1. What is Net Pay?

Net pay is the amount of money you take home after all deductions have been subtracted from your gross salary. In the UK, these deductions typically include Income Tax, National Insurance contributions, student loan repayments, and pension contributions.

2. How the Calculator Works

The calculator uses the following formula:

Where:

• Gross Pay — Your total salary before any deductions
• Income Tax — Deducted based on your tax code and income level
• National Insurance — Contributions to state benefits
• Student Loan — Repayments if you have a student loan (Plan 1, 2, or 4)
• Pension Contributions — Workplace or personal pension deductions

3. UK Salary Deductions Explained

Income Tax: In the UK, income tax is progressive with different rates for different bands of income (Personal Allowance, Basic Rate, Higher Rate, and Additional Rate).

National Insurance: Paid by both employees and employers, funding state benefits including the NHS and state pension.

Student Loans: Repayments begin when your income exceeds the threshold for your repayment plan (currently £27,295 for Plan 2).

Pension: Workplace pensions are automatically enrolled for eligible employees, with minimum contributions set by law.

4. Using the Calculator

Tips: Enter your gross annual salary and all known deductions. For student loans and pension, enter 0 if not applicable. The calculator will show your estimated take-home pay.
