Answers. Best Answer: well per annum means per year. Pro rata means at that rate. So for example,if you work the full 37.5 hours per week for the full year you will earn Â£20,000 per annum, however if you end up working half of that you would earn Â£10,000.So if you only work 3months that is a 1/4 of Â£20,000, so you would earn Â£20,000/4 = Â£5,000.Source(s):ey, Can anyone help me understand what this means. If your salary will be Â£20,000 per annum pro rata what does this means? This is for full time work, 37.5 hrs per week, but only for 3 months.
