Pro Rata Salary Calculator
Turn a full-time salary into your part-time pay, and work out the holiday you're entitled to for the hours you work.
A job advertised at £30,000 full-time for 37.5 hours a week, worked 3 days a week for 22.5 hours:
- 22.5 ÷ 37.5 = 0.6 FTE (full-time equivalent)
- £30,000 × 0.6 = £18,000 a year, which is £1,500 a month
- The hourly rate stays the same as full-time: about £15.38 an hour
- With 33 days' full-time holiday including bank holidays: 33 × 3 ÷ 5 = 19.8 days
The statutory minimum for a 3-day week is 16.8 days (5.6 weeks × 3 days), so 19.8 days is above it. For take-home pay after tax and National Insurance, put the pro rata salary into the take home pay calculator.
What does pro rata salary mean?
Pro rata means in proportion. A pro rata salary is the full-time salary scaled down to the hours you actually work. A £30,000 full-time job worked for 3 days out of 5 pays £18,000 pro rata.
How do I calculate a pro rata salary?
Divide your contracted hours by the full-time hours, then multiply by the full-time salary. For example, 22.5 hours out of a 37.5 hour week is 0.6 of full time, so a £30,000 salary becomes £18,000.
How much holiday do part-time workers get?
Everyone gets at least 5.6 weeks of paid holiday a year. For someone working 3 days a week that is 16.8 days, which can include bank holidays. If your employer gives full-time staff more than the minimum, your share should be pro rata too.
Do part-time workers get bank holidays?
There is no automatic right to bank holidays off, but part-time workers must not be treated less favourably. The fair approach is to pro rata the bank holidays along with the rest of the entitlement, so part-timers don't lose out when bank holidays fall on days they don't work.
