Understanding ETF Fees

4 min

Fees might seem small, but they compound over decades and can cost you tens of thousands of dollars. Understanding expense ratios is critical.

Expense Ratio

The expense ratio is the annual fee charged by the ETF, expressed as a percentage. A 0.10% expense ratio means you pay $10 per year for every $10,000 invested. This fee is automatically deducted from the fund's assets—you never see a bill.

Why Low Fees Matter

Over 30 years, the difference between a 0.04% expense ratio and a 0.75% ratio on a $100,000 investment can exceed $50,000 in lost returns. Lower fees mean more money stays invested and compounds for you.

Other Costs to Consider

Trading commissions: Most brokers now offer commission-free ETF trades. Bid-ask spread: The difference between buying and selling prices; tighter spreads are better. Tax efficiency: ETFs are generally more tax-efficient than mutual funds due to their structure.
