In Zhejiang Hangzhou, if the social security base is 12,400 yuan, the specific amount received varies for different social security benefits:

1. Pension:

• Basic pension: It is calculated based on factors such as the average monthly wage of on - the - job employees in the province in the previous year when meeting the pension - receiving conditions and the personal index - linked average contribution wage. Suppose the average monthly wage of on - the - job employees in the province in the previous year is ​
  A
  yuan, and the personal average contribution - wage index is ​
  B
  . The formula for the basic pension is ​
  (A+A×B)÷×contributionyears×1%
  . For example, if the contribution years are 15 years, and assuming ​
  A=
  yuan and ​
  B=
  (when the contribution base is 12,400 yuan, the contribution - wage index may be close to 1 in some cases), the basic pension is ​
  (+×)÷××1%=
  yuan.

• Personal account pension: It is calculated by dividing the personal account storage amount by the pension - receiving age - corresponding calculation months. The personal account storage amount is accumulated from the individual's monthly contribution. If the individual contributes 8% of the contribution base to the pension every month, that is, ​
  ×8%=
  yuan per month. Suppose the contribution period is 15 years (​
  ×=
  months), and the total contribution to the personal account is ​
  ×=
  yuan. If retiring at the age of 60 (the corresponding calculation months are 139 months), the personal account pension is ​
  ÷≈1284.6
  yuan. The total pension is the sum of the basic pension and the personal account pension, which is approximately ​
  +1284.6=2484.6
  yuan in this example. However, this is a rough estimate, and the actual amount is subject to the real data of the average wage in the province and other factors.

2. Medical insurance:

• The amount reimbursed for medical expenses is related to the reimbursement ratio and the deductible line. When the contribution base is 12,400 yuan, the amount credited to the personal medical insurance account will be relatively high. The unit contribution rate for medical insurance (including maternity insurance) is 9.5%, and the individual contribution rate is 2%. The amount credited to the personal medical insurance account is calculated based on the individual's contribution and part of the unit's contribution. The individual's monthly contribution is ​
  ×2%=
  yuan. Part of the unit's contribution will also be credited to the personal account according to certain rules, which can be used for purchasing medicines in designated pharmacies, outpatient expenses, etc.

3. Unemployment insurance:

• The amount of unemployment insurance benefits is related to the contribution period and the local minimum wage standard. Generally, the longer the contribution period and the higher the contribution base, the more favorable the calculation of unemployment insurance benefits. If the contribution base is 12,400 yuan, the amount of unemployment insurance premiums paid is relatively high. Assuming the contribution period is 5 years, according to the local unemployment insurance benefit calculation method (for example, 80% of the local minimum wage), if the local minimum wage is 2000 yuan, the monthly unemployment insurance benefit may be ​
  ×80%=
  yuan. But the specific amount is subject to local policies.

4. Work - related injury insurance and maternity insurance:

• For work - related injury insurance, the employer pays the premium, and the individual does not pay. When an employee suffers a work - related injury, the compensation amount is determined according to the degree of work - related injury and the relevant compensation standards.

• For maternity insurance, the employer pays the premium at a rate of 0.6% (included in the 9.5% of medical insurance contribution rate). Female employees can enjoy maternity leave benefits, maternity medical expenses reimbursement, etc. The specific amount of maternity leave benefits is calculated based on the average wage of the employer in the previous year in principle. If the average wage of the employer is related to the high contribution base of 12,400 yuan, the maternity leave benefits may be relatively high.

In general, when the social security base in Hangzhou is 12,400 yuan, the amount of various social security benefits is relatively high, which can provide better social security protection for individuals. However, the actual amount received is subject to specific local policies, contribution years, and other factors. It is recommended to consult the local social security department for accurate information.
