In Anhui Fuyang, if the social security base is 13,500 yuan, it belongs to a relatively high - level payment range. Here's an analysis:

1. Determination of social security payment grades: Generally, social security payment bases in Fuyang are set as a percentage of the local average wage of employees in the previous year, and usually range from 60% to 300% of the average wage. These different percentages correspond to different payment grades. For example, in some common settings, there may be grades such as 60% (low - end grade), 80%, 100%, 150%, 200%, and 300% (high - end grade).

2. Calculation of corresponding grades for 13,500 yuan: In 2024, the upper limit of the social security payment base in Fuyang is 21,133 yuan/month, and the lower limit is 4,227 yuan/month. First, we need to know the local average wage of employees in the previous year. Suppose the average wage of employees in Fuyang in the previous year is ​

   yuan. The payment base of 13,500 yuan ​
   ÷x
   gives the percentage of the average wage it represents. If we assume that the average wage of employees in Fuyang in the previous year is about 7,000 yuan (this is a reference value for easy understanding, and the actual value is subject to official announcements), then ​
   ÷≈1.93
   , which is close to 200% of the average wage. So, if the local average wage is around this value, a payment base of 13,500 yuan is likely to be in the grade close to 200% of the average wage.

3. Impact on social security treatment: Paying at a base of 13,500 yuan means that the amount of social security contributions (such as pension insurance, medical insurance, etc.) will be relatively high. For pension insurance, when calculating the pension in the future, factors such as the payment base and payment years are considered. Paying at a higher base will increase the individual account amount, and in the end, the pension received will also be relatively more. For medical insurance, although the reimbursement ratio is not directly related to the payment base, a higher payment base may be related to a higher reimbursement ceiling in some cases.

In conclusion, a social security base of 13,500 yuan in Fuyang is at a relatively high payment level. Specific grade determination still needs to be combined with the local average wage data of employees in the previous year announced by the local social security department. It is recommended to consult the local social security agency for the most accurate information.
