In Anhui Huaibei, if the social security base is 9300, the amount of pension received is calculated as follows:

1. Basic pension: The formula is ​
   (Average monthly wage of on - the - job employees in urban units in the region in the previous year when the insured retires+Indexed average monthly contribution wage of the individual)÷×Contribution years×1%
   . However, without knowing the average monthly wage of on - the - job employees in the region in the previous year when retiring and the contribution years, it is difficult to calculate accurately. For example, if the average monthly wage of on - the - job employees in the region in the previous year when retiring is ​
   x
   yuan and the contribution years is ​
   y
   years, the basic pension ​
   =(x+​)×y×1%
   .

2. Personal account pension: The formula is ​
   Retirement personal account balance÷Calculation and distribution months corresponding to the retirement age of the individual
   . The personal account balance is accumulated through monthly contributions. Assuming the contribution rate to the personal account is 8% of the contribution base, the monthly contribution to the personal account is ​
   ×8%=
   yuan. But we don't know the contribution years and the retirement age (the calculation and distribution months are 195 for 50 - year - old retirement, 170 for 55 - year - old retirement, and 139 for 60 - year - old retirement), so we can't calculate the specific amount of the personal account pension. For example, if the contribution years is ​
   y
   years, the personal account balance is ​
   ××y
   yuan. If the retirement age is 60 years old, the personal account pension ​
   =××y​
   .

3. Transitional pension (if applicable): For those who started working before the mid - 1990s and have no personal account pension, there will be a transitional pension. It is calculated as about 1.3% of the social average wage base per year. But specific circumstances vary from person to person, and relevant work - starting time and other information are needed for accurate calculation.

In general, accurately calculating the pension amount requires knowing more information such as the average monthly wage of on - the - job employees in the region in the previous year when retiring, contribution years, and retirement age. It is recommended to consult the local social security department for specific inquiries.
