Fund charges and what they actually cost you

Adviser charges where advice is taken, frequently as a percentage of assets.

And entry, exit and performance fees in some products.

Why small differences matter

The arithmetic.

A charge is deducted every year, which means it removes both the amount charged and the returns that amount would have earned in every subsequent year.

Which compounds against you exactly as returns compound for you.

Over several decades, a difference of a percentage point or so in total costs produces a difference in final value that most people find surprising when they calculate it.

Regulators in several jurisdictions require illustrations showing the effect of charges over time, and they are worth reading rather than skipping.

Percentage versus flat fees

Where the platform choice matters.

Percentage-based platform charges are cheaper for small portfolios and become expensive as the portfolio grows.

Flat-fee platforms are the reverse.

The crossover point depends on the rates, and calculating it for your own portfolio size takes a few minutes and frequently identifies a substantial annual saving.

Some platforms cap percentage charges for certain asset types, which changes the calculation.

And transferring between platforms is possible, generally without selling, though it takes time.

Active fund charges

Where the comparison is starkest.

Actively managed funds charge substantially more than index funds, reflecting research and management.

The evidence on whether that additional cost is recovered in additional return is not encouraging: long-run studies consistently find a majority of active funds underperforming their benchmarks after costs, with the proportion rising over longer periods.

Which does not mean no active manager outperforms — it means identifying them in advance is difficult and past performance is a weak predictor.

Where active management is used, the charge should be justified by something identifiable rather than by the label.

Closet indexing

A specific problem.

Some funds charging active fees hold portfolios closely resembling their benchmark, which means investors pay active charges for index-like exposure.

Regulators in several jurisdictions have investigated this and required disclosure.

Measures such as active share indicate how much a fund differs from its benchmark and are worth checking for any expensive fund.

A fund with high charges and low active share is straightforwardly poor value.

Performance fees

Which require scrutiny.

A performance fee charges a share of returns above a benchmark or hurdle.

The features that matter: whether there is a high-water mark preventing repeated charging on the same gains; what the benchmark is, since an inappropriate one makes the fee easy to earn; and whether the fee is charged on absolute returns regardless of the market.

Asymmetry is the general issue — the manager shares the gains and not the losses.

Reducing what you pay

Practical actions.

Use low-cost index funds for core exposure, where the evidence is strongest.

Compare total cost of ownership rather than the headline charge.

Choose a platform structure appropriate to your portfolio size, and recheck as it grows.

Minimise trading, since each transaction has a cost and frequent trading is associated with worse outcomes.

Use accumulating funds where reinvestment would otherwise incur dealing costs.

Avoid unnecessary currency conversions.

And use tax-advantaged accounts, since tax is a cost like any other.

Where paying more is defensible

For balance.

Regulated advice, for people who would otherwise make serious errors or who face genuinely complex situations.

Access to asset classes not available cheaply.

Platforms offering functionality you actually use.

And, arguably, a structure that stops you interfering with your own portfolio, since the behaviour gap discussed elsewhere on this site frequently costs more than any fee.
