In Jiangsu Lianyungang, a social security base of 9100 falls within the middle - upper range among the specified base levels. Here's an in - depth look:

1. Context within the overall range: As of 2024, the upper limit of the social security contribution base in Lianyungang is 24396 yuan, and the lower limit is 4879 yuan. A base of 9100 yuan is far above the lower limit but well below the upper limit, indicating that it represents a medium - to - high - income level in terms of social security contributions.

2. Implications for contribution amounts:

• For employees:

• Pension insurance: If the base is 9100 yuan, the individual's contribution is usually 8% of the base. So, the monthly pension insurance contribution for the individual is ​
  ×8%=
  yuan. The employer's contribution, typically around 16%, is ​
  ×16%=
  yuan.

• Medical insurance: Generally, the individual pays about 2% of the base. So, the individual's monthly medical insurance contribution is ​
  ×2%=
  yuan, and the employer pays a larger proportion, around 6 - 8% (let's assume 7% here), which is ​
  ×7%=
  yuan.

• Unemployment insurance: The individual's contribution rate is usually around 0.5 - 1% (taking 0.5% as an example), so the individual's monthly contribution is ​
  ×0.5%=45.5
  yuan, and the employer also contributes a certain amount, such as 0.5 - 1.5% (assuming 1% here), which is ​
  ×1%=
  yuan.

• Work - related injury insurance and maternity insurance: These are usually paid entirely by the employer. The contribution rate of work - related injury insurance varies by industry, generally between 0.2 - 1.9%, and maternity insurance is around 0.5 - 1% (assuming 0.8% for maternity insurance here), so the employer's work - related injury insurance contribution (for an industry with a 0.5% rate) is ​
  ×0.5%=45.5
  yuan, and the maternity insurance contribution is ​
  ×0.8%=72.8
  yuan.

• For flexible - employed individuals: They bear both the individual and employer - equivalent contributions. If they choose a base of 9100 yuan, they need to pay all the above - mentioned contributions that both employees and employers are responsible for, which means a relatively high financial burden.

3. Impact on future benefits:

• Pension: A higher contribution base like 9100 yuan means that more money is accumulated in the pension account during the working years. When calculating the pension amount, the base pension part and the individual account pension part will be affected. The base pension formula involves factors such as the average salary of local employees in the same period and the average contribution index. A higher contribution base will increase the average contribution index, thereby increasing the base pension amount. The individual account pension is directly related to the amount accumulated in the individual account. With a higher contribution base, more money is deposited into the individual account, and the individual account pension will also be higher.

• Medical insurance: A higher contribution base may not directly translate into higher medical reimbursement ratios, but in some cases, it may affect the upper limit of medical reimbursement or the amount of personal medical account funds. For example, more funds may be allocated to the personal medical account, which can be used for medical expenses such as seeing a doctor and buying medicine.

In summary, a social security base of 9100 yuan in Lianyungang reflects a certain income level of the contributor. It leads to specific contribution amounts for various insurances and has a positive impact on future pension and medical insurance benefits. When choosing a contribution base, individuals should comprehensively consider their current economic situation and future benefit expectations.
