Fees Are Not the Whole Story

By Walid Mograbi · 2026-06-14 · 2 min read

Before judging an ETF by its fee percentage, evaluate the real cost by combining all deductions that reduce return, not just the annual expense ratio.

The lesson in one sentence

An ETF is not cheap or expensive based on a single number. Look at what is truly deducted from your return.

What the annual expense ratio is (and isn’t)

• The annual expense ratio is a recurring fund cost.
• It appears as one part of the expense picture.
• It does not represent all the money you may lose in a real trade.

Add the trading layer to your calculation

• You may pay a broker commission on buy and sell.
• The bid-ask spread can consume value even when the fee rate is low.
• Liquidity and order size affect how noticeable these costs are.

Accurate comparison starts with a checklist

• [ ] Read the fund’s annual expense ratio.
• [ ] Check commission terms for buying and selling.
• [ ] Verify order execution cost conditions.
• [ ] Compare what is deducted from returns, not only headline percentages.

The right comparison metric

Use the total impact on return, not a single label. A practical rule: **net deduction = return impact from fees + commissions + spread effects**.

Core warning

**Low fees do not always mean low trading cost.** A fund with a small expense ratio can still be expensive to trade.
