Retainers are the backbone of a healthy agency. They create predictable revenue, build deep client relationships, and let your team do their best work without the constant pressure of winning new projects. But they're also where agencies chronically undercharge — often by 30–50% relative to the actual value delivered.
This post is about fixing that. Here's a practical framework for pricing retainers, structuring the scope, and presenting the number so clients actually say yes.
The Three Retainer Models
Before you can price a retainer, you need to decide what kind of retainer you're selling. There are three main models, and each has different implications for scope, pricing, and client expectations.
Model 1: Hours-Based Retainer
The most common model, and the most problematic. The client pays for a block of hours per month (say, 20 hours at $150/hour = $3,000/month). Simple, easy to understand, and immediately adversarial.
Why adversarial? Because the client's incentive is to use every hour they paid for. Your incentive is to work efficiently and finish early — which the client reads as not getting their money's worth. You also cap your upside: a more experienced team that delivers results faster gets punished by this model.
When it works: For clients who need defined, variable support (e.g., "we need someone on call for design work as-needed"). Set a monthly minimum and cap.
Model 2: Deliverables-Based Retainer
The client pays a fixed monthly fee for a defined set of deliverables — for example, "four blog posts, eight social graphics, and one monthly performance report." Cleaner scope, easier conversations, and no hour-counting.
This model works best when your output is consistent and measurable. The risk is scope creep: "can we just add one more thing" is the phrase that quietly erodes your margin every month.
When it works: Content, social media, SEO, and other service lines with repeatable, tangible outputs. Pair it with a clear change-request process to protect your scope.
Model 3: Outcomes-Based Retainer
The most sophisticated and the most lucrative. The client pays for a specific outcome — "we'll grow your organic traffic by 40% in six months" — and you have full discretion over how to get there. Priced on the value of the outcome, not the cost of your inputs.
This model requires confidence in your process and a client who understands value-based pricing. It also requires very clear goal-setting upfront. But when it works, your margins are excellent — and the conversation about renewal is easy because the outcome speaks for itself.
When it works: Performance marketing, SEO, paid media, conversion optimisation — any service where you can quantifiably move a metric the client cares about.
How to Scope a Retainer Without Getting Burned
Bad scoping is the #1 cause of retainer burnout. You win the client at $3K/month, do $6K worth of work for six months, and then either raise the price (awkward) or quietly resent the relationship.
The fix is a proper scoping conversation before you quote anything. Ask:
- What does a successful month look like in six months?
- What tasks or outputs are you expecting every month?
- Who on your side will we be working with? How much of their time can we access?
- What's currently broken or missing that you want us to solve?
Then build your scope from the answers — not from a guess about what the client will pay. Price the scope. Not the other way around.

How to Price It: The Value Anchor Method
Most agencies price retainers by calculating their costs and adding a margin. That's a floor, not a price. Pricing should be anchored to value — what is your work worth to the client?
A simple exercise: if your SEO retainer delivers an extra 500 qualified leads per month to a client who converts 5% of leads at a $2,000 average deal value, that's $50,000 in additional monthly revenue. Charging $3,000/month is an extraordinary deal for them. Charging $6,000/month is still a 8×+ return. The number you quote starts to look different when you do this math.
Build this value calculation into your proposal. Show the client the math. "Based on your current conversion rate and deal value, getting you to X leads per month is worth approximately $Y to your business." Then present your fee below that number. Suddenly the sticker shock disappears.

Presenting the Price: Three Tiers, Not One Number
Never present a single retainer price. Always present three tiers — a good/better/best structure. This does two things: it anchors the client's reference point at the top tier (making the middle feel like a deal), and it turns "should we buy?" into "which one do we choose?"
Structure your tiers around scope expansion, not just price. Tier one might be the core service. Tier two adds a second channel or faster delivery. Tier three includes strategy, reporting, and a quarterly review session. Each tier is a coherent package — not a bolt-on of extra hours.
Most clients land on the middle tier. Design the middle tier to be the one you actually want to sell.
The Renewal Conversation
Getting a client on retainer is half the battle. Keeping them — and growing the relationship — requires a consistent rhythm of demonstrating value. Monthly or quarterly reporting, clear attribution of your work to their outcomes, and a proactive renewal conversation 60 days before the contract ends.
Never let a retainer auto-renew on the same terms without revisiting the scope. Either expand the engagement (upgrade the tier) or reaffirm the value. Both are better than silence.
