the total amount of wages paid by individuals for one month when they pay the provident fund is multiplied by .8.

The amount that individuals need to pay for the provident fund at their own expense every month is their total salary multiplied by .8. For example, if the total salary is 5, yuan, they need to pay 5, times .8=4 yuan's provident fund at their own expense every month.

Provisions on the proportion of provident fund payment:

1. The proportion of housing provident fund payment shall not be less than 5% of the average monthly salary of employees in the previous year;

2. The upper limit of the deposit ratio is 12%, that is, the maximum amount shall not exceed 12% of the average monthly salary of employees in the previous year;

3. The individual contribution ratio should be equal to or higher than the unit contribution ratio;

to sum up, the amount of personal contribution to the provident fund is calculated according to the personal salary base and contribution ratio. Taking Beijing as an example, the contribution ratio of individuals and units is usually the same, and shall not exceed a certain proportion of the average monthly salary of employees in the previous year.
