Who Gets Paid Along the WayStart here

Between your money and the asset sit six or seven parties, each taking something. Naming every one of them, what they take, and which of them you can remove.

The chain, in order

Money does not go from you to an asset. It goes through a sequence of parties, each of which performs a real function and charges for it. Some of them you chose; several you did not know existed.

The layers you can remove, and the ones you cannot

• Cannot remove: the market maker's spread. Somebody has to take the other side of your order at the moment you want to trade, and immediacy is the service being sold. You can reduce it by trading less and by trading in liquid instruments — see market microstructure.
• Cannot remove: custody. Your securities have to be held somewhere, and the version where they are not properly segregated is the expensive one.
• Can remove: the issuer layer, by holding the assets rather than a promise about the assets. Same exposure, different failure mode — see the wrapper comparison.
• Can reduce: the manager layer, by choosing a rules-based fund over a discretionary one; and the platform layer, by consolidating accounts.
• Can partly reclaim: withholding tax, depending on fund domicile and treaty position. This is a large effect that never appears as a "fee" anywhere.

Where the money actually goes, by product type

• A broad index ETF — most of the cost is the ongoing charge and the spread. The chain is short, the fees are disclosed, and the residual gap is measurable with the tracking-difference decomposition.
• An actively managed fund — the manager layer is the largest, plus the fund's own trading costs, which sit outside the headline charge and are frequently the same size again.
• A structured note — the issuer margin dominates and is taken once, at inception, whatever happens afterwards. The decomposition method is the only way to see it.
• A leveraged position — financing is the dominant cost and it accrues daily, so the cost scales with time held rather than with the number of trades.
• Direct property — transaction taxes and agent fees are enormous relative to any of the above, which is what makes the holding period the decisive variable.

The revenue nobody bills you for

• Payment for order flow. A "zero commission" broker is paid by the venue that receives your order. The cost surfaces as execution quality, not as a charge, and it is genuinely difficult to measure from the outside.
• Securities lending. Your fund's holdings are lent out; the revenue is split between fund and manager, and the split varies enormously between providers. See securities lending.
• Cash balances. Interest earned on uninvested cash in an account, kept in whole or in part by the platform. On a large balance in a high-rate environment this exceeds every disclosed fee combined.
• FX conversion. Buying a dollar security from a euro account converts currency, and the rate used is a decision the platform makes. A 0.5% conversion spread on a round trip exceeds a year of ongoing charges.
• The spread on a product where the issuer is the only market maker. The exit price is set by the party you would be exiting.

Putting a number on the whole chain

• Take every layer's annual cost, add the amortised one-off costs, and run the total through the total cost of ownership calculator for your actual holding period.
• The compounding is the point. Costs are subtracted from the base that would have compounded, so their effect grows faster than they do.
• Compare the total against the dispersion of outcomes you are choosing between. If two funds differ by 0.6% a year in cost and their strategies are near-identical, the cost difference is the entire expected difference in outcome.
• Then check the largest line, which is usually tax. Wrapper choice, domicile and distribution policy routinely move more than every fee on this page.
