The amount of pension you can get when you retire after paying social security for 20 years should be calculated according to the average monthly salary at the time of employment. The specific amount is calculated as follows:

1, because the basic pension consists of basic pension, personal account pension, transitional pension and comprehensive subsidy;

Basic pension = average monthly salary of employees in the previous year ×20%.

2. The calculation method of personal account pension is: the total amount of personal account storage at retirement ÷ 120, and the personal account pension is counted as 1 1% of the payment salary;

3. Transitional pension = average monthly salary of employees in last year × average payment index of employees × previous length of service × 1.3%.

The average monthly salary of employees in the last year when they retire, the total amount of personal accounts when they retire, and their average contribution index cannot be determined until the year of retirement, so it is impossible to calculate how much pension they can get when they retire;

What is certain is that the higher the payment grade, the longer the payment period and the higher the pension after retirement.
