How child support is calculated in Wyoming
Wyoming’s statute gives tables, by number of children, that turn the parents' combined net monthly income into a total obligation (a base amount plus a marginal percentage of income above each step), which is then divided in proportion to each parent’s net income. A 150% shared-responsibility formula applies when each parent keeps the children overnight more than 25% of the year.[1]

The rules behind Wyoming’s numbers
The guideline is Wyo. Stat. § 20-2-304(a). Open each rule to read the exact words.
- Income counted
Net income: income less taxes, social security, children’s health coverage and listed deductions
Net income is income from all sources minus personal income taxes, social security, the cost of the children’s health coverage, support actually paid for other children, other court-ordered support and mandatory pension deductions.[1]
Official text · Wyo. Stat. § 20-2-303(a)(iii)
“"Net income" means income as defined in paragraph (ii) of this subsection less personal income taxes, social security deductions, cost of dependent health care coverage for all dependent children,”
- Percentages
One child: $230 + 23.0% over $1,000 … $2,157 + 10.3% of anything over $15,000
For one child, the table starts at $1,000 of combined net monthly income ($230 plus 23% above $1,000) and ends at $15,000 ($2,157 plus 10.3% of anything above $15,000).[1]
Official text · Wyo. Stat. § 20-2-304(a)(i)
“$15,000.00 14.4 $2,157.00 + 10.3% of anything over $15,000.00”
- Top of the guidelines
No cap: marginal percentage applies to all income above $15,000
The top step of each table applies its marginal percentage to anything over $15,000 of combined net monthly income, so there is no income ceiling.[1]
Official text · Wyo. Stat. § 20-2-304(a)(i)
“$1,000.00 23.0 $230.00 + 23.0% over $1,000.00”
- Shared parenting time
Each parent more than 25% of overnights: total obligation × 150%, prorated and offset
When each parent keeps the children overnight more than 25% of the year and both contribute substantially to expenses, the obligation is multiplied by 150%, split by net income, multiplied by the time with the other parent, and offset.[1]
Official text · Wyo. Stat. § 20-2-304(c)
“When each parent keeps the children overnight for more than twenty-five percent (25%) of the year and both parents contribute substantially to the expenses of the children in addition to the payment of child support, a shared responsibility child support obligation shall be determined”
- Low income
Self-support reserve = federal poverty line for one person
If the payer’s net income minus the self-support reserve (the federal poverty line for one person) is less than the table amount, support is set at that difference.[1]
Official text · Wyo. Stat. § 20-2-304(f)
“If the difference between the obligor's net income and the self-support reserve is less than the support obligation as calculated from the tables in subsection (a) of this section, the support obligation shall be set using the difference between the obligor's net income and the self-support reserve.”
- Review cycle
Reviewed at least every four years by the Department of Family Services
The Department of Family Services must review the presumptive child support at least once every four years.[1]
Official text · Wyo. Stat. § 20-2-306
“at least once every four (4) years thereafter, the department of family services shall review the presumptive child support established under this article”
