A more thorough explanation:

Child-support guidelines are laws that determine how much money a parent who is required to pay child support must pay. These guidelines are established by each state and are based on the income of the parent who is paying child support and the needs of the child.

Child-support guidelines were created in response to the Temporary Assistance to Needy Families program, which provides financial assistance to families in need. The guidelines ensure that children receive the financial support they need from their parents.

For example, if a parent has a monthly income of $3,000 and is required to pay child support for one child, the child-support guidelines may require them to pay 25% of their income, or $750 per month. This money is intended to cover the child's basic needs, such as food, clothing, and shelter.

Another example is if a parent has two children and earns $4,000 per month, the child-support guidelines may require them to pay 30% of their income, or $1,200 per month, to support both children.

These examples illustrate how child-support guidelines work to ensure that children receive the financial support they need from their parents. The guidelines take into account the income of the parent who is paying child support and the needs of the child, and provide a fair and consistent way to determine the amount of child support that must be paid.
