Sarah is a graphic designer in Leeds. Two years ago she left a job that paid £38,000 a year and started freelancing. She did the maths the way most new freelancers do it. She divided her old salary by 2,080, which is 52 weeks multiplied by 40 hours, and she arrived at £18 an hour. It felt fair. It felt safe. Within six months she was working longer hours than she had in her old job and keeping far less money. If you are searching for how to calculate your hourly rate as a freelancer UK, this guide gives you the method that Sarah wishes she had used on day one.
The problem was not her talent and it was not her clients. The problem was the sum itself. Dividing a salary by 2,080 hours pretends that every hour you work is an hour a client pays for, and it pretends that tax, software, holidays and quiet weeks cost nothing. Neither of those things is true. A freelancer pays for all of it out of the same hourly rate, so the rate has to carry far more weight than an employee hourly wage ever does.
This guide works through a simple formula in plain English, with a worked example based on a take home target of £45,000. You will learn how to count your real billable hours, how to build income tax and National Insurance into your rate, which expenses to include, and how to turn the result into day rates and fixed prices. The figures in this guide are estimates to show you the method, and tax rates and allowances can change, so check the final numbers with an accountant for your own situation.
How to Calculate Your Hourly Rate as a Freelancer UK: The Simple Formula
The formula is easy to remember once you see it. Add up everything your business needs to earn in a year, then divide that total by the number of hours clients actually pay for. The four parts of the yearly total are your take home target, your income tax and National Insurance, your business expenses, and your pension and time off cover.
- Take home target: the pay you want to keep after tax
- Income tax and National Insurance: what HMRC takes from your profits
- Business expenses: the running costs of your freelance business
- Pension and time off cover: the benefits an employer used to provide
Dividing by billable hours is the part that changes everything. Most freelancers can bill for only about two thirds of the hours they work. The rest goes on admin, marketing, quotes, learning and chasing invoices. When you divide by the smaller number of billable hours, the rate rises to a level that can actually support you.
Start with the pay you want to keep
Begin with the amount you want left in your pocket after tax, not with your old salary. Your old salary was a gross figure, and your employer also paid pension contributions, holiday pay and sick pay on top of it. Your freelance rate has to replace all of that. In our worked example the target is £45,000 of take home pay. That is the amount Sarah wanted to keep each year, and it is the starting point for every number that follows.
Choose a target that reflects your real life. Add up your rent or mortgage, bills, food, transport, savings and the cost of the life you want to live. If the number feels high, that is useful information. It tells you what your business must earn, and it stops you from setting a rate that quietly leaves you short every month.
Add tax and National Insurance
Tax is not an afterthought for a freelancer. It is one of the largest costs in the business, and it has to sit inside the rate from the start. In the United Kingdom most freelancers register as sole traders and pay tax through Self Assessment. The tax year runs from 6 April to 5 April, and you report your profit, which is your income minus your allowable business expenses.
For the 2026/27 tax year the Personal Allowance is £12,570, which means the first £12,570 of profit is free of income tax for most people. Profits above that are taxed at 20 percent up to £50,270, then at 40 percent above £50,270. You also pay Class 4 National Insurance at 6 percent on profits between £12,570 and £50,270, and at 2 percent on profits above £50,270. Class 2 National Insurance no longer has to be paid when your profits are above £12,570, although you still build up qualifying years towards the state pension.
Working from a take home target of £45,000, the combined income tax and National Insurance bill comes to about £13,000. That figure is an estimate, and your exact bill depends on your personal circumstances, so treat it as a planning number rather than a promise. The important point is the size of it. Tax and National Insurance add almost £13,000 to the revenue your business must earn before you have paid for a single software subscription.
Add business costs
Every freelancer has running costs, even a writer working from a kitchen table. Software subscriptions, a laptop, a phone, broadband, travel to clients, training, insurance and accountancy fees all come out of your revenue. In our example these costs add up to £4,800 a year, which is £400 a month. Some months will be higher and some will be lower, but £400 a month is a realistic average for a freelancer who works online and meets clients in person from time to time.
Keep a simple record of every business cost as it happens, with receipts saved in one place. Good records make your Self Assessment return far easier, and they stop small costs from slipping through unnoticed. If you want a practical system for this, read our guide to tracking business expenses as a freelancer in the UK.
Add pension and time off cover
An employee gets paid holidays, sick pay and pension contributions without thinking about them. A freelancer gets none of that unless the rate pays for it. Our example sets aside £5,200 a year for pension contributions and time off cover. That pot pays for four weeks of holiday, a few sick days, and a regular monthly payment into a pension.
Four weeks away from client work is not a luxury. It is the minimum most people need to stay sharp and avoid burnout across a full year. If you plan for no holiday at all, you will either take the time anyway and lose the income, or you will work through the year without a break and pay for it in other ways. Building the cost into your rate means a holiday is already paid for before you book it.
