How to calculate annual leave for part time workers.

Calculating holiday allowances for part time employees can be a struggle, especially if you don’t do it very often. That’s why we built this annual leave calculator, just pop in the data and the calculator will tell you the correct annual leave to provide your staff member.

If you want these calculations to be performed for you automatically, why not take our HR software Staff Squared for a spin? There’s a 14-Day free trial and you can request a demo – we’d love to show you around.

We’ve built this calculator to fit most circumstances but please take care to ensure it fits with the way you work. Our holiday entitlement calculators on the Staff Squared HR software are much more sophisticated, taking into account many more variables. If in any doubt seek advice from a qualified HR consultant.

What is the basic holiday entitlement?

Almost all workers in the UK are legally entitled to 5.6 weeks’ paid holiday each year. This is known as statutory leave entitlement and can include bank holidays.

Employees working a 5-day week get a minimum of 28 days’ paid holiday days each year (including bank holidays).

  • 5 days x 5.6 weeks = 28 days

Part-time workers get less paid holiday as their entitlement is worked out on a pro-rata basis according to the number of hours or days they work. For an employee who normally worked 2 days a week, their holiday entitlement would be 11.2 days.

  • 2 days x 5.6 weeks = 11.2 days

No matter what the working pattern, a worker should still receive holiday pay based on a week’s normal remuneration. For workers with no normal working hours, this is based on the average pay received over the previous 12 weeks.
