How To Use The National Insurance Calculator
- Enter your salary and specify whether it is an annual or monthly figure.
- Choose employment status. This step is important because it informs the calculator about which National Insurance classes to apply.
- Click the 'Calculate' button once you're done, and you'll see your net salary and the National Insurance you're expected pay, all displayed on an annual, monthly, weekly, and daily basis.
Note: We will update this calculator in January with the new National Insurance rates
