Reading job adverts
A listing that says “£30,000 pro rata” for a three-day week does not pay £30,000. At three days out of five it pays £18,000. Always ask what the full-time hours are, because 30 hours is 80% of a 37.5-hour week but only 75% of a 40-hour week.
Holiday entitlement is normally pro-rated in the same proportion as pay.
Questions people ask
How do I calculate pro rata for 3 days a week?
Multiply the full-time salary by 3 ÷ 5. A £40,000 full-time salary becomes £24,000.
Is the hourly rate lower for part-time staff?
It should not be. Pro rata means the same hourly rate for fewer hours, which is why the hourly result here does not change when you change your hours.
