ETF fees are lower than mutual fund fees for one simple reason: exchange traded funds skip most of the costs mutual funds pass along to shareholders. In 2024, the average expense ratio for an index equity ETF sat at 0.14 percent, versus 0.40 percent for the average equity mutual fund.
At a Glance
- Mutual fund companies have been cutting fees for years just to stay competitive with cheap ETFs.
- ETFs skip the 12b-1 marketing fees that many mutual funds charge.
- An expense ratio bundles management fees, operating costs, and marketing charges into one percentage of assets.
- Mutual funds can carry load fees, account fees, and redemption penalties that ETFs generally avoid.
- ETFs use a share creation process that keeps trading costs and capital gains distributions low.
What Actually Shows Up on a Mutual Fund Bill
Every mutual fund prospectus discloses an expense ratio, and that number tells you what the fund actually costs to own. It wraps together management fees paid to whoever runs the portfolio, 12b-1 fees that cover marketing and sometimes staff bonuses (capped at 1 percent of assets), plus any account fees for small balances, redemption fees aimed at short term traders, exchange fees for moving between funds at the same company, and purchase fees charged when you buy in.
Then there is the load fee, a separate charge paid to the broker or agent who sold you the shares. It is typically 5 percent of what you invest, though the legal ceiling is 8.5 percent. Plenty of no load funds exist specifically so investors can dodge this one time hit.
Why ETFs Run Leaner
ETF costs never show up as a separate withdrawal on your account statement. Instead they get deducted daily from the fund's net asset value, quietly and continuously. Because most ETFs are passively managed and structured as no load products, there is no purchase fee to begin with, and many online brokers now offer commission free ETF trades on top of that.
ETFs also skip the annual 12b-1 fee entirely. That fee exists in the mutual fund world to cover the cost of attracting new shareholders, and current investors foot the bill for it. ETFs simply do not pass that marketing expense along.
Active Versus Passive: Why It Matters for Cost
An actively managed fund employs a manager or team constantly buying and selling in an attempt to beat a benchmark index. That hands on approach costs money, and shareholders cover it through higher fees. A passively managed fund just tracks an index, buying and selling only when the index itself changes composition. Less activity means fewer expenses, which is a big part of why so many ETFs, built as passive vehicles, land on the cheaper end of the fee spectrum.
How Capital Gains Quietly Raise Mutual Fund Costs
When a mutual fund investor cashes out, the fund often has to sell underlying assets to cover that redemption. Those sales can trigger a capital gains distribution spread across every shareholder, not just the one who sold. That means you could owe income tax on gains even if you never sold a single share, and the fund company's added transaction work raises its operating expenses too. ETFs largely sidestep this because selling ETF shares on the open market does not force the fund to liquidate anything.
The Mechanism Behind Lower ETF Costs: In Kind Redemption
ETFs rely on a creation and redemption process built around swapping baskets of stock for baskets of ETF shares, rather than cash transactions. An investor or authorized participant can trade a basket of underlying stocks for an equivalent chunk of ETF shares, or redeem ETF shares for that same basket, instead of the fund buying or selling securities on the open market. That in kind swap cuts down on paperwork, trading costs, and the tax events that come from asset sales, which is a major reason ETF expense ratios tend to run lower than mutual fund ones.
It is also worth noting that the ETF landscape expanded significantly in 2024, when the SEC approved eleven spot bitcoin ETFs to trade on NYSE Arca, Cboe BZX, and Nasdaq in January, followed by approval for spot ether ETFs in May, which began trading in July 2024. These newer products broadened what ETF investors can access, even as the underlying cost advantages of the ETF structure stayed the same.
Will Mutual Fund Fees Keep Falling?
Mutual fund companies have already trimmed fees for years to keep pace with cheap ETFs, and that pressure shows no sign of letting up. Whether traditional fund managers can close the gap without abandoning active management, or whether investors keep migrating toward passive, no load ETF structures instead, remains the question shaping the fee wars ahead.
