In Anhui Chizhou, if the social security base is 19,500, the amount of pension received is calculated as follows:

1. Determine the components of the pension:

• The pension mainly consists of two parts: basic pension and individual account pension. In some cases, for those who meet specific conditions (such as having a certain length of service before the implementation of the pension system reform in 1996), there may also be a transitional pension. However, since the information in the question does not indicate relevant conditions, we mainly focus on the basic pension and individual account pension here.

2. Calculate the basic pension:

• The formula for calculating the basic pension is: ​
  (provincial average wage of on - the - job employees in the previous year+personal indexed average wage of paid contributions)÷×payment years×1%
  .

• Assuming the provincial average wage of on - the - job employees in the previous year is ​
  A
  (not given in the question, we can't get an exact value. For the sake of illustration, if we assume ​
  A=
  yuan, this value is only for example and may not conform to the actual situation in Chizhou). The personal indexed average wage of paid contributions is 19,500 yuan (the given social security base).

• Suppose the payment years is ​
  n
  years. Then the basic pension ​
  P​=((A+)÷)×n×1%
  . For example, if ​
  n=
  years and ​
  A=
  yuan, ​
  P​=((+)÷)××1%=(÷)×0.3=
  yuan.

3. Calculate the individual account pension:

• The formula for calculating the individual account pension is: ​
  individual account balance÷monthly calculation and distribution number
  .

• The individual account balance is accumulated through personal contributions over the years. The personal contribution rate for pension insurance is usually 8% of the social security base. So the monthly personal contribution amount is ​
  ×8%=
  yuan.

• Suppose the payment period is ​
  n
  years (in months, ​
  n
  months). The individual account balance ​
  B=×n
  (ignoring interest for simplicity). The monthly calculation and distribution number is related to the retirement age. For example, if retiring at 60 years old, the monthly calculation and distribution number is 139.

• If ​
  n=
  years, the individual account balance ​
  B=××=
  yuan. Then the individual account pension ​
  P​=÷≈4040.29
  yuan.

4. Total pension amount:

• The total pension ​
  P=P​+P​
  . Continuing with the above example, ​
  P=+4040.29=7865.29
  yuan.

It should be noted that the above calculations are based on assumptions due to the lack of some key information such as the provincial average wage of on - the - job employees in the previous year and the actual payment years. In practice, it is recommended to consult the local social security department for a more accurate calculation of the pension amount.
