0.34%.
What is a good 401(k) expense ratio?
401(k) plans typically negotiate institutional share classes, so their averages run below retail rates. The 2024 average for 401(k) equity funds is 0.26% — about 35% below the retail average of 0.40%. For a 401(k), any equity fund under 0.30% is solid; target-date funds under 0.40% are competitive. Compare your plan's fund lineup using the fee disclosures your plan administrator is required to provide.
How much does a 1% expense ratio cost over 30 years?
On a $10,000 investment earning 7% gross annually, a 1.00% expense ratio leaves you with $57,430 after 30 years — compared to $75,400 with a 0.03% ETF. That is $18,190 lost to fees, a 24% reduction in final portfolio value. A 1.50% expense ratio reduces the final balance further to $50,030, costing $25,600 in foregone growth.
What is not included in the expense ratio?
The expense ratio does not cover: sales loads (front-end charges up to 5.75% or back-end charges up to 5.00%), trading commissions on the fund's own buy/sell activity, account maintenance fees charged by the broker, bid-ask spreads when buying or selling ETF shares, or taxes on capital gains distributions. These are separate costs that add to the total cost of ownership beyond the headline expense ratio figure.
What expense ratio is too high?
For passive index funds, anything above 0.25% is hard to justify given the availability of S&P 500 ETFs at 0.03%–0.10%. For actively managed funds, above 1.00% is a red flag — and above 1.50% is rarely worth it. The key question is always whether the net-of-fee performance consistently justifies the premium over a low-cost index alternative.
