Expense Ratio
The expense ratio is the annual fee charged by a mutual fund, expressed as a percentage of the assets it manages.
Start the lessonIntroduction
A small fee can have a big impact
The expense ratio is the annual cost that a mutual fund charges for managing the portfolio. It is usually shown as a percentage such as 0.50%, 1.00%, or 2.00% per year.
Even though the percentage looks small, it matters because mutual fund returns are compounded over many years. A fund with a lower expense ratio can leave more money in the investor's hands over time.
Why it matters
Costs quietly reduce returns
Annual cost
The expense ratio is charged every year for managing and operating the fund.
Compounding effect
Higher fees reduce long-term wealth creation, even if the percentage feels small.
Comparison value
Investors should compare similar funds before choosing one.

This example uses a simple net return of annual return minus expense ratio.
Simple takeaway
A 1% difference in fees may look small, but over time it can materially reduce wealth creation.
Common mistakes
What beginners often get wrong
- • Looking only at past returns and ignoring the expense ratio.
- • Assuming all funds with similar goals are equivalent in cost.
- • Paying very high fees without checking whether the strategy is worth it.
- • Forgetting that even small fees compound over time.
