How is the amount of child support in Texas calculated?

On Behalf of | Sep 23, 2026 | FAMILY LAW - Paternity

Child support plays an important role in helping children maintain financial stability after their parents separate or divorce. 

Texas courts follow specific guidelines to determine support amounts, but every family’s circumstances can influence the final result.

The paying parent’s net resources are calculated

The starting point is determining the paying parent’s net monthly resources. Courts review income from employment, self-employment, rental properties, pensions, investment earnings and certain government benefits. Deductions are then made for certain expenses, such  

After identifying income sources, allowable deductions are applied, which may include taxes, health insurance costs for the child and other court-ordered expenses. The remaining amount forms the basis for the support calculation.

Applying Texas guideline percentages

Texas uses guideline percentages that are tied to the number of children requiring support. Once net resources are calculated, the court applies the appropriate percentage to determine a baseline obligation. The guidelines are 20% for one child, 25% for two, 30% for three, and so on. If, for example, the non-custodial parent earns $5000 net per month and must pay support for one child, they would pay $1000. That amount could then be adjusted upward if a child has special expenses, such as unusual educational needs, or adjusted down for the parent’s child-related expenses, such as health insurance premiums.

There are also caps on how much support can be awarded, and further adjustments for payors who have income above certain statutory thresholds. These guidelines create consistency while helping ensure that children receive financial support that reflects the parents’ ability to contribute.

If you have questions about support calculations, modifications or enforcement issues, seeking professional legal guidance can help you better understand your rights and obligations under Texas law.
