Firefighter overtime calculator
Turn an hourly rate, a block of extra hours and the relevant enhancement into a gross and indicative take-home figure.
How firefighter overtime is calculated
Gross overtime is the hourly rate multiplied by the number of hours and the applicable enhancement. For example, four hours at £18.43 with a 1.5 multiplier produces £110.58 gross.
Frequently asked questions
What overtime rate do UK firefighters receive?
The national 2026 firefighter role table publishes overtime at time-and-a-half for eligible roles. Local agreements and the circumstances of the duty can differ, so the calculator also accepts a custom multiplier.
Is the take-home figure a payslip calculation?
No. It applies a chosen marginal Income Tax rate, employee National Insurance and an optional pension percentage to the overtime payment. PAYE is cumulative, so payroll may differ.
Where can I find my published hourly rate?
Use the July 2026 pay scales or the salary calculator. A competent firefighter is listed at £18.43 an hour and £27.65 for overtime from 1 July 2026.
