1. Alimony refers to the living and education expenses borne by parents or other persons who have the obligation to support minors. The legal alimony in our country refers to the living expenses, education expenses, medical expenses and other expenses that should be paid by the party who does not live with the child when these people cannot fully perform or do not perform their alimony obligations, that is, when both parents divorce.
 2. Calculation method: The amount of child support fee, according to the provisions of Article 7 of the Several Specific Opinions of the Supreme People's Court on the People's Court's Handling of Child Support Issues in the Trial of Divorce Cases, if there is a fixed income, the child support fee can generally be paid at the rate of 20% to 30% of its total monthly income. The proportion of those who pay for the upbringing of two or more children may be appropriately increased, but generally shall not exceed 50% of the total monthly income. If there is no fixed income, the amount of childcare fees can be determined according to the total income of the year or the average income of the same industry, with reference to the above proportion. It can be seen that the amount of alimony is generally between 20% and 30% of the total monthly income.
 3. The term of payment of childcare fees: generally until the child is 18 years old. If the parents are over 16 but under 18 years old, take their labor income as the main source of income, and can maintain the general local living standard, they can stop paying childcare fees.
