What this is
About CleanCalc
CleanCalc estimates child support and spousal support, one calculator per state. Support guidelines are set state by state, so each calculator is built on its own state's statute, with the formula and the math shown next to the number.
Why we built it
Many support calculators ask a dozen or more questions, use unexplained jargon, and present a final number with no breakdown of how they got there. Some are lawyer-referral lead funnels disguised as calculators.
We thought the floor for a tool that handles a number this important (monthly support is often the largest line item in either parent's budget) should be: show the formula, with the user's actual inputs substituted, in plain English. If our number doesn't match a court order or an attorney's calculation, you should be able to see exactly why. That's what this tool does.
States we cover
- California: Child + Spousal Support (how it works and FAQ)
- Texas: Child + Spousal Maintenance (how it works and FAQ)
- Florida: Child + Spousal Support (how it works and FAQ)
Planned: New York, Pennsylvania, Illinois, Ohio, Georgia, North Carolina, Michigan. We add states one at a time. Each new state gets its own engine, built from that state's statute and checked against that state's official calculator, rather than one formula approximating fifty.
Why you can verify the math
Every result shows the statute's formula with your numbers substituted, and cites the section each step comes from, so you can check any step against the official text yourself. Each state's engine is tested against that state's official calculator on a fixed set of cases, and the whole system runs more than 1,500 automated tests on every change. Where a statute publishes its own worked example, that example is one of our test cases. Each state's how-it-works page says how that state is checked.
What it doesn't do
- It is not legal advice, and it does not create an attorney–client relationship. See Terms.
- It does not fill out court forms or file anything for you. What the $29 PDF contains, and how courts treat it, differs by state.
- It estimates the guideline figure. A court can order a different amount based on the facts of your case.
Who built it
An independent project. Not affiliated with any law firm, court, or state child support agency. The engine source code lives in a private repository. The calculators are also available in Spanish.
