A fund that reports a 5% gain for the year has already paid its manager, its custodian and its broker. The number on the factsheet is net. Understanding which deductions came first, and which ones the contract lets the provider change, is the difference between modelling a return and guessing at one.

The Return That Never Arrives

Fees are subtracted from the pool of assets before performance is measured, not billed to you afterwards. A fund holding assets worth a thousand units and charging 2% a year removes twenty units from the pool regardless of whether the year was good. The remaining assets produce the return you read about.

That ordering is why a 5% gross gain can appear as a 3% net gain. The gross figure describes what the holdings did. The net figure describes what you own. Marketing material tends to lead with the first and disclose the second in a table several pages deeper.

The mechanics are contractual, not discretionary. A prospectus sets out what may be charged, to whom, and how often. Some charges are fixed percentages; others are capped subject to board approval; a few can be reinstated if the manager decides to stop waiving them. Each of those is a term you agreed to at purchase.

Two Layers of Deduction

The first layer sits inside the fund. The expense ratio is the annual cost of running the portfolio, expressed as a percentage of assets. It covers management, administration, custody, audit and the ordinary operating expenses of a collective vehicle. You never see an invoice for it; it is taken continuously from the pool.

The second layer sits at the account. Brokerage commissions are charged per trade, and they are visible in a way fund costs are not. Platform fees, custody fees and account maintenance charges sit somewhere between the two: deducted from your cash balance, often quarterly, frequently overlooked because they arrive as a line item rather than a bill.

The honest aggregate is the total expense ratio, or TER. It divides total annual cost by the fund's average assets over the year. Because the denominator moves with markets and the numerator includes one-off items, the TER normally varies somewhat from year to year. A single year's figure is a sample, not a constant. This site has looked at the securities lending terms in a prospectus, which sit alongside the fee table and change the economics in similar ways.

How the Schedule Is Written

Prospectus terms bind the investor, not the manager's goodwill. The document will state a management fee as a percentage of net assets, describe how that fee is accrued, and identify who calculates it. It will also list the other expenses the fund may pay, sometimes with a cap and an expiry date on that cap.

The arithmetic is simple even when the disclosure is not. Annual cost divided by average assets gives the ratio. A fund with 500 million in average assets and 7.5 million in total charges runs at 1.5%. If assets halve while fixed costs hold, the ratio rises without anyone raising a fee.

Trailing commissions and revenue-sharing arrangements complicate the picture. A distributor may receive a slice of the management fee for directing money into a fund, and that slice comes out of the same pool. The investor pays it either way. Whether the arrangement is disclosed prominently depends on the jurisdiction and the distributor.

The Drag on Compounding

Small percentages compound into large sums because they compound against a growing base. A 1% annual charge on a portfolio earning 5% gross consumes roughly a fifth of the return in the first year and a larger share of the final balance over decades, since the fee is levied on assets that would otherwise have grown.

Costs also raise the break-even. A fund charging 2% must earn 2% before you see a penny. In a year when the underlying holdings return 1%, the net result is a loss. That is not a market event; it is arithmetic that was fixed at purchase.

Timing matters within the year. A fee accrued daily against a volatile asset base extracts more in cash terms when assets are high and less when they are low. A fee charged annually in arrears does the opposite. Two funds with identical headline ratios can produce different net outcomes for that reason alone.

Active, Passive and the Price of Both

Actively managed funds typically carry higher expense ratios than index-tracking ones, and the gap is wide enough to matter. Where a passive vehicle might sit somewhere in the low tenths of a percent, an active fund covering the same market can run several times that, often in the 1–2% range and occasionally above it. The manager is charging for selection, and the charge arrives whether or not the selection works.

This creates a trade-off that is easy to state and hard to price. A higher fee buys research, trading and oversight, and in some markets and asset classes that spending plausibly adds value. In large, liquid, heavily covered markets it is much harder to demonstrate that the added cost is recovered. The fee is certain; the outperformance that would justify it is not.

Performance figures published for active funds are usually shown net of the expense ratio, which is the correct basis for comparison but easy to misread. A fund that beat its benchmark by a percentage point did so after fees, which means its gross advantage was larger. A fund that trailed by a point may have been ahead before the manager was paid. Neither fact tells you what happens next year, and the fee will be charged next year regardless.

What the Contract Actually Says

Fee tables are buried in disclosure documents for a reason, and the reason is not length. Redemption fees and exit charges penalise leaving, sometimes on a sliding scale that falls to zero after a set holding period. Inactivity fees and account maintenance charges apply when you do nothing at all.

Currency conversion is the quietest cost in the schedule. A fund holding foreign assets converts dividends and settles trades at a spread to the interbank rate, and that spread is revenue for the party executing it. It rarely appears as a percentage in the fee table because it is embedded in the exchange rate applied.

The objection worth taking seriously comes from providers themselves: granular disclosure is expensive to produce and harder for ordinary investors to use than a single number. That argument has some force. It also tends to be made by firms whose single number is unflattering. A related piece on what insurers keep from each premium dollar makes the same point about a different product.

Check the Fee Table First

Compare total expense ratios across candidate funds rather than headline returns, because the headline already nets out a cost you have not yet verified. A fund with a strong record and a 2.2% TER may leave less than a duller one at 0.4%.

Request the full fee schedule in writing before opening an account, including platform charges, custody charges and any fee the provider reserves the right to introduce. If a charge appears only in a general terms document, ask which clause permits it.

Model net returns yourself: take a conservative gross assumption, subtract the TER, subtract the platform fee, then subtract an estimate for trading and conversion costs. The residual is the number to plan around.

Ask directly whether the distributor receives revenue sharing on any fund you are being offered, and in what amount. Then diarise an annual review, since terms change and waivers expire. The same discipline applies to checking a beneficiary designation before the will: the document, not the assumption, controls.
