How do I calculate my freelance hourly rate in the UK?

Start with the annual net income you want to take home. Work backwards through income tax, Class 4 National Insurance (8% on profits between £12,570 and £50,270 in 2024/25, then 2% above that), overhead costs, and pension contributions to find the gross income you need. Then divide by realistic billable hours — not 2,080. A good estimate for UK freelancers is 46 weeks multiplied by 30 billable hours, which gives 1,380 hours per year. Divide your required gross by 1,380 and you have your hourly rate.

What is a realistic freelance day rate in the UK?

Day rates vary enormously by sector and experience, but UK market benchmarks as of 2025–26 are roughly: junior developer £350–450/day, senior developer £600–900/day, designer £300–500/day, copywriter £300–600/day, project manager £350–550/day. If your calculated rate — based on what you actually need to earn — sits above these ranges, you need to either reduce costs or build a portfolio that justifies a premium.

Why should I use 1,380 billable hours instead of 2,080?

2,080 hours assumes you bill every working hour of every week all year. In reality, UK freelancers take holiday, have sick days, observe bank holidays, spend time on admin, business development, invoicing, proposals, and networking — none of which clients pay for. Using 46 working weeks (allowing 6 weeks for holiday, illness, and bank holidays) and 30 billable hours per week (not 40) gives 1,380 hours: a much more honest estimate of what you'll actually invoice.

Do I need to add VAT on top of my freelance rate?

If your taxable turnover exceeds £90,000 in a rolling 12-month period (the 2024/25 VAT registration threshold), you must register for VAT and add 20% to your invoices. You then pay that VAT over to HMRC quarterly. This is not extra income — it belongs to HMRC. Your net rate stays the same; VAT is collected on behalf of the government. Factor this into client conversations early, as it affects their budget.

How often should I review my freelance rate?

At least once a year. Software subscriptions, accountancy fees, insurance premiums, and your own cost of living all increase over time. If your rate stays flat while your costs rise, your effective take-home shrinks. Many freelancers are too nervous to raise rates with existing clients, but a small annual increase — framed as a business review rather than a demand — is far easier than staying flat for three years and then needing a 30% jump.

How Freelancers Should Calculate Their Hourly Rate (Most Undercharge)

Dividing your old salary by 52 weeks and 40 hours gives you a number that sounds reasonable and loses you money every single month. Here's the formula that actually works, with worked numbers for UK freelancers.

7 April 2026

By Krishna Chaitanya, Software Engineer

A designer goes freelance after eight years in-house on a £45,000 salary. She does the maths: £45,000 divided by 52 weeks, divided by 40 hours, equals £21.63 an hour. Seems reasonable -- that's what she was worth to her employer, after all. So she quotes £22 per hour and feels good about it.

Three months later, she's not feeling good. The tax bill is approaching. There's no pension building up. The laptop needed replacing. The accountant charges £800 a year. There were two weeks between contracts where nothing came in. And the six hours a week spent on proposals, admin, and chasing invoices? Nobody paid for those. On paper she worked 40 hours a week. On paper she invoiced 40 hours a week. In reality, she's taking home less than when she had a salary, without the holiday pay, the sick pay, or the job security.

This is the most common mistake freelancers make, and it happens because the salary-to-hourly conversion looks logical but leaves out almost everything that matters.

The Real Problem

When you were employed, your employer was paying more than your salary to keep you. Employer National Insurance runs at 13.8% on earnings above £9,100 -- on a £45,000 salary, that's roughly £4,950 on top of what you saw on your payslip. Your employer was likely contributing to a workplace pension (typically 3--5% of your salary). You got paid annual leave: 28 days minimum in the UK. Sick days. Equipment. Software licences. Training budget. Often a phone, sometimes a laptop.

None of that came out of your salary. It came out of the total cost of employing you.

As a freelancer, all of those costs come out of your rate. There is no employer picking up NI, no company pension contribution, no paid holiday. When you're ill for a week, no money comes in and no money goes out -- you absorb the loss entirely. When you take two weeks off in August, you're paying for it yourself.

This is not a reason to avoid freelancing. It is a reason to price yourself correctly. Undercharging doesn't just reduce your earnings -- it means you are actively subsidising your clients.

The Correct Formula

The right starting point is your target net income: the actual amount you want in your bank account after tax. Work backwards from there.

Step 1: Calculate your tax liability

On 2024/25 rates, the picture for a sole trader looks like this:

Income tax: 0% on the first £12,570 (personal allowance), 20% on £12,571--£50,270, 40% above that
Class 4 National Insurance: 8% on profits between £12,570 and £50,270, then 2% above that
Class 2 National Insurance: now voluntary following 2024 changes, but many freelancers continue to pay £3.45/week to protect their State Pension entitlement

Add your estimated tax and NI to your target net income. That sum is the gross profit your business needs to generate before any overheads.

