This guide will walk you through everything you need to know about the National Insurance Calculator, how it works, and the benefits of using it.

2. How to Use

Using a National Insurance Calculator is straightforward. Here’s how to do it:

1. Gather Your Information: Before using the calculator, you’ll need to have the following details handy:
   • Your earnings or income
   • Your employment status (self-employed or employed)
   • Any other applicable deductions or benefits
2. Input Your Data: Enter your earnings into the calculator along with your employment status. Most calculators will guide you through the process step-by-step.
3. Calculate: Click the calculate button to receive an estimate of your National Insurance contributions.
4. Review Results: Examine the breakdown of your contributions based on your earnings, which will help you plan your finances.

3. Formula

The formula used in calculating National Insurance contributions varies based on whether you’re employed or self-employed.

• For Employees:

  NI Contributions = (Earnings – Lower Earnings Limit) x Rate

• For Self-Employed:

  NI Contributions = Class 2 + Class 4 Contributions

  Class 2: A flat rate for profits over a certain threshold

  Class 4: A percentage of profits over a specific limit

4. Example Calculation

To illustrate how the calculations work, let’s consider an example:

• Employee:

  For a gross income of £30,000, with a primary threshold of £9,568 and a rate of 12%

  NI Contributions = (£30,000 – £9,568) x 0.12 = £2,466.30

• Self-Employed:

  For a profit of £40,000

  • Class 2: £3.15 per week for profits over £6,725
  • Class 4: (40,000 – 9,569) x 9% = £2,748.99

  Total NI Contributions = Class 2 + Class 4 = £164.80 + £2,748.99 = £2,913.79
