Calculating annual leave
Annual leave accrues based on an employeeβs ordinary hours of work. Weβll run through some formulas to help you work out leave entitlements, but you can also use the Fair Work Leave Calculator for precise numbers.
Formula for full-time employees
So, how is annual leave calculated?Β
For full-timers, the maths is pretty straightforward:
Formula: 4 weeks Γ ordinary weekly hours = total annual leave hours per year.
So, if an employee works a standard 38-hour week, they would accrue 152 hours of annual leave per year: 4 weeks Γ 38 hours per week = 152 hours of annual leave.
Formula for part-time employees:
For part-time employees, holiday leave accrual is proportionate to their working hours. Hereβs how to work out annual leave for part-timers:
Formula: (part-time hours per week Γ· 38) Γ 152 hours = total annual leave hours per year.
For example, a part-time employee working 20 hours per week earns 80 hours of annual leave per year: (20 hours Γ· 38) Γ 152 hours = 80 hours of annual leave per year
Formula for irregular hours
If your employees have irregular hours, it can be tricky to calculate how much annual leave per year is accrued. Here's what to do:
- Work out the average weekly hours over a decent amount of time (usually 12 months)
- Use the part-time formula with this average as the βhours per weekβ
Remember, this only applies for part-time employees β casuals donβt accrue annual leave.
