How Texas child support is calculated

Texas uses guideline child support (Texas Family Code, chapter 154). The court starts from the paying parent's monthly net resources: wages, self-employment income and most other income, minus Social Security, Medicare and federal income tax (calculated as a single filer), union dues, and what that parent pays for the children's health and dental insurance.

A percentage of net resources is then applied, based on the number of children:

Children in the casePercentage of net resources
120%
225%
330%
435%
540%
6 or moreNot less than 40%
  • Other children: when the paying parent also supports children outside the case, the percentages are lower. This calculator uses the multiple-family tables.
  • Low income: when net resources are below $1,000 a month, a lower set of percentages applies.
  • Cap: the percentages apply to net resources up to the guideline cap, currently $11,700 a month. Above that, a court can order more based on the children's proven needs.
  • Medical and dental support: courts also order health and dental coverage for the children. Those amounts are separate from the guideline amount shown here.
  • A court can vary from the guidelines when applying them would be unjust or inappropriate.

Estimate only, not legal advice. A court can order a different amount based on the evidence, other deductions, medical and dental support, and its findings.
