Child support in Wyoming.
What the state’s own guideline says, where the number comes from, and the one figure that moves it more than anything you will argue about.
See a different stateWyoming
Wyoming combines both parents' net monthly incomes and applies a percentage from a statutory table — the percentage falls as combined income rises, and it is applied marginally, band by band. That total is then split between the parents in proportion to their net incomes. Because the table is written into the statute rather than into a rule, the numbers only change when the legislature changes them.
How Wyoming works out the number
Authority: Wyo. Stat. §§ 20-2-301 through 20-2-315; the presumptive child support tables are at § 20-2-304, definitions at § 20-2-303, deviation at § 20-2-307, modification at § 20-2-311There is no overnight-count credit in Wyoming. Shared custody under Wyo. Stat. § 20-2-304(c) multiplies the total child support obligation by 150 percent, divides it proportionally, and has the parent who owes more pay the difference. Split custody under § 20-2-304(d), where each parent has physical custody of at least one child, calculates per child and offsets. Note that the old extended-visitation abatement in § 20-2-304(b) was repealed by Laws 2018, ch. 42.
Use the state’s own calculator, not ours
Wyoming publishes this itself, free. It is called DIVCP 13, "Child Support Computation Form & Net Income Calculation" (Wyoming Judicial Branch; effective July 1, 2023, last revised May 2025). We are not going to build a competing calculator and ask you to trust it — this is the one a judge will recognize.

What counts as income
Wyo. Stat. § 20-2-303 defines income as "any form of payment or return in money or in kind to an individual, regardless of source" — which is what captures overtime, bonuses and a second job — including wages, disability, unemployment and retirement benefits, but excluding means-tested assistance such as SSI. Net income is income minus "personal income taxes, social security deductions, cost of dependent health care coverage for all dependent children, actual payments being made under preexisting support orders for current support of other children." The court's worksheet lets self-employed parents also deduct unreimbursed business expenses.
When a judge can treat you as earning more
The court may assign earning capacity to a parent who is "voluntarily unemployed or underemployed," considering prior work history, education, local wage rates and realistic earning ability. The state worksheet builds in a minimum-wage default for a parent capable only of minimum wage work: "Imputed Net Monthly Income (Custodial Parent): $1,185.67 per month" and $1,141.25 per month for the noncustodial parent.
If you do not earn much
The Wyoming Judicial Branch publishes the current self-support reserve on its self-help forms page: "The Self-Support Reserve as of 1/13/2026 is: $1330.00." The statutory tables themselves begin at $1,000 of combined net monthly income; we found no fixed statutory minimum order amount.
Childcare and health insurance
The cost of dependent health care coverage for all dependent children is subtracted from income before the percentage is applied — so it is handled as a deduction, not an add-on. Day care costs are a listed deviation factor under Wyo. Stat. § 20-2-307 rather than an automatic addition.
Private school, special needs, activities
Handled through the deviation factors in Wyo. Stat. § 20-2-307, which include the child's age, daycare costs, special needs, the availability of health insurance and the parents' time-sharing arrangement.
When a judge can depart from the number
Wyo. Stat. § 20-2-307 requires a "specific finding that the application of the presumptive child support would be unjust or inappropriate in that particular case." Section 20-2-308 adds that no order establishing or modifying support may be entered "unless financial affidavits on a form approved by the Wyoming supreme court which fully disclose the financial status of the parties have been filed."
Two things stand out. Wyoming gives you no credit for overnights the way most states do — the extended-visitation abatement was repealed in 2018, and unless you are in a true shared or split custody arrangement under § 20-2-304(c) or (d), extra parenting time does not move the number by itself. And every three years you can ask for a fresh calculation without proving anything changed. Put it on your calendar.
Later on
When it ends
Wyo. Stat. § 20-2-313: "An on-going child support obligation terminates when the: (i) Parents marry or remarry each other; (ii) Child dies; (iii) Child is legally emancipated; or (iv) Child attains the age of majority." Age of majority is defined by cross-reference to Wyo. Stat. § 14-1-101(a) or § 14-2-204(a), whichever applies.
College and support after 18
We could not confirm whether a court here can order support for college.
Changing the amount later
Wyo. Stat. § 20-2-311 allows modification when the "support amount will change by twenty percent (20%) or more per month from the amount of the existing order." Separately, a court must review and adjust the order every three years on request, without requiring any showing of changed circumstances.
How far back a change can reach
We could not confirm this state’s rule on how far back an order or a change can be applied. It matters: in some states the clock starts the day you file, so filing late costs money you do not get back.
What we could not confirm
- We could not confirm from the statute whether Wyoming continues support past age 18 for a child still in high school — the statute defines the age of majority by cross-reference to another title we did not read. We also could not confirm Wyoming's rules on interest on arrears or license suspension, or whether a court can order support for college. Run your figures through the state calculator at childsupport.wyoming.gov and check the current self-support reserve on the Judicial Branch self-help forms page, since it changes.
- 3 official pages we tried to read refused automated access. We did not try to get around the block, so some detail above comes from a different official source rather than the one we would have preferred.
