NI is a system for funding state benefits – including the State Pension – whereby employees (including the self-employed) and employers pay part of their earnings to the government during their working life.
Broadly speaking, NI contributions (NIC) amount to 9-12% on annual earnings between approximately £8,600 and £50,000 and 2% on earnings higher than that, though the type of employment, age and other factors play a role in determining the exact NIC you need to pay.
