OKLAHOMA SUPPORT GUIDELINE
Oklahoma child support calculator & worksheet
The Oklahoma child support calculator estimates a basic obligation from combined gross monthly income and each parent’s income share. Open the worksheet to organize your figures, then compare its base result with the official OKDHS computation. Parenting-time credits and added expenses require separate handling.

How Oklahoma child support law works
Legal starting point. Oklahoma child support is governed by title 43 and the official computation form. The guideline begins with the parents’ combined gross monthly income and a schedule amount, then the worksheet applies the allocation and adjustments that fit the household. Read Oklahoma 43 O.S. §§ 118B–119.
How the guideline is calculated
The schedule selects the base obligation for income and child count, and the full computation form allocates it between the parents. Medical support, child care, parenting time, other-child adjustments, and credits are separate steps that should not be inferred from a simple lookup.
What this site’s worksheet covers
Uses the OKDHS Child Support Computation workbook CS Schedule sheet for 43 O.S. § 119. The official workbook uses the listed schedule row at or below combined gross monthly income, rounds basic support to a whole dollar, and rounds income shares to seven decimal places before allocation. Medical support, child care, parenting-time adjustments, qualified other-child adjustments and computation-form credits remain separate worksheet issues.
Documents that make the worksheet more useful
Oklahoma Child Support Computation and parenting-time and medical-support adjustments. Gather the records that support the income, parenting-time, insurance, child-care, and other adjustment entries that apply to the family. The calculator applies the guideline formula described above and identifies any listed worksheet line it does not compute.
For a filing or agreement, complete the official court forms linked on this page. They use the same guideline structure explained here, and the court applies it to the facts of the case.
Before you enter your numbers
Why does Oklahoma have a separate insurance premium worksheet?
The Oklahoma computation materials distinguish the cost attributable to the children from the total premium for a policy. The insurance calculation feeds the support computation along with other medical-support entries. Entering a family premium without following those instructions can overstate the child-related expense.
Prepare this: Bring the employer or insurer's coverage rates and identify everyone covered. Keep the insurance-premium calculation with the main Child Support Computation rather than entering an unexplained total.
Read the relevant official instructions: Oklahoma 43 O.S. §§ 118B–119.
These preparation notes explain one part of the state guideline. A new estimate does not change an existing order; a modification request does.
How Oklahoma cases actually get to a number
Determine combined gross monthly income as Oklahoma defines it, look up the table, allocate by share, then add medical and child-care items. Shared parenting is a defined Oklahoma computation, not a 50 percent shortcut.
Oklahoma uses a gross-income table under 43 O.S. section 119 and the OKDHS worksheet. Combined gross income selects the basic obligation before add-ons. That is a different path from neighboring states that use another model, so do not import a table, percentage, or overnight credit from somewhere else.
Parenting time in Oklahoma
When both parents have substantial time, Oklahoma’s shared-parenting calculation applies. Overnight thresholds in the current instructions control that path.
Costs Oklahoma usually treats separately
- Medical-support costs
- Work-related child care
- Extraordinary medical expenses

When Oklahoma courts leave the guideline
Income above the table, a child’s special needs, and other children in the home are typical deviation or adjustment issues. Imputed income appears often when a parent is voluntarily underemployed.

Questions about Oklahoma child support
How does this calculator use the OKDHS schedule?
The calculator applies the basic schedule from the OKDHS Child Support Computation workbook to the parents’ combined gross monthly income and divides that obligation by each parent’s income share. Credits, parenting-time lines and add-on expenses are completed on the official OKDHS computation, which also supplies the Department of Human Services forms.

Does Oklahoma child support use gross or net income?
The basic schedule uses combined gross monthly income under the Oklahoma guidelines. Both parents’ income figures determine their shares. Business earnings and allowable adjustments must follow the guideline definitions; do not substitute paycheck take-home pay or deduct personal household spending as a business expense.

Are parenting time, insurance and child care included?
The result here is the base schedule allocation. Parenting-time adjustments, medical support, child care, qualified other-child adjustments and computation-form credits are separate worksheet issues. A completed financial intake does not mean every recorded expense reduces the calculated amount. Compare those additional lines with the official computation before relying on a total.
