How to Price a Monthly Retainer
Quick answer
Price a monthly retainer the same way you'd price anything: start from your hourly floor, multiply by the hours the work will realistically take each month, and add a margin. A $75 floor across 20 monthly hours is a $1,500 retainer — before any premium for priority access or the value you deliver. The hard part isn't the maths, it's the discipline: cap the included hours, track your real time, and charge for anything beyond the cap. Skip that, and the retainer that felt like stable income quietly turns into unlimited work for a flat fee. This is how to set one that stays profitable.
Key takeaways
- Build from your floor. Hourly floor × realistic monthly hours + margin = retainer.
- Cap the hours. State the included hours explicitly; bill overage at a set rate.
- Track your real time. The only way to know if the retainer is actually profitable.
- Scope creep is the enemy. "Quick" extras are how 20 priced hours become 30 unpaid ones.
- Bill upfront. Charge at the start of each month, first month on signing.
- Limit rollover. Unlimited banked hours wreck your capacity.
- Put it in writing. Scope, hours, overage rate, notice period, late fees.
- Review yearly. Re-scope and raise as the client's needs grow.
Why use a retainer at all?
A retainer is a fixed monthly fee for a defined, ongoing scope of work, paid in advance. For freelancers it's the antidote to feast-and-famine: instead of hunting for the next project every few weeks, you have predictable income you can plan around. For clients, it's a dependable partner and a budget line they don't have to re-approve every month. That's why retainers show up across so many freelance fields — from a social media manager on $500–$7,000 a month to a virtual assistant at $600–$2,000 to a bookkeeper at $300–$1,500 per client. Different numbers, same structure — and the same trap waiting if you price it wrong.
The formula: how to actually price it
There are two honest ways to arrive at a retainer number, and the best quotes use both as a check on each other.
1. Hours-based (your floor). Start with the rate you genuinely need — your hourly floor from your income, costs, and taxes. Estimate the hours the work will realistically take each month, multiply, and add a margin. Twenty hours at a $75 floor is $1,500. This is your minimum; pricing below it means you're subsidising the client. The Hourly Rate Calculator gives you that floor, and the logic mirrors building any project quote.
2. Value-based (the ceiling). What is the outcome worth to the client — the leads generated, the hours freed, the books kept audit-ready? When the value clearly exceeds the hours-based figure, you can charge a premium above your floor, especially for priority access and the certainty of having you on call.
Quote the higher of "what it's worth" and "what I need" — never less than your floor. And add a modest premium for the commitment itself: a retainer reserves your capacity, and that reservation has value even in a quiet month.
The trap: why retainers quietly become a pay cut
This is the single most important section, because it's where most retainers go wrong. The fee looks great on day one and erodes from there.
Scope creep is invisible month to month. You agree 20 hours. Then it's "could you also handle this?" and "just one quick thing" — each small, all unpaid, and together a second job. By month three you're working 30 hours for a 20-hour fee, and your effective rate has quietly collapsed while the headline number looks unchanged.
The headline rate lies; the effective rate tells the truth. A $1,500 retainer is $75 an hour at 20 hours and $50 at 30. The only way to know which one you're actually living is to track every hour, even on a flat fee — the same discipline that decides whether a video editor's project fee or a bookkeeper's monthly rate is real or imaginary.
The fix is a cap. State the included hours, and bill anything beyond them at a defined overage rate. That single sentence in your agreement is what keeps a retainer a fair deal instead of a slow slide into being busy but broke — the classic fate of freelancers who undercharge without realising it.
How many hours should the retainer include?
Only as many as you can reliably deliver at the price — and never leave it open. "Ongoing support" with no number is an invitation for the work to expand to fill whatever the client wants. Decide the included hours, write them down, and set the rules around them:
- Included hours: the cap your price is based on (e.g., "up to 20 hours per month").
- Overage rate: what you charge per hour beyond the cap, billed monthly.
- Rollover policy: usually "use it or lose it," or a small rollover that expires after one month — never unlimited banking, which lets a client dump three months of work on you at once.
What to put in the retainer agreement
A retainer is a product, so define it like one. The agreement should state:
- Scope. Exactly what's included — and a short list of what isn't.
- Included hours and overage rate. The cap, and the price beyond it.
- Fee and payment terms. The monthly amount, billed upfront, first month on signing.
- Rollover policy. Whether unused hours carry over, and for how long.
- Notice period. How much notice either side gives to end it (e.g., 30 days).
- Late fees. A clause so overdue months have consequences — see charging late fees.
Billing upfront matters: charging at the start of the month protects your cash flow and removes the awkwardness of chasing money for work you've already done. If a client does fall behind, the staged reminders in the reminder-email guide handle it calmly.
How do I raise a retainer later?
Review every retainer at least once a year. Two things trigger an increase: your rates have risen (raise new and existing clients, with notice), or the client's needs have quietly grown past the included hours. The annual review is exactly the moment to re-scope rather than keep silently absorbing the extra — and to apply the same logic as raising your rates generally: give notice, anchor the increase to results, and quote new clients the new number immediately.
Frequently asked questions
How do I price a monthly retainer? Hourly floor × realistic monthly hours + margin. A $75 floor over 20 hours is $1,500, before any premium for priority or value.
How many hours should it include? Only what you can reliably deliver, stated explicitly. Cap it and bill overage at a set rate.
Why do retainers become a pay cut? Scope creep — 20 priced hours drift to 30 unpaid ones. Cap hours and track your time to prevent it.
Should hours roll over? Usually no, or only a small amount that expires after a month — never unlimited banking.
Should it be paid upfront? Yes — at the start of each month, first month on signing, to protect cash flow.
What goes in the agreement? Scope, included hours, overage rate, rollover policy, fee and upfront terms, notice period, and late fees.
Retainer vs hourly? Hourly bills time after the fact; a retainer is a fixed upfront fee for a capped scope that smooths income and rewards efficiency.
How do I raise it? Review yearly, give notice, tie it to results or growing scope, and charge new clients the new rate first.
Conclusion
A monthly retainer is one of the best things a freelancer can build — predictable income, a steady client, and a reason to stop chasing the next project every few weeks. But it only works if you price it like a product, not a favour. Start from your floor, decide what it's worth, and then do the unglamorous thing that actually protects it: cap the hours, track your time, and charge for the overage.
Get that right and a retainer becomes the foundation of a stable freelance income. Get it wrong — leave the hours open and never look at the clock — and the most reassuring number on your invoice becomes the one quietly paying you the least per hour.
