What you are actually paying an agency for

Ask an agency what its fee covers and you get a deck about partnership. Ask an ex-agency finance director and you get a spreadsheet. The spreadsheet is more useful, so here is the shape of it.

The fee is a staffing plan, not a price for work

Almost every retainer is built the same way. Someone estimates how many hours of which grades of person your account will consume in a month, multiplies by a chargeout rate, and adds a margin. The number you receive is the output of that arithmetic.

This matters because it means the fee has no relationship to the value of the idea. A line that transforms your business and a line that does nothing cost identically, provided the same people took the same number of hours to produce them.

The chargeout rate is roughly triple the salary

Standard practice, and not in itself dishonest. The multiplier covers employer costs, unbilled time, the building, the finance and HR functions, the new business team, and profit. What it means for you is simple: for every hour of thinking you buy, you are also buying about two hours of infrastructure.

Utilisation is the thing being optimised

An agency lives or dies on how much of its people’s time is billed. That single metric explains almost every behaviour clients complain about: the weekly status call that could have been an email, the strategy phase you did not ask for, the deck that grows to justify itself, the reluctance to tell you a piece of work is unnecessary.

None of it requires anyone to act in bad faith. It only requires everyone to act in their own interest inside a structure that rewards hours.

Then the mechanical work stopped costing anything

A large share of those billed hours were never thinking. They were resizing, versioning, subtitling, localising, cutting down, assembling reports and reading competitor sites. That work now takes a fraction of the time it did.

The saving is real and it is enormous. Very little of it has reached clients, because in an hours-based business the saving is indistinguishable from the margin.

What to do about it

• Ask for the staffing plan behind the fee. Names, grades, hours. A refusal is itself an answer.
• Buy jobs, not months. A retainer prices availability; you want output.
• Ask which deliverables exist because you need them and which exist because the retainer needs filling.
• Get the price in writing before the work starts, and treat any change as requiring re-approval.
• Insist the ad accounts, pixels and data sit in your name from day one.

None of that requires leaving your agency. It just moves the conversation onto ground where you can actually see what you are buying.
