## About

Child support rules are public law, but the math behind them is hard to find and easy to get wrong. SupportDecode runs the real state formulas and shows its work — every rate, cap, and table links to an official source with effective and last-checked dates. It is a FREE child-support calculator covering all 50 US states + Washington DC, plus custody-schedule tools, expense-split calculators, and guides for parents, including single parents.
