Method
FTE = Hours ÷ Full-time hours; Pro-rata salary = Full-time salary × FTE; Pro-rata leave = Full-time leave × FTE
- Hours
- your contracted weekly hours
- Full-time hours
- the full-time week for the same role
Worked example
- FTE = 24 ÷ 40 = 0.6.
- Salary = 50,000 × 0.6 = $30,000.
- Leave = 25 × 0.6 = 15 days, and 0.6 × 5 = 3 days a week.
Working 24 of 40 hours is 0.6 FTE: $30,000 a year and 15 days of leave on a $50,000, 25-day full-time package.
What the result means
If your days are of different lengths, leave measured in hours is fairer than leave in days: 0.6 × 25 days × 8 hours = 120 hours.
Assumptions and limits
- Pay and leave are pro-rated strictly by contracted hours.
- Benefits that are not pro-rated (for example some health plans) and local minimum-leave rules are not modelled.
Questions
Should part-time leave be pro-rated by days or hours?
By whichever matches how you work. If you work three full days, 3 ÷ 5 and 24 ÷ 40 give the same answer; if your days are shorter, use hours.
Are public holidays pro-rated too?
Often yes, so part-timers are not advantaged or disadvantaged by which weekdays they work. Check your policy.
