How Texas Child Support is Calculated
In Texas, child support is calculated using a standard percentage model based on the non-custodial parent's Net Resources. Unlike some states that use an "income shares" model factoring in both parents' incomes, the Texas formula relies almost exclusively on the income of the parent paying support.
Our Texas Child Support Calculator automatically applies the complex percentage matrix found in the Texas Family Code, making it simple to estimate your obligation.
Gross vs. Net Resources
Child support is not based on your gross salary. Instead, it is based on "Net Resources." To find your net resources, you take your total gross income and subtract:
- Federal Income Taxes (based on the tax rate for a single person claiming one exemption).
- Social Security Taxes & Medicare Taxes (FICA).
- Union Dues (if required).
- Health and Dental insurance premiums specifically paid for the child(ren) before the court.
The Percentage Guidelines
Once your Net Resources are calculated, a specific percentage is applied. If you have no other children to support, the standard rates are:
- 1 Child: 20% of Net Resources
- 2 Children: 25% of Net Resources
- 3 Children: 30% of Net Resources
- 4 Children: 35% of Net Resources
- 5+ Children: 40% of Net Resources
If you are legally supporting other children (e.g., from a previous marriage), the state applies a slight reduction to these percentages to ensure fairness. The calculator automatically adjusts for this using the official state matrix.
