How much is national insurance?

How much youll pay in National Insurance depends on what kind of National Insurance youre paying. Weve summarised each of the national insurance classes below.

Class 1 National Insurance Rates (2021/22)

As an employee, you begin paying National Insurance when you earn over £184 a week in 2021/2022.

The amount of National Insurance you pay depends on how much you earn. Its made up of:

12% of your weekly earnings between £184 and £967 (2021/22)

2% of your weekly earnings above £967.

On 6 April 2022, Class 1 NICs will go up by 1.25% to cover the costs of social care and help deal with the NHS backlog.

Class 2 National Insurance rates (2021/22)

Self-employed people pay Class 2 weekly contributions at a flat rate of £3.05 and are set for 2021-2022. If your profits are over £6,515 you need to pay them every week (or partial week) youre self-employed in a tax year.

If you earn less than £6,515, paying NICs is voluntary but will still help build up your entitlement to the state pension.

It will tell you:

  • What National Insurance payments or credits you have for the tax years requested;
  • What class of contributions you made;
  • If there are any payment or credit gaps (years with payment gaps may not count towards your State Pension);
  • Whether you can pay voluntary contributions to fill the gaps and how much it will cost.


However, it won’t tell you how much state pension you’re entitled to.

You can also call the National Insurance helpline on 0300 200 3500 to request a statement.

How do I make up a shortfall in my National Insurance Contributions?

If you don’t pay National Insurance contributions, you might want to pay Class 3 voluntary contributions to boost your pension entitlement.

In 2021-22, Class 3 contributions are payable at a weekly rate of £15.40. This is the maximum you can pay each week. Rates for previous tax years will be different. 

You might not always be able to pay Class 3 contributions for a tax year.

  • you can make payments towards any gaps
  • how much you’ll need to pay
  • you will benefit from making any voluntary National Insurance contributions.
