A £40,000 salary sounds clear until you try to compare it with an hourly job, a contract, or a freelance rate. This guide gives you the gross and after-tax hourly figures for the UK in 2026/27, shows the tax arithmetic behind them, and explains why a higher salary on longer hours can pay less per hour.
Search intent: you want to know what £40,000 a year is worth per hour in the UK, before and after tax, so you can compare jobs or set a rate. The headline answer is in the first section below, with the full breakdown, hours table and worked example after it.
How much is forty thousand pounds a year per hour in the UK?
On a standard 37.5 hour week, £40,000 a year is £20.51 an hour before tax, and £16.57 an hour after income tax and employee National Insurance in 2026/27. On a 40 hour week it is £19.23 an hour gross and £15.54 an hour net, because the same salary spreads over more paid hours.
Those four figures are the ones most pages get half right. Template calculators usually show the gross rate only, or quote a net rate with no tax year, no hours basis and no workings. Here both rates carry their basis: 37.5 hours a week is 1,950 paid hours a year, and 40 hours a week is 2,080 paid hours a year. Change the hours and the hourly rate moves, even though the salary does not.
Rates last reviewed: October 2026. Income tax bands are from GOV.UK Income Tax rates and Personal Allowances, and employee National Insurance rates are from GOV.UK rates and thresholds for employers 2026 to 2027. Assumptions throughout: England, Wales or Northern Ireland, standard tax code, no pension contributions, no student loan, no other income.
| Hours basis | Paid hours a year | Gross per hour | After tax per hour |
|---|---|---|---|
| 35 hours a week | 1,820 | £21.98 | £17.76 |
| 37.5 hours a week | 1,950 | £20.51 | £16.57 |
| 40 hours a week | 2,080 | £19.23 | £15.54 |
At £40,000 you are still inside the basic rate band, which runs to £50,270, so every pound above the Personal Allowance is taxed at 20 percent with no higher rate slice. That changes if a rise or bonus takes you past £50,270.
Scotland has different income tax bands, so the after-tax figures differ there. If your main home is in Scotland, read our guide to self-employed tax in Scotland for how the Scottish bands work, and note that employee National Insurance is the same UK-wide.
How do you work out the hourly rate from a salary?
Divide your gross annual salary by the hours you are paid for in a year, which is your weekly hours multiplied by 52. For £40,000 that is 40,000 divided by 1,950 hours on a 37.5 hour week, giving £20.51, or divided by 2,080 hours on a 40 hour week, giving £19.23.
Hourly rate = annual salary divided by (weekly hours x 52 weeks)
The formula is simple. The mistakes sit in the inputs. First, start from gross salary, the figure in your contract, not the amount in your bank account. Second, use your own contracted hours: plenty of UK contracts are 37 or 36.5 hours, not 37.5, and the wrong weekly figure shifts the result by 40p to 60p an hour. Third, keep gross with gross and net with net when you compare.
You can run your own hours and salary through LancerBill’s hourly rate calculator instead of doing the division by hand, and use LancerBill’s rate converter to flip the same salary into weekly and monthly figures. Our general guide to converting salary to hourly pay the right way covers other countries and schedules in more depth, and our sibling guide for £30,000 a year per hour in the UK uses the same method one band down.
Tip: Check your contract, not your rota. If your contract says 37.5 hours but you regularly stay late, your contracted rate is still based on 37.5 hours. The overtime effect is real, but it belongs in the separate worked-hours calculation further down this page.
Worked example: the tax on a forty thousand pound salary in 2026/27
Here is the full arithmetic behind the £16.57 net hourly figure, so you can check every line against your own payslip. Salary: £40,000. Tax year: 2026/27.
Step 1: Income tax. The standard Personal Allowance is £12,570, so you pay no tax on the first £12,570. The rest, £40,000 minus £12,570, is £27,430. All of it sits inside the basic rate band, which runs to £50,270 at 20 percent, per GOV.UK. Tax is £27,430 x 0.20 = £5,486.00.
Step 2: Employee National Insurance. This is Class 1, the employee class, charged at 8 percent on earnings between £12,570 and £50,270 a year, per GOV.UK. The slice is the same £27,430. National Insurance is £27,430 x 0.08 = £2,194.40. Note the rate: employees pay 8 percent, not the 6 percent Class 4 rate that sole traders pay. Mixing those two rates is the most common error in take-home articles.
