How do I calculate a freelance rate?

Add your target take-home income to your annual business expenses, then divide by the days or hours you can realistically bill in a year. That result is your minimum sustainable rate — the floor your pricing must clear before you adjust for complexity, risk or market position.

How many billable hours or days should I assume?

Start from 260 working days, remove holiday, sick and admin days, then assume only 60–75% of what remains is billable. For most solo UK freelancers that lands around 130–160 billable days, or roughly 1,000–1,200 billable hours per year.

How do business expenses affect my rate?

Expenses are recovered through your rate, not paid out of your income. Software, insurance, hardware, accountancy, training and travel all get added to your income target before you divide by billable time, so a £5,000 cost base on 140 billable days adds about £36 to every day rate.

What counts as non-billable time in a pricing model?

Sales calls, proposals, invoicing, bookkeeping, marketing, professional development and unpaid revisions. It is real work that keeps the business running, so it belongs in the divisor of your pricing calculation rather than being ignored.

How often should I review my rate?

Review the whole calculation at least once a year, and sooner whenever your expenses, utilisation or positioning change materially. Rebuild the model from current numbers rather than adding an arbitrary percentage to last year's rate.

Why freelance pricing needs a method

There is no HR department setting your salary and no pay scale to reference. As a freelancer you fund your own tax, National Insurance, pension, insurance, software, equipment and holidays, and you spend a large share of the year on work you cannot invoice. A method that starts from those costs produces a rate you can explain and hold; guessing produces a rate you quietly resent.

Step 1 — Define your target income

Start with what you need to draw personally over twelve months, before tax. Be specific: living costs, pension contributions, savings and a margin for quiet months. This is the number the whole model is built to deliver, so an optimistic figure here quietly underprices everything downstream.

Step 2 — Add your business expenses

List everything the business costs for a year: software subscriptions, hardware, phone and internet, insurance, accountancy, training, travel, coworking and professional memberships. Expenses are recovered through your rate, so they sit alongside your income target rather than coming out of it.

Step 3 — Estimate your working weeks

A calendar year is 52 weeks. Remove holiday, public holidays and an allowance for illness, and most full-time UK freelancers are left with roughly 44–46 working weeks. Decide this before you think about rates — it is a lifestyle decision, not a pricing one.

Step 4 — Estimate realistic billable time

Billable days are the days you actually invoice for. They are not the same as working days:

5 days per week × 52 weeks = 260 working days
Minus 25 holiday days = 235 days
Minus 15 sick and admin days = 220 available days
Only 60–75% of available days are billable = 132–165 billable days

The gap is non-billable time: proposals, sales calls, invoicing, bookkeeping, marketing, learning and unpaid revisions. Price against total working days and you will spend evenings catching up on unpaid admin.

Step 5 — Calculate your minimum sustainable rate

rate = (annual income target + annual expenses) ÷ billable days

Worked through with typical numbers:

Desired annual income before tax: £60,000
Annual business expenses: £5,000
Billable days per year: 140

day rate = (£60,000 + £5,000) ÷ 140 = £65,000 ÷ 140 = £464 per day

At 7.5 billable hours per day that is roughly £62 per hour. This is gross revenue — Income Tax, National Insurance and any VAT come out of it. Many freelancers add a 10–20% buffer for pension, late payment, equipment replacement and development:

£65,000 × 1.15 = £74,750 ÷ 140 days = £534 per day (£71 per hour)

Step 6 — Adjust for complexity and risk

The minimum sustainable rate is a floor, not a price list. Move above it when the work carries more risk or demands more of you:

Scope certainty — vague briefs deserve a premium or a fixed discovery phase
Specialism — scarce, high-impact skills price above generalist work
Commercial value — work tied directly to client revenue supports higher pricing
Timeline pressure — displacing other work has a cost
Payment risk — slow-paying or unfamiliar clients justify deposits or a higher rate

Choosing a pricing model

Once the underlying rate is set, the format is a separate decision. Hourly rates suit small tasks and support work; day rates suit most UK project and consulting work; project rates suit clearly scoped deliverables and reward efficiency, provided you control scope creep. For a full comparison of the first two, read Hourly Rate vs Day Rate (UK).

Check your calculated rate against the UK market

Once you have calculated a sustainable rate, compare it with UK freelance benchmark ranges to check whether the result is commercially realistic. If your floor sits far above typical ranges you may need to cut costs, raise utilisation, specialise or change client segment; far below and you are leaving money on the table.

Use the How much should I charge as a freelancer in the UK? guide for the benchmark answer, and the UK Freelance Rates Dataset for ranges by profession and experience level. Recommended next read: How much should I charge as a freelancer in the UK?

Build in a review process

Costs rise, utilisation shifts and experience compounds. Diary a rate review at least annually, rebuild the calculation from current numbers, and apply the new rate to new clients immediately. When it is time to move existing clients up, follow How to Raise Your Freelance Rates.
