How £18 an hour adds up
To turn an hourly wage into a yearly salary, multiply the rate by hours worked per week, then by weeks worked per year: £18 × 37.5 × 52 = £35,100 before tax. That is the standard full-time assumption; if you take unpaid time off, use fewer weeks (for example 50 weeks gives £33,750).
The £35,100 figure is gross pay. After Income Tax and National Insurance, take-home is about £28,792 a year for England, Wales & NI — £2,399 a month or £554 a week. The exact amount depends on your circumstances, so run it through the calculator below for your own numbers.
