An ETF expense ratio is a yearly operating cost shown as a percentage of the fund’s average assets. A 0.20% expense ratio is about $20 a year for each $10,000 invested, though the exact dollar cost changes as the balance changes.
What it means
Running an exchange-traded fund, or ETF, costs money. The fund may pay for management, records, legal work, accounting, and other operations. These costs come from fund assets, which lowers the return investors keep.
You usually do not see the expense ratio leave as one charge. It is built into the fund’s daily value. Find it in the standardized fee table near the front of the prospectus.
The expense ratio does not necessarily include every cost. A brokerage commission, bid-ask spread, adviser fee, or account charge can sit outside it.
A simple example
A 0.05% expense ratio is about $5 a year on $10,000. A 0.50% ratio is about $50. A 1.00% ratio is about $100. Move the decimal two places to turn a percentage into a decimal, then multiply by the balance.
If two ETFs do the same job, the lower cost has a head start. The higher-cost fund must make up the fee difference before it can leave you with the same return.
What people often miss
The dollar amount changes with the fund balance. A rising balance means a larger dollar fee even when the percentage stays the same.
Cost matters, but it is not the only test. A cheap fund that owns the wrong assets for your goal is not a bargain.
Three questions worth asking
- What is the expense ratio in dollars on my balance?
- What other costs sit outside it?
- Does a lower-cost ETF do the same job?
Quick answers
Is an ETF expense ratio charged every year?
Yes. It is an annual operating expense, but it is reflected in the fund’s value over time rather than sent as one yearly bill.
What is a good ETF expense ratio?
There is no single good number for every fund. Compare similar funds doing the same job, then ask what benefit you receive for any extra cost.
