Paid for the weeks you work, and the holiday they earn.
Term-time only staff, such as teaching assistants and other school support staff, are paid for the weeks they work plus the holiday those weeks earn, spread across twelve equal monthly payments. Portion uses the NJC Green Book's advisory method, which many councils and schools follow.
A full-time, all-year worker has 260.71 working days a year and takes their leave out of them. A term-time worker's pay is their working days as a share of what is left. With 39 weeks and 36 days of full-time leave, that is 195 of 224.71 days, or 86.78% of the full-time salary, before the hours fraction is applied.
Enter the full-time holiday for the role, including bank holidays and any extra days, because every day of it changes the result. Your employer's method may differ, so check it against your contract.
The working for the figures above, line by line:
How do I work out a pro rata salary?
Divide your weekly hours by the full-time weekly hours to get your fraction, then multiply the full-time salary by it. 22.5 hours of a 37.5-hour week is 0.6, so £32,000 full time becomes £19,200. To go the other way, divide the part-time salary by the fraction.
What does pro rata mean?
In proportion. A pro rata salary is the full-time salary scaled to the hours you work: 22.5 hours of a 37.5-hour week is 60%, so a job advertised at £32,000 pro rata pays £19,200 a year. Adverts give the full-time figure so part-time roles can be compared, which is why the number in the advert is not what you are paid.
How is part-time holiday worked out?
Portion turns the full-time allowance into hours on a five-day full-time week, then applies your fraction. 28 days of 7.5 hours is 210 hours; at 0.6 that is 126 hours. Hours come first because a day means different things in different patterns: with uneven days, a Monday off can use more hours than a Friday.
What is the statutory minimum?
Almost all workers are entitled to 5.6 weeks of paid holiday a year, capped at 28 days. For a regular pattern that is 5.6 times your working week. Bank holidays can count towards it. Portion shows the figure for your week beside the allowance you enter. GOV.UK holiday entitlement.
Are bank holidays included?
That is your employer's call, and the contract should say. Tick the box if your allowance already includes them; otherwise pick your nation and year and Portion adds them pro rata as their own line. The counts come from GOV.UK, checked 19 September 2026. GOV.UK bank holidays.
Is the monthly figure my take-home pay?
No. It is the gross annual figure divided by twelve. The weekly and hourly figures use 52 weeks, for comparison. Tax, National Insurance, pension, bonuses and how your payroll actually splits the year are not included.
How is term-time pay worked out?
Tick Term time only and enter the weeks worked a year, usually 39 for school staff. Portion uses the NJC Green Book's advisory method, which many councils and schools follow: you are paid for the weeks you work plus the holiday those weeks earn, as a share of a full-time year of 260.71 working days. 39 weeks against 36 days of full-time leave comes to 86.78% of the year, paid in twelve equal instalments. Your employer's method may differ. NJC Green Book Part 4.12.
What about irregular hours or joining part way through the year?
Portion handles regular patterns, including term-time contracts that work the same weeks every year. Irregular-hours workers, and part-year workers with unpaid weeks, build up statutory holiday differently: at 12.07% of hours worked, for leave years from April 2024. Starting or leaving part way through a year is not covered. Use the GOV.UK calculator for those. GOV.UK holiday calculator.
Is this advice?
No. It is a calculator on the figures you type. Your contract and your employer's policy decide what you are paid and what holiday you get. Acas guidance is that part-day holiday can be rounded up but not down; Portion shows the exact hours and leaves the rounding to your employer.

The salary, the full-time hours, the holiday figures, the bank holiday choice and the hours for each day, plus the kept week, the term-time weeks and the full-time rate for an offer check if you have them.
