Texas sets child support with a simple formula: a percentage of the paying parent’s monthly net resources, based on how many children the case covers. Judges can go above or below it, but most orders start here.

Net resources: income from all sources, minus federal income tax, Social Security and Medicare, union dues, and the cost of the children's health insurance.
The guideline amount only. It doesn't include medical and dental support, the adjustment for children the parent supports in another household, or reasons a judge can go above or below the guideline. For an official estimate use the Texas Attorney General's calculator. Not legal advice.
The guideline percentages
| Children | Standard | Net resources under $1,000/month |
|---|---|---|
| 1 | 20% | 15% |
| 2 | 25% | 20% |
| 3 | 30% | 25% |
| 4 | 35% | 30% |
| 5 | 40% | 35% |
| 6 or more | Not less than the 5-child amount | Not less than the 5-child amount |
The cap
The percentages apply to the first $11,700 a month of net resources, the amount the Attorney General set effective September 1, 2025. It’s adjusted for inflation every six years. Above the cap, a judge can add support based on what the children actually need.
