1. What is Pro Rata Salary?

Pro Rata salary refers to the proportional pay that part-time employees receive compared to full-time employees doing the same job. It's calculated based on the hours worked relative to full-time hours.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Full-Time Salary — Annual salary for full-time position
• Part-Time Hours — Hours worked by part-time employee
• Full-Time Hours — Standard full-time hours
• Income Tax — Estimated annual tax deductions
• National Insurance — Estimated NI contributions

Explanation: The formula first calculates the proportional salary based on hours worked, then deducts taxes and national insurance to get the net take-home pay.

3. Importance of Pro Rata Calculation

Details: Accurate pro rata calculations ensure fair compensation for part-time workers and help employers maintain equitable pay structures across their workforce.

4. Using the Calculator

Tips: Enter all values in GBP. Full-time salary should be the annual amount before tax. Hours should be weekly averages. Tax and NI should be estimated annual amounts.
