Most freelance rates are set by reconnaissance: look at what others charge, pick the middle, adjust for nerve. The method produces a number that feels market-tested and is in fact arbitrary in the only way that matters — it was computed from somebody else's life. Their rent, their tax band, their appetite for holidays, their proportion of unpaid admin: all of it is baked into the rate you copied, and none of it is yours.
The alternative is to build the rate backwards from your own year. Decide the income you need to keep. Add the costs of being in business. Reserve for tax before the tax authority asks. Divide by the hours you can genuinely sell — the step where honesty is hardest, because the denominator is smaller than anyone wants it to be. The result is not a price; it is a floor, below which the arithmetic of your year does not work, and knowing your floor changes every negotiation you will ever have.
This article builds one rate completely, with unglamorous numbers, then deals with the two questions that follow: why the billable-hours figure is the whole battleground, and how a floor relates to the price you actually quote for a given piece of work.
The build, with real-shaped numbers
Target income to keep: 60,000 — the amount the year must leave in your hands after business costs and tax, for rent, life and saving. Business overheads: 6,000 for software, insurance, equipment, professional fees and the accountant. Together they require 66,000 after tax. Reserving 20% for tax means the practice must bill 66,000 ÷ 0.8 = 82,500, because a fifth of everything invoiced is spoken for before it arrives.
Now the denominator. Work 47 weeks — five weeks off for holiday, illness and the gaps life inserts. Five days a week, eight hours a day: 1,880 working hours. Of those, the share a client pays for: 60%, a realistic figure for an established practice once proposals, marketing, admin, invoicing and fallow gaps between engagements are counted. Billable hours: 1,128. The floor rate is 82,500 ÷ 1,128 ≈ 73 an hour — a day rate near 585. Below that line, this particular life does not fund itself. Note how ordinary the inputs were: no courage was required, only arithmetic and the refusal to round the inputs in your own favour.
The billable share: where rates are really decided
Every input moves the rate, but the billable share moves it like a lever. At 100% billable — the fantasy denominator of every new freelancer's first spreadsheet — the same practice needs only 44 an hour. At 50%, it needs 88. The difference between those years is not pricing skill; it is whether the unpaid work of running a practice gets funded by the paid work, or quietly by the freelancer's evenings and eventual burnout.
Estimate your share from evidence where you can: track a month, or reconstruct one from your calendar, sorting hours into client work and everything else. New practices usually run lower — business development is unpaid and heavy early on — which argues for a higher floor rate precisely when the market feels hardest to charge it to. That tension is real and does not disappear for being named. What naming it does is relocate the problem: if the floor rate is unchargeable, the levers are the inputs — lower overheads, a lower target for a season, a niche where the work commands more — rather than the pretence that 100% of hours can be sold.
Floor versus price: what the number is for
The floor is not the quote. Clients pay for skill, scarcity, speed and outcomes; a specialist whose work prevents an expensive mistake prices the prevented mistake, not the hour. Quoted prices should float above the floor by whatever the market and the value support — and the floor's job is to make the floating conscious. Work you accept below the floor is a subsidy you are giving the client, sometimes with good strategic reason — a portfolio piece, a doorway into a sector — but a subsidy whose size you should know in money, not discover in December.
The floor also disciplines the two classic slow leaks. Scope creep: the “small extra” on a fixed fee is unpaid time drawn against your billable pool, and ten small extras a month is a rate cut nobody approved. Discount requests: 10% off is not a gesture, it is a computed number of additional billable hours you must find this year to stand still — the floor converts politeness into arithmetic, where it can be judged. Revisit the build annually, because every input creeps: overheads rise, tax bands move, the target that funded last year's life no longer funds this one's, and a rate three years unreviewed is usually a pay cut you awarded yourself.
Key takeaways
- Build the rate backwards: (target income + overheads), grossed up for tax, divided by genuinely billable hours.
- Billable hours = working weeks × days × hours × billable share. The share — 50–65% for most established practices — is the decisive input.
- Costing at 100% billable produces a rate roughly half the honest one, funded later by evenings and burnout.
- The result is a floor, not a price: quote above it by value where you can, and know in money the size of any concession below it.
- Review the build annually — a rate that never moves is a pay cut on an instalment plan.
Mistakes to avoid
- Copying a competitor's rate, importing their cost base, tax position and holiday allowance wholesale.
- Dividing by every working hour rather than the billable share, then wondering why a “good rate” produces a bad year.
- Forgetting the tax gross-up — setting a rate that funds the target only if the tax authority agrees to waive its share.
- Giving small extras and discounts off the record, uncounted against the billable pool they consume.
Questions readers ask
My floor rate is higher than my market seems to bear. Now what?
Then the inputs are the agenda, in order: reduce overheads, specialise towards work the market prices higher, or accept a lower target temporarily with a date on it. What not to do is fudge the billable share until the spreadsheet agrees with your hopes.
Should I quote hourly or by the day?
Quote in the unit the client budgets in, but always know both figures and the conversion between them — a day is not automatically eight billable hours of project work, and clients who buy a “day” and receive six focused hours should know that is the deal in advance.
How do rush jobs and weekends price?
Above the floor by a premium you set in advance — commonly a quarter to a half more — because they consume your scarcest asset, unscheduled time, and displace the recovery the working-weeks figure assumed. A rush premium invented mid-negotiation is a discount waiting to happen.
Put it into numbers
Run your own build — your target, your overheads, your honest billable share — and write the floor down where you negotiate. It is the most useful number a freelancer owns.