Divide by billable hours, not working hours
Here is the full worked example with the numbers we have built up so far.
- Take home target: £45,000
- Income tax and National Insurance: about £13,000
- Business expenses: £4,800
- Pension and time off cover: £5,200
- Total revenue needed: £68,000
- Billable hours in the year: 1,100
- Hourly rate: £68,000 divided by 1,100 equals £61.82, rounded to £62
Compare that with the old method. Dividing a £45,000 salary by 2,080 hours gives £21.63 an hour. At £22 an hour and only 1,100 billable hours, yearly revenue would be £24,200, and after tax and costs the amount kept would be under £19,000. That is less than half of the £45,000 target. Sarah was not charging a little too little. She was charging less than a third of the rate her business actually needed.
Billable Hours: How to Work Out Yours
Your billable hours are the hours a client pays for. Everything else is work you do for free, and there is a lot of it. Answering enquiries, writing quotes, meeting new clients, keeping records, marketing, learning new tools and chasing late invoices all take time, and none of it appears on an invoice.
A realistic way to work out your number is to start with your working year. Take 52 weeks and remove four weeks for holidays and bank holidays, which leaves 48 working weeks. At 35 hours a week that is 1,680 working hours. Now remove the time that clients never pay for. For most freelancers that is about a third of the working week, which leaves around 1,100 billable hours. That is the number used in our worked example, and it is a sensible starting point for a full time freelancer.
If you work part time, adjust the same method. Twenty hours a week for 48 weeks is 960 working hours, and two thirds of that is about 640 billable hours. The formula still works. You simply divide your yearly total by a smaller number of hours, which pushes your hourly rate higher. That is correct, because a part time freelancer has fewer hours to spread the same yearly costs across.
Track your time for two to four weeks before you set your rate. Write down every working hour and mark it as billable or not billable. Most people are surprised by the result. The admin and marketing share is almost always larger than they guessed, and seeing the real split makes the rate feel less like a guess and more like a fact.
Income Tax and National Insurance in Plain English
Tax confuses new freelancers because it arrives in large sums and at awkward times. Under Self Assessment you usually pay your tax bill by 31 January after the tax year ends, and you may also pay Payments on Account, which are advance payments towards the next year. That means a good year can be followed by a large bill, and an unprepared freelancer can be caught short.
The simplest defence is to set money aside every time you are paid. A common rule of thumb is to move 25 percent to 30 percent of every invoice into a separate savings account the day the money arrives. That pot covers income tax and National Insurance for most freelancers earning up to around £50,000 of profit. When the tax bill arrives, the money is already there. When the bill is smaller than expected, the leftover amount is a welcome bonus rather than a hole in your budget.
Keep your business money separate from your personal money, even as a sole trader. A separate bank account makes it easy to see what the business has earned, what tax is owed, and what you can safely pay yourself. It also makes your records far cleaner if HMRC ever asks questions. Your accountant can confirm the exact rates that apply to you, and it is worth paying for an hour of advice in your first year so the numbers are right from the start.
Business Expenses Most New Freelancers Forget
New freelancers usually remember the big costs, such as a laptop, and forget the small ones that add up across a year. Software is the classic example. A design tool, a project tool, cloud storage and an invoicing tool can easily cost £60 to £100 a month between them. A phone contract, a share of broadband, travel, printing, training courses, professional insurance and accountancy fees belong on the same list.
Home working costs count too. If you use a room in your home as an office, you can claim a fair share of heating, electricity and broadband under the HMRC rules. Keep the claim simple and honest, and keep records that show how you worked it out. Small costs matter because they reduce your taxable profit, which reduces your tax bill. A freelancer who records £4,800 of expenses pays noticeably less tax than one who records only the obvious items and forgets the rest.
Review your expenses every three months. Cancel tools you no longer use, question subscriptions that have crept up in price, and check whether a yearly plan would cost less than paying month by month. The goal is not to spend as little as possible. It is to know exactly what the business costs, so the rate you charge covers those costs with room to spare.
Holiday, Sickness and Pension: The Cover Employees Get Free
Ask an employee what their job is worth and they will name their salary. Ask again and they will add four weeks of paid holiday, sick pay, pension contributions and bank holidays. Those benefits are worth thousands of pounds a year, and a freelancer has to buy every one of them out of the hourly rate. That is why a freelance rate that matches an old hourly wage is always too low.
Start with the pension. There is no employer adding money to your pension when you work for yourself, so the habit has to come from you. A regular monthly payment, even a modest one, builds up over the years, and pension contributions can also reduce your tax bill. Set the payment to leave your account on the same day each month, just like a salary deduction, so it happens without a decision every time.
Next, plan for sickness. A freelancer who cannot work does not get paid, which makes an emergency fund essential. Aim to build up three months of essential spending in a separate savings account. That fund turns a broken laptop or a week of flu from a crisis into an inconvenience. It also gives you the confidence to turn down work that pays too little, because you are not desperate for the next invoice.
