The expense ratio is the annual fee you pay a fund to manage your investment, expressed as a percentage. Lower is generally better, especially for long-term growth. Always compare expense ratios before investing in mutual funds or ETFs to avoid unnecessary costs that eat into your returns.
In simple terms, the expense ratio tells you how much a fund charges annually to manage your money. For example, if a fund has a 0.50% expense ratio, you’re paying $5 per year for every $1,000 you’ve invested.
How Is Expense Ratio Calculated?
The expense ratio is calculated using this formula:
Expense Ratio (%) = (Total Annual Fund Operating Expenses / Total Assets Under Management) × 100
It includes:
- Management fees
- Administrative costs
- Marketing and distribution (also known as 12b-1 fees)
- Other operational costs
Note: It does not include brokerage fees or trading costs.
Real-World Example
Let’s say you invest $10,000 in two funds:
- Fund A: Expense ratio of 0.10%
- Fund B: Expense ratio of 1.00%
Assuming both funds grow 8% annually for 20 years:
- Fund A final value: ~$45,857
- Fund B final value: ~$40,866
You lose nearly $5,000 just because of higher fees!

FAQs
Q: What is a good expense ratio?
A: For index ETFs, anything below 0.20% is generally considered good. Actively managed funds may be higher.
Q: Does the expense ratio get deducted automatically?
A: Yes. It’s taken out of your fund’s returns before you see them, so you don’t need to pay it manually.
Q: Is a 1% expense ratio too high?
A: For index funds, yes. For actively managed funds, it’s common, but you should evaluate if the performance justifies it.
