A Clearer Starting Point for Child Support in Texas.
Use this private calculator to estimate a potential monthly child support amount using the Texas guideline percentages and the $11,700 monthly net-resources cap effective September 1, 2025.
Monthly Child Support Calculator
Enter information for the parent who may pay support. The calculator estimates guideline child support based on the information entered.
A Useful Estimate. Not the Whole Picture.
Texas child support guidelines generally begin with the paying parent’s monthly net resources and apply a percentage based on the number of children involved.
The calculation can change when the parent has a legal duty to support children in another household, monthly net resources are below $1,000, income is difficult to calculate, or other circumstances justify closer review.
Start With Monthly Income
The calculator converts the selected pay frequency into an estimated monthly gross amount.
Subtract the Deductions Entered
The calculator subtracts the tax, insurance, dental, and union amounts you provide to estimate monthly net resources.
Apply the Guideline Percentage
The applicable guideline percentage is applied to estimated net resources, subject to the current statutory guideline cap.
Texas Child Support Guidelines
The standard guideline percentages apply to monthly net resources up to $11,700. When net resources exceed that amount, additional support may be considered in appropriate circumstances based on proven needs of the child.
| Children in this case | Standard guideline | Amount at $11,700 cap |
|---|---|---|
| 1 child | 20% | $2,340 |
| 2 children | 25% | $2,925 |
| 3 children | 30% | $3,510 |
| 4 children | 35% | $4,095 |
| 5 or more children | 40% | $4,680 |
Different percentages apply when monthly net resources are below $1,000. Texas also uses adjusted guideline tables when the paying parent has a legal duty to support children in another household. This calculator applies those percentage tables automatically.
Why the Final Child Support Amount May Be Different
A guideline calculation is an important starting point, but it does not resolve every child support question.
Variable or Complex Income
Bonuses, commissions, overtime, self-employment, investment income, and irregular earnings may require a closer look at how income should be evaluated.
Children in Another Household
Texas uses adjusted percentages when a parent has a legal duty to support children who are not part of the current case.
Net Resources Above the Guideline Cap
The standard guideline percentage is limited to the current $11,700 monthly net-resources cap, although additional support may become relevant in some circumstances.
Facts That May Support a Different Amount
Texas law allows courts to consider additional factors when deciding whether applying the guideline amount would be unjust or inappropriate in a particular case.
Before You Rely on a Child Support Estimate
Will the court order this exact amount?
Not necessarily. The calculator produces a guideline estimate based on the numbers entered. Courts can consider circumstances permitted by Texas law, and the amount ordered or agreed upon may differ.
What are net resources for Texas child support?
Net resources generally begin with income from sources recognized under Texas law and then account for deductions allowed by statute. Less common income, self-employment, or unusual deductions may require additional analysis.
What if my income changes from month to month?
Variable income may require reviewing earnings over a representative period. Bonuses, commissions, overtime, self-employment income, and irregular schedules can make a simple one-month estimate less reliable.
Does this calculator include medical and dental support?
The calculator subtracts the children’s health and dental insurance amounts you enter when estimating net resources. It does not separately calculate every possible medical-support, dental-support, arrears, reimbursement, or retroactive-support issue.
What if I support children from another relationship?
Texas uses multiple-family adjusted guideline percentages when the paying parent has a legal duty to support children in another household. Select the applicable number in the calculator so the appropriate percentage table can be used.
A Calculation Is a Starting Point.
If the number raises questions about income, deductions, children in another household, or how the Texas guidelines may apply to your circumstances, the next step may simply be understanding the situation more clearly.
