How to calculate the late payment fee for personal social security?

Calculated by day, calculated by percentage.

1. If the employer fails to pay the social insurance premium in full and on time, the social insurance premium collection agency shall order it to pay within a time limit or make up the late payment fee, and from the date of default, an additional five ten thousandths of the late payment fee shall be charged on a daily basis.

2. The individual pays social security by himself, and the late payment fee is borne by the individual. The calculation method is: the late payment fee is equal to the social security fee payable in the current month multiplied by the number of days in arrears multiplied by five ten thousandths.
