This calculator is an informational planning aid, not legal advice. It does not create an attorney-client relationship, does not predict a court order, and does not account for every factor a court may consider. An existing order controls until it is modified. Confirm the current statutory cap and guideline figures with counsel before relying on an estimate.
Calculator questions.
It shows the child's health insurance premium and work-related childcare as separate add-ons, because a court may allocate those costs between the parents or treat them as a reason to deviate from the guideline amount. The base guideline support is calculated from net resources and the number of children.
The calculator applies the additional-child adjustment under Texas Family Code §154.128. The guideline percentage is reduced when the obligor has other children for whom support is owed. The court still reviews the final amount and may adjust it.
Texas applies a monthly cap to the net resources used for guideline support. The figure is adjusted periodically; this tool uses $11,700 per month for 2026. A court can order support above the cap if the evidence supports it, so the cap is not an absolute ceiling.
No. The guideline amount is presumed reasonable, but a court can deviate based on the child's needs, the parents' circumstances, extraordinary expenses, or other factors. Discovery, evidence, and negotiation can change the outcome.
Yes. The calculator runs entirely in your browser. Nothing you enter is saved, transmitted, or sent to NKH Law Firm, and the information disappears when you close or refresh the page.
