Child Support Guidelines: United States
In the United States, child support calculations vary by state but generally consider:
- Both parents’ incomes and earning capacities
- Number of children requiring support
- Custody arrangement and parenting time
- Child’s healthcare, education, and special needs
- Standard of living the child would have enjoyed
Most states use an “income shares” model that estimates the amount parents would spend on children if living together.
