How to price a freelance monthly retainer from your hourly floor

Reserved hours × the floor you already set. Add a small unused-hours buffer you type so idle calendar still pays. Overage defaults to the same floor. This is planning math — not a contract, not a tax engine, and not an official “industry standard” percent.

When a retainer beats hourly or a project

Hourly is a meter. A project quote is a finish line. A retainer is a reserved slice of your month. Use it when the work repeats and the client needs you on tap — support, content, ongoing design, fractional ops — not when they need one deliverable with a date.

Set the floor first on how to set a freelance rate or the hub salary → hourly tool. This page does not rebuild tax, utilization, or expenses. It only turns that floor into monthly keep.

The private formula

Retainer = hourly floor × included hours. Optional: add a small unused-hours buffer you type, then retainer = floor × (included hours + buffer hours). Overage, if they blow the cap, defaults to the same floor unless you type a different rate.

The hourly number can stay in your notes. The client sees one monthly fee, what is included, what happens to unused hours, and the overage line. The unused-hours buffer is a planning default you set — not a law, not CPI, and not an official freelance percent.

Worked example: $90/hr × 20h = $1,800/mo

Hourly floor $90. Included hours 20 / month. Unused-hours buffer 0 (you did not add slack on the card). Monthly retainer = 90 × 20 = $1,800. Implied keep is the same $1,800 if they pay and stay inside the cap — cash that still has to clear after whatever processor or marketplace cut you already handle on other pages. This card has no tax engine.

If you type a 2-hour unused-hours buffer, priced hours become 22 and the retainer is 90 × 22 = $1,980. That extra $180 is for reserved-but-idle time you are holding. You chose 2. This page does not treat “10% unused” or any blog “standard retainer discount” as official.

Annual keep at the $1,800 example is $1,800 × 12 = $21,600 if the retainer runs the year and they do not cancel. That is arithmetic, not a forecast.

Unused hours are the product, not a leak

Clients buy a block of you. Some months they use 20 hours. Some months they use 11. If unused hours roll forever, you sold a reservation and then gave the unused slice back as a debt on next month’s calendar. That is how a retainer quietly becomes unpaid overtime.

The hub retainer tab runs the other direction: paste a fee and included hours to see effective hourly if they under-use or over-use. Use it to sanity-check the $1,800 you just priced here.

Overage: the cap has to mean something

When they go past 20 hours, invoice the extra at an overage rate. This card defaults that rate to the same hourly floor if you leave the box blank (here, $90). You can type a higher number if blowing the reserved week costs you other work. There is no official industry multiplier — not 1.25×, not 1.5× — on this page. You set it.

Deposit and start: block the calendar after cash, not after Slack

A retainer is a monthly invoice, not a vibe. Collect the first month in full — or a deposit against it — before you open the channel or hold the hours. Same rule as a project: a promise to pay is not keep. Split and wording live on the freelance deposit guide. You pick the percent; that page’s 50% is a planning default, not a retainer law.

Start after it is in the account. Kickoff decks, unpaid “discovery,” and a week of Slack while they “process the invoice” still spend the hours the $1,800 was built on.

Kill unpaid slack

Slack threads, “quick calls,” extra review rounds, and status pings are hours. If they are not on the cap, they are a discount you did not agree to. Track them against the 20. When the cap is gone, stop or invoice overage. Unpaid slack is the usual way a clean $90 floor dies inside a “light” retainer.

If the client wants unlimited chat for $1,800, that is not 20 hours. Raise the included hours (and the fee) or keep the cap. Do not nod along in the thread and hope the math still works.

When the floor moves, the retainer moves

If costs, billable weeks, or the hub floor went up, the $1,800 is now under water. Recalc the floor, then raise the monthly fee the same way you would raise hourly — one date, one number. The raise a freelance rate guide is the note. Do not grandfather a retainer forever while new hourly clients pay $110.

This page is planning, not a contract

Educational only — not legal or tax advice. We do not invent a required unused-hours percent, a statutory notice period, or “industry standard” retainer discounts as official rules. Confirm live terms in whatever agreement you already use. If you need an enforceable retainer, ask a lawyer in your jurisdiction. The math here is: hourly floor, included hours, an unused-hours buffer you type, optional overage (default = floor), monthly retainer, implied keep.

FAQ

How do I price a freelance monthly retainer from my hourly rate?

Retainer = hourly floor × included hours per month. You can add a small unused-hours buffer you type so reserved-but-idle time still hits the floor. That buffer is a planning default you set, not a law. Overage defaults to the same floor if you leave it blank.

When does a retainer beat hourly or a project quote?

When the work repeats and you want reserved capacity plus predictable keep. Stay hourly or quote a project when the job has a clear end or the hours cannot be capped yet.

What happens to unused retainer hours?

You decide. A common practice is use-it-or-lose-it inside the month so unused hours do not roll into a debt on your calendar. That is a planning choice, not a statute. The client still pays the retainer.

How should I charge overage on a retainer?

Invoice hours past the included cap at an overage rate. This card defaults overage to your hourly floor. You can type a higher number. There is no official industry multiplier on this page.

Should I take a deposit before a retainer starts?

Collect the first month (or a deposit against it) before you block the calendar or open Slack. Start after it clears. Planning only — not legal advice.
