How do I account for unpaid weeks?

Enter the number of paid working weeks in the year. For example, a term-time or seasonal worker may use fewer than 52 weeks.

How is overtime calculated?

Regular overtime hours are multiplied by your normal hourly rate and the overtime multiplier, then annualised using the same working weeks.

Why is this only an estimate?

NI and student-loan deductions operate by pay period, so irregular hours and overtime can make the real payroll result differ from an annualised estimate.

Hourly Pay Calculator

Hourly work can be difficult to compare when weekly hours, overtime or working weeks vary. This calculator converts your working pattern into an annual estimate and then applies the same UK payroll assumptions as the take-home pay calculator.

How this calculator works

Your hourly rate is multiplied by standard hours and working weeks. Optional overtime is added using the overtime multiplier you enter. The resulting annual gross estimate is passed through the UK take-home pay engine.

How to use it

Enter your normal hourly rate, weekly hours and weeks worked each year.
Add regular overtime hours and the overtime multiplier if relevant.
Select region, pension method and student-loan plan.
Compare gross hourly earnings with estimated take-home pay.

Assumptions and limitations

Assumes the working pattern entered is representative across the year. Overtime and irregular payroll can change real NI and student-loan deductions because those deductions operate by pay period.
