How it works
Employees pay Class 1 National Insurance at 8% on earnings between Β£12,570 and Β£50,270 a year (Β£1,048 to Β£4,189 a month), and 2% above that.
Employers pay 15% National Insurance on earnings above Β£5,000 a year. Many small businesses can claim the Β£10,500 Employment Allowance to reduce their bill.
This calculator works on the annual figures and divides by 12 or 52, which matches payroll for a regular, steady salary.
