Enter one figure (an hourly rate, a weekly wage, a monthly salary or an annual salary) and the hours you work a week. You get the same pay for every period, with the workings, and a check against the minimum wage for your age from 1 April 2026: £12.71 an hour at 21 and over. The rates are the same in England, Scotland, Wales and Northern Ireland.
Enter the pay and what it covers
Start from the figure you have: an hourly rate from a job advert, a weekly wage, a monthly payslip or an annual salary. Say whether it is gross (before tax and National Insurance) or net: the conversion is the same, but only gross pay is compared with the minimum wage.
Enter your hours
A year is taken as 52 weeks and a month as 52 ÷ 12 weeks, so 37.5 hours a week are 162.50 hours a month and 1,950 hours a year. Every week counts in full, paid holiday included. The days you work a week give the daily figure.
Check the minimum wage
Choose your age band. From 1 April 2026 the National Living Wage is £12.71 an hour at 21 and over; the National Minimum Wage is £10.85 at 18 to 20 and £8.00 under 18; the apprentice rate is £8.00 for apprentices under 19, or 19 and over in the first year of their apprenticeship. The calculator warns you when gross pay for your hours falls short.
Overtime and working time
UK law sets no overtime premium: your contract says how overtime is paid, and your average pay for all the hours you work must not fall below the minimum wage. The calculator notes hours above the 48-hour weekly average, which needs an opt-out unless the job is exempt, and hours above the 40-hour week or 8-hour day allowed under 18.
What is not covered
The accommodation offset, deductions, salary sacrifice and the premium part of overtime or shift pay, which change what counts as pay for the minimum wage: GOV.UK takes the premium out, so leave it out of the amount you enter. Holiday pay entitlement, income tax and National Insurance are not covered either. To go from gross to take-home pay, use a take-home pay calculator.
Rounding and using the result
Each figure is worked out from the amount you enter and rounded once to the nearest penny, with halves rounded up. Copy the workings, export them as a CSV file or save them to Priostack.
Weekly pay = hourly rate × hours a week.
Monthly pay = hourly rate × hours a week × 52 ÷ 12.
Annual pay = hourly rate × hours a week × 52.
Daily pay = weekly pay ÷ days worked a week.
The other way: hourly rate = annual salary ÷ 52 ÷ hours a week, or monthly salary × 12 ÷ 52 ÷ hours a week.
Example: GOV.UK's weekly pay of £346.15
GOV.UK's minimum wage guidance takes a worker paid £346.15 a week for 26.92 hours: £346.15 ÷ 26.92 = £12.86 an hour. Over 52 weeks that is £346.15 × 52 = £17,999.80 a year, or £1,499.98 a month: the example's £18,000 salary, less the 20p lost when it was split into weekly payments. At the National Living Wage of £12.71 and 37.5 hours a week, annual pay is £12.71 × 37.5 × 52 = £24,784.50.
