Payroll-gradeQuestions
Common questions
How do you calculate a pro-rata salary?
Divide your hours by the full-time hours and multiply by the full-time salary. 22.5 hours of a 37.5-hour week is 60%, so £40,000 becomes £24,000.
How does term-time pay work?
Term-time-only pay scales the full-time salary by the weeks you are paid for, which is the weeks you work plus your statutory holiday, out of the full year. Most employers then spread that annual figure evenly across twelve months, so you are paid the same amount in the holidays as in term time.
