Wyoming Child Support Calculator
Wyoming sets presumptive child support in Wyo. Stat. § 20-2-304, an income-shares model built on both parents' net income. The current tables took effect July 2023. This calculator applies the tables for one to 5 or more children, the shared responsibility formula when each parent has the children more than 25% of the year, and the self-support reserve.

This is a guideline estimate under Wyo. Stat. §§ 20-2-303, 20-2-304, 20-2-307 for informational purposes only — it is not legal advice and not a substitute for the official worksheet or a family-law attorney. Courts can deviate from guideline amounts based on statutory factors, and inputs like income determination or imputed income are ultimately decided by the court.

Net income and the tables
Wyoming starts from income from almost any source, then subtracts personal income taxes, Social Security, the cost of the children's health coverage, current support paid for other children, other court-ordered support and mandatory pension deductions; this calculator takes net income as entered. Each table has lines from $1,000 to $15,000 of combined net monthly income. For one child, the first line is 23% of income, and above $15,000 ($180,000 a year) the table adds 10.3% of everything over that line. Below $1,000 the calculator uses the first line's percentage.
Shared responsibility
When each parent keeps the children overnight more than 25% of the year and both contribute to the children's expenses, the total obligation is multiplied by 150%. Each parent's income share of that amount is multiplied by the percentage of time the children spend with the other parent, and the parent owing more pays the difference. Split custody, where each parent has at least one child, uses a separate per-child formula that this calculator does not cover.
Self-support reserve
If the paying parent's net income minus the self-support reserve is less than the support from the tables, support is set at that difference. The reserve is the federal poverty guideline for one person, $1,330.00 a month for 2026. Child care, health care needs and parenting time beyond the formula are grounds for the court to deviate rather than add-ons.
Frequently asked questions
Does Wyoming use gross or net income for child support?
Net income. Income is counted from almost any source, including wages, self-employment profit after business expenses, workers' compensation, unemployment and retirement benefits, then personal income taxes, Social Security, the children's health coverage, other current support and mandatory pension deductions are subtracted. Means-tested income such as SNAP and SSI is excluded, and overtime counts only if it is expected to continue.
How does shared custody work for child support in Wyoming?
Shared responsibility applies when each parent has the children overnight more than 25% of the year and both contribute to their expenses. The table amount is multiplied by 1.5, split by net income, cross-multiplied by the other parent's time, and the parent owing more pays the difference.
What is the self-support reserve in Wyoming?
The current federal poverty guideline for one person, $1,330.00 a month for 2026. When the paying parent's net income minus the reserve is less than the table amount, support is set at that difference.
What if combined net income is above $15,000 a month?
The tables keep going: the $15,000 line gives a base amount plus a marginal percentage of anything over $15,000 ($180,000 a year), from 10.3% for one child upward. The court can deviate if the result is unjust or inappropriate.
Does Wyoming add child care to child support?
Not as a formula add-on. The cost of necessary child day care is one of the factors the court considers when deciding whether to deviate from presumptive support, along with special health and educational needs and the time the child spends with each parent.
What does this calculator leave out?
Converting gross pay to net income, imputed income, split custody, Social Security or veterans benefits paid for the child, and deviations. Wyoming courts publish child support computation forms for the official calculation.
