The formula
Annual salary = hourly rate × hours a week × 52
Hourly rate = annual salary ÷ 52 ÷ hours a week
Example: £15 an hour, 37.5 hours a week → 15 × 37.5 × 52 = £29,250 a year, £2,437.50 a month.

FAQ
How do I convert an hourly wage to an annual salary?
Multiply your hourly rate by your paid hours a week, then by 52. £15 an hour at 37.5 hours a week is 15 × 37.5 × 52 = £29,250 a year. At 40 hours a week that is 2,080 paid hours a year, so a quick estimate is hourly rate × 2,000.
How do I work out my hourly rate from my salary?
Divide the annual salary by 52 and then by your weekly hours. £30,000 at 37.5 hours a week is 30,000 ÷ 52 ÷ 37.5 = £15.38 an hour. For a monthly salary, multiply by 12 first.
Why multiply by 52 and not 48 when I get holidays?
Salaried employees are paid during their holidays, so a salary covers all 52 weeks. If you are only paid for the weeks you work (for example as a contractor or on a zero-hours contract), open "Days a week and unpaid weeks" and enter the weeks you actually get paid, e.g. 46–48.
Is a month 4 weeks?
No, a month is on average 52 ÷ 12 = 4.33 weeks. That is why weekly pay × 4 is less than the monthly salary. The calculator converts via the year, so monthly pay = annual pay ÷ 12.
What is $20 an hour at 40 hours a week per year?
$20 × 40 × 52 = $41,600 a year, $3,466.67 a month, $1,600 every two weeks and $800 a week, before tax.
Are the results before or after tax?
Before tax (gross). Income tax, National Insurance or Social Security, and pension contributions come off afterwards and depend on where you live and your tax code.
