You need know the number of hours a full time employee for the company works to calculate your per annum salary.
If full time = 40 hrs then a 30 hour pro rata salary is 30/40 (or 3/4) of �14,536 i.e.
�10,902 pa gross.
This would "normally" equate to take home pay of
�178.72 per week.
If full time = 37 hrs then a 30 hour pro rata salary is 30/37 of �14,536 i.e.
�11,786 pa gross.
This would "normally" equate to take home pay of
�190.11 per week.
"Normally" is used to signify a personal tax code 522L and no deductions (pension etc.).
