The 3 Child Support Models Used by States
Income Shares
Used by 40+ states incl. Ohio, California, FloridaCombines both parents' incomes to estimate the total amount a household would spend on the children, then splits that obligation proportionally.
Percentage of Income
Used by Texas, Wisconsin, and a few othersCalculates support as a flat percentage of the paying parent's income only — the other parent's income isn't part of the formula.
Melson Formula
Used by Delaware, Hawaii, MontanaMost complex — first ensures each parent can meet their own basic needs, then shares remaining income for the children's needs.
Common Questions
Can parents agree to a different amount?
Yes — parents can negotiate a different amount in most states, and a judge will typically approve it as long as it meets the child's needs and both parents agree it's fair.
Does parenting time affect support?
Almost always. More time with the paying parent usually reduces the transfer payment, since that parent is covering more day-to-day costs directly.
What counts as income?
Wages, bonuses, self-employment income, rental income, and most other regular income sources. Some states also impute income for voluntarily unemployed or underemployed parents.
How long does child support last?
Typically until the child turns 18 or graduates high school, whichever is later.
