How the number of children changes the amount in California

For one child, the guideline amount ranges from $116 a month when Parent A earns $20,000 to $2,444 a month at $250,000, with Parent B earning $40,000.

California uses one statewide formula: CS = K[HN − (H%)(TN)]. HN is the higher earner's net income, TN is both parents' net income and H% is the higher earner's share of parenting time. K is a share of combined income that depends on TN and the timeshare. More children multiply the one-child amount.
