How to price a marketing agency retainer (and stop giving work away)
A practical method for pricing drawdown retainers by department, setting the overage rule, and measuring the servicing gap so the retainer stays profitable.
Start from departments, not a lump sum
A $15,000 retainer is not one number. It is a plan for how much SEO, content, social and PR the client gets this month. Price each department's share from the people who will do the work and their actual rates. The split will change month to month because that flexibility is the value you sell, but the starting split is what keeps the first month honest.
Write the overage rule down
The most common way agencies lose money on retainers is silently absorbing extra work. The rule that fixes it is simple: if the client needs more than the retainer covers this month, they approve and pay an overage before the work happens, the cap rises for that period, and it resets next period. Put it in the agreement and make it visible on the client's usage statement.
Measure the servicing gap
Every month, compare the value the team delivered (hours at billing rate) to what the retainer paid. The difference is the servicing gap. A gap of 10% is normal goodwill; a gap of 40% means the account is priced wrong or the scope is not being managed. Most agencies never see this number because their tools report delivered value as revenue.
- Green: delivered value within 10% of the retainer.
- Amber: 10–25% over. Talk to the client about scope.
- Red: more than 25% over for two months. Reprice at renewal.
Reprice at renewal with evidence
Renewal conversations go better with a year of usage statements than with a feeling. Show the client where the retainer went, where the gap was, and what a right-sized retainer looks like.
Questions this article answers
- What margin should an agency retainer target?
- Most healthy agencies target a 50–60% gross margin on labour (revenue minus fully loaded delivery cost) and a 15–25% net margin after overhead. A retainer priced from realistic hours at each person's rate with a 55% labour margin target is a sound starting point.
- Should unused retainer hours roll over?
- Only as a deliberate decision at period close, and usually only partially. Automatic rollover erodes the retainer model; an explicit carryover credit the account manager chooses keeps the client goodwill without making the budget unpredictable.
- Time tracking that agency teams actually do
Why time tracking fails in agencies, and the six settings that make it stick: rounding, notes, approvals, locks, targets and visibility.
- Agency profitability: hours × rate is lying to you
Why the standard profitability report overstates revenue and hides idle time, and how to compute real margin from contracted revenue and absorbed cost.
- White-label client reporting: what 'on your own domain' should actually mean
The checklist for reports that look like they came from your agency: domain, fonts, colours, footer, email identity, and the metrics that must never be overwritten.
