1. What is the Part-Time Salary Calculator?

This calculator helps you determine your part-time net salary in the UK based on your full-time gross salary, working hours, and tax deductions. It accounts for the proportional reduction in hours and applies your tax and National Insurance contributions.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Part-Time Net Pay} = \left(\text{Gross Pay} \times \frac{\text{Part-Time Hours}}{\text{Full-Time Hours}}\right) - \text{Income Tax} - \text{National Insurance} \]

Where:

\( \text{Gross Pay} \) — Your annual full-time salary before deductions
\( \text{Part-Time Hours} \) — Hours you work per week in part-time role
\( \text{Full-Time Hours} \) — Standard full-time hours per week (typically 37.5)
\( \text{Income Tax} \) — Your annual income tax amount
\( \text{National Insurance} \) — Your annual National Insurance contributions

Explanation: The calculator first scales your gross pay proportionally to your working hours, then subtracts your tax and NI contributions.
