The difference between social security contribution 15 and 20 years is as follows.

1. Basic pensions are different: after reaching the statutory retirement age and the prescribed payment period of old-age insurance, when handling retirement, the pension calculation and payment methods are divided into two parts: basic pension and personal account pension. From the perspective of basic pension, it is determined by three factors: my average social salary in the previous year, my indexed average payment salary and payment period. Compared with those who have paid for 20 years and 15 years, even if they retire that year, the payment period is five years longer. The income coefficient is multiplied by 65,438+0% per year, and those who pay more than five years will have five years of indexed average payment salary, and five years will be 65,438+0%. In other words, the basic salary of people who have paid for 20 years is higher than that of people who have paid for 15 years.

2. Difference of personal account pension: Personal account pension refers to the part that is included in personal account according to the proportion of 8% when we pay endowment insurance. For those who have paid for 20 years, under the same payment base and payment index, personal account has increased by 8% in 5 years. If you retire at the age of 60, the funds and interest in the personal account that has paid for 20 years will be higher. Similarly, if you divide it by 139 months, the pension in the personal account that has paid for 20 years will be higher.

3. Differences in medical insurance treatment: At present, employees pay medical insurance for 25 to 30 years for men and 20 to 25 years for women. After retirement, I will no longer pay medical insurance and enjoy medical insurance benefits for life. Men who have paid 15 years need to pay 10 to 15 years before they can enjoy the retirement benefits of medical insurance. For those who have paid for 20 years, men only need to pay 5 to 10 years. In some places, women have reached the prescribed payment period. Even where they have paid for 25 years, they only need to pay for 5 years to enjoy the retirement benefits of medical insurance.
