Child Support Guidelines
Every state computes child support from a published guideline formula — income shares, percentage of income, or Melson. These calculators run your state’s own math step by step and link the official worksheet or calculator it comes from. Courts retain discretion to deviate.
Child support guideline model by state
Which of the four published guideline models each verified state computes support with.
- Income shares — both incomes, split proportionally
- Percentage of income — the other parent’s income is not used
- Statutory formula (California §4055)
- Not verified yet — not a finding about the state
