How to use the Holiday Calculator
A holiday calculator is a useful tool for figuring out how much annual leave an employee should get. In the UK, full-time staff are entitled to 28 days (or 5.6 weeks) of paid holiday each year, while part-time employees receive a proportional amount depending on the hours or days they work. The calculator makes it easy to work out the correct entitlement, which is especially helpful for employees who start or leave during the year.
This tool also helps make sure holiday allowances are calculated fairly and follow UK law.
A holiday calculator helps employers save time and avoid errors, while giving employees a clear idea of their leave. In other words, it makes tracking annual leave straightforward, accurate, and far less stressful.
What is pro-rata holiday entitlement?
An employee’s pro-rata holiday entitlement is calculated by dividing their total annual leave allowance by the part of the holiday year they have already completed.
Full-time employees who work five days a week are entitled to a minimum of 28 days of paid annual leave, or 5.6 weeks of vacation.
Part-time employees receive 5.6 weeks of vacation time. This is in addition to working the same number of hours Monday through Friday. In practice, however, this usually means they get fewer than 28 days since they work fewer hours overall.
Zero-hours workers also get 5.6 weeks of annual leave, but it is often simpler to calculate their holiday in hours instead of days. Their hours can change from week to week—for example, 12 hours one week, 20 the next, and none the following.
Employers should average the hours worked over the last 52 weeks to calculate this fairly. They should replace earlier paid weeks for any weeks where no hours were worked and no payment was received.

What is the legal minimum for holiday entitlement in the UK?
Everyone working in the UK has a basic right to holiday entitlement. This ensures they receive a minimum amount of paid leave each year. Full-time employees, who usually work a five-day week, get up to 28 days off, which is about 5.6 weeks of holiday.
For part-time workers, their holiday entitlement is adjusted based on their hours. This way, all employees receive a fair amount of downtime.
For instance, someone who works three days a week would have their holiday calculated by multiplying their working days by 5.6, resulting in 16.8 days of holiday. This method ensures that all employees, regardless of their work pattern, can enjoy their fair share of paid leave.
It’s important to understand and manage your team’s holiday entitlements to follow UK employment laws and demonstrate that your team is treated fairly. By ensuring these allowances are calculated accurately, you can avoid potential disputes and create a workplace that employees appreciate.
How do you calculate pro-rata holiday entitlement?
The easiest way to calculate holiday entitlement is to multiply the number of days an employee works each week by 5.6. For example:
- A full-time employee working 5 days a week would receive 5 × 5.6 = 28 days.
- A part-time employee working 3 days a week would receive 3 × 5.6 = 16.8 days.
It’s important to consider the employee’s weekly work pattern to ensure holiday allowances are accurate and fair.
For employees with different hours on various days, our pro-rata holiday calculator can determine entitlement in both days and hours.
If a staff member starts or leaves part-way through the holiday year, we calculate their entitlement based on the time they have actually worked. This gives their pro-rata holiday entitlement, which is a share of the full annual allowance.
What are the different scenarios for calculating pro-rata holiday entitlement?
For employees who join or leave during the holiday year, whether they are full-time or part-time, their annual leave is calculated based on the time they actually work for your business.
Staff usually earn holiday at a rate of 1/12 of their annual entitlement for each month worked.
How do you calculate holiday entitlement for employees who join or leave partway through the year?
1. Employees Starting Partway Through the Year
When an employee joins partway through the holiday year, we calculate their entitlement from their start date.
To ensure accuracy, consider their start date and the remaining months in the holiday year. For example:
If the holiday year runs from January 1 to December 31 and the employee starts on March 1, their entitlement will cover March through December. Employees earn leave at a rate of 1/12 of the annual entitlement for each month worked. In this case, they would receive 10/12 of a full year’s holiday allowance.
2. Employees Leaving Partway Through the Year
For employees leaving before the end of the holiday year, we calculate entitlement from the start of the holiday year to their leaving date.
Accurate calculation ensures they receive the right amount of leave or pay in lieu:
If an employee has taken more leave than they are entitled to, you can deduct the excess from their final paycheck, provided this was agreed upon in writing. If they have taken less leave than their entitlement, you can pay them for the unused leave.
What other factors should be considered when calculating pro-rata holiday entitlement?
For part-time employees or those who work varying hours each month, holiday calculations are done differently to ensure fairness. It’s also important to consider bank holidays when figuring out their entitlement.
How to Calculate Bank Holiday Entitlement for Employees
For employees with irregular hours, like shift workers or those with changing schedules, holiday pay is based on the average hours they worked over the last 12 weeks.
How Is Holiday Entitlement Accrued?
Employees start earning holiday from their first day on the job.
How Much Holiday Do Employees Earn Each Month?
Holiday is earned monthly as part of the annual entitlement. Staff receive 1/12 of their annual leave each month.
Example:
A full-time employee with 28 days of annual leave starting in January will have earned 14 days by June (6/12 of their annual entitlement). Employees continue to earn leave even if they are on maternity, paternity, adoption, or sick leave.
Part-Time Employees
Accrual is based on the number of days they work each week. For instance, a part-time employee working 2 days per week would have an annual entitlement of: 5.6 weeks × 2 days = 11.2 days. Rounded up, this equals 11.5 days per year. Using monthly accrual, they would earn about 5.75 days by June if they started in January.
Zero-Hours Employees
Accrual is calculated on a pro-rata basis using hours worked instead of fixed days. This ensures their entitlement is fair based on their working pattern.
How to Carry Over Annual Leave?
Carry over means moving unused annual leave into the next holiday year. For example, if an employee still has five days of leave remaining, they may want to carry it over rather than lose it. A holiday calculator can help employees and employers track remaining leave and understand how much holiday is still available.
Under the EU Working Time Directive, employees are entitled to four weeks of paid leave each year. This leave normally needs to be taken within the same holiday year. Using a holiday calculator makes it easier to monitor how much statutory leave has been used and what remains.
In the UK, employees may also be able to carry over up to 1.6 weeks (eight days) of additional leave, but this usually requires employer approval. Employers often track this using a holiday calculator or HR system.
There are exceptions to the rules. If an employee cannot take their leave due to sickness, maternity leave, or similar circumstances, they may carry unused leave into the following year, usually within 18 months.
Ultimately, carry-over rules depend on the employer’s policy, but a holiday calculator can help ensure leave is tracked and managed correctly.
How to Book Time Off?
When an employee wants to take time off, they should usually give notice that is at least twice the length of the leave they plan to take. For example, if an employee wishes to take one week of annual leave, they should normally provide two weeks’ notice.
As an employer, it is important to have a clear process for requesting annual leave. This could be a paper form, an email request, or an online holiday management system. Whatever method you choose, make sure all employees understand how the process works.
Employers can refuse a holiday request if necessary. However, it is good practice to handle this fairly by:
Giving notice that is at least the same length as the leave requested
Explaining the reason for the refusal so the employee understands the decision
Using an HR system can make this process much easier. With Blaze HR, employees can request leave through the mobile app or web portal. Managers can view upcoming holidays in the team calendar, helping them avoid scheduling conflicts and manage staffing more effectively.
