ETF fees: TER and hidden costs
ETFs are cheap – but not free. Know these costs.
1. TER – the ongoing fund fee
The Total Expense Ratio is the key figure: the ETF’s yearly management cost in percent. It is deducted automatically from the fund – no separate bill.
Typical values:
- Broad index ETFs (S&P 500, MSCI World): 0.05–0.25 %
- Specialty/thematic ETFs: 0.3–0.7 %
Every ETF page shows the TER in the key facts.
2. Tracking difference – the real cost
The TER is only the expected fee. The tracking difference shows how far the actual ETF return deviates from the index – the most honest cost measure, though harder to find.
3. Trading costs
- Order fee: what the broker charges per trade. Many neobrokers: 0–1 €, savings plans often free.
- Spread: the gap between buy and sell price. Tiny for large liquid ETFs.
Why small percentages grow huge
Over long horizons, compounding magnifies costs too. For 200 €/month over 30 years at 7 %, the difference between a 0.20 % and a 0.70 % TER adds up to several thousand euros. Try it in the savings plan calculator .
Bottom line
Prioritise broad diversification first, then low cost. Between two equivalent ETFs, the fee measurably matters over decades.
