Fee-Only vs. AUM vs. Commission Advisors

The three ways advice gets paid

Account Churning, Commissions, and Advisor Conflicts of Interest taught the one question — how exactly are you paid? — and this chapter maps the full answer space, because at high wealth the differences between compensation structures compound into six figures. Three families, decoded by their incentive gradients.

Commission — paid per transaction and per product placed. The gradient: toward activity, toward products with the richest payouts (High-Commission Insurance Products's insurance economics live here), away from "do nothing" and from anything unpaid (index funds, debt paydown). Regulated to best interest at the recommendation moment (Account Churning, Commissions, and Advisor Conflicts of Interest's Reg BI) — but the gradient operates within compliance, in what gets brought up.

AUM percentage — paid on assets under management. The gradient is subtler and worth spelling out precisely because it's marketed as conflict-free: toward gathering and retaining assets under the fee — which tilts against every legitimate use of money that leaves the managed pool: the mortgage payoff, the real-estate purchase, the large gift or early giving (Die With Zero Thinking), the annuitized income floor (Safe Withdrawal Thinking), even aggressive spending in retirement (The Over-Saving Trap's trap gets a structural ally). The advisor may be excellent and the advice sound — the gradient still exists, and it always points the same direction: keep the assets where the fee lives.

Flat-fee / hourly / advice-only — paid for the work itself. The cleanest gradient (toward the client's return business), with its own honest limits: episodic engagement (no standing behavioral backstop unless retained — The Advisor Decision in Retirement), and quality varying exactly as it does everywhere the price doesn't signal it.

Fiduciary status crosses all three (Account Churning, Commissions, and Advisor Conflicts of Interest's ladder): "fee-only fiduciary" is the phrase that pins both the structure and the standard — worth asking for by name, in writing. The industry maintains a deliberate ambiguity worth knowing here: "fee-based" sounds identical to "fee-only" but can include commissions underneath, so the word "only" is load-bearing.

Matching structure to need

The high-wealth conclusion assembles from Chapters 12.6 and 14.1: buy planning as planning (flat-fee), buy tax work as tax work, buy management at management's commodity price, retain a standing relationship if the behavioral service genuinely earns it — and let every structure answer the one question annually, in dollars (the AUM Fees conversion), against the itemized alternative. The structure that survives that comparison, whatever it is, is the right one — the comparison itself is the discipline.
