Question: how national insurance contributions are calculated?
Answer: If you're an employee, you'll need to pay Class 1 NICs on your earnings. ... you pay National Insurance contributions if you earn more than £183 a week for 2020-21. you pay 12% of your earnings above this limit and up to £962 a week for 2020-21. the rate drops to 2% of your earnings over £962 a week.
