60 and 80 individual social security contributions and 100 difference.

Social security payment is divided into four grades: the lowest grade (40%), the first grade (60%), the second grade (80%) and the third grade (100%). The difference is that low-grade social security contributions are low, and the balance of funds entering personal accounts is also small. When calculating the pension in the future, the average contribution index converted into the formula will be low, resulting in less pension, while the social security with high contribution ratio will receive higher pension than the low-grade social security.
