UK Holiday Entitlement Calculator
Work out your statutory paid holiday for a full-time, part-time, hours-based or part-year job. Rules checked against GOV.UK on 11 October 2026.
Estimate of the statutory minimum only, using the rules checked on 11 October 2026. Your contract may give you more. Fractions of a day may be rounded up by your employer but not down. For irregular hours the 12.07% accrual rate is used and the months box is ignored.
| Days per week | Days of paid holiday |
|---|---|
| 1 | 5.6 |
| 2 | 11.2 |
| 3 | 16.8 |
| 4 | 22.4 |
| 5 or more | 28 (maximum) |
Bank holidays can count towards these days if your employer includes them. England has 8 a year; Scotland and Northern Ireland have different numbers.
Frequently asked questions
How much paid holiday am I entitled to in the UK?
Almost all workers are entitled to at least 5.6 weeks of paid holiday a year. For someone working five days a week that is 28 days, which can include bank holidays. The statutory entitlement is capped at 28 days, although your contract can give you more.
How do I calculate holiday entitlement for part-time workers?
Multiply the number of days you work each week by 5.6. For example, 3 days a week gives 16.8 days of leave a year. If you work by the hour, multiply your weekly hours by 5.6 to get your entitlement in hours.
How is holiday worked out for zero-hours or irregular hours?
If you do not work a set pattern, your leave builds up at 12.07% of the hours you work in a pay period. For example, 100 hours worked earns about 12.07 hours of paid holiday. This method is for irregular hours and part-year workers whose hours vary.
Do bank holidays count towards my 28 days?
They can. Your employer may count bank holidays as part of your 5.6 weeks or give them as extra leave. Check your contract. If they are included, a full-time worker in England has 8 of the 28 days used by bank holidays, leaving 20 other days.
How is holiday calculated if I start or leave part-way through the year?
It is worked out pro rata for the part of your employer's leave year that you worked. For example, if you worked 6 months of the leave year, you earn about half the annual entitlement. Your employer's leave year may not match the calendar year.
Can my employer round my holiday entitlement down?
No. If the calculation gives a fraction of a day, your employer may round up, but they cannot give you less than your statutory entitlement. Check your contract for how fractions are handled.
Is this the same as the GOV.UK calculator?
It uses the same published rules. This tool is an estimate for statutory minimum leave. Your contract may give you more, and some situations, such as shift patterns, are more complex. For a legally binding answer, check GOV.UK, Acas or your employer.
How do I work out holiday for a part-time job?
Multiply the number of days you work each week by 5.6. Three days a week gives 16.8 days. If you work set hours, multiply weekly hours by 5.6 to get holiday in hours.
How much holiday do I get if I work irregular hours?
Holiday builds up at 12.07% of the hours you work. For every 100 hours worked you earn about 12.07 hours of holiday.
What happens to my holiday if I start part-way through the year?
Your entitlement is scaled to the months you work in the leave year, so starting with six months to go gives about half the full-year figure.
Does working more than five days a week give me more holiday?
No. The statutory minimum is capped at 28 days, so five days a week and six days a week both give 28 days. Your contract can offer more.
About this tool
Almost all UK workers get at least 5.6 weeks of paid holiday a year, capped at 28 days. Part-time workers get the same amount pro rata, and people with irregular hours build up leave at 12.07% of the hours they work. This tool applies those published rules. Sources: GOV.UK holiday entitlement and Acas. Rules last checked on 11 October 2026. This is general information, not legal advice.
Worked examples
Set days. Someone working three days a week gets 3 × 5.6 = 16.8 days of paid holiday over a full leave year. Someone working two and a half days on average gets 14 days. Five days a week hits the 28-day cap, so working six or seven days a week does not raise the statutory minimum.
Set hours. A 37.5-hour week with a 7.5-hour day gives 37.5 × 5.6 = 210 hours, which is 28 days. A 20-hour week spread over five 4-hour days gives 112 hours, also 28 days, because the weekly pattern still covers five days. A 16-hour week made of two 8-hour days gives 89.6 hours, which is 11.2 days.
| Hours per week | Hours in a working day | Holiday hours | Equivalent days |
|---|---|---|---|
| 37.5 | 7.5 | 210 | 28 |
| 20 | 4 | 112 | 28 |
| 24 | 8 | 134.4 | 16.8 |
| 16 | 8 | 89.6 | 11.2 |
If you only work part of the leave year
If you start or leave partway through the year, the calculator scales the full-year figure by the months worked divided by 12. The table shows what that gives for a five-day and a three-day week.
| Months worked | 5 days a week | 3 days a week |
|---|---|---|
| 3 | 7 | 4.2 |
| 6 | 14 | 8.4 |
| 9 | 21 | 12.6 |
| 12 | 28 | 16.8 |
Irregular and zero-hours work
If your hours change each period, holiday builds up at 12.07% of the hours you work, which is 5.6 weeks of holiday as a share of the working year. Working 1,000 hours in a leave year earns 120.7 hours of holiday, and a month with 160 hours worked earns about 19.3 hours. The calculator treats that figure as hours, so divide by your usual shift length to see roughly how many shifts it covers.
Checking your contract
The figures here are the statutory minimum. Many contracts give more, and some include or exclude bank holidays from the total, so check whether the 28 days is on top of bank holidays or includes them. Your employer may round part days up but not down. If you are unsure, your payslip, contract or staff handbook sets what you actually get, and ACAS and GOV.UK explain the rules in full.
