Texas Child Support Calculator

Texas uses a percentage-of-income model. The court multiplies the paying parent's monthly net resources by a fixed percentage based on the number of children: 20% (1), 25% (2), 30% (3), 35% (4), 40% (5+). Net resources are capped at $11,700/month, so the most a guideline order applies to is that cap.

Effective September 1, 2025, the cap on monthly net resources rose from $9,200 to $11,700 — the largest increase in Texas history. For one child that raised the maximum guideline amount from $1,840 to $2,340/month. Orders finalized on or after that date use the new cap; older orders keep the $9,200 cap unless modified.

Net resources (Family Code §154.062) start with almost all income — wages, self-employment, rental, interest, dividends, pensions, and more — then subtract federal income tax (single filer, standard deduction), Social Security and Medicare tax, union dues, and the cost of the child's health and dental insurance. Texas has no state income tax. Our gross-income mode applies the Texas OAG 2026 tax assumptions automatically.

Yes. Under §154.125(c), if monthly net resources are below $1,000, reduced percentages apply: 15% (1), 20% (2), 25% (3), 30% (4), 35% (5+). This calculator applies the low-income schedule automatically when net resources fall under $1,000.

This MVP estimates the standard single-household guideline. If the paying parent has children in other households, Texas uses a different (lower) percentage table under §154.129. Equal-possession (50/50) arrangements and offsets are also handled case-by-case by the court. For those situations, use the "net resources" mode as a starting point and consult an attorney.
