How to calculate social security as the payment period?

The deemed payment period refers to the period when employees are deemed to have paid the old-age insurance premium without actually paying it. Because employees don't pay fees, there is no problem in calculating the payment base. When calculating the basic pension, it is calculated according to the payment index of the payment years: the basic pension is equal to (the average monthly salary of employees in the overall planning area plus the average monthly salary of myself) /2 times the payment years (including the deemed payment years and the actual payment years) multiplied by1%;
