Free child support calculators for your website

Put one of our state calculators on your site, blog or organization's page. Copy the code, paste it into your page, done. No sign-up, no fee and no ads inside the widget.

Pick a calculator

Copy the code

Paste it where the calculator should appear. In WordPress, use a Custom HTML block. In Squarespace or Wix, use an Embed or Code block.

The small script lets the calculator grow and shrink to fit. If your site strips scripts, the calculator still works: the frame keeps the fixed height in the code, and on phones, where the calculator is taller, it scrolls inside the frame.

Terms, in short

  • Free for any website, including commercial ones.
  • Keep the credit link under the calculator.
  • We update each state's rules inside the widget ourselves, so your copy stays current with no work on your side.
  • Results are estimates and explanations only, not legal advice. The court or the state agency sets the actual amount. The site is not affiliated with any state agency or court. The full terms of use apply.

What the calculators do

Each one follows its own state's guideline law and official schedule, step by step. How we calculate lists the rules and their sources. What someone types stays in their browser.
