The social security contribution ratio is 20%, 8%, etc. What is this 20%? Salary?

60% to 300% of the average salary of employees in the whole province (municipality directly under the central government and autonomous region) in the above years is used as the payment base. For example, last year, the province's average wage of 50,000 multiplied by 60% of the payment base was equal to 30,000. The 20% you want is 20% of 30000. There are 20% and 8% in the endowment insurance, which means that the employer is responsible for paying 20% and the individual pays 8%.