Step 3: Take-home pay. £40,000 minus £5,486.00 minus £2,194.40 = £32,319.60 a year. That is £2,693.30 a month, £621.53 a week and £124.31 a day across 260 working days.
Step 4: Net hourly rate. On a 37.5 hour week: £32,319.60 divided by 1,950 = £16.57 an hour. On a 40 hour week: £32,319.60 divided by 2,080 = £15.54 an hour.
| Item | Calculation | Amount |
|---|---|---|
| Gross salary | £40,000.00 | |
| Income tax at 20 percent | £27,430 x 0.20 | £5,486.00 |
| Employee National Insurance at 8 percent | £27,430 x 0.08 | £2,194.40 |
| Total deductions | £5,486.00 + £2,194.40 | £7,680.40 |
| Take-home pay | £40,000 – £7,680.40 | £32,319.60 |

What is forty thousand pounds a year per hour for the hours you actually work?
After 28 days of paid leave on a 37.5 hour contract, you actually work about 1,740 hours a year, so £40,000 is £22.99 an hour gross and £18.57 an hour net for each hour worked. Regular unpaid overtime pulls it the other way: at 45 hours a week it falls to £17.09 gross.
The contracted rate divides by paid hours, including holiday. The worked rate divides by the hours you are actually at your desk. Use the contracted rate to compare job offers, and the worked rate when you price your own time.
| View | Hours a year | Gross per hour | Net per hour | Use it for |
|---|---|---|---|---|
| Contracted, 37.5h week | 1,950 | £20.51 | £16.57 | Comparing salaried job offers |
| Worked, after 28 days leave | 1,740 | £22.99 | £18.57 | Setting a freelance rate to replace the job |
| Regular 45h week with unpaid overtime | 2,340 | £17.09 | £13.81 | Judging whether the job still pays fairly |
No competitor table we checked puts all three views side by side with the net column included. Most show contracted gross only, which flatters the salary in a job comparison and underprices you badly in a freelance comparison.
Watch out: Pension contributions are not in these figures. If you pay 5 percent into a workplace pension, that is £2,000 a year of contributions, and after income tax and National Insurance relief your take-home falls by roughly £1,440, which knocks about 74p an hour off the net rate on a 37.5 hour week. Add your own pension percentage into the calculator rather than using the headline net rate.
How does an employee on forty thousand pounds compare with a sole trader?
An employee on £40,000 takes home £32,319.60 in 2026/27 after Class 1 National Insurance at 8 percent. A sole trader with £40,000 of profit takes home £32,868.20, because Class 4 National Insurance is 6 percent instead. The income tax is identical at £5,486.00, so the National Insurance class alone creates the £548.60 gap.
The gap comes from one line only: £27,430 x 2 percent, the difference between the 8 percent employee rate and the 6 percent self-employed rate on the same slice of income. Our step-by-step guide to how to calculate your self-employed tax shows the Class 4 version of this walk in full.
Do not read that gap as free money. The employee also gets paid holiday, sick pay, and usually an employer pension contribution. The sole trader funds all three from the same £40,000 and files Self Assessment. The sole trader needs to charge well above £16.57 net per hour just to stand still, which is why our guide to freelance hourly rate versus salary warns against treating a salary equivalent as a freelance rate.
If you are weighing up going self-employed on similar money, run both sides properly: the employee side with the UK income tax calculator and the sole trader side with LancerBill’s Self-Employed Tax Calculator UK, then compare the two take-home figures, not the two gross figures.
A worked scenario: a shorter week on forty thousand pounds versus a longer week on a higher salary
Here is the comparison this salary level is famous for. Offer A pays £40,000 for a 37.5 hour week. Offer B pays £42,000 for a 40 hour week. The headline says B wins by £2,000. The hourly maths says something else.
| Offer | Hours a year | Gross per hour | Take-home pay | Net per hour |
|---|---|---|---|---|
| A: £40,000 at 37.5 hours a week | 1,950 | £20.51 | £32,319.60 | £16.57 |
| B: £42,000 at 40 hours a week | 2,080 | £20.19 | £33,759.60 | £16.23 |
Offer B’s tax, for the record: £42,000 minus the £12,570 Personal Allowance is £29,430, taxed at 20 percent gives £5,886.00, and Class 1 National Insurance at 8 percent gives £2,354.40, leaving £33,759.60.
