The gap between social security 15 and 20 years is introduced.

1. The pension is calculated on the basis of payment base, payment period, individual account fund balance and the average monthly salary of employees in the previous year.

2. The payment period of 20 years in personal account is 5 years longer than that of 15 years, so the fund balance in personal account is 5 years longer.

3. For example, our average payment base is 4,000 yuan per month, so the fund credited to personal account every month is 320 yuan, which is 3,840 yuan per year, which is 1.92 million yuan in five years, that is to say, compared with 20 years, personal account will be 1.92 million yuan more. If you retire at the age of 60, your personal account pension will be more than one month 138 yuan.

4. When calculating the basic pension, the payment period is also an important factor. If the calculation base of the annual basic pension is 60 yuan, then the payment 15 is the monthly 900 yuan, and the payment for 20 years is the monthly 1200 yuan, which means that the basic pension in 300 yuan is increased every month, and the personal account pension is increased by 438 yuan every month. The higher the payment base, the higher the proportion of basic pension and personal account pension will increase. Under normal circumstances, it is common that the pension will increase by about 100 yuan for each additional payment period.
