Texas Child Support Calculator

Estimate monthly Texas child support from the paying parent's gross income, number of children, and optional deductions. Texas guidelines apply a percentage to monthly net resources — custody percentages and calendar generation are separate tools.

Planning estimate only. Courts may order a different amount after medical support, other children, parenting arrangements, and case-specific review.

How Texas Child Support Is Calculated

Texas guideline support follows a short sequence. Courts and the Attorney General use more detailed records, but the logic starts the same way.

Step 1: Determine monthly net resources

Start with gross monthly income, then subtract allowable amounts such as Social Security tax, Medicare tax, federal income tax, mandatory union dues, and child health insurance the paying parent provides. The remainder is net resources.

Step 2: Apply Texas guideline percentages

Multiply guideline resources used by the percentage for the number of children before the court. The calculator caps guideline resources at $11,700 in monthly net resources when estimated net resources exceed that amount. If the paying parent supports other children, a lower percentage may apply.

Step 3: Review adjustments and court discretion

The guideline amount is a starting point. Medical support, low-income rules, high-income caps, and court findings can change the final order.

These percentages apply to net resources when no multiple-family adjustment or low-income rule changes the rate. When estimated net resources fall below $1,000 and no other supported children are entered, lower guideline percentages may apply. A judge may order above or below the guideline when the evidence supports it.

Texas guideline percentages — 1 to 5+ children

Applied to obligor net monthly resources — examples use 4,850 net.

Children Percentage Example support
1 child 20% $970 on $4,850 net
2 children 25% $1,213 on $4,850 net
3 children 30% $1,455 on $4,850 net
4 children 35% $1,698 on $4,850 net
5+ children 40% $1,940 on $4,850 net

Multi-family and above-guideline cases use different worksheets

Texas Support Worksheet Fields

Each calculator field maps to a line on a guideline worksheet — enter the paying parent's numbers first.

  • Monthly gross income

    The paying parent's total monthly income before taxes — salary, regular overtime, commissions, or averaged self-employment income. If pay varies, use a recent average rather than one unusually high or low month.

  • Net resources (estimated)

    Texas applies guideline percentages to net resources, not gross income. The calculator subtracts estimated Social Security tax, Medicare tax, federal income tax, and any advanced deductions you enter to reach an estimated net-resources figure.

  • Children before the court

    The number of children in this case sets the guideline percentage — 20% for one child, 25% for two, and so on.

  • Other children supported

    If the paying parent also supports children from another relationship, the guideline percentage may be reduced through a multiple-family adjustment.

  • Health insurance and medical support

    Child health or dental insurance paid by the paying parent can be entered as an advanced deduction. Medical support obligations in a final order may also be handled separately from the base guideline amount — for example, one parent providing insurance while the other pays a cash medical support amount.

After you have a result, compare it with the income examples below and read why court orders sometimes differ. If parenting time is still being negotiated, estimate support separately from the custody calendar.

Texas Child Support Examples by Income

Parents often search by monthly income. The table below shows simplified planning estimates using the calculator's default tax assumptions and no other-children adjustment.

These examples use simplified estimates to show how guideline percentages work. They are not official calculations and may differ from a court order because of deductions, other supported children, medical support, high-income rules, or judicial discretion.

Monthly gross income Est. net resources 1 child 2 children 3 children
$3,000~$2,512~$502~$628~$754
$4,000~$3,350~$670~$838~$1,005
$5,000~$4,187~$837~$1,047~$1,256
$6,000~$5,025~$1,005~$1,256~$1,508
$7,000~$5,862~$1,172~$1,466~$1,759
$8,000~$6,700~$1,340~$1,675~$2,010
$9,000~$7,537~$1,507~$1,884~$2,261
$10,000~$8,375~$1,675~$2,094~$2,513

These are simplified estimates for comparison — not court calculations. Deductions, medical support, other supported children, and cap rules can change the result. Enter your numbers in the calculator above for a case-specific estimate.

Why the Calculator Estimate May Differ From a Court Order

A guideline-style estimate helps with budgeting and mediation prep. A court or the Attorney General may reach a different number after reviewing records.

Treat the calculator output as a starting conversation — gather pay stubs, tax returns, insurance costs, and existing orders before mediation or court.

FAQ

Texas child support FAQ

Texas guideline and income questions only — not custody calendars or overnight percentages.

How is child support calculated in Texas?

Texas guideline support starts with gross monthly income, subtracts allowable deductions to estimate net resources, then applies a percentage based on the number of children before the court. Other supported children, low-income rules, and court discretion can change the final amount.

What percentage of income goes to child support in Texas?

Standard guideline percentages are 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more children — applied to monthly net resources, not gross income.

How much is child support for one child in Texas?

For one child, guideline support is 20% of monthly net resources when no other supported children or adjustments apply. At $5,000 gross income with typical estimated deductions, that often lands near $800–850 per month before case-specific changes.

Does 50/50 custody eliminate child support in Texas?

No. Equal parenting time does not automatically eliminate child support. If one parent has higher net resources, guideline support may still apply even when overnights are split evenly.

What income counts toward child support in Texas?

Net resources include wages, salary, self-employment income, overtime, bonuses, commissions, and other income the paying parent receives, minus allowable deductions such as taxes and child health insurance.

When does child support end in Texas?

Support often continues until a child turns 18 or graduates from high school, whichever is later. Exceptions can apply for disabled adult children or other order-specific terms.

Can a court order more or less than the guideline amount?

Yes. Courts may deviate from guideline support when special medical needs, education expenses, high-income circumstances, or other proven facts justify a different amount.

Is this calculator legal advice?

No. This tool is for educational and planning purposes only. It is not legal advice, does not create an attorney-client relationship, and is not an official Texas court or Attorney General calculation.
