# Calculating Pro-rata Annual LEave

Can anyone help me to work out my owed AL please (my maths is terrible and each time I get a different answer!)
It is complicated as I work part time and my hourse changed a while back.
AL runs from 01 April each year.
My 2011 - 2012 allotment I would get 27 days (pro rata and excl bank hols)

A) 04.07.2011 - 22.1.2012 I worked 30 hours per week.
B) 23.1.2012 - 31.3.2012 I worked 33.5. hours per week. .

My 2012 - 2013 allotment I would get 29 days (pro rata and excl bank hols)

C) 01.04.2012 - 24.08.2012 I worked 33.5 hours

Please will some maths whizz out there tell me how much I am owed for A B and C and let me know how it was worked out? THANKS SO MUCH !

 You worked about 3/4 of a 40 hour week. You'd be entitled to 3/4 of leave entitlement, about 20 or 21 days 15:32 Mon 30th Jul 2012 Question Author Thanks sandy. I need the exact hours tho (and how this was calculated)as I'm leaving my job and I need to work out any hours owed. 15:34 Mon 30th Jul 2012 Question Author And to be even more fussy- --- preferably the seperate numbers for A. B. C. Of the question...., thanks in advance to anyone who can assist 15:36 Mon 30th Jul 2012 A: 9 weeks out of 52 gives 29/52 x 27 days = 15.0577 days B: 9 weeks out of 52 gives 9/52 x 27 days = 4.6731 days C: 21 weeks out of 52 gives 21/52 x 29 days = 11.7115 days The employer will probably just add up the days (ignoring the difference in hours per week over the two contracts), so that's 31.4423 days. Otherwise you need to multiply by 15.0577 by the average number of hours per working day for period A (which I don't know because you've not said how the 30 hours were distributed), 4.6731 by the average number of hours per day for period B, 11.7115 by the average number of hours per day for period C, and add your answers together to get the total number of hours due to you. Then divide by the number of hours per day you currently work (on average) to convert the figure to days. Chris 19:20 Mon 30th Jul 2012
