How Is Child Support Calculated in Texas?

Published on
August 6, 2026

When parents separate or divorce, one of the first questions they often ask is, "How is child support calculated?" While many people know Texas uses percentage guidelines, the calculation is more nuanced than simply taking a percentage of a parent's paycheck.

Texas child support laws are designed to ensure children receive financial support from both parents while accounting for each family's unique circumstances. Understanding how child support is calculated can help parents set realistic expectations and make informed decisions during a divorce or child custody case.

Key Takeaways

  • Texas child support is generally based on the paying parent's net monthly resources.
  • The percentage used to calculate support typically increases with the number of children.
  • Courts may order an amount that differs from the standard guidelines when circumstances justify it.
  • Medical and dental support are typically addressed in addition to child support.
  • Child support orders may be modified if there has been a material and substantial change in circumstances.

Understanding Child Support in Texas

Child support is a court-ordered payment intended to help cover the costs of raising a child. In Texas, one parent typically pays child support to the other parent to help provide for the child's daily needs, including housing, food, clothing, education, and other necessary expenses.

Although child support is often established during a divorce, it may also be ordered in cases involving unmarried parents or other child custody proceedings. If you're beginning the divorce process, understanding what to expect in a contested Texas divorce can help you prepare for issues such as custody, property division, and child support.

How Child Support Is Calculated

In most cases, Texas child support is calculated using the paying parent's net monthly resources and the child support guidelines established under Texas law.

Rather than looking only at gross income, the court begins by determining the paying parent's net resources. Once that amount has been calculated, the court generally applies a percentage based on the number of children before the court.

Texas Child Support Guidelines

Number of Children Guideline Percentage*
1 child 20%
2 children 25%
3 children 30%
4 children 35%
5 children 40%
6 or more children At least 40%

*These are the standard guideline percentages. Texas courts may order a different amount depending on the facts of the case.

While these percentages provide a starting point, every family is different. Courts have discretion to deviate from the guidelines when appropriate.

What Are Net Monthly Resources?

One of the most important parts of calculating child support is determining the paying parent's net monthly resources.

Depending on the circumstances, net resources may include income from several sources.

Examples of Net Monthly Resources

May Be Included Examples
Employment income Wages, salary, commissions, bonuses
Self-employment income Business earnings and certain self-employment income
Retirement income Certain retirement or pension benefits
Other income Rental income, unemployment benefits, and other qualifying income

Texas law also permits certain deductions when calculating net resources. Because every financial situation is different, determining the correct amount may require a careful review of income and applicable deductions.

When Can Courts Depart from the Guidelines?

Although the child support guidelines apply in many cases, they are not absolute. Texas courts may order a different amount if applying the standard guidelines would not be in the child's best interests.

For example, a court may consider:

  • The child's medical, educational, or special needs.
  • Extraordinary expenses related to the child's care.
  • The financial resources of both parents.
  • The amount of time each parent spends caring for the child.
  • Other factors permitted under Texas child support laws.

The court's goal is to reach a child support order that fairly reflects the family's circumstances while meeting the child's needs.

Because child support is intended to support the child's best interests, judges often consider many of the same circumstances they evaluate when determining child custody in Texas.

Factors That May Affect Child Support

Factor Possible Effect
Number of children Changes the guideline percentage used to calculate support.
Net monthly resources Primary factor used in determining child support.
Special medical or educational needs May justify a different support amount.
Health insurance costs May affect the overall financial obligation.
Other children the parent supports May influence the calculation in certain circumstances.

Medical Support and Health Insurance

Health insurance and medical support are generally addressed separately from the guideline child support amount.

The court may order one parent to provide health insurance for the child or require the parents to share uninsured medical and dental expenses. These obligations are typically included in the final court order along with child support.

Does 50/50 Custody Eliminate Child Support?

Not necessarily.

Many parents assume that equal parenting time automatically means neither parent will pay child support. That is not always the case.

Even when parents share time equally, the court may still order child support based on each parent's financial circumstances and the child's needs. . Our article explaining whether 50/50 custody is guaranteed in Texas explores why equal parenting time does not always mean equal financial responsibility.

Modifying a Child Support Order

Child support orders are not always permanent.

If there has been a material and substantial change in circumstances, such as a significant change in income or the child's needs, either parent may be able to ask the court to modify the existing order.

Likewise, if the parenting schedule or living arrangements have changed significantly, it may be appropriate to pursue both a child support modification and a child custody modification.

Enforcing an Existing Child Support Order

When a parent fails to comply with a child support order, the court has several enforcement options available.

Depending on the circumstances, enforcement may include wage withholding, contempt proceedings, property liens, or other legal remedies. Our guide to child support enforcement outlines the options.

It's important to remember that unpaid child support does not allow a parent to deny court-ordered visitation. Parents experiencing problems with parenting time should instead explore custody enforcement in Texas.
