1. What is Pro Rata Salary?

Pro rata salary is a calculation that adjusts a full-time salary to reflect part-time work. It ensures employees working reduced hours receive a fair proportion of the full-time equivalent salary.

2. How Does the Calculator Work?

The calculator uses the pro rata formula:

Where:

• Gross Pay — Annual full-time salary in GBP
• Part-Time Hours — Weekly hours worked
• Full-Time Hours — Standard weekly full-time hours
• Income Tax — Annual tax amount in GBP
• National Insurance — Annual NI contributions in GBP

Explanation: The calculation first determines the proportion of full-time pay based on hours worked, then deducts taxes and contributions.

3. Importance of Pro Rata Calculation

Details: Accurate pro rata calculations ensure fair pay for part-time workers and help employers comply with UK employment law. The results can be verified using the UK government's official salary calculator.

4. Using the Calculator

Tips: Enter all values in GBP. Full-time hours are typically 35-40 hours/week in the UK. For accurate results, use your actual tax and NI figures from your payslip or P60.
