This is an estimate for information only — not legal advice, and not a court calculation. Judges can and do deviate from guideline amounts. For the number a court would use, see Texas Family Code chapter 154.
This number is a snapshot. Child support depends on parenting time, and parenting time drifts — swapped weekends, changed holidays, summer schedules. Vireo keeps the custody calendar, messages and shared expenses in one timestamped record, so what actually happened is never a matter of memory.

Apply the statutory percentage to the obligor's average monthly net resources: ordinarily 20% for one child, 25% for two, 30% for three, 35% for four, 40% for five, and not less than 40% for six or more, adjusted by the multiple-family table when the obligor has other children. Low-income percentages apply when net resources are below the statutory threshold. Above the cap, add support based on proven needs under section 154.126.
How income is counted: Net resources under Family Code sections 154.061-.070 begin with all statutory resources and subtract Social Security taxes, federal income tax based on the statutory single-person/one-exemption method, state income tax actually paid, union dues, and the child's health and dental insurance costs paid by the obligor. The 2026 OAG tax charts implement the tax conversion for common cases.
