The amount of child support in Texas depends on the noncustodial parent's net monthly income and the number of children. As of September 1, 2025, Texas updated the child support cap from $9,200 to $11,700 in net monthly income, which means child support calculations now consider income up to this new higher cap. The standard Texas child support guidelines for one household are based on percentages of net monthly income up to $11,700 as follows:

• 1 child: 20% of net income, up to $2,340 per month
• 2 children: 25% of net income, up to $2,925 per month
• 3 children: 30% of net income, up to $3,510 per month
• 4 children: 35% of net income, up to $4,095 per month
• 5 or more children: 40% of net income, up to $4,680 per month

Net monthly income is calculated after allowing deductions such as taxes, union dues, health insurance premiums, and mandatory retirement contributions. The guidelines apply only up to the income cap, but courts may deviate based on the child's proven needs or the parent's ability to pay if income exceeds this cap. Hence, child support obligations in Texas are primarily percentage- based on income with a cap allowing for a maximum guideline amount related to the number of children involved.
