The formula
Examples
| FTE salary | Hours (of 37.5) | Pro rata pay |
|---|---|---|
| £30,000 | 30 | £24,000 |
| £30,000 | 22.5 | £18,000 |
| £42,000 | 15 | £16,800 |
Part of the year
Starting in October? You earn the remaining months’ share: £30,000 × 6/12 = £15,000 for that tax year.
Holiday is pro rata too
Part-time workers get statutory holiday in proportion: 3 days a week = 16.8 days a year. Use the holiday entitlement calculator.
Term-time contracts
School roles may be both part-time and term-time only, so pay is reduced twice – check the number of paid weeks.
