What might support look like?

A simplified estimate using the income-shares model most states use for child support and general spousal-support guidelines. This is a directional number, not a court order - real filings depend on your state's specific formula, custody split, and judicial discretion.

How we got there
This is a starting estimate. State formulas vary - some use income shares (used here as a proxy), some use percentage of obligor, some cap at a shared-parenting threshold. Alimony (spousal maintenance) uses widely different formulas by state. Bring this to a licensed family attorney in your jurisdiction for a real answer.
State rules varyResults are directional only. Every state has its own statutes, case law, and fee structures. This calculator uses general assumptions that may not reflect the specific rules in your state. Confirm with an attorney licensed in your jurisdiction before relying on these numbers.
