100 hours worked × 12.07% = 12.07 hours holiday

Audit note

Rolled-up holiday pay for irregular-hours and part-year workers is lawful again from April 2024, but the 12.07% uplift must be itemised separately on the payslip — not absorbed into the basic rate.

Frequently asked questions

How is zero-hours holiday calculated?
The standard method accrues holiday at 12.07% of the hours you work. Work 100 hours and you earn 12.07 hours of paid leave. The percentage comes from 5.6 weeks as a share of the 46.4 working weeks in a year.
Where does 12.07% come from?
A year has 52 weeks; 5.6 are holiday, leaving 46.4 working weeks. 5.6 ÷ 46.4 = 12.07%, so 12.07% of hours worked reproduces the 5.6-week entitlement for irregular hours.
Can my holiday be rolled up into my pay?
For irregular-hours and part-year workers, rolled-up holiday pay became lawful again from April 2024. It must be an itemised 12.07% uplift on your payslip, not hidden in your basic rate.
