Shanghai social security payment base is generally determined according to employees' wages, but it will not exceed the upper and lower limits of the social security payment base. The upper and lower limit standards are usually determined according to 3% and 6% of the average wage of employees in local full-caliber urban units. In addition, the Shanghai social security payment base standard is generally adjusted in the middle and late of each year, usually from April to July. The specific criteria are: the reference level of the upper limit of social security payment base is 9339 yuan/month, so the upper limit of social security payment base in Shanghai is 2817 yuan/month (9339 yuan * 3%); The lower limit of the payment base continues the standard of 219, which is 4927 yuan/month. Note: The work-related injury payment ratio is determined according to the industry risk category of the unit, and the floating rate is implemented according to the employer's work-related injury insurance payment rate and the incidence of work-related accidents, and the payment ratio of each enterprise may be different.

Calculation method of Shanghai's old-age insurance base

Compared with the social average monthly wage, if your wage income is three times higher than the social average monthly wage, the payment base is calculated at three times the social average monthly wage, and the above part is not calculated as the payment base; If your salary income is lower than 6% of the average monthly salary, the payment base will be calculated at 6% of the average monthly salary.
