The $100-an-hour tax on flat-fee advice

The most useful number in the flat-fee debate is also the one most practices would rather not see: an advisor billing an average $300 an hour spends nearly two hours on unbillable work for every hour a client pays for. That math, laid out by Sydney Squires, senior financial planning nerd at Kitces' Nerd's Eye View, is the quiet reason so many fee-only shops drift back toward AUM pricing despite the philosophical appeal of charging for advice rather than assets.

Squires' Aug. 31 piece sorts the fee-only world into its actual shapes: advisors who bundle financial planning into an AUM fee, flat-fee practices running on retainers, hourly and project-based engagements, and advice-only firms that do no investment management at all. The flat-fee and subscription models carry a genuine marketing advantage (they connect what clients pay with the advice they receive), which makes them a natural fit for clients with larger portfolios who are sensitive to what a 1% fee means in dollars. But revenue per client tells a different story: relative to an AUM advisor, a flat-fee advisor often does comparable work while generating substantially less revenue per client, Squires writes.

The work advisors do has shifted from product sales to investment management to holistic planning and behavioral coaching, she notes, but pricing has lagged the workload. AUM was the compromise between the old sales model and the new advice work; flat fees are the attempt to price the advice itself. The problem is that advice is only half the job—prospecting, marketing, compliance, administration—where flat-fee pricing tends to break, and the hourly math shows why.

Advisors charge an average of about $300 per hour, Squires reports, while spending nearly two hours on unbillable activities for every billed hour, which puts the realized rate near $100 an hour before any overhead is loaded on. Set that against the AUM advisor the piece describes, where a 1% fee on a $1 million client serviced for roughly 21 hours a year works out to an effective rate near $500 an hour, and the flat-fee advisor is doing comparable work for a fifth of that rate. That gap is the real competitor to the flat-fee model—not AUM as a philosophy but AUM as a pricing mechanism.

Squires' point is less that flat fees can't work than that the fee has to cover the whole cost of serving a client: not just the meeting and the plan, but prospecting, marketing, compliance, administration, implementation support, and the hours that go into a new client before the first billable deliverable. The viability of a flat-fee model, she writes, depends less on whether an advisor can charge a flat fee and more on whether that fee is priced appropriately. A practice that sets its retainer by dividing desired income by number of clients is pricing the meeting; one that adds up the true service cost plus a margin is pricing the business.

Her recommended first step is almost anticlimactic in its simplicity: track time. Even a month of time tracking, Squires writes, can reveal how much work actually goes into servicing each client, especially new clients—for most practices, the discovery will be uncomfortable, whether it is the client paying the same retainer as everyone else but consuming many more hours, or the implementation work that never appears on a meeting calendar. The answer is to reprice the book, because a flat fee is a cost estimate and, like any cost estimate, it needs data behind it; a month of tracking produces that data, and an annual review of it keeps fees from drifting as client needs shift.

The broader lesson is about how AUM survives even among advisors who say they have left it. Squires notes that many fee-only advisors end up incorporating AUM into their pricing because it functions as a proxy for client complexity and because it automatically increases revenue as the advisor's experience grows. AUM does the escalation work flat fees don't, so an advisor who wants to stay flat-fee has to build that same escalation into the pricing manually—fees that rise as expertise grows, and fees that vary with client complexity rather than a single rate for every engagement.

A practice that tracks time for a month and comes out with a client-by-client cost map has the raw material to reprice its entire book by complexity. The practice that simply surrenders to AUM because its first flat-fee pricing pass produced starvation wages is confusing a price problem with a model problem. Flat-fee advice's whole-value promise is only redeemable when the fee covers the unbillable half of the job, and the advisors who make flat fees work will be the ones who treat the time log as a pricing asset rather than an administrative chore—and who collect a retained equivalent of $500 an hour instead of $100.
