The amount of annual leave accrued per week depends on the total annual entitlement and the number of weeks worked per year.
- For a full-time employee entitled to 4 weeks of annual leave per year, the accrual rate is approximately 0.0767 weeks of leave per week worked, which translates to about 3 hours of leave for a standard 40-hour workweek.
- In hours, this is typically calculated as 4 weeks × 38 hours per week = 152 hours of annual leave per year, which accrues at about 2.923 hours of leave per week worked.
- Part-time employees accrue leave on a pro-rata basis based on their hours worked compared to a full-time 38-hour week. For example, working 20 hours per week results in about 1.538 hours of leave accrued per week.
- In percentage terms, some systems use a 12.07% accrual of hours worked per pay period, which means you accrue roughly 0.12 hours of leave for every hour worked.
So, the general formula for weekly accrual of annual leave is:
Annual leave accrued per week=Annual leave entitlement in hoursNumber of weeks in the year (52)\text{Annual leave accrued per week}=\frac{\text{Annual leave entitlement in hours}}{\text{Number of weeks in the year (52)}}Annual leave accrued per week=Number of weeks in the year (52)Annual leave entitlement in hours
For a full-time employee working 38 hours a week with 4 weeks leave entitlement:
152 hours52 weeks≈2.923 hours per week\frac{152\text{ hours}}{52\text{ weeks}}\approx 2.923\text{ hours per week}52 weeks152 hours≈2.923 hours per week
This means an employee accrues about 2.9 hours of annual leave for every week worked at full-time hours.
