How Texas child support is calculated

Generally 20% of net resources for one child, 25% for two, 30% for three, 35% for four, and at least 40% for five or more.

Income after federal income tax, Social Security and Medicare, union dues (if any), and the child's health and dental insurance premiums.

Wages, salary, overtime, bonuses, commissions, self-employment income, rental income, pensions, Social Security disability, and unemployment benefits can all count. Need-based benefits like SSI and TANF are excluded.

Yes. The guideline percentages apply up to a maximum monthly net-resources amount set by law and adjusted periodically. Above the cap, a judge can still order more if the child's proven needs justify it.

Texas uses multiple-family guidelines that reduce the percentage for the children in this case when the parent also supports children elsewhere.

Self-employment income is generally gross business income minus reasonable expenses — and courts scrutinize those expenses closely. For variable or seasonal income, it's common to average several months.

Yes. Even with equal time, a court can order support, especially when one parent earns significantly more. And if a parent is voluntarily unemployed or underemployed, support can be based on earning potential rather than set to zero.

No — any calculator gives only a guideline estimate. The actual order depends on verified income, evidence, and the judge's decision.
