Ask ten consultants how they priced their retainers and you'll get ten versions of the same answer: "I guessed a monthly number that felt about right." That guess is usually too low, structured badly, and quietly bleeding margin — because a retainer priced on a hunch has no logic to defend when the client asks for more.
A retainer is the most valuable pricing model you have. It converts unpredictable project income into recurring, forecastable revenue, and it's the difference between hunting for the next engagement every month and building something that compounds. But only if the price is built on a framework instead of a feeling. There are three real ways to price one — hours-based, deliverables-based, and access-based — and each answers a different question about what the client is actually buying.
This is a guide to the pricing itself: how to arrive at the monthly number. Whether a retainer is even the right structure versus a one-off project is a separate decision — if you're still weighing that, start with Project vs. Retainer: How to Structure Consulting Engagements. And once you've priced it, the language that keeps the scope from ballooning is its own discipline, covered in The Consultant's Guide to Retainer Agreements. Here, we're solving for the dollar figure.
Start from your effective hourly rate
Every retainer framework — even the ones where the client never sees an hour — is built on top of one number: your effective hourly rate. It's the floor beneath all three models. If you haven't nailed it down, do that first; working backward from your target income, overhead, and realistic billable hours is what the consulting rate calculator is for. For the worked examples below, we'll assume an effective rate of $185 an hour. Substitute your own and the logic holds.
With that anchor in place, the question becomes: what is the client paying for — your time, your output, or your availability? That's what separates the three frameworks.
Framework 1: Hours-based retainers
The client pre-buys a block of your time each month. It's the most transparent model and the easiest to sell to a nervous or newer client, because they can see exactly what they're getting: hours.
The pricing question is whether reserved hours cost more or less than ad-hoc hours. Both schools are defensible. Some consultants give a modest volume discount to reward the guaranteed commitment; others charge a small availability premium because reserved capacity has a real cost — those hours can't be sold to anyone else.
Worked example, discount version: 10 reserved hours a month at a 10% commitment discount is $166.50 an hour, which you'd round to a clean $1,650 per month — $19,800 a year of predictable revenue from a single client. Worked example, premium version: the same 10 hours at your full $185, billed as guaranteed priority capacity, is $1,850 per month, or $22,200 a year.
The detail that makes or breaks an hours-based retainer is the rollover policy. Use-it-or-lose-it is cleanest for you — unused hours expire at month end, which protects your capacity and your margin. A one-month rollover is more client-friendly but risks a client hoarding hours and then dumping 20 hours of work on you in a single week. Whichever you choose, name it explicitly in the agreement. Ambiguity here is the single most common source of retainer resentment.
Framework 2: Deliverables-based retainers
Here the client buys a defined output each cycle, not a quantity of your time: "two finished strategy briefs and one monthly review call," "an end-of-month financial close," "a quarterly board deck plus monthly check-ins." The hours are your business; the deliverable is theirs.
This is where you stop selling time and start selling outcomes — and it's usually the higher-margin model, because the price floats free of the clock. You estimate the hours internally to protect yourself, then price on the value of the output.
Worked example: suppose the monthly deliverable realistically takes you about 12 hours. At $185, that's a $2,220 floor. But you don't price at the floor — you price on what the predictable, packaged output is worth to the client, and on the fact that they never have to think about it. So you price at $2,500 per month. If you get faster and the work starts taking 9 hours instead of 12, your effective rate quietly climbs from $185 to $278 an hour — and the client is just as happy, because they're paying for the brief, not the stopwatch. That's the structural advantage of deliverables-based pricing: efficiency rewards you instead of penalizing you.
The risk to manage is scope. When you sell a deliverable, you must define it with enough precision that "two strategy briefs" doesn't quietly become "two briefs plus unlimited revisions plus a weekly call I didn't quote." Specify the output, the number of revision rounds, and what sits outside the package.
Framework 3: Access-based retainers
The client buys your availability — priority access, a guaranteed response time, a standing place in your calendar — rather than a fixed number of hours or a specific deliverable. "You can reach me, I'll respond within 48 hours, and I'll hold roughly a day a month for your needs." Some months they lean on you hard; some months they barely call. They're paying for the certainty that you're there.
This is the highest-margin model and the hardest to earn, because it only works once the client trusts your judgment enough to value the option of your attention. It's the model senior advisors and fractional executives run on.
Worked example: you offer priority access with a soft cap of around 8 hours a month, priced at a flat $2,000 per month. In a heavy month where they use the full 8 hours, that's $250 an effective hour — a healthy premium over your $185 base. In a light month where they use 3, it's $667 an hour. The averaging is the point: you're compensated for reserving the availability whether or not it's consumed, the way a retainer for a lawyer works. The "soft cap" language matters — it sets an expectation without turning the relationship into hour-counting, and it gives you a natural, non-confrontational moment to have a scope conversation if a light-touch client starts consistently blowing past it.
Access-based pricing demands the most trust and the clearest boundaries. Get either wrong and you've sold unlimited access to your life for a flat fee. Get both right and it's the most profitable, lowest-effort revenue you'll ever book.
Which framework fits which client
The frameworks aren't ranked — the right one is a function of the client, the relationship's maturity, and what the client actually loses sleep over. Use this to match the model to the situation:
- Choose hours-based when the relationship is new, the client wants cost control and transparency, or they're nervous about "paying for nothing." Visible hours build trust early. It's the natural on-ramp retainer.
- Choose deliverables-based when the work produces recurring, predictable output — content, reporting, reviews, closes — and the client cares about the result more than the mechanics. It's also your best margin lever once you're efficient at the work.
- Choose access-based when the relationship is established, the client's real need is "I need you reachable and thinking about my business," and they trust your judgment. It's a model you graduate into, rarely one you open with.
A common and effective path is to open a relationship on an hours-based retainer, prove the value, and then convert to deliverables- or access-based pricing at the first renewal — where your margin improves and the client's experience gets simpler at the same time.

Set a floor, then price above it
Whatever framework you choose, run one final check before you send the number: does the monthly fee, divided by the hours you realistically expect to spend, clear your effective hourly rate? That's the floor. If a retainer prices out below your ad-hoc rate, you've accidentally given a discount for the privilege of being locked in — the opposite of what a retainer should do. Drop your expected hours into the rate calculator against the monthly fee and confirm the effective rate lands where it should.
Price the retainer on a framework, floor it on your real rate, and define the scope precisely enough that the model holds. Do that and a retainer stops being a monthly guess and becomes the most dependable line in your business.
