Child support is calculated based on several factors, which vary slightly by state laws but generally follow similar principles. Here’s a breakdown of how it works:
Income-Based Formulas
Most states use an income shares model or a percentage of income model to determine child support:
Income Shares Model (used by most states):
Both parents' incomes are combined.
The court estimates the amount that would have been spent on the child if the parents lived together.
This amount is then divided proportionally based on each parent's income.
Example:
If the combined monthly income is $8,000, and the state guideline says $1,200 should be spent on the child, the parent earning 60% of the income pays 60% of the $1,200.
Percentage of Income Model (used by a few states):
Child support is calculated as a percentage of the non-custodial parent's income.
The percentage may vary depending on the number of children.
For example, 17% for one child, 25% for two children, etc.
Factors Considered in Calculation
Income of Both Parents:
Includes wages, bonuses, commissions, self-employment income, and sometimes even gifts or lottery winnings.
Parenting Time (Custody Arrangements):
If the non-custodial parent has substantial overnight stays with the child, support payments may be adjusted.
Child’s Needs:
Medical expenses, education, extracurricular activities, and special needs.
Existing Obligations:
If either parent has other children to support, it may affect the calculation.
Health Insurance and Medical Expenses:
Courts typically require one or both parents to provide health insurance for the child.
Childcare Costs:
Daycare or after-school care expenses are often included in the calculation.
Modifications and Adjustments
Child support orders can be modified if there is a significant change in circumstances, like job loss, increased income, or changes in custody.
Either parent can request a review, typically after a set period (e.g., every three years) or if there’s a major life change.
Enforcement of Child Support
If a parent fails to pay, the court can enforce it through:
Wage garnishment
Property liens
Seizure of tax refunds
Suspension of driver's licenses
Example Calculation (Income Shares Model)
Parent A's income: $4,000/month
Parent B's income: $2,000/month
Combined income: $6,000/month
State guideline: 20% of combined income for one child → $1,200/month
Parent A would pay 66% ($800) and Parent B would pay 33% ($400), proportionate to their earnings.
