In Jiangsu Huai'an, if the social security base is 9100, the amount of pension received after retirement is calculated based on multiple factors, and the approximate amount can be estimated through the following aspects:

1. Basic pension: It is related to factors such as the average wage of on - the - job employees in the province in the previous year when retiring, personal average contribution index, and cumulative contribution years. The formula is ​
   (+personalaveragecontributionindex)/2×contributionbase×cumulativecontributionyears×1%
   . Assuming the contribution base is 9100, if the personal average contribution index is 1 (for example), and the cumulative contribution years are 30 years, and taking the average wage of on - the - job employees in the province in the previous year as 8613 (the value in 2023 for reference), then the basic pension ​
   =(+)/2×××1%=2583.9
   yuan. But in fact, the personal average contribution index may vary according to actual contribution situations.

2. Personal account pension: It is calculated by dividing the cumulative balance of the personal account at the time of retirement by the pension calculation months. The personal contribution amount each month is ​
   ×8%=
   yuan. Suppose the contribution period is 30 years (360 months), and considering interest factors, if the cumulative balance of the personal account is 300,000 yuan at the time of retirement, and if retiring at the age of 60 (the pension calculation months are 139), then the personal account pension ​
   =÷≈2158.27
   yuan.

3. Transitional pension: Only "elderly people" who started working before 1996 and other people with deemed contribution years have this part. The calculation of the transitional pension is more complex, related to factors such as the deemed contribution index, contribution base, and deemed contribution years. Assuming the deemed contribution years are 10 years, the deemed contribution index is 0.8, and taking the average wage of on - the - job employees in the province in the previous year as 8613, and the transitional coefficient as 1.2%, then the transitional pension ​
   =0.8×××1.2%=826.85
   yuan.

The total pension is the sum of the basic pension, personal account pension, and transitional pension (if applicable). In the above example, the total pension ​
