£15 an hour is how much a year in the UK?
- Income tax£3,33611.4%
- National Insurance£1,3344.6%
- Take-home pay£24,58084.0%
At the UK full-time pattern of 37.5 hours and 52 weeks, £15 an hour is £29,250 a year. Income tax and National Insurance take £4,670, leaving £24,580 — £2,048 a month. Pay the statutory 5% workplace pension and the net becomes £23,659, £920 less, because the pension comes out before income tax.
The same £15 an hour at different weekly hours
Part-time hourly work is not a scaled-down version of full-time work. Each row below is recalculated on its own annual figure, so the tax bill is lower than a straight percentage — at 16 hours a week the personal allowance of £12,570 may wipe income tax out entirely.
| Weekly hours | Hours a year | Annual gross | Income tax | National Insurance | Take-home | Monthly |
|---|---|---|---|---|---|---|
| 16 hours | 832 | £12,480 | −£0 | −£0 | £12,480 | £1,040 |
| 20 hours | 1,040 | £15,600 | −£606 | −£242 | £14,752 | £1,229 |
| 25 hours | 1,300 | £19,500 | −£1,386 | −£554 | £17,560 | £1,463 |
| 30 hours | 1,560 | £23,400 | −£2,166 | −£866 | £20,368 | £1,697 |
| 35 hours | 1,820 | £27,300 | −£2,946 | −£1,178 | £23,176 | £1,931 |

What the workplace pension changes at £15 an hour
Pension contributions work under a net pay arrangement, so they reduce taxable pay but leave National Insurance untouched. At this rate the pension only applies to earnings between £6,240 and £50,270, which is why 8% does not cost 8% of the whole salary.
| Employee contribution | Pension paid | Income tax | National Insurance | Annual take-home | Monthly |
|---|---|---|---|---|---|
| None | — | −£3,336 | −£1,334 | £24,580 | £2,048 |
| 5% | −£1,151 | −£3,106 | −£1,334 | £23,659 | £1,972 |
| 8% | −£1,841 | −£2,968 | −£1,334 | £23,107 | £1,926 |
The employer adds at least 3% on top of your own contribution — money that never appears in these take-home figures because it goes straight into the pension pot.
Student loan at £15 an hour
Repayment is 9% of everything above your plan's threshold (6% for the postgraduate loan), taken from pay rather than from the annual total in one go. At £29,250 a year:
| Plan | Threshold | Rate | Repayment a year | Per month |
|---|---|---|---|---|
| Plan 1 | £26,900 | 9% | −£212 | −£18 |
| Plan 2 | £29,385 | 9% | Nothing | — |
| Plan 4 | £33,795 | 9% | Nothing | — |
| Plan 5 | £25,000 | 9% | −£383 | −£32 |
| Postgraduate loan | £21,000 | 6% | −£495 | −£41 |
3 plans apply at this rate; a borrower is only on one of them, so use the line that matches your loan.
£15 an hour in England versus Scotland
National Insurance and the personal allowance are identical across the UK; only the income tax bands differ. At £29,250 the gap is £40 a year, and it grows quickly above £43,663 where Scotland's higher rate starts.
| Where you work | Income tax | National Insurance | Annual take-home | Difference |
|---|---|---|---|---|
| England, Wales & Northern Ireland | −£3,336 | −£1,334 | £24,580 | — |
| Scotland | −£3,296 | −£1,334 | £24,619 | -£40 |
What 7.5 extra hours a week are worth at £15
A 45-hour week at the same rate adds £5,850 of gross pay a year (£488 a month) and £4,212 of take-home (£351 a month). The gap between those two numbers is the marginal rate on the extra hours: 28.0% goes to tax and National Insurance. Note that this is the same rate as normal pay — UK overtime is not taxed at a special rate, it simply adds to the annual total.
If your contract pays overtime at 1.5× after 37.5 hours, the extra hours are worth half again as much gross, and roughly £2,106 more in the hand.
Nearby hourly rates
Is £15 an hour a good wage in the UK?
It is £29,250 a year before tax and £2,048 a month after tax and National Insurance without a pension. Whether that is comfortable depends on housing, region and household size, which this page cannot know — but the effective deduction rate here is 16.0%, so the gross-to-net gap is the part you can plan around.
How many hours is that a month?
37.5 hours a week averages 163 hours a month — a little over 162. Monthly pay is annual pay divided by 12, not four weeks of pay, which is why a month never equals 4 × a weekly figure.
Why does the tax line jump between neighbouring rates?
Because income tax is banded, not flat. Crossing £100,000 starts the personal allowance taper and creates an effective 60% band until £125,140; National Insurance drops from 8% to 2% at £50,270. Hourly rates either side of those points behave differently even when the pay difference is small.
