Convert hourly pay to salary, or work out an hourly rate from annual or monthly salary. Use your paid hours and weeks to compare like for like.
How to calculate annual salary from hourly pay
Gross annual salary is your hourly wage multiplied by paid hours each week and paid weeks each year. A £15 hourly wage at 37.5 hours for 52 paid weeks equals £29,250 a year before deductions.
Salary to hourly rate: annual and monthly pay
For an annual salary, divide gross yearly pay by paid hours per week × paid weeks per year. For monthly salary, multiply by 12 first. Choose the conversion at the top of the calculator; all hourly equivalents are before tax.
A £40,000 annual salary at 37.5 hours and 52 paid weeks is about £20.51 an hour. A £2,500 monthly salary is £30,000 a year, or about £15.38 an hour on the same hours. More weekly hours mean a lower hourly equivalent for the same salary.
Hourly pay, paid holiday and unpaid weeks
Use 52 weeks when your contract includes paid holiday and you receive pay throughout the year. If work is seasonal or includes unpaid weeks, enter only the weeks you expect to be paid.
Enter paid hours only: an unpaid lunch break is not paid working time. Gross pay per paid week uses the weeks you enter, while monthly pay and weekly take-home are averages across the whole year.
Estimating take-home pay
The gross conversion works independently of tax. Take-home estimates use England, 1257L, employee NI category A and regular monthly pay, with no pension or student loan. Unpaid periods and irregular shifts can change NI deductions because payroll applies thresholds each pay period. Use the full salary calculator for your region, tax code and deductions.
See our calculation methodology and HMRC’s 2026/27 rates and payroll thresholds. Amounts are rounded to pennies; actual payslips may differ.
Frequently asked questions
How do I convert an hourly wage into an annual salary?
Multiply the hourly rate by paid hours per week and paid weeks per year. For example, £15 an hour × 37.5 hours × 52 weeks gives a gross annual salary of £29,250.
Should I use 52 weeks in an hourly wage calculator?
Use 52 weeks if your holiday is paid and you receive pay throughout the year. Reduce the paid-weeks figure if you expect unpaid weeks or seasonal gaps.
What hourly rate is a £40,000 salary?
At 37.5 paid hours a week for 52 weeks, £40,000 is approximately £20.51 an hour before tax. Different weekly hours produce a different hourly equivalent.
Does the calculator show hourly pay after tax?
The hourly rate is before tax. Take-home results are monthly and weekly annual averages after Income Tax and employee National Insurance, assuming England, 1257L and regular monthly payroll with no pension or student loan.
How do I calculate an hourly rate from a monthly salary?
Multiply gross monthly salary by 12, then divide by paid hours per week times paid weeks per year. For example, £2,500 a month at 37.5 hours and 52 paid weeks is approximately £15.38 an hour before tax.
