In Fujian Fuzhou, if the social security base is 20,800, the amount of pension received after retirement is affected by multiple factors and calculated through specific formulas. The pension mainly consists of basic pension, individual account pension, and for some people, there may also be transitional pension. Generally speaking, a higher social security base like 20,800 usually leads to a relatively high pension amount, but the exact figure depends on details such as contribution years and personal account accumulation. Here's a breakdown:

1. Basic Pension:

• The formula is ​
  LaTex error
  .

• For example, if the provincial average wage of on - the - job employees in the year of retirement is ​
  M
  (in 2024, the pension calculation base in Fujian is 7776 yuan/month, and this value may change in different years), and the index of personal monthly average contribution wage is ​
  a
  (since the contribution base is 20800, assume the average wage of on - the - job employees in the province in that year is ​
  M
  , then the monthly contribution wage index ​
  =M​
  , and assume the arithmetic average of monthly contribution wage indexes over the years is ​
  a
  ), and the contribution years is ​
  n
  .

• The index - based monthly average contribution wage of the individual ​
  =M×a
  .

• The basic pension ​
  =(M+M×a)÷×n×1%=M(+a)n​
  . If ​
  M=
  , and assume ​
  a=
  (because 20800 is much higher than the average wage, this is just an assumption for illustration) and ​
  n=
  years, then the basic pension ​
  =×(+)×​=3499.2
  yuan.

2. Individual Account Pension:

• The formula is ​
  LaTex error
  .

• The individual account contribution amount is calculated as the contribution base (​) multiplied by the individual contribution ratio (​
  8%
  for the pension insurance individual part), that is, the monthly individual account contribution ​
  =×8%=
  yuan.

• Assume the contribution years is ​
  n
  years, and the individual account interest rate is ​
  r
  . The individual account cumulative storage amount ​
  A=i=∑n×​×(+r)n×−i
  (a compound - interest - based cumulative calculation).

• The 计发月 number is determined according to the retirement age. For example, if retiring at 60 years old, the 计发月 number is 139 months. If the individual account cumulative storage amount is calculated as ​
  A=
  yuan (hypothetical value after years of accumulation), then the individual account pension ​
  =​≈3597.12
  yuan.

3. Transitional Pension:

• This is applicable to those with deemed contribution years. The formula is ​
  LaTex error
  .

• If a person has ​
  m
  years of deemed contribution years, and the index - based monthly average contribution wage is ​
  M×a
  as calculated above, then the transitional pension ​
  =M×a×m×1.3%
  . For example, if ​
  M=
  , ​
  a=
  , and ​
  m=
  years, then the transitional pension ​
  =×××1.3%=1010.88
  yuan.

In conclusion, the pension amount for those with a social security base of 20800 in Fuzhou needs to be calculated accurately based on specific personal data such as actual contribution years, deemed contribution years, and personal account storage amount. You can consult the local social security department for more accurate calculation results based on your own situation.
