A pro rata salary is a full-time salary scaled proportionally to reflect the hours or days actually worked. If a role is advertised at £35,000 FTE (full-time equivalent) and you work 3 days out of a standard 5-day week, your pro rata salary is £35,000 × (3 ÷ 5) = £21,000.
Pro Rata Salary = FTE Salary × (Your hours or days ÷ Full-time hours or days)
For part-year workers (such as term-time staff), multiply by a second fraction:
Pro Rata Salary = FTE Salary × (Your hours ÷ FTE hours) × (Your weeks ÷ 52)
Use hours when your contract specifies a number of hours per week (e.g. 22.5 hours out of 37.5). Use days when you work whole days and your contract specifies days per week (e.g. 3 days out of 5). Both methods give the same result if your daily hours are consistent.
Workers on term-time or seasonal contracts work fewer than 52 weeks per year. Their pro rata salary reflects both the reduced weekly hours and the shorter working year. For example, a teaching assistant working 37.5 hours a week for 39 weeks on a £28,000 FTE salary would receive:
£28,000 × (39 ÷ 52) = £21,000 pro rata
Part-time workers are entitled to the same proportion of statutory annual leave as full-time colleagues. The statutory minimum is 5.6 weeks per year (28 days for a 5-day week). A part-time worker doing 3 days a week is entitled to 5.6 × 3 = 16.8 days. Use our Holiday Entitlement Calculator to calculate your exact figure.
