Child Support Calculator: Texas Guideline Component (2026)

Calculate the Texas presumptive percentage component of child support using statutory monthly net resources. This 2026 tool covers one to five children in one support action and assumes no legal duty to support other children. It does not estimate a complete court order or apply another state’s law.

How to use this tool

1. Establish monthly net resources under Texas rules, using the OAG tax charts and permitted adjustments.
2. Enter that resource amount rather than gross wages or an assumed take-home figure.
3. Choose the number of children in this action and confirm there are no other supported children.
4. Read the guideline component and any resources above the percentage cap.

Formula

Monthly component = min(net resources, $11,700) × applicable percentage

Ordinary percentages for 1–5 children: 20%, 25%, 30%, 35%, 40%

Below $1,000 net resources: 15%, 20%, 25%, 30%, 35%

The $11,700 cap took effect September 1, 2025 and appears in the official 2026 charts. Exactly $1,000 uses the ordinary schedule. The result rounds to cents for budgeting. Above-cap resources can support additional court-ordered amounts based on the statutory factors; the displayed cap is not a maximum possible order.

Example

For $4,000 monthly net resources and one child, the ordinary 20% rate gives $800 monthly. For $900 net resources and two children, the low-income 20% rate gives $180. For five children and $20,000 resources, the percentage component is 40% × $11,700 = $4,680, before any additional ordered support.
