Freelance Day Rate Calculator

Day rate by target income and non-billable time

The rate you need is not your target income divided by the days in the year. It is your income plus overheads, grossed up so that what survives the tax buffer is still the income you asked for, then spread over the days you can actually invoice. The table holds everything steady except the two things people get wrong most often, and the columns show how far the rate has to climb as more of your week disappears into work nobody pays for.

Read along the £45,000 row and the rate rises from £278 to £464 without the income target moving at all. Non-billable time is the most expensive input on the page and the one most often left out. The highlighted case, £45,000 at 25 percent, is the £371.01 the calculator above lands on, or £46.38 an hour across an 8-hour day.

What a day rate you have been offered actually leaves you

The calculator runs from an income target to a rate. A client offer runs the other way, so this table is the same arithmetic backwards. Each row takes a quoted day rate, bills it across 172.5 billable days, then removes the 25 percent tax and buffer reserve and £3,000 of overheads to leave the income you can actually spend.

The gap between the first and last columns is the part that surprises people leaving employment. A £400 day rate reads like a £104,000 year and pays £48,750. The tax and buffer column is a reserve, not a tax bill: your real liability depends on your trading structure and allowances, and the salary take-home calculator runs the PAYE bands if you want to compare against an employed offer.

How many days you can really bill

A calendar year holds about 260 weekdays. Nobody bills 260 of them. UK employees get at least 5.6 weeks of statutory leave including bank holidays, which is 28 days, and a freelancer taking the same amount is down to roughly 232 working days before a single sick day or unpaid pitch. The table turns working weeks and non-billable time into the only number the rate calculation cares about, at five days a week.

Every cell in the top-left corner of this table is a fantasy year: 52 weeks with no holiday and no admin. The realistic band for most established freelancers is the 44 to 48 week rows at 20 to 30 percent non-billable, or roughly 154 to 192 days. Halving your billable days doubles the rate you need, which is why this input moves the answer more than the income target does.

Agency margin: what the client pays against what you get

Agency and marketplace work is quoted two different ways in the same conversation. The charge rate is what the end client pays; the pay rate is what reaches you after the margin comes off the top. The table converts one into the other, so you can check an offer against the rate the tables above say you need.

A £600 charge rate at a 25 percent margin pays £450, which is £150 a day or £25,875 across a full billable year. Margins are negotiable and vary by sector, and they are separate from any umbrella company fee or PAYE deduction on an inside-IR35 engagement, which comes off afterwards.

Why a day rate is not a salary divided by working days

Dividing £45,000 by 260 weekdays gives £173.08, and that number is wrong in four separate directions at once. It bills days you will spend on holiday, sick or chasing work. It ignores overheads. It treats the tax reserve as somebody else's problem. And it quietly deletes the parts of an employment package an employer was funding on top of the salary, which you now fund yourself out of the same rate.

• Paid leave. The statutory minimum for a UK employee is 5.6 weeks including bank holidays. As a freelancer that time is unbilled, which is exactly what the working-weeks input removes.
• Pension. Under auto-enrolment the employer contributes at least 3 percent of qualifying earnings. Matching that yourself is an overhead, not a saving from your income.
• Employer National Insurance. An employer pays this on top of your salary and you never see it on a payslip. It does not disappear when you go freelance, it changes shape.
• Sick pay and gaps between contracts. An unbilled week costs a freelancer the full rate. This is what the buffer half of the tax and buffer input is for.
• Equipment, software, insurance and accountancy. These are the overheads field. Professional indemnity cover and an accountant alone often account for several hundred pounds a year before any hardware.

Put together, that is why the £45,000 row lands near £371 rather than £173.08. The rough doubling is not a markup or a premium, it is the cost of the things the salary was hiding. If you are converting the other way, from an hourly or day figure to an annual salary equivalent, the hourly to salary calculator does the straight conversion without the freelance adjustments.

What this calculator does not decide

The figure it produces is a floor, not a price. It tells you what your own numbers require, which is the answer to a costing question rather than a pricing one. Four things sit outside it:

• What the market pays. If the floor comes out above the going rate for your work, the answer is usually fewer non-billable days or a different type of client, not a rate nobody will accept. If it comes out well below, you are underpricing and the calculator will not tell you so.
• VAT. Once your taxable turnover passes the registration threshold you charge VAT on top of your rate. It does not change what you earn, but it changes the invoice, and a client who cannot reclaim it feels the whole increase. The VAT calculator handles the add-on and the reverse.
• Employment status and IR35. An inside-IR35 engagement has income tax and National Insurance deducted before the money reaches you, so its day rate is not comparable like for like with an outside-IR35 or self-employed rate. Compare what lands, not what is quoted.
• Value-based and fixed-price work. Day rates price your time, which caps your income at hours worked and quietly penalises getting faster. A fixed price for a defined outcome breaks that link. The day rate is still worth knowing, because it is what tells you whether a fixed price was any good.

Revisit the number at least once a year, and any time your overheads, your tax position or your mix of billable work changes. If part of your income comes from commission rather than billed days, the sales commission calculator covers that side.
