Pro Rata Salary FAQ
Answers to the most frequently asked questions about calculating and understanding pro rata pay.
Pro rata means ‘in proportion’. A pro rata salary takes a full-time equivalent (FTE) salary and scales it down in proportion to the hours or days you actually work, so a role advertised at £30,000 full-time pays £15,000 pro rata for someone working half the hours.
Divide your actual hours per week by the full-time hours per week, then multiply that fraction by the full-time salary. For example, working 22.5 hours against a 37.5-hour full-time week is 0.6 of full-time, so a £30,000 full-time salary becomes £18,000 pro rata.
Yes. In the UK, statutory holiday entitlement is also calculated pro rata for part-time workers, based on the proportion of a full-time working week that they work, rather than simply being capped at a fixed number of days.
Not quite. Pro rata pay is the scaled-down annual, monthly, or weekly salary figure, while hourly pay is the rate per hour. The hourly rate itself usually stays the same as the full-time equivalent; it’s the total pay that is scaled down to reflect fewer hours worked.
