What should a marketing agency retainer actually cost?
There is no market rate, and anyone quoting you one is quoting their own staffing plan. Here is how to work out what your number should be, and how to tell whether the one you were given is defensible.
The honest answer to this question is that nobody can tell you a number without knowing your staffing plan, and any agency that gives you one before asking about scope is quoting its own capacity, not your needs. That is unsatisfying, so here is the method instead.
Start from output, never from budget
The most common way to get a bad retainer is to open with a budget. The moment an agency knows the number, the scope is reverse-engineered to fill it. Every deliverable that appears afterwards exists because the fee needed justifying.
Write the output list first, in plain language, with quantities. Twelve social assets a month. One brand film a quarter. Media managed across two platforms. Then ask what that costs. You will get wildly different numbers, and the differences will be informative.
Work out the floor
Every retainer has a floor set by arithmetic. Estimate the senior hours your scope genuinely needs in a month. Multiply by a realistic hourly cost for that seniority in your market. Multiply again by three, which is roughly the chargeout multiple agencies work to.
That is the floor. A quote far below it means juniors will do the work. A quote far above it means you are funding something other than your account, and you are entitled to ask what.
The four questions that reveal everything
- What is the staffing plan? Names, grades, hours per month. This is the fee. If it will not be shared, that is your answer.
- Which deliverables would you cut if the fee dropped 20%? An honest agency has a ready answer. It also tells you which items were padding.
- Who is on this account in month four? The pitch team almost never is. Get the month-four names.
- What is marked up? Media, production, talent, licences. Ask for the percentage in writing.
Retainer or project?
A retainer prices availability. A project prices output. If your needs are genuinely continuous and unpredictable, availability is worth buying. If they are not, you are paying a subscription for a thing you consume occasionally.
Most marketing teams sign retainers because it is administratively easier, then spend a year quietly resenting them. Buy the first job as a project. You will learn more about the agency in six weeks of real work than in any pitch.
What a defensible number looks like
- It is built from a staffing plan you have seen.
- It maps to a deliverable list with quantities.
- It can be reduced by cutting named items, not by vague trimming.
- It has no notice period longer than the value it delivers in one cycle.
- Pass-through costs are pass-through, and you can see the invoices.
If your current retainer fails three of those, the fee is probably not your problem. The structure is.
