About Child Support By State

ChildSupportByState.com exists for one reason: to help US parents understand what child support might look like in their situation before they hire an attorney or sit down in front of a judge. Family law is intimidating, and the cost of asking a basic "how much will I pay?" question can run into hundreds of dollars in attorney fees.

Our calculator uses each state's published guideline framework — Income Shares for most states, Percentage of Income for Texas — and produces a fast, anonymous estimate. We don't collect your data, we don't ask for your email, and we never share inputs with anyone.

What we offer

• A free child support calculator covering all 50 US states
• State-specific calculator pages with example tables and FAQs
• Plain-English guides on modification, taxes, enforcement, and 50/50 custody
• Regular updates as state guidelines change
