hook, there is a proportion, the unit pays part and pays part by itself. Formula: Pre-tax monthly salary × 1% to 12 %× 2 (unit+individual). For example, if the pre-tax monthly salary is 5, and the provident fund rate is 1%, then the monthly provident fund = 5,× 1 %× 2 = 1,, with 5 for the unit and 5 for the individual.
