How to Calculate Your National Insurance Contributions with a Paye Calculator

National Insurance (NI) contributions are a form of taxation that is deducted from an employee’s salary each month. It’s important to understand how much you need to pay in NI contributions so you can plan for your future. Fortunately, there is a handy tool that makes it easy to calculate your exact NI contribution rate—the PAYE calculator.

How the PAYE Calculator Works

The PAYE calculator is an online tool developed by Her Majesty’s Revenue and Customs (HMRC). It allows you to enter basic information about your income, such as the number of hours you work per week and your gross annual salary, and will then generate an estimate of how much must be paid in National Insurance contributions each month.

The calculator also takes into account any additional income sources, such as income from dividends or investments. This makes it easier for taxpayers to ensure they are paying the correct amount of tax each year. Additionally, it also offers helpful tips on how to reduce your taxes if necessary.

Understanding Your Contribution Rate

Once you’ve used the PAYE calculator, it’s important to understand exactly how much of your salary is going towards NI contributions every month. For example, employees earning more than £8,632 per year will be required to pay 12 per cent of their earnings towards NI. Those earning less than this amount will pay nothing at all. Employers must also make their own set of NI contributions for each employee who earns more than £166 per week or £702 per month. This helps fund state benefits such as maternity leave and sick pay as well as pensions and unemployment insurance.


The PAYE calculator is a great tool for understanding exactly how much money is being taken out of your salary in terms of National Insurance Contributions each month. Knowing this information can help you budget better for the future and ensure that you are not overpaying or underpaying in taxes throughout the year. With just a few clicks on the calculator, you can quickly get an accurate estimate of your contribution rate and start planning ahead!
