How much can I get more than others by paying social security for three more years?

Hello, dear, how much more can I get by paying social security for three years? Of course, if you pay more social security, you will get more pension. Pensions include basic pensions and personal account pensions. The calculation formula of the two is: basic pension = (average social wage of last year x average social insurance payment index+average social wage of last year) ÷2x (payment period x 1%) personal account pension = personal account fund balance ÷ 139 (male) 195 (female). Therefore, the calculation of basic pension. Different payment years will inevitably lead to different pensions. Social insurance follows the principle of paying more and getting more. The more you pay, the longer the payment period, and the more pension you can get after retirement. Although the contribution of 18 is a little more than that of 15, it can only maintain the most basic life after retirement. In order to live comfortably after retirement, it is suggested to increase the payment period as much as possible.
