Holiday Entitlement & Accrual Calculator UK 2026
Work out your statutory holiday entitlement, whether you work regular hours, part-time, or irregular/casual hours.
Under the Working Time Regulations 1998, almost all workers are entitled to a statutory minimum of 5.6 weeks' paid holiday per year. For someone working a standard 5-day week, this works out at 28 days — and 28 days is also the maximum statutory entitlement, even if you work more than 5 days a week.
If you work irregular hours or only part of the year (for example casual, zero-hours, or seasonal work), your holiday is instead calculated as 12.07% of the hours you actually work, under the rules that took effect for holiday years starting on or after 1 April 2024.

Frequently asked questions
How much statutory holiday am I entitled to?
Almost all workers are entitled to at least 5.6 weeks' paid holiday per year. For a standard 5-day week, this is 28 days. The statutory maximum is capped at 28 days even if you work more than 5 days a week.
Does my holiday entitlement include bank holidays?
There is no automatic legal right to time off on bank holidays on top of your statutory entitlement — the 5.6 weeks (28 days for a 5-day week) can include bank holidays. Many employers do provide bank holidays in addition to the statutory minimum, but this is a contractual choice, not a legal requirement.
How is holiday calculated for irregular hours or zero-hours workers?
For holiday years starting on or after 1 April 2024, irregular hours and part-year workers accrue holiday at 12.07% of the hours they actually work in each pay period, rather than a fixed number of days.
What is rolled-up holiday pay?
Rolled-up holiday pay means an employer adds a 12.07% uplift to each payslip instead of paying separately when leave is taken. This was made lawful again for irregular hours and part-year workers from April 2024, and must be clearly itemised on the payslip.
What happens to my holiday if I start or leave partway through the year?
Your entitlement is pro-rated based on the proportion of the holiday year you actually work. Many employers round this up in the employee's favour, but check your contract for the exact method used.
Can I carry over unused holiday to the next year?
This depends on your employer's policy — there is no automatic statutory right to carry over untaken holiday in most cases, except in specific circumstances such as long-term sickness or certain family leave. Check your contract or staff handbook for your employer's carry-over rules.
