**Important Disclaimer:**

This calculator is for educational purposes only and provides only rough estimates that might vary significantly from official state calculations. Official calculations include many additional factors not included here. This tool does not constitute legal advice and should not be relied upon for any important decisions. For accurate calculations, please consult a family law attorney or your state's official child support agency.

How to Use the Child Support Calculator

Start by selecting your state and entering both parents' incomes, parenting time, and health insurance costs. Whenever your state publishes a worksheet or table—such as the Texas guideline worksheet or the California percentage schedule—we mirror those rules so the math reflects real-world outcomes. You will see a range showing the presumptive guideline amount along with common deviations judges approve.

Our calculator never stores the information you enter. You can run scenarios for different custody schedules, income changes, or child care expenses to understand how support might change before you commit to a settlement or court filing.

What Impacts Child Support by State?

  • Income Shares vs. Percentage Models: States such as Illinois and New York use income-shares formulas that consider both parents' earnings, while states like Texas apply a percentage of the noncustodial parent's net income.
  • Parenting Time Adjustments: Many states reduce support when parenting time is close to 50/50 or grant credits for travel expenses.
  • Health Insurance & Child Care: Required health coverage premiums and verified work-related child care costs are usually added to the base award.

Review your state's statutes or administrative code to confirm any special adjustments for extraordinary medical expenses, private school tuition, or other deviations.

Next Steps After Estimating Support

Use the estimate as a planning guide while you negotiate or consult with a family law attorney. Bring printouts of your scenarios so counsel can validate that the inputs match your tax returns and paystubs.

Every state requires financial affidavits and supporting documents. Staying organized will help you avoid delays and reduce legal fees.
