What is the difference between social security contribution 15 and 30-year pension?

Under the condition that the monthly payment is unchanged:

1 and 30-year social security contributions are much larger than 15 years.

2. The final personal account deposit will be very different.

3. The biggest difference between social security payment 15 and 30 years is that the longer the social security payment time, the more pensions.

Calculation formula of pension:

Retirement pension = basic pension+personal account pension

Basic pension = (the average monthly salary of employees in the province last year? My indexed average monthly payment salary) ÷2× payment years × 1% = the average monthly salary of employees in the whole province last year (1 my average payment index) ÷2× payment years × 1%.

The difference between social security payment 15 and 30 years: the payment period of social security payment of 30 years is twice that of social security payment 15. Under the same circumstances, the basic pension for 30 years of social security will be much more.

Personal account pension = personal account deposit ÷ calculation months (Note: the calculation months for 50-year-old retirement are 195, and the calculation months for 55-year-old retirement are 170, 139).

To sum up, the difference between social security payment 15 and 30 years is mainly the difference in the total payment, and the monthly pension received after retirement is also different. In general, the pension received in 15 years is much less than that in 30 years.
