My social security is paid to 550 yuan every month. The company said that I bought social security 1000 instead of 1200. My salary is 1000 minus 147 yuan, right?

I'll provide you with a way to calculate for yourself. The most important thing is to know your contribution base, including pension and medical care. If the salary is 1500, you pay 8%, which is 120, which is pension and medical care. If you participate in comprehensive medical insurance, the payment base is 2336, and you pay 2%, which is about 46, then you need to bear 166. This is the standard of Shenzhen. Look at your standards and you can figure it out for yourself.
