Is medical insurance and social security based on basic salary?

At first, it was paid according to the social security base reported to you by the company. For example, your monthly income is 6000 yuan, but the social security base reported by the company is based on the local minimum social security base (in Shanghai, for example, the minimum social security base for 20 17 years is 3902), then this percentage is calculated according to the standard of 3902. If the monthly income is less than 3902, it will still be paid according to 3902.

Every April, the social security base will be adjusted. Generally speaking, it will be measured according to the actual salary level in your bank card. For example, if you pay 4000 in the bank and 2000 in cash every month, the social security base will basically become 4000, and the subsequent social security payment will be calculated according to 4000.
