How to Price Agency Retainers

How to Price Agency Retainers

(Without Undercharging Yourself)

Retainers are the closest thing a marketing, digital or PR agency gets to a steady heartbeat. Predictable monthly income makes it easier to plan hiring, manage cash flow and sleep at night. But a badly priced retainer is worse than no retainer at all. It locks you into a fixed fee while the work quietly expands, and you end up subsidising your clients.

This guide walks through how to price retainers properly: what to work out first, which models are worth considering, and how to keep the arrangement profitable once it’s up and running.

Start With Your Numbers, Not Your Competitors

It’s tempting to look at what other agencies charge and pitch just under it. That tells you very little. Their cost base, team and positioning aren’t yours.

Begin with three things:

Your cost of delivery. This means the real cost of the people doing the work: salaries, employer National Insurance, pension contributions, holiday and sick pay, plus freelancers and any tools or software used specifically for that client. Many owners forget the on-costs and so understate what an hour of their team’s time actually costs.

Your overheads. Rent, insurance, software subscriptions, accountancy fees, management time, training and the unglamorous admin that keeps the lights on. These need to be covered by the work you sell, not ignored.

Your target margin. Decide what profit you want the agency to make. Many owners price to cover costs and hope profit appears. Instead, set a margin target first and work backwards. Your accountant can help you work out a sensible figure based on your size and growth plans.

Once you know what an hour of delivery really costs, and what proportion of your team’s time is realistically billable, you can calculate a rate that works. Remember that nobody is billable 100% of the time. Pitching, training, internal meetings and quiet periods all eat into capacity.

Pick a Pricing Model That Fits the Work

There’s no single right way to structure a retainer. The best model depends on how predictable the work is and how much your client values outcomes versus activity.

Hours-based retainers

The client buys a block of time each month at an agreed rate. It’s simple to explain and easy to track, which makes it a popular starting point. The downside is that it ties your income to time rather than value, and it can invite clients to scrutinise every hour. Faster, more skilled teams are effectively penalised for being efficient.

Deliverables-based retainers

Here the client pays for a defined output: four blog posts, one press campaign, a monthly report, a set number of social posts. This works well when the work is repeatable and you understand how long each item takes. It keeps conversations focused on what’s being produced rather than hours logged, but you need to be precise about what counts as a deliverable and how many rounds of revisions are included.

Outcome or performance-linked retainers

Part of the fee depends on results, such as leads generated, revenue or coverage secured. These can be attractive to clients and lucrative when things go well, but they carry risk, particularly where results depend on factors you don’t control. If you go this route, consider a base fee that covers your costs, with performance elements as a bonus on top.

Tiered packages

You offer, say, three levels of service at different price points. Clients self-select, and you avoid building a bespoke quote every time. Tiers also give you a natural upsell path. The key is making sure each tier is genuinely profitable, not just the top one.

Value-based pricing

Instead of building the fee from costs, you price based on what the work is worth to the client. If your campaign could plausibly generate hundreds of thousands in sales, a fee based purely on hours undersells it. This takes confidence and a clear understanding of the client’s economics, but it’s often where the healthiest margins are found. Even then, check the numbers against your costs so you know the floor.

Many agencies blend these approaches, for example a deliverables-based core with a pool of flexible hours for ad hoc requests.

Scope It Like You Mean It

Pricing is only half the battle. Scope is where retainers tend to go wrong.

Write down exactly what’s included and, just as importantly, what isn’t. Cover things like:

– The specific services and deliverables each month
– The number of revision rounds
– Meeting frequency and who attends
– Reporting format and timing
– Response times for requests
– How out-of-scope work is quoted and charged

A good scope document isn’t about being rigid. It gives you a calm, professional way to say, “That’s outside what we agreed. Shall we add it or swap it for something else?” Without it, scope creep becomes a slow leak in your margin.

Build in Room for the Unexpected

Clients rarely ask for exactly the same thing every month. Campaigns change, priorities shift and urgent requests appear. Factor in a sensible buffer for account management, communication and small extras. Account management in particular is often unpriced. Calls, emails, check-ins and strategy conversations take real time and should be part of your calculation.

Check Your Margin Per Client

Once retainers are running, track the time your team actually spends against what the retainer brings in. Even a simple monthly review will tell you which clients are profitable and which are quietly costing you money.

Look at effective hourly rate: monthly fee divided by hours actually worked. If it’s consistently well below your target rate, you’ve got a pricing or scope problem to fix. Do this regularly rather than waiting for the annual review, by which point you’ve lost months of margin.

Contract Terms That Protect You

A retainer is only as secure as its agreement. Sensible terms to consider include:

Minimum term. Three to six months is common, giving you time to get going and recoup onboarding effort.
Notice period. Typically one to three months, so you’re not left with a sudden hole in revenue.
Payment terms. Invoice in advance where you can, ideally by direct debit, to protect cash flow.
Annual review. Build in a scheduled price review, ideally with an inflation or cost-of-living adjustment.
Unused allowance. Decide in advance whether unused hours or deliverables roll over or expire. Clear rules prevent awkward disputes.

It’s worth having a solicitor check your standard agreement, particularly if you’re making commitments around performance or intellectual property.

Don’t Forget VAT and Tax

If your agency is VAT-registered, retainer fees will usually attract VAT, so be clear whether your quotes are inclusive or exclusive. Quote exclusive of VAT for business clients to avoid confusion. If you’re approaching the VAT threshold, retainers can push you over it faster than you expect, so keep an eye on your rolling 12-month turnover.

Also think about how retainer income is recognised in your accounts, particularly if you invoice in advance or have unused allowances. Your accountant can advise on the correct treatment for your situation.

Raising Prices on Existing Retainers

Underpriced retainers can be corrected, but it takes planning. A few principles help:

– Give plenty of notice, and don’t surprise anyone.
– Explain the reasons: increased costs, expanded scope or the results you’ve delivered.
– Offer options, such as paying the new price for the existing scope, or keeping the current price with a reduced scope.
– Make annual increases a normal part of the relationship from day one, so they never feel like a shock.

Most good clients would rather pay a fair price and keep a team that’s motivated and well resourced than lose you.

Common Mistakes to Avoid

Pricing from gut feel. Without knowing your costs and margin, you’re guessing.
Discounting to win the deal. Early discounts tend to become permanent. Reduce scope instead of price if you need to be flexible.
Vague scopes. If it isn’t written down, it will expand.
Ignoring account management time. It’s real work and belongs in the price.
Never reviewing. Costs rise, scope drifts and a retainer that was profitable a year ago may not be now.

Bringing It Together

Good retainer pricing comes down to a handful of habits: know your true costs, set a margin target, choose a model that suits the work, define scope clearly, track profitability and review regularly. Do that, and retainers become what they’re meant to be: reliable income that lets you plan, invest and grow.
