How this Texas estimate works

The page follows the public Texas OAG calculator script instead of using a generic nationwide formula.

1. Convert income to annual and monthly amounts
The selected frequency is converted to annual gross income. Hourly pay uses hours per week and applies 1.5x overtime above 40 hours.
2. Subtract payroll taxes and monthly deductions
OASDI, Medicare, and federal income taxes are computed with the same published constants shown by the Texas OAG calculator. Medical, dental, union, and state tax deductions are then subtracted.
3. Apply the Texas guideline percentage
The page applies the Texas low-income or standard guideline table, then adjusts the percentage for children outside this action before calculating the projected monthly obligation.

Important Texas notes

Important Texas notes

This estimate is for a single source of income, matching the official Texas OAG page.

The actual amount set or approved by the court may differ.

This page does not calculate support above the published $11,700 net-resource cap used by the Texas OAG calculator.

The Texas low-income guideline table is used when the calculated net resources used for support are below the published threshold.

Texas child support FAQ

Is this the official Texas child support calculator?
No. This page is not an official government tool. It mirrors the public Texas OAG monthly child support calculator's inputs and published constants so you can estimate the same monthly support workflow.
Does this Texas estimate work for more than one source of income?
No. The official Texas OAG page states that the calculator provides an estimate for a single source of income, and this page keeps the same boundary.
What counts as children outside this action?
Use this field for other children for whom the person paying support has a legal duty to provide support. The Texas formula uses this count to reduce the guideline percentage through a multiple-family adjustment.
Does this page calculate support above the Texas cap?
No. Like the Texas OAG calculator, this page applies the published $11,700 monthly net-resource cap when computing the projected obligation.
Why does the page show a low-income guideline percentage?
Texas publishes a separate low-income guideline table. When the net resources used for support fall below the published threshold, the lower table is used instead of the standard percentage table.
