How to calculate part time holiday entitlements

One of the most common questions we are asked is how to calculate a part-time employee’s holiday entitlement.

Perhaps the best way to explain is to give you a number of scenarios. These are all based on a full-time employee working 40 hours per week over five days, Monday to Friday. This full-time employee is entitled to 20 days’ holiday plus 8 bank/public holidays.

Scenario 1.

The employee works five days per week, Monday to Friday, from 9.00am to 1.00pm.

This employee will be entitled to 20 days’ holiday plus 8 bank/public holidays in exactly the same way as a full-time employee, albeit each day will be shorter.

Scenario 2.

The employee works three days per week from 9.00 am to 6.00pm with one hour for lunch.

This employee will be entitled to 3/5 of the entitlement of a full-time employee, including three-fifths of the bank/public holiday entitlement. You might well insist that they take any bank/public holidays that fall on days that they normally work and any remaining entitlement can be taken at a time of their choice.

The calculation in this instance would therefore be:

20 days’ holiday plus 8 bank/public holidays = 28 days in total.

28/5 X 3 = 16.8 days. You are always required to round up to the nearest half day, so this employee would be entitled to 17 days’ holiday inclusive of bank holidays.

Scenario 3.

The employee works four hours on Monday, seven hours on Tuesday, two hours on Wednesday and four hours on Thursday.

In this situation, you would need to calculate the employee’s holiday entitlement in hours.

A full-time employee is entitled to a total of 224 hours’ holiday each year inclusive of bank holidays (28 days x 8 hours). This employee works a total of 17 hours per week compared to a full-time employee who works 40 hours per week. These working hours equate to 42.5% of a full-time worker’s hours.

42.5% of 224 hours is therefore 95.2 hours which would be rounded up to 96 hours.

Again, they would be required to book the number of hours required for any bank holidays that fall on days they would normally work from this entitlement.

Scenario 4.

The employee works six days per week.

This employee would be entitled to the same holiday entitlement as a full-time employee working five days per week – 20 days plus 8 bank/public holidays. Holiday entitlement does not have to be increased because an employee work an extra day each week.
