How Child Support Is Calculated

Child support calculations in the USA are based on federal guidelines and state-specific modifications. The basic formula is:

Child Support = (Parent's Income × Percentage) ÷ Number of Children

The percentage used depends on the state and custody arrangement. For example, in California:

  • Joint custody: 25% of the parent's income
  • Sole custody: 35% of the parent's income

Each state has its own guidelines, which may include deductions for health insurance, childcare, and other expenses. The calculator uses these state-specific percentages to provide accurate estimates.

Examples of Child Support Calculations

Here are two examples of how the calculator works:

Example 1: Joint Custody in New York

Parent's income: $4,000/month
State: New York
Custody: Joint
Number of children: 2

Calculation: ($4,000 × 20%) ÷ 2 = $400/month

Estimated child support: $400/month

Example 2: Sole Custody in Texas

Parent's income: $5,000/month
State: Texas
Custody: Sole
Number of children: 1

Calculation: ($5,000 × 30%) ÷ 1 = $1,500/month

Estimated child support: $1,500/month

These examples show how the calculator applies state-specific percentages to determine child support amounts.
