How much do ETF fees cost over time?

A seemingly small fee difference compounds dramatically. On a $50,000 investment growing at 8% over 30 years with $500/month additions: a 0.07% MER (like VAS) costs about $15,000 in fees. A 1.8% MER active fund costs about $330,000. That's $315,000 difference from just 1.73% in fees.

What is a good MER for an ETF?

Australian index ETFs like VAS, A200, and IOZ have MERs of 0.04-0.10%. Diversified ETFs like VDHG are around 0.27%. Anything under 0.30% is considered low-cost. Active managed funds typically charge 0.80-1.80%, which is hard to justify when most underperform the index.

Why a 1% fee is not a 1% problem

Fund fees are quoted as a small annual percentage — the management expense ratio (MER) — charged on your whole balance, every year, whether the fund gains or loses. The reason a fraction of a percent matters is compounding: the fee is deducted from the balance that would otherwise have compounded, so you lose the fee and all the future growth that money would have produced.

A worked example

Invest $100,000 for 30 years at a 7% gross return. At a 0.10% MER (typical of a broad index ETF) you finish with roughly $740,000. At 1.00% — still ordinary for an actively managed fund — you finish with about $574,000. That 0.9% difference costs roughly $166,000, or more than 22% of the final balance, without a single dollar of it appearing as a "charge" you ever consciously paid.

The fees that don't appear in the MER

The headline ratio isn't the whole cost. Add brokerage on each buy and sell, the bid-ask spread you cross when trading (wider on thinly traded ETFs), and for some funds a performance fee or transaction-cost allowance. Platform or wrap-account fees sit on top again. Frequent trading quietly multiplies the first two.

When higher fees can be defensible

A higher MER is only worth paying if the strategy delivers something you genuinely can't get cheaply — access to an asset class with no low-cost index option, or a hedging structure you need. Persistent outperformance after fees is rare and hard to identify in advance, which is why low-cost index exposure has become the default for long-horizon investors.

Frequently asked questions

Are fees deducted from my account? Not visibly — they're taken out of the fund's assets, so they show up as a slightly lower unit price rather than a line item on your statement.

Is a hedged ETF worth the extra fee? Currency hedging typically costs a little more and reduces exchange-rate volatility. Over long horizons the currency effect tends to wash out, so the decision is about your tolerance for short-term swings.

Do fees matter less in super? No — the same compounding logic applies, and over a 40-year working life the fee difference on a super balance is usually far larger in dollar terms than on a personal portfolio.
