About Child Support Numbers

Child Support Numbers turns each state's child support guideline into a calculator you can use in a few minutes. Every state writes its own rules: some take a percentage of one parent's income, others combine both incomes and split a table amount, and a few use a formula written into the statute. We apply the rules of the state you pick, show every step, and print the date of the schedule behind the number.

What you get

• A calculator for each state we cover, built from that state's statute or court rule and its current table.
• The steps behind the result: the income used, the base amount, the parenting-time adjustment and any add-ons.
• Guides on the questions that change the number: shared custody, imputed income, changing an order and unpaid support.
• Alimony calculators only where a state has an official formula. Where the judge decides, we explain the factors the law lists and do not guess an amount.

What we are not

We are not a law firm, a court or a government agency, and we are not affiliated with any of them. Nothing on this site is legal advice for your case. We do not refer you to lawyers and nobody pays us to send you anywhere. The calculators are free and need no sign-up; what you type is used only to compute the result on that page.

A court can depart from the guideline, and many details of a real case (how income is proven, what counts as an overnight, existing orders) can change the amount. Treat our numbers as a starting point for a conversation with the other parent, a mediator, the state child support agency or an attorney.
