Refers to the sum of the provident fund paid by the employer for the employees of the unit and the housing provident fund paid by the employees of the employer. Together, it is called bilateral provident fund, and the specific amount is calculated according to the proportion of individual wages.

Simply put, it is the total amount remitted by the provident fund, which mainly includes all the amounts paid by individuals and units. The deposit ratio of provident fund is generally not less than 5% or 12%, which varies from region to region and from unit to unit. Therefore, the maximum bilateral provident fund needs to be determined according to the specific situation.

The deposit base of housing provident fund refers to how much provident fund should be paid according to this figure. Generally, it is the average monthly salary of the previous year. For example, last year's average salary was 2000, and this year's deposit base was 2000, according to the standard of 12 for individuals and units. This year, the individual is in 240 yuan every month, and the unit is in 240 yuan. The monthly deposit base of housing provident fund shall not exceed 3 times the average monthly salary of employees in the previous year announced by the statistical department of the city where the employees are located. If the monthly salary base of employees in the previous year is 3 times higher than the average monthly salary of employees in the previous year, the deposit base shall be approved according to 3 times the average monthly salary of employees in the previous year.
