Texas Child Support Calculator
Estimate guideline child support both ways — income to support, or a support amount back to the income behind it. Instant, no sign-up.
Child Support Estimator
Works both ways: enter income to estimate support, or enter a support amount to see the income behind it. Figures are for the paying parent.
Estimate only. The gross-to-net conversion uses standardized 2026 tax figures (the Texas Attorney General’s official Tax Charts are authoritative). A court can order a different amount. See how the math works →

Frequently asked questions
How much is child support in Texas for one child?
Texas guideline child support for one child is 20% of the paying parent’s monthly net resources, up to the $11,700 cap — a maximum of about $2,340 per month. The percentage rises to 25% for two children, 30% for three, 35% for four and 40% for five.
Is Texas child support based on gross or net income?
Net. The guideline percentage is applied to net resources — gross income minus Social Security and Medicare taxes, federal income tax figured for a single filer, union dues, and the cost of the child’s health and dental insurance.
What is the $11,700 cap?
Effective September 1, 2025, guideline percentages apply only to the first $11,700 of monthly net resources (up from $9,200). A court can order more above the cap only if the requesting parent proves the child’s needs exceed it.
Does this calculator give an exact amount?
No. It produces a guideline estimate. Courts can deviate for 50/50 possession, other children, travel costs, medical expenses and many other factors. For an exact calculation, speak with a Texas family-law attorney.
