In Jiangxi Jiujiang, if the social security base is 14,200, the amount one can receive mainly depends on several aspects:

1. Pension calculation:

• Basic pension: It is related to the pension calculation base, personal average contribution index, and cumulative contribution years. For example, if the pension calculation base is assumed to be ​
  A
  (the specific value needs to refer to the local standard of the year), the personal average contribution index is ​
  B
  (if the contribution base is 14,200, the corresponding index can be calculated according to the local average wage ratio), and the cumulative contribution years is ​
  C
  years. The formula for the basic pension is ​
  A×(+B)÷×C×1%
  .

• Personal account pension: It is calculated by dividing the balance of the personal pension account by the number of pension distribution months corresponding to the retirement age. If the balance of the personal account is ​
  D
  yuan, and the retirement age is 60 years old (the corresponding number of distribution months is 139 months), then the personal account pension is ​
  D÷
  .

• Transitional pension: This part is mainly for those with working years before the establishment of the personal account. It is calculated based on factors such as the 视同缴费指数，pension calculation base, 视同缴费 years, and transitional coefficient. The specific formula is more complex and varies by region. For example, if the 视同缴费 index is ​
  E
  , the pension calculation base is ​
  A
  , the 视同缴费 years is ​
  F
  years, and the transitional coefficient is ​
  G
  , then the transitional pension is ​
  E×A×F×G
  .

2. Unemployment insurance benefits: The amount of unemployment insurance benefits is related to the cumulative contribution years. For example, if the cumulative contribution years are between 1 - 2 years, 3 months of unemployment insurance benefits can be received; if between 2 - 3 years, 6 months can be received, and so on. The specific amount is generally calculated based on a certain proportion of the local minimum wage.

3. Medical insurance benefits: After paying medical insurance, one can enjoy medical expense reimbursement during the insured period. The reimbursement ratio and scope vary according to different levels of medical institutions and medical expenses. For example, the reimbursement ratio in first - level hospitals may be higher than that in third - level hospitals.

In general, to accurately calculate the amount of social security benefits in Jiangxi Jiujiang with a social security base of 14,200, it is necessary to comprehensively consider personal contribution years, retirement age, local wage standards, and relevant policy regulations. It is recommended to consult the local social security department for specific details.
