Pro Rata Holiday Calculator
Calculate your holiday allowance based on the time you have worked.
This calculator provides an estimate. Your actual holiday entitlement may depend on your employer's rules and local employment laws.
Pro Rata Holiday Calculator
A Pro Rata Holiday Calculator helps you estimate how much holiday leave you may have earned based on the amount of the holiday year you have worked.
It is useful when you start a new job, leave a job during the holiday year, or work part-time. Enter your full holiday allowance and the time you have worked to calculate your estimated pro rata holiday.
What Does Pro Rata Holiday Mean?
Pro rata holiday means getting a fair share of your full holiday allowance based on how much of the holiday year you have worked.
For example, suppose your full annual holiday allowance is 24 days. If you work for half of the holiday year, you may earn half of your annual allowance.
Holiday Earned:
24 × 0.5 = 12 days
So, your estimated pro rata holiday allowance is 12 days.
How to Calculate Pro Rata Holiday
The basic formula is:
You can calculate the holiday based on months, days, or another period used by your employer.
Using Months Worked
If you use months, divide the number of months worked by 12 months.
For example, suppose your annual holiday allowance is 24 days and you work for 6 months.
6 ÷ 12 = 0.5
24 × 0.5 = 12 days
Your estimated pro rata holiday is therefore 12 days.
Using Days Worked
You can also calculate holiday based on the number of days worked during the holiday year.
For example, if your annual allowance is 28 days and you have worked half of the holiday year:
28 × 0.5 = 14 days
For Part-Time Employees
Part-time employees can also receive a pro rata holiday allowance. The calculation depends on the employee's working pattern and the holiday rules used by the employer.
For example, if a full-time employee receives 25 days of annual leave and a part-time employee works 80% of the full-time schedule, a simple proportional calculation would be:
This is a simple example. Your actual holiday entitlement may depend on your employer's policy and local employment rules.

When Is Pro Rata Holiday Used?
Pro rata holiday calculations can be useful in several common situations.
Starting a New Job
If you start a job partway through the holiday year, you may earn only part of the full annual holiday allowance.
Leaving a Job
If you leave your job before the end of the holiday year, your holiday entitlement may be calculated based on the part of the year you worked.
Working Part-Time
Part-time employees may have a holiday allowance based on their working pattern or hours compared with a full-time employee.
Changing Working Hours
If your working hours change during the holiday year, your holiday entitlement may also need to be adjusted.
Pro Rata Holiday Example
Suppose an employee has a full annual holiday allowance of 30 days and works for 4 months of a 12-month holiday year.
First calculate the part of the year worked:
Then calculate the holiday:
So, the estimated pro rata holiday allowance is 10 days.
Full Holiday vs Pro Rata Holiday
Full holiday allowance is the amount of leave available for the complete holiday year. Pro rata holiday is the part of that allowance earned for the period worked.
| Term | Meaning |
|---|---|
| Full Holiday Allowance | Holiday available for the complete holiday year. |
| Pro Rata Holiday | Part of the full allowance earned during the period worked. |
| Months Worked | Number of months worked during the holiday year. |
| Days Worked | Number of days worked during the holiday year. |
| Part-Time Work | Working fewer hours than the full-time schedule. |
