How a pro rata salary is worked out

A pro rata salary is the full-time salary multiplied by your hours and divided by the full-time hours.

On a £30,000 full-time salary with a 37.5-hour week, 22.5 hours a week pays £18,000.00 a year. Tax and National Insurance are then worked out on that pay, so you take home £16,479.60: 66% of the full-time take-home pay for 60% of the hours.
