UK National Insurance Calculator 2024/2025: Guide to NI & Tax

Confused about your National Insurance Contributions (NICs) and take-home pay? Our UK National Insurance Calculator is the simplest way to understand your finances for the 2024/2025 tax year. Whether you're a salaried employee or self-employed, our tool provides a clear breakdown of what you pay and why.

Why Use an NI & Tax Calculator?

Navigating the complexities of the UK tax system can be challenging. From Income Tax to Class 1 and Class 4 National Insurance, the rules and rates can seem daunting. A reliable calculator helps you:

  • Estimate Your Take-Home Pay: See your gross income, all deductions, and what you’ll actually receive.

  • Understand Your Contributions: Learn exactly how much you're contributing to your State Pension and public services.

  • Plan Your Finances: Make informed financial decisions by knowing your net income in advance.

  • Verify Your Payslip: Cross-reference your payroll deductions to ensure they are correct.

​

How Our Calculator Works

Our tool uses the latest rates and thresholds for the 2024/2025 tax year. It performs two different calculations based on your employment status:

​

For Employees: Your calculation includes both your own Class 1 (Primary) National Insurance contributions and your employer's Class 1 (Secondary) contributions. This gives you a complete picture of the total cost of your employment.

​

For Self-Employed Individuals: The calculator focuses on your Class 4 National Insurance contributions, which are based on your taxable profits (your income minus your business expenses). It also correctly applies the Personal Allowance for Income Tax, giving you an accurate net profit figure.

​

Key UK Tax & NI Thresholds (2024/2025)

Our calculator is up-to-date with the following official figures:

  • Personal Allowance: £12,570 (the amount of income you don't pay tax on)

  • Basic Rate of Income Tax: 20%

  • Self-Employed NI Rate: 6% on profits between £12,570 and £50,270
