The full-time week changes the hourly rate and every pro rata figure. Check the job advert or contract. The same £57,000 at three common full-time weeks:
How this is worked out
pro rata salary = £57,000 × your hours ÷ full-time hours
Example: £57,000 × 25 ÷ 37.5 = £38,000.00 a year. Monthly is that ÷ 12, weekly is ÷ 52. The hourly rate is £57,000 ÷ 52 ÷ 37.5 = £29.23.
Holiday follows the same fraction. Part-time staff get the same 5.6 weeks of statutory leave, measured in their own working days: 3 days a week gives 5.6 × 3 = 16.799999999999997 days. The holiday entitlement calculator gives your exact figure.
Whatever the sum says, the hourly rate must not fall below the National Minimum Wage for your age (£12.71 for 21 and over from 1 April 2026). Current rates are on gov.uk.
£57,000 pro rata: common questions
Is £57,000 pro rata the same as £57,000 a year?
No. "£57,000 pro rata" means £57,000 is the full-time salary and you get the share that matches your hours. On 25 hours against a 37.5-hour week you would earn £38,000 a year, not £57,000. You only get the full £57,000 if you work the full-time hours.
How much is £57,000 pro rata for 3 days a week?
£57,000 × 3 ÷ 5 = £34,200 a year. That is £2,850 a month or £658 a week before tax, assuming full time is 5 days.
Does pro rata pay change my hourly rate?
No. The hourly rate stays the same and only the number of paid hours changes. £57,000 for a 37.5-hour week is £29.23 an hour whether you work 37.5 hours or 20. Paying part-time staff a lower hourly rate for the same job may be unlawful less favourable treatment.
