Why a 0.13% difference is not small
Fee drag compounds against you in exactly the way returns compound for you. Each year the fee is deducted, and every euro deducted also forfeits all the growth it would have generated over the remaining decades.
Broad European UCITS index ETFs are widely available between roughly 0.07% and 0.22% TER. Over a thirty-year horizon, the gap between the cheap end and the expensive end of that range typically costs several percent of final portfolio value — for two funds tracking the same index, holding the same companies, in the same proportions.
What to check besides the headline TER
TER is the advertised number, not the total cost. Tracking difference — how far the fund actually lagged its index — captures the real result and is sometimes better than TER alone would suggest, because securities lending and efficient withholding-tax treatment can offset part of the fee.
Fund domicile matters as much as fees for European investors. Ireland-domiciled UCITS ETFs benefit from a favourable treaty rate on US dividend withholding tax, which for a US-heavy portfolio can outweigh a small TER advantage elsewhere. Compare total cost of ownership, not the marketing figure.
Common questions
What is ETF fee drag?
Fee drag is the compounding cost of an ETF total expense ratio. Because the fee is charged on the whole balance every year, a seemingly small TER can consume a large share of final wealth over decades.
Is a 0.20% TER expensive?
Broad European UCITS index ETFs are widely available between 0.07% and 0.22% TER. Over a 30-year horizon the difference between 0.07% and 0.20% typically costs several percent of final portfolio value.