So B pays £1,440 more take-home a year, but asks for 130 more hours to earn it. That values each extra hour at £1,440 divided by 130, which is £11.08 net, well below the net rate of either job. B is still the bigger income. But if your time has other uses, A is the better hourly deal, and a template page that converts one salary at a time will never show you that.
Should you compare offers against the gross or net hourly rate?
Use gross when you compare two salaried jobs on the same terms, because both carry the same tax treatment and contracted hours tell the real story. Use net, and then the holiday adjusted net rate, when you compare a salary with freelance or contract work, because you will fund leave, pension and gaps yourself.
A simple decision framework:
- Salaried job versus salaried job: compare gross hourly on contracted hours. As the scenario above shows, a £42,000 salary on a 40 hour week pays less per hour than £40,000 on a 37.5 hour week, so compare the rate, not just the salary.
- Salaried job versus hourly contract: compare net hourly first, then check what the contract excludes. No paid leave on the contract side means its rate needs to beat £18.57, the holiday adjusted net figure, not £16.57.
- Salary versus going freelance: start from £22.99 gross per worked hour, then add a margin for pension, insurance, admin time and gaps between clients. Pricing at the salary equivalent is the classic route to earning less than you did as an employee.
When you are ready to build a freelance rate from this salary, LancerBill’s freelance rate calculator takes your target income, billable hours and costs and works the rate out properly, rather than copying the employee figure across.
Rule of thumb: never quote one hourly figure for a £40,000 salary without naming its basis. Gross or net, contracted or worked hours: the basis is the answer.
Key takeaways
- £40,000 a year is £20.51 an hour gross and £16.57 an hour after tax on a 37.5 hour week in the UK for 2026/27.
- On a 40 hour week the same salary is £19.23 gross and £15.54 net an hour. The hours basis changes the answer, so always state it.
- Income tax is £5,486.00 and employee Class 1 National Insurance at 8 percent is £2,194.40, leaving take-home pay of £32,319.60.
- Per hour actually worked after 28 days of leave, the rate rises to £22.99 gross and £18.57 net. That is the figure to price freelance work from.
- A £42,000 salary on a 40 hour week pays less per hour than £40,000 on 37.5 hours, and its extra take-home values each extra hour at just £11.08 net.
- A sole trader on £40,000 of profit keeps £548.60 more because Class 4 National Insurance is 6 percent, but funds holiday, sick pay and pension alone.

Stepping up a band, the £50,000 a year per hour breakdown works the same conversion at the higher-rate threshold.
Frequently asked questions
How much is £40,000 a year per hour in the UK after tax?
£16.57 an hour on a 37.5 hour week, or £15.54 an hour on a 40 hour week, for 2026/27 in England, Wales and Northern Ireland. That is take-home pay of £32,319.60, after income tax of £5,486.00 and employee National Insurance of £2,194.40, divided by your paid hours.
How much is £40,000 a year per month and per week?
Gross, it is £3,333.33 a month and £769.23 a week. After income tax and employee National Insurance in 2026/27, take-home is £2,693.30 a month and £621.53 a week, assuming a standard tax code with no pension or student loan deductions.
Why do different calculators give different hourly rates for £40,000?
Because they divide by different hours. A 37.5 hour week gives 1,950 hours a year and £20.51 gross, a 40 hour week gives 2,080 hours and £19.23, and calculators that remove holiday and bank holidays divide by fewer worked hours and produce a higher net rate. Some also use old tax years or quote a net rate with no workings. Always check the hours basis and tax year.
Is £40,000 a year a good salary in the UK?
It depends on your hours, costs and location, and this guide does not rank salaries. What the numbers show is that £40,000 is £20.51 an hour gross on a standard contract, and £22.99 for each hour you actually work after leave. Judge an offer against those rates and against the cost of the hours you give up, not against the headline salary alone.
How much would a freelancer need to charge to match a £40,000 salary?
More than the £22.99 gross per worked hour. A freelancer has no paid leave, no employer pension and unpaid admin and marketing time, so the chargeable rate must cover those on top of the salary equivalent. Use a freelance rate calculator with your real billable hours and costs to set the figure, rather than copying the employee hourly rate.
Do the figures change if I live in Scotland?
Yes, for income tax only. Scotland sets its own income tax bands, so the tax on £40,000 and the net hourly rate differ from the England, Wales and Northern Ireland figures in this guide. Employee National Insurance is UK-wide and stays at 8 percent between £12,570 and £50,270.
