What this site is
Family Support Calc builds single-purpose calculators for family law estimates — starting with child support and alimony, state by state. Each tool is built around one goal: let someone get a fast, private, source-cited estimate of a guideline amount, without wading through a 40-page statute or paying for a consultation just to get a ballpark figure.
We are a small editorial and engineering operation, not a law firm. Nobody on this site's editorial team is holding themselves out as your attorney, and using a calculator here does not create an attorney-client relationship of any kind.
How we source every formula
YMYL content — anything that could affect someone's money, health, or legal standing — carries a higher bar, and we hold our own calculators to it. Every number our tools use comes from a documented process:
Primary source only. We build each formula directly from the official statute, guidelines schedule, or court-approved worksheet for that state — not from third-party summaries. For Florida child support, that's Fla. Stat. § 61.30 and the associated Florida Family Law Rules of Procedure Form 12.902(e).
Cited and dated. Every calculator page links its source statute and states the date it was last verified against that source, directly on the page — not buried in a footer.
Tested against known values. Before publishing, we run each formula against worked examples with known expected results, cross-checked against the statutory table or an official worksheet, and document the test cases.
Reviewed on a schedule, not just once. State guidelines schedules change — Florida's is reviewed by the Legislature at least every four years, and other states update on their own cycles. We track each source and re-verify on a recurring schedule, with the last-checked date visible on every calculator.
What we don't model — and say so
A guideline formula is rarely the whole story. Courts can deviate from the guideline amount, income can be imputed to an unemployed parent, and extraordinary expenses can shift a case above or below the statutory number. Where our calculator doesn't model one of these factors, we say so explicitly in that tool's "Estimation limits" section rather than quietly producing a number that looks more precise than it is.
Privacy by design
Every calculation on this site runs entirely in your browser. We do not transmit, store, or log the income, custody, or personal figures you enter into a calculator — there's no server-side processing to send them to. We use privacy-respecting, cookieless analytics (Umami) to see aggregate traffic like page views, not individual inputs.
Corrections and updates
If you believe a formula, a cited figure, or a source link is out of date or incorrect, we want to know. Send the calculator name, the specific figure in question, and — if you have one — a link to the current official source, to the address below. We review correction reports and update the page's "last verified" date whenever a change is made.
