Annual Leave Calculator
Work out your UK holiday entitlement. Enter the days you work each week and the calculator applies the statutory 5.6 weeks (capped at 28 days), pro-rated for part-time and part-year, in days and hours. Irregular or zero-hours? Switch to the 12.07% accrual method.
16.8 days = 126 hours
Statutory entitlement for 3 day(s)/week.
Based on the statutory 5.6 weeks (28-day cap for 5+ day weeks). Whether bank holidays count towards this depends on your contract. Educational estimate, not legal advice. How we calculate →
How holiday entitlement is calculated in the UK
Almost all UK workers are entitled to 5.6 weeks of paid holiday a year. To turn that into days, multiply the days you work each week by 5.6 — so a 5-day week gives 5 × 5.6 = 28 days. For someone working 5 or more days a week, the statutory entitlement is capped at 28 days. The calculator shows your entitlement in both days and hours, and flags when the 28-day cap applies.
Pro-rata holiday for part-time and part-year workers
Part-time staff get the same 5.6 weeks in proportion: 3 days a week × 5.6 = 16.8 days. If you start or leave partway through the holiday year, entitlement is pro-rated to the time worked — roughly one-twelfth of the annual allowance accrues each month. Lower the “weeks worked this year” field to pro-rate a part-year. Where rounding is needed in the first year, part days are rounded up to the nearest half day.
Irregular-hours and zero-hours workers: the 12.07% method
If your hours vary, there's no fixed days-per-week to multiply, so holiday accrues at 12.07% of the hours you actually work. That figure is 5.6 weeks of holiday out of the 46.4 weeks a year you could work (5.6 ÷ 46.4 = 12.07%). For example, 30 hours worked × 12.07% = 3.62 hours of paid leave accrued. Switch the working-pattern selector to “Irregular / zero hours” to use this method.
Do bank holidays count? Statutory vs enhanced
There are 8 bank holidays in England and Wales, but there's no automatic legal right to take them off or to extra pay for working them. Bank holidays can be included within your 5.6 weeks or given on top — it depends on your contract. If your employer offers more than the statutory minimum (say 25 days plus bank holidays), enter the higher figure as your weeks of entitlement; above the statutory minimum there's no 28-day cap.
Frequently asked questions
How much annual leave am I entitled to in the UK?
Almost all workers get 5.6 weeks of statutory paid holiday a year. For someone working 5 or more days a week this equals 28 days, which is the statutory cap regardless of how many days a week you work.
How do I calculate pro-rata holiday for a part-time worker?
Multiply the days worked per week by 5.6 — so 3 days a week gives 3 × 5.6 = 16.8 days. Round up to the nearest half day where required. It's still capped at 28 days for people working 5 or more days a week.
How is holiday calculated for irregular-hours or zero-hours workers?
Use the 12.07% accrual method: holiday builds up at 12.07% of the hours you work (that's 5.6 weeks out of a 46.4-week working year). For example, 30 hours worked earns 30 × 12.07% = 3.62 hours of paid leave.
Do bank holidays count towards statutory annual leave?
They can be included within your 5.6 weeks or given on top — it depends on your contract. There's no automatic right to take bank holidays off, so check whether your 28 days already includes them.
How do I work out holiday for someone starting or leaving partway through the year?
Holiday accrues from day one, roughly one-twelfth of the annual allowance each month, then is pro-rated to the time worked. Six of twelve months on a 28-day allowance is about 14 days. Lower the weeks-worked field to estimate it.
Can unused holiday be carried over to the next year?
Up to 1.6 weeks (the part above the 4-week core) can be carried over if your employer agrees, and core statutory leave can be carried in defined cases such as sickness or family leave. Check your contract for your employer's carry-over policy.
