Texas Child Support Calculator
Estimate your monthly child support obligation under Tex. Fam. Code § 154.125. Enter your numbers below for an instant estimate with a step-by-step breakdown and statute citations.
What You'll Need
Gather these four figures first for an accurate Texas estimate:
- Each parent's gross monthly income — recent pay stubs and last year's tax return are the best source.
- Number of children covered by the order.
- Parenting time — roughly how many overnights per year the child spends with each parent.
- Monthly health insurance and childcare costs for the children.
Texas Child Support Calculator
This state uses the Percentage of Income model, which calculates support based solely on the obligor's (paying parent's) net income.
Based on Tex. Fam. Code § 154.125 · Effective September 1, 2025
Enter income details to see your estimate
Your estimate updates as you type, using the guideline formula named above. Fields marked with an asterisk are required.
Once a figure appears, open the step-by-step breakdown to see each stage of the math, or try the what-if scenario to see how a different income or number of children would change the result.
The result is a guideline estimate, not a court order. A judge can set a different amount based on the facts of a case.
How Texas Calculates Child Support
Texas determines child support using the Percentage of Income Model, the standard set out in Tex. Fam. Code § 154.125. Under this model, support is based primarily on the paying parent's income: a set percentage (which usually rises with the number of children) is applied to that parent's income to produce the obligation.
The calculator above applies that formula to the income and expense figures you enter and shows each step of the math, so you can see exactly how the estimate is built. Because every order ultimately runs through a judge, the guideline figure is a starting point rather than a guaranteed result — the sections below explain what goes into it and where real orders can differ.
Key Rules Behind the Texas Formula
- Texas uses the Percentage of Income model, basing support solely on the obligor's net resources.
- The net resource cap was increased from $9,200 to $11,700/month effective September 1, 2025. The cap is set administratively by the Title IV-D agency (Texas HHS) and published in the Texas Register under Tex. Fam. Code § 154.125(a-1).
- Net resources include all wage and salary income, self-employment income, tips, bonuses, commissions, rental income, dividends, interest, and other income sources.
- The court may order support above the guideline amount if the children's proven needs exceed the calculated amount.
What Counts as Income
Child support guidelines are built on each parent's income, so the figure you enter matters more than any other input. Most states start from a broad definition of gross income that includes wages, salary, tips, commissions, bonuses, self-employment earnings, and many forms of government benefits, then subtract specific deductions to reach the income the formula actually uses.
Texas's rules under Tex. Fam. Code § 154.125 spell out which deductions apply and whether the formula runs on gross or net income. The calculator's field labels tell you which figure to enter; when in doubt, use your most recent pay stubs and tax return, and confirm the details in the Texas child support laws guide.
How to Establish a Child Support Order in Texas
A child support obligation becomes enforceable only once a court or the state child support agency issues an order. Either parent can request one, and in Texas, as in every state, the local child support agency that operates under the federal Title IV-D program can open a case, locate the other parent, establish paternity if needed, and ask the court to set support using the guideline formula.
When you apply, expect to provide proof of income for both parents, the child's information, and details about health insurance and childcare costs — the same inputs this calculator uses. Running your numbers here first gives you a realistic idea of the order amount before you file.
What Is the Average Child Support Payment in Texas?

Texas does not publish an official “average” child support payment. This estimate was calculated using the Texas guideline formula above with median income data from the U.S. Census Bureau, American Community Survey (ACS) 2024 — Texas Median Earnings. Your actual amount will differ — use the calculator above with your own numbers for a personalized estimate.
Assumptions used in this estimate
- •Obligor gross income of $4,585/month (Texas median full-time earnings, U.S. Census ACS 2024)

- •$250/month for children's health insurance
- •No union dues or other mandatory deductions
- •Standard federal tax and FICA deductions estimated

Important Legal Disclaimer
This calculator provides an estimate only based on Texas's child support guidelines. Actual court-ordered amounts may differ based on factors not captured here, including special needs, shared custody arrangements, travel costs, and judicial discretion.
This is not legal advice. Consult a family law attorney for guidance specific to your situation.
How to Modify a Texas Child Support Order
Child support orders are not permanent. Texas courts can revisit an order when there has been a substantial change in circumstances — for example, a significant change in either parent's income, a change in custody or parenting time, or a meaningful change in the child's needs. Federal rules also entitle parents in IV-D cases to request a review periodically (often about every three years) even without a major change.
To estimate a new amount, re-run the calculator with the updated figures. If the guideline result is meaningfully different from your current order, that gap is often what supports a modification request — though only a court can actually change the order.
How Child Support Is Enforced in Texas
Once an order is in place, Texas has strong tools to collect it. The most common is income withholding: federal law requires most new orders to be paid through automatic wage garnishment, so payments are deducted from the paying parent's paycheck. When payments fall behind, enforcement can escalate to intercepting tax refunds, suspending driver's or professional licenses, placing liens on property, reporting the debt to credit bureaus, and, in serious cases, contempt-of-court proceedings.
Interest and penalties can accrue on unpaid support, so an order that goes unaddressed tends to grow rather than disappear. If your circumstances have changed, seeking a modification through the court is almost always better than simply paying less than the order requires.
Frequently Asked Questions
Is this Texas child support calculator accurate?
It applies the official Texas guideline formula from Tex. Fam. Code § 154.125 to the numbers you enter, so it gives a close estimate of a typical guideline order. It is not an official court calculation — a judge can order a different amount based on the specific facts of your case.
Can a judge order a different amount than the calculator shows?
Yes. The guideline figure is a presumptive starting point, but Texas courts can deviate up or down when the standard amount would be unfair — for example, because of extraordinary medical or educational expenses, a child's special needs, or other obligations. The order the judge signs controls.
What income do I enter into the Texas calculator?
Use the figures described by each field's label — generally your regular income from work and other sources. Texas's guidelines define exactly which income counts and which deductions apply, so your most recent pay stubs and tax return are the best source for accurate numbers.
Is child support taxable in Texas?
No. Under federal tax law, child support is not taxable income for the parent who receives it and is not tax-deductible for the parent who pays it. This is different from spousal support and does not change from state to state.
How long does child support last in Texas?
In most cases child support continues until the child reaches the age of majority or finishes high school, but orders can extend longer — for instance, for a child with a disability. Check the Texas child support laws guide for the specific rules that apply to your situation.
Disclaimer
This calculator provides estimates only and is not a substitute for legal advice. The actual amount ordered by a Texas court may differ based on factors including but not limited to: the special needs of the child, travel expenses for visitation, extraordinary educational or medical expenses, the parents' other support obligations, and the court's discretion to deviate from the guidelines. For advice about your specific situation, consult a licensed Texas family law attorney.
