Calculate Your Pro Rata Salary
Enter the full-time salary and your working hours to calculate your pro rata salary.
What is Pro Rata Salary?
Pro rata salary is a way of calculating part-time pay based on the full-time equivalent salary. It ensures that part-time workers are paid fairly in proportion to their working hours compared to full-time employees.
How Pro Rata Calculation Works
The formula for calculating pro rata salary is:
Pro Rata Salary = (Full-Time Salary × Part-Time Hours) ÷ Full-Time Hours
Example Calculation
If a full-time role pays £35,000 for 40 hours per week, and you work 20 hours per week:
- Full-Time Salary: £35,000
- Full-Time Hours: 40
- Part-Time Hours: 20
- Pro Rata Salary: (£35,000 × 20) ÷ 40 = £17,500
