40 pay social security, how many years, how much can you get at the age of 55?

Not sure. Since I was 40 years old, I have paid social security not only to 540 yuan every month, but also more and more every year, reaching 15 years. Pensions need to be judged according to specific circumstances. The minimum payment period of unit social security is 15, but the medical insurance included in social security needs to be paid for at least 20 years to enjoy the medical treatment after retirement. Social insurance is the most important part of the social security system.
