Formula Description

California uses a complex algebraic formula: CS = K[HN - (H%)(TN)]. It factors in both parents' net disposable income, the amount of time the high earner has primary physical responsibility, and the number of children.

Rates & Multipliers

Multiplier applied to K: 1 child = 1x, 2 = 1.6x, 3 = 2.0x, 4 = 2.3x, 5+ = 2.5x.

Income Caps

No strict cap, but high-income earners can request deviations if the amount exceeds the child's needs.

Disclaimer: This is an informational estimate based on standard guidelines. Actual court calculations may differ based on judicial discretion, specific deductions, and unique family circumstances.

California Guidelines

State-Specific Formula

California uses the Income Shares Model. The guideline amount is calculated by combining both parents' net disposable incomes, determining the percentage of time each parent has custody, and applying the statewide uniform guideline percentages (20% for one child, 25% for two, 30% for three, 35% for four, 40% for five or more).

Important Disclaimer

California courts may deviate from standard guidelines based on factors such as health insurance costs, mandatory union dues, special needs of the child, or significant disparity in parental income.
