If your social security base in Huai'an, Jiangsu is 6,600 yuan, here's an estimate of how much you can receive:

1. Pension calculation:

• Basic pension: The formula is ​
  Basic pension=Calculation base×(+Personal average contribution index)÷×Accumulated contribution years×1%
  . Assuming a contribution index of 1 (when the contribution base is the average salary), and if you contribute for 15 years, and taking the local pension calculation base as an example (for simplicity, assume it's 8,000 yuan, which may vary in reality), then the basic pension ​
  =×(+)÷××1%=
  yuan.

• Personal account pension: First, calculate the annual contribution to the personal account. For pension insurance, the individual contribution rate is 8%. So the monthly contribution to the personal account is ​
  ×8%=
  yuan, and the annual contribution is ​
  ×=
  yuan. After contributing for 15 years, the total amount in the personal account is approximately ​
  ×=
  yuan (ignoring interest for simplicity). If you retire at 60 years old, the pension calculation months are 139 months. Then the personal account pension ​
  =÷≈
  yuan.

• Total pension: The total pension is the sum of the basic pension and the personal account pension, which is approximately ​
  +=
  yuan. However, this is a rough estimate, and the actual amount may be affected by many factors such as the local pension calculation base, contribution years, and interest in the personal account.

2. Medical insurance account: The individual contribution rate for medical insurance is 2%. So the monthly contribution to the medical insurance account is ​
   ×2%=
   yuan. The funds in the medical insurance account can be used for outpatient medical treatment, purchasing medicines, etc.

3. Unemployment insurance: The individual contribution rate for unemployment insurance is 0.3%. The monthly contribution is ​
   ×0.3%=19.8
   yuan. In case of unemployment, you can receive unemployment benefits according to relevant regulations. The amount of unemployment benefits is related to the local minimum wage standard and the length of contribution.

4. Work - related injury insurance: The employer pays for work - related injury insurance, and the contribution rate varies according to different industries, generally ranging from 0.5% to 1.6%. Assuming a contribution rate of 0.8% for the employer, the employer's monthly contribution is ​
   ×0.8%=52.8
   yuan. If you suffer a work - related injury, you can enjoy work - related injury insurance benefits, including medical expenses, disability allowances, etc.

5. Maternity insurance: The employer pays for maternity insurance, and the contribution rate is 0.9%. The employer's monthly contribution is ​
   ×0.9%=59.4
   yuan. Female employees can enjoy maternity leave pay, reimbursement of maternity medical expenses, etc.

In general, the social security benefits you can receive are related to many factors such as contribution years, contribution base, and local policies. The above calculations are only for reference, and it is recommended to consult the local social security department for accurate information.
