How much pension can I get every month after paying social security 15 years retirement in Chengdu?

Social security has been paid for 15 years, mainly because you can get a pension after retirement. The calculation formula of pension is: monthly pension = basic pension+personal account pension. Basic pension = average monthly salary of local employees in the previous year when I retire ×20%, and personal account pension = deposit in my account ÷ 120. When the cumulative payment period is 15 years, if you retire at the age of 65, you can still receive a pension of about 20 years (provided that you live to 85 years old). Based on this calculation, the length of time you can receive a pension is 20× 12 months =240 months. Legal basis: Article 16 of the Social Insurance Law of People's Republic of China (PRC) stipulates that individuals who have participated in the basic old-age insurance will receive the basic old-age pension on a monthly basis if they have accumulated contributions for fifteen years when they reach the statutory retirement age. Individuals who participate in the basic old-age insurance and pay less than fifteen years when they reach the statutory retirement age can pay for fifteen years and receive the basic pension on a monthly basis; Can also be transferred to the new rural social endowment insurance or urban residents' social endowment insurance, enjoy the corresponding pension insurance benefits in accordance with the provisions of the State Council.
