California
California calculates statutory child support using a precise algebraic formula: CS = K[HN - (H%)(TN)]. Support is determined by parents’ net disposable incomes, the higher earner’s percentage of physical custody (H%), and statutory multi-child multipliers.
Massachusetts
Massachusetts applies an Income Shares Model that calculates child support based on the combined gross incomes of both parents and the number of children. In shared physical custody (121 to 183 overnights, or 33% to 50%), the court applies a reciprocal offset calculation.
New York
New York calculates child support under the Child Support Standards Act (CSSA). Combined parental income is multiplied by a statutory child percentage (17% to 35%) up to the statutory cap ($183,000/yr), and apportioned between parents based on their pro-rata income shares.
Texas
Texas bases child support exclusively on the paying parent’s (Obligor’s) Net Resources. The custodial parent’s income is not factored into the basic guideline calculation. Net resources are subject to a statutory monthly cap of $9,200.
