How to calculate the money paid before the social security downgrade?

Downshift calculation, payment base, personal account.

1. Downgrading calculation: the insured can choose to lower the social security level, but the previous payment level will not be cleared, but will be calculated according to the new level.

2. payment base: lowering the social security level will affect the payment base, thus affecting the payment amount. In the past, social security was paid according to the first file, but this time it was reduced to the second file, so the payment base will be calculated according to the base of the second file, and the corresponding payment amount will also be reduced.

3. Personal account: Personal account will not be cleared or reduced due to the reduction of social security level, and the social security fees paid before will still be credited to personal account.
