How to Price a Retainer Without Underpricing Your Time
TL;DR
- The most common retainer pricing mistake is scope anchoring to the wrong baseline, often resulting from anchoring retainer price to project hourly rate, which can lead to underpricing of 35 to 55 percent.
- A fractional CMO working 10 hours per month is providing roughly 7 percent of a full-time CMO's time, and using value-based pricing, this translates to $1,167 per month, or $2,334 per month at a 2x value multiple.
- The fully-loaded cost of a full-time CMO at a company can range from $180K to $250K per year, making it a key consideration in determining the replacement cost of retainer services and informing value-based pricing decisions.
Retainer pricing is structurally different from project pricing, and the mistakes people make when moving from project to retainer pricing are different from the mistakes they make with project scopes. The most common retainer pricing mistake is not hourly rate confusion. It is scope anchoring to the wrong baseline.
The Scope Anchoring Problem
Most service providers who transition from project to retainer pricing anchor their retainer price to their project hourly rate. If you charge $150 per hour on projects and a client wants 10 hours of retainer work per month, you quote $1,500 per month. This feels logical and is usually wrong in two directions simultaneously.
First: retainer work is worth more than project work per hour because it provides ongoing strategic value, institutional knowledge accumulation, and availability when the client needs it most.
Second: the 10-hour estimate is almost always wrong. Retainer work expands to fill available time, and 10 hours of work in month 3 looks different from month 1 because you know more, the client asks for more, and the relationship has expanded the scope of what you are implicitly responsible for.
The floor on retainer pricing should not be based on hourly rate times hours. It should be based on the replacement cost of what you provide, plus a premium for availability and continuity.
Value-Based Pricing for Retainers
Value-based pricing for a retainer asks: what would the client need to pay to get equivalent value from another source, and how much of that value are we delivering?
Concretely: if you are providing fractional CMO services, the fully-loaded cost of a full-time CMO at a company of the client's scale is $180K to $250K per year. A fractional CMO working 10 hours per month is providing roughly 7 percent of a full-time CMO's time, but at the highest-value edge (strategy, decisions, execution oversight). Using this framework: 7 percent of $200K equals $14K per year equals $1,167 per month. At 2x value multiple: $2,334 per month. If you quoted $1,500 based on hourly math, you were underpriced by 35 to 55 percent.
Scope Anchoring Correctly
Anchor your retainer scope to outcomes, not to deliverables or hours. Content strategy retainer: we develop the quarterly content plan, brief the writing team, review all published content before it goes out, and do a monthly performance review with you. That is an outcome-anchored scope. 8 hours per month of content consulting is a deliverable-anchored scope.
Outcome-anchored scopes are harder for clients to haggle on because there is no hour to cut. The scope document should specify what is included, what is explicitly excluded, and what constitutes delivery for each outcome. The exclusion list is as important as the inclusion list.
The Floor Principle
Set a personal floor for any retainer engagement: the minimum monthly amount below which you will not work regardless of the scope. For most solo B2B service providers, the floor is between $1,500 and $3,000 per month. Below that level, the administrative overhead is a significant fraction of the revenue, and the relationship does not generate enough to absorb a difficult client month without going negative.
Knowing your floor also protects you in negotiation. When a client says they have $1,200 per month for this and your floor is $2,000, the answer is not to see what you can do for $1,200. It is to present what you could do at $2,000. Accepting below-floor engagements does not lead to good clients. It leads to clients who undervalue you and expect above-floor delivery from below-floor rates.
