How to calculate pro rata salary
- Take the full-time salary in the advert.
- Divide your weekly hours by the full-time hours (often 37.5).
- Multiply the two. By days it's the same: salary × days ÷ 5.
"Pro rata" means the advertised figure is the full-time equivalent. You're paid your share of it, and you get the same share of holiday: 5.6 weeks a year, so 16.8 days if you work 3 days a week.
Full time, £66,000 takes home £4,069.78 a month. See £66,000 after tax →
