Estimate support with a state calculator built on the official guideline, or find the official tools for your state.

State calculators

Each calculator follows that state’s current official guideline and worksheet, and is checked against the state’s published schedule and any worked examples the state publishes. It gives an itemized estimate; the court’s worksheet controls.

Official tools for every state

Support calculations require more than two incomes and a child count. Parenting arrangements, the state’s definition of income, deductions, other obligations and additional expenses can affect the result. LawCat adds a state calculator only after it matches that state’s published schedule cell by cell and follows its official worksheet. Some states publish no worked examples; where a state’s printed example disagrees with its own worksheet arithmetic, the calculator follows the worksheet. For other states, use the official tools below.
