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.

Frequently Asked Questions

How accurate is this estimated child support calculator? +

This calculator provides estimates based on common formulas used worldwide. Accuracy varies by jurisdiction, as each country and sometimes regions within countries have specific guidelines. For precise calculations, consult local family law resources or legal professionals.

Why does the model year matter in child support calculations? +

Child support guidelines are periodically updated to reflect inflation, changes in cost of living, and updated research on child-rearing costs. The model year allows you to apply guidelines from specific years, which is useful for understanding historical calculations or anticipating future changes.

What factors affect child support amounts most significantly? +

The primary factors are parental incomes (both custodial and non-custodial), number of children, and custody arrangement. Secondary but important factors include healthcare costs, childcare expenses, educational needs, and any special requirements for the child.

How do child support calculations differ between countries? +

Countries use different models: the US typically uses income shares or percentage of income models; the UK uses a formula based on non-resident parent’s income, number of children, and shared care; Australia considers both parents’ incomes and time spent with children; Germany calculates based on both parents’ income and the “Düsseldorf Table.”

Can child support orders be modified? +

Yes, child support orders can typically be modified when there’s a significant change in circumstances, such as income changes (increase or decrease), changes in custody arrangements, or changes in the child’s needs. The process varies by jurisdiction but usually requires court approval.
