How to calculate the transfer from comprehensive insurance to social security?

Legal analysis: comprehensive insurance for foreign employees is gradually transformed into urban social insurance. Units can choose to turn all of them into urban insurance at one time, or they can choose to apply the five-year transition plan, gradually increase the proportion of payment, and pay new three insurances (pension, medical care, work injury). At present, most units choose the latter.

Legal basis: Article 4 of the Social Insurance Law of People's Republic of China (PRC) * * * Employers and individuals in People's Republic of China (PRC) pay social insurance premiums according to law, and have the right to inquire about payment records and personal rights and interests records, and ask social insurance agencies to provide social insurance consultation and other related services. Individuals enjoy social insurance benefits according to law and have the right to supervise the payment of their own units.
