Pro Rata hours calculation help

Glitterysquirrel

Hello,


I currently work term time only (39 weeks a year). My salary is paid in equal monthly amounts and is based on 18 hours a week when spread across the year.


I am having problems with working out how many hours I need to work a week to ensure I am not working more than I get paid.


My wage used to be based on 16.2 hours per week, which meant I worked 18.75 hours a week term time, but when it was changed to the above no one in HR seemed to know how to work out how many hours I should now be working.


I would be really grateful to anyone who can help , thanks.

52.2 weeks a year minus 5.6 weeks of statutory holiday is 46.6 weeks work.
46.6 weeks at 18 hours each is 838.8 hours of work
838.8 divided over 39 weeks is 21.5 hours a week. (And an extra 18 minutes sometime over the year.)

Or an alternative way of calculating, which is to your advantage (perhaps the difference is because your holidays are more generous than the legal minimum).

Old hours 16.2, new hours 18 so this is an increase by 18/16.2
Increase the hours you work in proportion.
18/16.2 x old working week of 18.75 = 20.83 hours in new working week or 20 hours 50 minutes.

Thanks theoretica for your answers. Now I have seen how to work it out it seems so simple.
