It is sometimes spelled pro-rata, but this is technically a misspelling of the Latin phrase. In North American English this term has been vernacularized to prorated.
if you are paid pro rata it means that you do not work full time and your pay is calculated down for the hours you work so for example full time = 30 hours, pay = Â£100, you work 15 hours your pro rata pay is Â£50 hope that makes sense.
