1. What is the Part-Time Salary Calculator?

This calculator estimates your take-home pay (net salary) for part-time work in the UK, accounting for income tax and National Insurance contributions based on your pro-rated salary.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Gross Pay — Your full-time equivalent annual salary
• Part-Time Hours — Your actual working hours per week
• Full-Time Hours — Standard full-time hours (typically 35-40)
• Income Tax — Calculated based on UK tax bands
• National Insurance — 12% on earnings between £12,570-£50,270

Explanation: The calculator first adjusts your gross salary to part-time equivalent, then deducts estimated taxes and NI contributions.

3. Importance of Accurate Salary Calculation

Details: Understanding your net pay helps with budgeting, financial planning, and comparing job offers. The calculation accounts for the progressive nature of UK tax and NI contributions.

4. Using the Calculator

Tips: Enter your full-time equivalent gross salary, your actual part-time hours, and standard full-time hours (default 40). The calculator will estimate your take-home pay after tax and NI.
