California Child Support Calculator (Estimator)
Guideline-style estimator using net monthly incomes and timeshare. Includes optional “add-ons” (childcare/health premiums) prorated by income share.
Output: Monthly
Inputs
Enter the % of time the higher-earning parent has the child(ren). Example: 20 means the higher earner has 20% custody time.
Optional Add-ons (Prorated by Income Share)
This calculator estimates the guideline structure (CS = K[HN − (H%)(TN)]). Actual court numbers can change materially due to tax impacts, allowable deductions, hardship factors, and certified guideline rules.
Disclaimer: Estimate only. Not legal advice. For court filings, use a certified calculator and/or consult a qualified professional.

Tip: If your “net monthly income” numbers are guesses, your output will be off. Use paystubs/tax returns to estimate net disposable income.
