About This Launch
SupportDecode is a free child-support calculator covering all 50 US states and Washington DC. It estimates support using each state's formula and shows its work: every rate, cap, and table links to an official source with effective and last-checked dates. It also includes custody-schedule tools, expense-split calculators, and guides for parents. Results are estimates only and not legal advice.
Why I Built This
Child support rules are public law, but the math behind them is hard to find and easy to get wrong. I built SupportDecode so parents can see how their state's formula works, with every number linked to an official source.
