Texas Child Support Calculator
Planning estimate for Texas child support using a generic gross-income heuristic. Does not implement the state guideline or determine a court order.
Estimate only — these are not official figures
This planning tool does not implement the state guideline. It applies the same generic gross-income heuristic in every state: 17% of combined entered income for one child, plus 5 percentage points per additional child through five; adds the entered child-care and children’s health-insurance amounts; and allocates that modeled total by each parent’s gross-income share. Overnights only identify the scenario’s modeled payer (the parent with fewer overnights); there is no invented linear custody adjustment. It does not calculate taxes or net/disposable income, state schedules, income definitions or caps, self-support reserves, other-child credits, who paid an added expense, shared/split-custody formulas, deviations, or a legally determined obligor. The Percentage of Income label is sourced framework context, not a claim that the framework is encoded.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the Texas Family Code Chapter 154: https://statutes.capitol.texas.gov/Docs/FA/htm/FA.154.htm.

How This Calculator Works
Calculation methodology and assumptions
This planning tool does not implement the state guideline. It applies the same generic gross-income heuristic in every state: 17% of combined entered income for one child, plus 5 percentage points per additional child through five; adds the entered child-care and children’s health-insurance amounts; and allocates that modeled total by each parent’s gross-income share. Overnights only identify the scenario’s modeled payer (the parent with fewer overnights); there is no invented linear custody adjustment. It does not calculate taxes or net/disposable income, state schedules, income definitions or caps, self-support reserves, other-child credits, who paid an added expense, shared/split-custody formulas, deviations, or a legally determined obligor. Every numeric support output is therefore modeled or derived; none is an official guideline amount.
Key State Information
Texas's guideline is classified as Percentage of Income. That classification is context only and does not change this site's generic formula. Texas applies percentages to the obligor’s monthly net resources, subject to statutory definitions, a periodically adjusted cap, and separate rules for children in more than one household. The familiar 20%–40% schedule is not a gross-income rule and is not shared by every percentage-of-income state. The prefilled Parent 1 income is the statewide median household-income figure, not either parent's presumed income.

Our editorial standardsFrequently Asked Questions
How is child support calculated in Texas?
Texas's official framework is classified as Percentage of Income, but this tool does not reproduce it. This planning tool does not implement the state guideline. It applies the same generic gross-income heuristic in every state: 17% of combined entered income for one child, plus 5 percentage points per additional child through five; adds the entered child-care and children’s health-insurance amounts; and allocates that modeled total by each parent’s gross-income share. Overnights only identify the scenario’s modeled payer (the parent with fewer overnights); there is no invented linear custody adjustment. For a guideline calculation, use Texas Family Code Chapter 154 at https://statutes.capitol.texas.gov/Docs/FA/htm/FA.154.htm. Model classifications were cross-checked against https://www.ncsl.org/human-services/child-support-guideline-models.
How long does child support last in Texas?
This calculator does not determine the duration of support. Duration can depend on state law, the child's age and status, the order, and case-specific facts; check the linked official Texas source.
Can child support be modified in Texas?
This calculator cannot determine modification eligibility or a required change threshold. Use the linked official Texas resource or qualified legal help for the current state rules and filing process.
