Understanding Child Support Calculations in Texas

Updated: Jan 7

Child support in Texas is calculated using a formula that takes into account the income of both parents, the number of children, and the amount of time each parent spends with the children. The formula is set by state law and is designed to ensure that children receive the financial support they need to meet their basic needs.


In Texas, child support is generally calculated as a percentage of the obligor parent's net resources (gross income minus certain deductions). The percentage varies based on the number of children:

  • For one child, the obligor parent pays 20% of their net resources.

  • For two children, the obligor parent pays 25% of their net resources.

  • For three children, the obligor parent pays 30% of their net resources.

  • For four or more children, the obligor parent pays not less than 40% of their net resources.

It is important to note that these percentages are only guidelines, and the court has the discretion to deviate from them if it determines that the guidelines would not be in the best interests of the children. For example, the court may order the obligor parent to pay an amount that exceeds the guidelines if it is necessary to meet the needs of the children. This may occur in cases where the obligor parent has a high income or the children have special needs.


In addition to the income of the obligor parent, the court may consider other factors when determining child support, including:

  • The needs of the children, including their medical and educational expenses

  • The ability of the obligee parent to meet the needs of the children

  • The standard of living the children
