How California child support works: the formula is IN the statute
California's guideline is a statutory formula — CS = K[HN − (H%)(TN)] — built on both parents' net disposable incomes, the high earner's share of parenting time, and the statutory K brackets, with fixed multipliers for multiple children. The statute even works its own example. Guideline support is presumptively correct; deviation requires findings.
The honesty note
Courts commonly run certified calculator tools on these same inputs; net disposable income has its own statutory deduction list, and a low-income adjustment presumption exists — the court's own calculation controls.
