The same £45 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.

What the workplace pension changes at £45 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.

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 £45 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 £87,750 a year:

5 plans apply at this rate; a borrower is only on one of them, so use the line that matches your loan.

£45 an hour in England versus Scotland

What 7.5 extra hours a week are worth at £45

A 45-hour week at the same rate adds £17,550 of gross pay a year (£1,463 a month) and £9,119 of take-home (£760 a month). The gap between those two numbers is the marginal rate on the extra hours: 48.0% 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 £4,559 more in the hand.

Is £45 an hour a good wage in the UK?

It is £87,750 a year before tax and £5,121 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 30.0%, 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.
