There are upper and lower limits, depending on the actual situation in each region.

(two) the wage income of employees is lower than 60% of the local average wage of employees in the previous year, with 60% of the local average wage of employees in the previous year as the payment base;

(3) If the employee's salary is between 300% and 60%, it shall be declared according to the facts. When it is impossible to determine the wage income of employees, the payment base shall be determined according to the local average wage of employees in the previous year published by the local labor administrative department. Social security will regularly check the base every year (March or July, in different places), and declare a new base according to the average monthly salary of employees in the previous year.

Everyone's social security amount is different, which is determined according to individual wages and local average wages.
