What is the OAG Child Support Calculator?
The oag child support calculator is a specialized tool designed to help parents and legal professionals estimate monthly child support obligations according to the Texas Office of the Attorney General (OAG) guidelines. In Texas, child support is primarily determined by the non-custodial parent's "net resources."
Who should use it? This tool is essential for parents going through a divorce, legal separation, or a modification of an existing support order. It helps set realistic expectations for financial planning. A common misconception is that child support is based solely on gross income; however, the oag child support calculator accounts for taxes, social security, and mandatory health insurance costs to find the true net resource figure.
OAG Child Support Calculator Formula and Mathematical Explanation
The calculation follows a specific multi-step derivation mandated by the Texas Family Code. First, we determine the Gross Monthly Income, then subtract mandatory deductions to arrive at Net Monthly Resources.
The core formula is:
Support Amount = (Net Monthly Resources × Guideline Percentage)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Gross Income | Total monthly earnings before tax | USD ($) | $0 – $20,000+ |
| Net Resources | Income after taxes and insurance | USD ($) | Capped at $9,200 |
| Guideline % | Percentage based on child count | % | 14.75% – 40% |
| Medical Support | Cost of health/dental premiums | USD ($) | $50 – $800 |
Practical Examples (Real-World Use Cases)
Example 1: Single Child Case
A non-custodial parent earns $4,000 gross per month. After standard tax deductions (approx. 20%) and paying $200 for health insurance, their net resources are $3,000. Using the oag child support calculator for one child (20%), the estimated support is $600 per month.
Example 2: Multiple Children with Other Obligations
A parent earns $6,000 gross. They have 2 children in the current case but also support 1 child from a previous marriage. The adjusted percentage for 2 children when 1 other child exists is 22.50%. If net resources are $4,500, the support would be $1,012.50.

Key Factors That Affect OAG Child Support Calculator Results

- Other Legal Obligations: Supporting children from other relationships reduces the percentage applied to the current case.
