How Texas calculates child support
Texas's child support guidelines are established by Tex. Fam. Code §§ 154.125–.129. Texas uses the percentage of income model, which applies a guideline percentage to the paying parent’s income, scaled by the number of children.
This calculator applies the current guideline edition: § 154.125 percentages; net-resources cap $11,700 eff. 9/1/2025.
The result is the presumptive guideline amount, the starting point a Texas court uses before considering deviation factors. The full line-by-line worksheet, guideline edition, and statutory citation are available in Aequis with a 14-day free trial (credit card required).
Texas child support FAQ
How is child support calculated in Texas?
Texas sets child support under its official guidelines (Tex. Fam. Code §§ 154.125–.129), which follow the percentage of income model. The guideline produces a presumptive monthly amount from the parents' incomes, the number of children, and inputs such as parenting time, childcare, and health insurance costs.
Is this the exact amount a Texas court will order?
No. This is an informational estimate of the presumptive guideline amount. Courts can deviate based on statutory factors, and official worksheets may require inputs this calculator does not collect. Always verify against the official guidelines worksheet before relying on any number.
What income counts for child support in Texas?
Guidelines generally start from each parent's gross income from most sources, with their own definitions, exclusions, and deductions. This calculator uses gross monthly income; consult Tex. Fam. Code §§ 154.125–.129 for what Texas includes.
Do overnights affect child support in Texas?
Many jurisdictions adjust the obligation for parenting time once overnights pass a threshold, and this calculator applies Texas's guideline treatment of overnights where the guideline provides one. The exact effect depends on Texas's formula and the parents' incomes.