Step 2: Add overhead costs

Think through every business cost: accountancy fees (typically £500--£1,500/year for a sole trader), professional indemnity insurance, software subscriptions (Adobe, Microsoft 365, project management tools), a contribution towards equipment depreciation, phone costs, any co-working space. A conservative total for most freelancers is £2,500--£4,500 per year. These are real costs that come out before you see a penny of income.

Step 3: Add pension contributions

You are now your own employer. If you want a pension, you pay for it. A reasonable target is 5--10% of your gross income.

Step 4: Calculate realistic billable hours

This is where most freelancers make their second mistake. Start with 52 weeks, subtract 6 (4 weeks holiday, 1 week illness, 1 week bank holidays) and you get 46 working weeks. Then take 40 hours a week, subtract roughly 10 hours of admin, business development, invoicing, and proposals -- none of which clients pay for -- and you get 30 billable hours per week.

46 weeks x 30 hours = 1,380 billable hours per year.

Step 5: Calculate your rate

Hourly rate = (target net income + tax + NI + overheads + pension) / 1,380

This is the number you should be quoting, not your old hourly salary equivalent.

How the Freelancer Rate Calculator Helps

Running all of this by hand is possible, but it is easy to miss items or get the tax calculation wrong. Our Freelancer Rate Calculator does the full calculation automatically.

You enter your target take-home income, your location (the calculator handles UK tax bands), your overhead costs, your pension contribution percentage, and the number of billable weeks and hours you realistically expect to work. It handles income tax and National Insurance using current UK rates.

The output gives you both an hourly rate and a day rate (based on an 8-hour day), which is the figure most UK clients -- especially in tech, design, and professional services -- prefer to see on a proposal. You can adjust inputs in real time to see how changing your holiday allowance or overhead costs affects what you need to charge.

If you are about to go freelance, or you have not reviewed your pricing in over a year, running these numbers takes about two minutes and may save you from months of undercharging.

A Worked Example

Scenario: A copywriter wants to take home £40,000 per year after tax.

Tax and NI calculation (2024/25):

Income tax: £0 on first £12,570 + 20% on the band above that
To net £40,000 you need approximately £50,000 gross before tax and NI
Class 4 NI: 8% on £37,700 (the band between £12,570 and £50,270) = £3,016
Total tax + NI: approximately £10,500

Overheads: £3,600/year (accountant £900, insurance £600, software £900, equipment fund £600, phone £600)

Pension: £2,400/year (roughly 5% of gross)

Total gross income needed: £40,000 + £10,500 + £3,600 + £2,400 = £56,500

Hourly rate: £56,500 / 1,380 = £40.94/hour

Day rate (8 hours): £40.94 x 8 = £327.50/day

Compare that to the £21.63/hour the person in the introduction was quoting. The gap is £19.31 per hour, or over £150 per day. Over 1,380 billable hours a year, quoting the lower rate means leaving £26,647 on the table. Not because clients refused to pay more. Because the freelancer never asked.

What to Do With the Result

Once you have your calculated rate, the next question is whether the market will bear it. There is no point setting a rate you cannot actually charge.

UK market benchmarks by sector (2025--26 figures):

Junior developer: £350--450/day
Senior developer: £600--900/day
Designer: £300--500/day
Copywriter: £300--600/day
Project manager: £350--550/day

If your calculated rate sits comfortably within your sector's range, start quoting it. If it is above market, you have a real decision: either reduce your target take-home or overhead costs to bring the rate down, or build a portfolio and track record that justifies a premium. Clients pay above-market rates for specialists, for speed, and for reliability. Generalists rarely get away with it.

One thing worth setting up regardless of where your rate lands: an emergency fund of 3--6 months' essential expenses. Freelancing means income gaps are inevitable -- a contract ends, a client delays a project, a slow patch arrives. Without a runway, you end up dropping your rate out of desperation to fill the calendar. Use our Savings Goal Calculator to work out the monthly amount you need to build that buffer.

Common Mistakes

Not building in holiday pay. When a salaried employee takes two weeks off, they still get paid. When you take two weeks off, nothing comes in. Every week of holiday you take is a week where your annual billable hours drop -- which is why we use 46 working weeks, not 52. Try to squeeze 52 weeks of billing out of yourself and you either burn out or take no holiday at all. Neither works.

Forgetting VAT if you are near the threshold. If your annual turnover is approaching £90,000 (the 2024/25 registration threshold), you need to factor VAT into your pricing strategy. Once you are VAT-registered, you add 20% on top of your net rate on invoices to VAT-registered clients. That 20% is not yours -- it goes to HMRC every quarter. Treating VAT money as income is a fast route to a nasty surprise when the return is due.

Not reviewing the rate annually. Your accountant charges more this year than last year. Software prices go up. Inflation eats into your effective take-home. A rate that was right in 2023 may be quietly losing you money by 2026. Review your numbers every January, recalculate what you need to charge, and adjust. A 5% increase each year is a much easier conversation with clients than a 25% jump after four years of staying flat.
