In 2024, the monthly standard of social insurance contribution base in Xiangyang, Hubei is 6948 yuan. The contribution base of 5800 yuan is not an exact match for a specific contribution grade. However, by comparing with the common contribution grade settings (usually set at intervals such as 60%, 70%, 80%, 90%, 100%, 150%, 200%, 250%, 300% of the base), we can roughly estimate its range:

1. Calculation of common contribution grade bases:

• If calculated as 60% of the base, it is ​
  ×60%=4168.8
  yuan.

• If calculated as 70% of the base, it is ​
  ×70%=4863.6
  yuan.

• If calculated as 80% of the base, it is ​
  ×80%=5558.4
  yuan.

• If calculated as 90% of the base, it is ​
  ×90%=6253.2
  yuan.

2. Judgment of the grade corresponding to 5800 yuan: Since 5800 yuan is higher than the base calculated at 80% (​
   5558.4
   yuan) and lower than the base calculated at 90% (​
   6253.2
   yuan), the contribution base of 5800 yuan is between the 80% - grade and the 90% - grade.

It should be noted that the above is only an analysis and judgment based on general rules. For the exact contribution grade corresponding to the contribution base of 5800 yuan, it is recommended to consult the local social security department or relevant agencies in Xiangyang. They can provide the most accurate and detailed information according to the local social security policy.
