Frequently asked questions

How is child support calculated in Texas?+−
Texas guidelines apply a percentage to the obligor’s monthly net resources based on the number of children before the court. The percentage schedule is in Texas Family Code §154.125. This calculator applies those presumptive percentages to the net amount you enter.
What are net resources for Texas child support?+−
Net resources generally include income minus certain taxes and mandatory retirement contributions, as defined in Texas law and explained in Texas OAG materials. Wage earners often use OAG tax charts to convert gross pay to net. You can estimate take-home pay with our Texas take-home pay calculator, then adjust for items OAG allows.
What is the Texas child support cap in 2025 and 2026?+−
For guideline percentages, net resources are applied up to $11,700 per month (cap effective 2025-09-01). Income above the cap may still support additional orders under §154.126, which courts decide case by case.
Is there a 50/50 child support calculator for Texas?+−
Equal possession (often called 50/50) does not automatically eliminate child support. Guideline worksheets can differ when parents share custody. This tool models the standard percentage-on-net-resources formula for the obligor’s monthly net you enter, not a full OAG worksheet or court order.
Is this the official Texas Attorney General child support calculator?+−
No. This is an independent educational estimator. For official tools and case-specific worksheets, use the Texas Office of the Attorney General child support resources.
How do I calculate child support for high income in Texas?+−
Guideline percentages apply to net resources up to the $11,700 cap. Above that, the presumptive guideline amount is based on the capped net only; additional support may be ordered based on the child’s proven needs.
Does Texas child support include medical support or alimony?+−
Medical support, dental insurance, and spousal maintenance can affect total family obligations but are not included in this basic guideline percentage estimate. Consult OAG materials or a family law professional for those items.
