Questions
What does pro rata mean?
Pro rata means in proportion. A pro rata salary is the share of a full-time salary that matches the hours, days or months you actually work.
Is this before or after tax?
The result is a gross amount, before income tax and National Insurance. Your take-home pay will be lower.
How many hours is full time in the UK?
There is no single legal definition. Employers commonly use between 35 and 40 hours a week, so check your contract for the figure your employer uses.
How do I work out pay for part of a year?
Divide the months you work by 12 and multiply the full-year salary by that fraction. Working 4 months of a £36,000 job earns £36,000 × 4 ÷ 12 = £12,000.
