1. What is Pro Rata Salary?

Pro Rata salary refers to the proportion of a full-time salary that a part-time employee would earn. It's calculated based on the number of hours worked compared to full-time hours.

2. How Does the Calculator Work?

The calculator uses the UK government approved formula:

Where:

• \( \text{Gross Pay} \) — Annual salary before deductions
• \( \text{Part-Time Hours} \) — Hours worked per week
• \( \text{Full-Time Hours} \) — Standard full-time hours per week
• \( \text{Income Tax} \) — Annual income tax amount
• \( \text{National Insurance} \) — Annual NI contributions

Explanation: The equation first calculates the proportional salary, then subtracts taxes and national insurance to get the net pay.

3. Importance of Pro Rata Calculation

Details: Accurate pro rata calculations ensure fair pay for part-time workers and help employers budget correctly for staffing costs.

4. Using the Calculator

Tips: Enter all values in GBP. Full-time hours are typically 35-40 hours/week in the UK. Ensure part-time hours don't exceed full-time hours.
