How Child Support Guidelines Work
Child support calculations vary significantly across the United States. States primarily use two legal models: the Income Shares Model, which estimates the amount parents would have spent on their children if living together, and the Percentage of Income Model, which applies a fixed percentage of the non-custodial parent's income based on the number of children.
Additional factors like parenting time, healthcare costs, and childcare expenses further influence the final obligation. The Family Ledger is specifically engineered to navigate these complex, state-specific guidelines and provide accurate estimates tailored to your situation.
