UK Holiday Entitlement Calculator

Pick your working pattern at the top. Choose "Fixed days per week" if you work a set number of days, or "Irregular hours" if your hours vary week to week.

For a fixed pattern, set the days worked per week using the plus and minus buttons. A 5-day week earns the full 28-day statutory minimum.

Enter the months worked in the leave year. Use 12 for a full year, or fewer months to pro-rate entitlement for a starter or a leaver who was only employed for part of the year.

For irregular hours, enter the total hours worked in the period. The calculator applies the 12.07% statutory accrual rate to show how much paid holiday you have built up.

UK statutory holiday is set by the Working Time Regulations 1998. Every worker is entitled to 5.6 weeks of paid leave a year. That entitlement is then expressed in days based on how many days you work.

For a fixed working pattern, the formula in words is: days worked per week multiplied by 5.6, then capped at 28 days. So a 5-day week is 5 times 5.6, which is 28 days. A 4-day week is 4 times 5.6, which is 22.4 days. A 3-day week is 3 times 5.6, which is 16.8 days.

The 28-day cap applies to anyone working 5 or more days a week. Working a 6-day or 7-day week does not push the statutory minimum above 28 days, although an employer is free to offer more generous contractual leave.

To pro-rate for part of a year, the full-year figure is multiplied by the fraction of the leave year worked. The calculator uses months worked divided by 12. A 5-day-week starter who worked 6 months gets 28 times 6 over 12, which equals 14 days.

For irregular hours, paid leave accrues at 12.07% of the hours worked. That percentage is 5.6 weeks of holiday divided by the 46.4 working weeks in a year. So 1,000 hours worked accrues 120.7 hours of paid holiday. This method is intended for genuinely irregular-hours and part-year workers.

The headline figure shows your entitlement for the months worked, in days for a fixed pattern or in hours for irregular hours. This is the paid leave you are legally owed for the period you entered.

The full-year entitlement shows what you would get for a complete leave year, and the same amount is also shown in weeks. For a week of 5 days or fewer worked across a full year, this equals the 5.6-week statutory baseline. Once the 28-day cap applies, on a 6-day or 7-day week, the weeks figure falls below 5.6 because the capped days are spread over more working days.

If you work 5 or more days a week, you will see a note that the 28-day cap applies. This is normal and means your statutory minimum is fixed at 28 days regardless of extra working days.

These figures are the statutory minimum only. Your contract may give you more, and your employer decides whether bank holidays are included within the 28 days or granted on top.
