How to press calculate length social security?

Social security is not calculated by "length of service". Social security is calculated cumulatively according to the month of social security payment. There is a unified formula for social security pension. Because there is a lot of information, some information is not at hand, and some information has not happened yet, so it is difficult to calculate at the moment. To calculate the pension, you need to pay the social security time, how much, the average salary of the local society at that time, when to pay, when to retire, boys or girls. You need a receipt for every payment. So, collect your own receipts and local social security information.

Let's go back to "length of service". In the past, you only needed to work for a few years to calculate your retirement salary. Now it is a social security pension, and social security fees are usually paid. When retiring, according to the usual payment situation, the pension will be paid fairly in the environment of social endowment insurance payment. The present situation can be said to be very different from the past. Give a reference to the calculation formula of pension.
