Please help explain how to calculate the overall transfer of social security enterprises 12%?

The payment standard of social security endowment insurance is: enterprises pay 20% of the payment base, and individuals pay 8% of the payment base. Part of the enterprise's payment goes into the overall planning, and part of the individual's payment goes into the personal account.

1. When social security is transferred across provinces, all individual contributions are transferred, and enterprise contributions are transferred to 12% of the payment base.

2. Suppose that 20% of the payment base of enterprises in 500 yuan is 100 yuan, then 60% of it is 60 yuan; This 60 yuan is exactly equivalent to 12% of 500 yuan (the "wage coefficient" you mentioned).
