Holiday Calculator UK

Use our free UK holiday calculator to work out holiday entitlement for full-time and part-time employees.

The calculator can help you work out annual leave for employees who work regular days or hours, including people who start part-way through the year, leave part-way through the year, or need their holiday calculated on a pro-rata basis.

Start Calculation

What can this holiday calculator work out?

You can use this calculator to help work out:

• full-time holiday entitlement
• part-time holiday entitlement
• pro-rata holiday entitlement
• holiday entitlement for employees starting part-way through the year
• holiday entitlement for employees leaving part-way through the year
• annual leave entitlement including bank holidays

The calculator is designed for UK employees with a regular working pattern. It gives you a quick estimate of statutory holiday entitlement based on the information you enter.

How UK holiday entitlement is calculated

Most UK workers are legally entitled to 5.6 weeks’ paid holiday each year.

For someone working 5 days per week, this usually works out as:

5 days × 5.6 weeks = 28 days’ holiday per year

For part-time employees, holiday entitlement is usually calculated on a pro-rata basis. For example:

3 days × 5.6 weeks = 16.8 days’ holiday per year

You must not round statutory holiday entitlement down. You can keep the exact figure, such as 16.8 days, or round it up if you prefer.

Holiday entitlement for starters and leavers

If an employee starts or leaves part-way through the holiday year, they are usually entitled to a proportion of their annual holiday allowance.

The calculator can help estimate holiday entitlement based on the employee’s start date, leaving date and your holiday year.

Does this calculator include bank holidays?

Yes. The calculator can be used where holiday entitlement includes bank holidays.

In the UK, the statutory minimum holiday entitlement is 5.6 weeks per year. For a full-time employee working 5 days per week, this is usually 28 days in total. Those 28 days may include bank holidays.

Does this calculator work for zero-hours or irregular-hours workers?

This calculator is designed for employees with a regular working pattern.

Different rules may apply for irregular-hours and part-year workers. For leave years starting on or after 1 April 2024, statutory holiday entitlement for irregular-hours and part-year workers is normally accrued at 12.07% of hours worked in each pay period.

If your employee works irregular hours, you should check the current GOV.UK guidance or use the official GOV.UK holiday entitlement calculator.

Need an easier way to manage staff holidays?

This calculator is useful for working out individual holiday entitlement, but managing holidays in a spreadsheet can quickly become difficult as your team grows.

The Holiday Tracker helps you manage staff holiday requests, approvals, entitlement, sickness and other absences in one simple system.
