1. What is Net Pay Per Month?

Net Pay (also known as take-home pay) is the amount of money an employee receives after all deductions have been taken from their gross salary. In the UK PAYE system, this includes Income Tax, National Insurance, and Pension contributions.

2. How Does the Calculator Work?

The calculator uses the standard UK payroll formula:

\[ Net\ Pay = \frac{Gross\ Annual\ Salary}{12} - (Tax + National\ Insurance + Pension) \]

Where:

\( Gross\ Annual\ Salary \) — Total yearly salary before deductions
\( Tax \) — Income tax calculated as percentage of monthly gross
\( National\ Insurance \) — NI contributions based on monthly gross
\( Pension \) — Pension contributions as percentage of monthly gross

Explanation: The calculator converts annual gross salary to monthly, then applies the specified percentage rates for each deduction to calculate the final take-home pay.

3. Importance of Net Pay Calculation

Details: Understanding net pay is crucial for personal financial planning, budgeting, loan applications, and ensuring you're being paid correctly according to UK tax laws and pension regulations.

4. Using the Calculator

Tips: Enter your gross annual salary in GBP, then input the applicable tax rate, National Insurance rate, and pension contribution rate as percentages. All values must be valid positive numbers.
