3. Unemployment insurance: unit contribution rate of 1%, individual contribution rate of 0.5%.

Monthly contribution amount of each social insurance premium

Monthly contribution amount of each social insurance premium = Σ (employee's monthly contribution base for each type of insurance × unit's contribution ratio for each type of insurance + employee's monthly contribution base for each type of insurance × individual's contribution ratio for each type of insurance)

The amount of money paid for pension insurance is equal to the contribution base multiplied by the contribution ratio. The contribution ratio for unit workers is generally 8% of the contribution base for the workers themselves, although there are cases of 14% in places like Guangdong Province and Zhejiang Province.

The contribution ratio for flexible employees is generally 20% of the contribution base of their choice, but there are also cases of 24% in places like Shanghai.
