What Is Expense Ratio?
The yearly fee a fund charges, shown as a percentage of the money you have invested in it.
If a fund has a 0.50% expense ratio, you pay $5 a year for every $1,000 invested — taken automatically, so you never see a bill. It sounds tiny, but because it is charged every year on your whole balance, it quietly compounds against you.
Over decades, the gap between a 0.03% fund and a 1% fund can cost you tens of thousands of dollars. This is why low-cost index funds and ETFs are so often recommended: the fee is one of the few variables you fully control.
Two identical funds, one charging 0.05% and one charging 1%. Same returns, but after 30 years the cheap one can leave you with a noticeably bigger balance — purely on fees avoided.
Key points
- A yearly fee, deducted automatically from the fund.
