Calculation Models
Income Shares Model (Most States)
Calculates the total support obligation based on combined income, then divides it proportionally based on each parent's share of combined income. Includes adjustments for custody time, health insurance, childcare, and other expenses.
Percentage of Income Model (TX, WI)
Calculates support as a percentage of the paying parent's income. Texas uses 20% for 1 child, 25% for 2 children, 30% for 3, etc. Wisconsin uses similar percentages.