Day Rate Versus Hourly Rate Versus Fixed Price
Your hourly rate is the foundation, and day rates and fixed prices are built on top of it. A day rate is simply your hourly rate multiplied by the hours in your working day. At £62 an hour, a day of seven and a half hours is worth £465. Many freelancers round that to a tidy £450 or £465 and quote it as a day rate for clients who want a full day of work. The client gets a simple number, and you get a rate that still covers tax, costs and time off.
A fixed price works the same way. Estimate the hours a project will take, multiply by your hourly rate, and add a buffer of 10 percent to 20 percent for changes and extra rounds of feedback. If a project should take 20 hours at £62, the fixed price starts at £1,240, plus the buffer. The buffer is not greed. It is payment for the risk you take when you agree a price before the work is fully defined. If you also sell templates, guides or other digital products, the same pricing logic applies, and our guide to pricing digital products for beginners walks through it in detail.
Scope creep is the biggest threat to fixed prices. A project that starts as a five page website can grow into extra pages, extra revisions and extra meetings if nobody sets a limit. Agree the scope in writing before you start, list what is included, and state what counts as extra work. Clear limits protect both sides, and our guide to setting boundaries with clients shows how to put those limits in place without sounding difficult.
How to Raise Your Rate Without Losing Clients
Your rate is not fixed for life. Review it every six to twelve months, and raise it when your skills, your demand or your costs have grown. Most freelancers wait far too long. They charge the same rate for three years while rent, software and living costs rise around them, and then they need a large jump that shocks their clients. Small regular rises are far easier for everyone.
Tell existing clients in good time, in plain language, and give them a start date for the new rate. A short email works well. Thank them for the work you have done together, state the new rate, and name the date it starts. You do not need a long explanation, and you do not need to apologise. Clients who value your work expect your prices to move over time, just as their own costs do.
New clients should always pay the new rate from the first project. There is no need to offer your old rate to win work, and doing so only creates a client who expects the lower price for ever. If a client cannot afford your rate, that is useful information. It tells you to find clients whose budgets match the value you provide, rather than reshaping your business around the lowest payer in the room.
Five Mistakes That Keep Freelance Rates Too Low
- Copying a competitor rate without knowing their costs, their hours or their take home target. Their number tells you nothing about your business.
- Forgetting the hours that clients never pay for. Admin, marketing and quotes are real work, and the rate has to carry them.
- Pricing from fear instead of from maths. A rate set to avoid losing a client is almost always too low, and it leaves you working hard for too little.
- Never raising the rate. A rate that stays still for years falls behind in real terms, even if the number on the invoice never changes.
- Quoting a fixed price before the scope is agreed. Extra work that was never priced will eat the profit out of the whole project.
Your Rate Is a Floor, Not a Ceiling
Learning how to calculate your hourly rate as a freelancer UK is the starting point, not the finish line. The number you arrive at is the lowest rate your business can afford, and it is the floor for every quote you send. Day rates, retainers and fixed prices all grow out of it, and every one of them should be checked against it before you agree to the work.
Work through the formula once with your own numbers. Set a take home target that covers your real life, add tax and National Insurance, add your business costs, add pension and time off cover, and divide by your real billable hours. Then charge that rate with confidence. If the number surprises you, trust the maths. It is showing you what your business needs, and it is the difference between freelancing as a hobby and running a business that pays you properly. Remember that the figures in this guide are estimates to explain the method, so check your own numbers with an accountant before you rely on them.
Frequently Asked Questions
How many billable hours should I plan for each year?
Most full time freelancers can bill for about 1,000 to 1,200 hours a year. Start with 48 working weeks at your usual weekly hours, then remove about a third for admin, marketing and other work that clients never pay for. Track your time for a few weeks to check the split against your real working pattern.
What percentage should I set aside for tax?
Set aside 25 percent to 30 percent of every payment you receive, and keep it in a separate savings account. That pot usually covers income tax and National Insurance for profits up to around £50,000. Your exact bill depends on your profit and your Personal Allowance, so an accountant can give you a precise figure.
Should I charge an hourly rate or a day rate?
Use your hourly rate to work out the day rate, then quote whichever suits the job. Multiply your hourly rate by seven and a half hours for a standard day. Day rates suit longer bookings, while hourly rates suit small tasks and open ended work where the total time is hard to predict.
How do I price my work when I am just starting out?
Work through the same formula with honest numbers, even if the result feels high. A lower starting rate is fine while you build experience, but set a date to review it, and raise it as your skills and demand grow. Charging far below the formula rate for too long trains clients to expect cheap work and leaves you unable to cover your costs.
When should I raise my hourly rate?
Review your rate every six to twelve months. Raise it when your costs rise, when you learn new skills, when demand for your work grows, or when you are turning work away. Give existing clients notice in writing, name the start date, and apply the new rate to all new clients straight away.
