Working out your freelance hourly rate is one of those tasks that sounds simple until you actually sit down to do it. Most new freelancers either copy what a friend charges or pluck a number out of thin air — and both approaches usually end in the same place: too much work for too little money. The good news is that there’s a straightforward method that takes about twenty minutes, and once you’ve done it, you’ll never have to guess again.
I’ve watched plenty of talented designers, writers and developers burn out in their first year, not because they lacked skill but because they priced themselves into exhaustion. Getting your rate right isn’t about being greedy. It’s about building a business that can actually survive.
Start With What You Need to Earn, Not What You Want to Charge
Forget market rates for a moment. The most honest starting point is your own finances. Add up what it costs to run your life for a year: rent or mortgage, bills, food, transport, insurance, holidays, and a pension contribution if you’re sensible. Let’s say that comes to £30,000 — a fairly modest figure for much of the UK.
Now add your business costs on top. As a freelancer you’ll be paying for your own equipment, software subscriptions, professional indemnity insurance, accountancy fees, and time spent on admin that nobody pays you for. A realistic allowance is £3,000 to £5,000 a year, depending on your trade. That brings your target to roughly £34,000.
Then there’s tax. As a sole trader you’ll pay income tax and National Insurance through Self Assessment, and you should set aside around 25–30% of your profit for HMRC. That means to take home £34,000 you need to invoice roughly £45,000 a year. This is the figure everything else is built on.
How Many Hours Can You Actually Bill?
Here’s where most people go wrong. A full-time employee works about 260 days a year, but you won’t be billing anything close to that. Take off weekends, then subtract:
- Holidays: 25 days (you deserve at least as many as an employee gets)
- Bank holidays: 8 days
- Sick days: 5 days as a buffer
- Admin and marketing: at least one day a week — pitching, invoicing, chasing payments, doing your accounts
That leaves around 175–185 genuinely billable days. At 7 hours a day, you’re looking at roughly 1,250 billable hours per year. Divide your £45,000 target by 1,250 and you get £36 an hour. That’s your baseline freelance hourly rate — the number below which you’re effectively working for less than you need.
The Simple Formula for Your Freelance Hourly Rate
Put it all together and the maths looks like this:
- Annual target income (living costs + business costs + tax buffer)
- ÷ Billable hours per year (working days minus holidays, admin and downtime)
- = Your minimum hourly rate
Let’s run a second example quickly. Say you’re a copywriter in Manchester who needs £28,000 to live on, spends £2,500 on business costs, and needs to invoice £40,000 after the tax buffer. With 1,250 billable hours, your floor is £32 an hour. If you can realistically only bill 1,000 hours because you spend more time finding clients, your floor rises to £40.
Notice how the number moves. That’s the point: your rate is personal. It reflects your costs, your capacity and your market — not someone else’s.
Adjusting Your Rate for Reality
Your calculated floor is a starting point, not your final price. A few adjustments are worth making:
Round up, not down. If the maths says £37, charge £40. Clients respond better to clean numbers, and the extra margin covers the jobs that run over.
Charge more for short or awkward work. A two-hour job still costs you admin time, emails and context-switching. Many freelancers set a minimum project fee — say £150 — regardless of how quickly they finish.
Review every six to twelve months. Your costs rise, your skills improve, and demand shifts. If you’re fully booked for three months running, that’s the market telling you your rate is too low. A 10% rise is entirely normal; existing clients will usually accept it if you give them a month’s notice.
Consider day rates. Some clients prefer them, and a day rate of 7× your hourly figure is standard. Just be clear about what a “day” means in your freelance contract so nobody expects a 12-hour shift.
Common Pricing Mistakes to Avoid
The classic error is charging what you’d earn per hour as an employee. A £15-an-hour salary is worth roughly £30 an hour freelance once you factor in holiday pay, sick pay, pension contributions and employer National Insurance that you now cover yourself. Doubling your old salary’s hourly equivalent is a decent rule of thumb, not a coincidence.
Another trap is racing to the bottom on platforms like Upwork or Fiverr. Competing on price against the whole world is a losing game. You’re better off specialising — “email copywriter for fintech startups” beats “freelance writer” every time — and charging for the value you deliver rather than the hours you spend.
Finally, don’t apologise for your rate. Quoting confidently and briefly (“My rate is £45 an hour”) signals professionalism. Long justifications invite negotiation you don’t want.
Where Tax Fits Into Your Freelance Hourly Rate
If you’re new to self-employment, the tax side can feel intimidating, but the basics are manageable. Register as a sole trader with HMRC, keep records of every invoice and expense, and file a Self Assessment return each January. Many freelancers put 25–30% of each payment straight into a separate savings account so the tax bill never comes as a shock.

The Takeaway
Calculating your freelance hourly rate comes down to honest maths: what you need to earn, divided by the hours you can truly bill. Do it once, write the number down, and treat it as your floor — then adjust for experience, demand and the value you bring.
