Estimated Monthly Child Support
Child support calculations vary significantly by state, but most follow either an Income Shares or Percentage of Income model.
Simplified Percentage Model (used here):
Support = (Paying Parent Income) × (Percentage based on # of children) × (Custody Adjustment)
Typical percentages of gross income:
- 1 child: 17-20%
- 2 children: 25-28%
- 3 children: 29-33%
- 4 children: 31-35%
- 5+ children: 35-40%
Custody adjustment: The more time the non-custodial parent has, the lower the support amount may be.
Important: This is a rough estimate only. Actual amounts depend on your state’s specific formula, both parents’ incomes, healthcare costs, childcare, and other factors. Consult a family law attorney for accurate calculations.
