Part-time pay and leave are normally pro-rated by hours: work 24 hours of a 40-hour week and you get 60% of the full-time salary and leave.

Also called: Pro-rata salary calculator, Part-time salary calculator.

## Inputs
- Your hours per week (unit h; default 24)
- Full-time hours per week (unit h; default 40)
- Full-time days per week (unit days; default 5)
- Full-time annual salary (default 50000; optional)
- Full-time annual leave (unit days; default 25; optional)
- Currency

## Results
- Pro-rata salary
- FTE
- Share of full time
- Pro-rata annual leave
- Equivalent days per week

## Formula

```
FTE = Hours ÷ Full-time hours;  Pro-rata salary = Full-time salary × FTE;  Pro-rata leave = Full-time leave × FTE
```

Where:
- Hours: your contracted weekly hours
- Full-time hours: the full-time week for the same role

## Worked example
1. FTE = 24 ÷ 40 = 0.6.
2. Salary = 50,000 × 0.6 = $30,000.
3. Leave = 25 × 0.6 = 15 days, and 0.6 × 5 = 3 days a week.

**Result:** 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.
