Wyoming Child Support Calculator
Estimate Wyoming child support for 2026 using the Income Shares guideline model under Wyo. Stat. §§ 20-2-301 to 20-2-315. Enter both parents' incomes and the parenting-time split to see what you may owe or receive.
Wyoming follows the Income Shares model under Wyo. Stat. §§ 20-2-301 to 20-2-315. The court combines both parents' monthly gross incomes, looks up the basic support obligation on the state's guideline schedule for that income level and number of children, then prorates the obligation between the parents according to each parent's percentage share of the combined income.
Wyoming uses a shared-care formula, so parenting time can lower the support number once the paying parent has a meaningful share of overnights. The grounding facts note that shared-custody calculations apply when the obligor has at least 40 percent of the overnights. Below that level, parenting time usually does not change the basic obligation, though a judge can still consider it. Because the math swings sharply around the overnight threshold, the calculator on this page is only an estimate, and the official worksheet controls.
Wyoming treats the cost of the child's health insurance premium as part of the support calculation rather than as a side payment. Under the Income Shares model, this expense is added in and then split between the parents in proportion to each parent's percentage share of the combined income. The parent who actually pays the premium generally gets credit for it. This page estimates the split, but the official Wyoming worksheet and a licensed attorney control the final figure.
Work-related child care and daycare costs are treated as an add-on to the basic Wyoming support obligation. Like health insurance, these costs are folded into the calculation and divided between the parents according to each parent's percentage share of the combined income, so both parents share the daycare expense rather than one parent carrying it alone. The calculator here gives a rough estimate only, and the controlling number comes from the official worksheet, not this tool.
Wyoming's guideline number is presumed correct, but a district court judge may deviate when applying the guideline would be unjust or inappropriate for the specific family. The parent asking for a different amount carries the burden of showing why, and the court must put written findings in the order explaining the reason for any deviation. Factors can include a child's special needs or other circumstances the standard formula does not capture. This page cannot predict a deviation, so treat its output as an estimate and confirm with the official worksheet or an attorney.
Frequently asked questions
How is child support calculated in Wyoming?
Wyoming uses the Income Shares model under Wyo. Stat. 20-2-301 to 20-2-315. The court combines both parents' incomes, looks up the basic support obligation on the state guideline schedule for that income level and number of children, then prorates it between the parents by each parent's percentage share of the combined income. Wyoming works from net monthly income, meaning gross income from all sources reduced by allowable deductions. The Wyoming Child Support Enforcement Program, part of the Department of Family Services, administers cases. The calculator on this page is an estimate only. The official worksheet and a licensed attorney control your actual number.
Is there an official Wyoming child support worksheet I have to use?
Yes. Wyoming has an official guideline worksheet, and it is the controlling form, not any online estimator. Judges and the Wyoming Child Support Enforcement Program rely on that worksheet to combine both parents' net incomes, apply the state schedule, and prorate the basic obligation by income share. The worksheet is also where health insurance, child care, and shared-custody adjustments are entered and calculated. You can reach Wyoming's child support resources through the Department of Family Services at dfs.wyo.gov. The tool on this page mirrors the general method but is only an estimate, so complete the official worksheet or speak with an attorney for a binding figure.
What income counts when figuring Wyoming child support?
Wyoming starts from net monthly income, which is gross income from all sources reduced by certain allowable deductions. Under the grounding facts for this state, those deductions include federal and state income taxes, FICA, mandatory retirement, mandatory union dues, and any existing court-ordered support. Because Wyoming counts income from all sources, items like wages, self-employment earnings, bonuses, and overtime can be included before deductions are applied. How irregular pay is averaged can vary by case. This page gives an estimate based on the numbers you enter, but the official worksheet and a Wyoming attorney determine which income and deductions actually count.
How do 50/50 and shared parenting affect support in Wyoming?
Wyoming applies a shared-care formula, so the overnight split directly affects the number. The grounding facts state that shared-custody calculations kick in when the paying parent has at least 40 percent of the overnights, which covers many 50/50 and near-equal arrangements. In those cases the basic obligation is adjusted to reflect that both households are directly supporting the child a large share of the time. Below that overnight level, the standard Income Shares result usually applies. The swing around the threshold can be large, so use this page only as an estimate and rely on the official worksheet for your true figure.
Can I change a Wyoming child support order if my income changes?
Yes. In Wyoming you can file a motion to modify in district court or request a review through the Child Support Enforcement Program. The grounding facts state that a 20 percent change between the existing order and a new guideline calculation creates a presumption of substantial change, which is the trigger most parents rely on. That presumption helps when a job loss, raise, or new parenting schedule shifts the math. Wyoming runs the modification through the same Income Shares method as the original order. The estimate on this page can show you whether you are near that 20 percent line, but the official worksheet controls.
When does child support end in Wyoming?
Under Wyoming law, child support generally ends at age 18 or upon high school graduation, whichever is later, but not past age 20. So a child who is still finishing high school at 18 can continue to receive support until graduation, with the cutoff at age 20. Wyoming also allows continuing support for a disabled adult child where the circumstances justify it. Support does not always stop automatically, so check your specific order and confirm with the Child Support Enforcement Program or an attorney. This page does not determine a termination date and is only an estimate of the support amount.
How does Wyoming enforce a child support order if a parent stops paying?
The Wyoming Child Support Enforcement Program, run by the Department of Family Services, has several tools. The grounding facts list immediate income withholding, tax refund intercept, license suspension, lien filings, credit reporting, and contempt referrals. Income withholding is typically automatic, meaning support comes straight out of the paying parent's wages. Past-due amounts, called arrears, generally remain owed until paid, and enforcement can continue even after the current obligation ends. You can reach Wyoming's program through dfs.wyo.gov. This page only estimates the ongoing support amount and does not calculate arrears or penalties, so contact the program or an attorney for collection questions.
