Wyoming Child Support Calculator

Wyoming child support depends on both parents’ net incomes (pay after taxes and certain deductions), the number of children, and how many nights the children spend with each parent. With one child, when one parent earns $5,000 a month before taxes and the other earns $3,000, the higher earner pays about $757 a month if the child lives mostly with the other parent.

Each row turns weekly pay into monthly pay (× 52 ÷ 12), then subtracts estimated federal income tax and Social Security and Medicare, the same way the calculator above does. At $500 a week and below, amounts are lowered so the paying parent keeps $1,330 a month after taxes (see the low-income section below). The amounts start from Wyoming’s tables, which give the total support for both parents together by their combined net income. The full tables, from July 2023, are in Wyo. Stat. §20-2-304(a).

Wyoming uses an income shares formula. It adds both parents’ monthly net incomes, finds the total support for that income in the state’s tables, and splits it by each parent’s share of the income. The parent the children spend less time with pays their share to the other parent.

The rules are in Wyo. Stat. §§20-2-303 and 20-2-304:

1. Find each parent’s net income. Start with income from all sources (after business expenses for the self-employed) and subtract income taxes, Social Security and Medicare, required retirement contributions, the children’s health insurance, and court-ordered support paid for other children or a former spouse. Overtime counts only if it is likely to continue. POWER, SNAP, SSI, and Pell grants don’t count. Wyoming has no state income tax.
2. Add the two net incomes.
3. Find the total support in the tables. Use the line at or just below the combined income, and take that line’s base amount plus a percentage of the income above it.
4. Split it by income share. A parent with 60% of the combined income has a 60% share.
5. Apply the shared custody formula if each parent has 92 or more overnights a year.
6. Make sure the paying parent keeps $1,330 a month to live on.

Example

One parent has a net income of $4,000 a month and the other $2,000, so their combined income is $6,000. The one-child table gives $965 plus 11.8% of the $1,500 above $4,500, or $1,142. The higher earner has two thirds of the income, so with the child living mostly with the other parent, they pay about $761 a month. These are incomes after taxes. The calculator above starts from pay before taxes and estimates the taxes for you.

Yes, once each parent has the children overnight more than 25% of the year (92 or more nights). Support drops more as the time gets closer to equal. With one child, when one parent earns $5,000 a month before taxes and the other earns $3,000, the higher earner pays $757 a month with 91 or fewer nights, about $660 at 92, about $382 at 146 (40%), and about $219 at 50/50.

Under Wyo. Stat. §20-2-304(c), the formula multiplies the total support by 150%. It then works out what each parent owes for the time the children spend with the other parent, and the parent who owes more pays the difference. The formula also requires both parents to pay a substantial part of the children’s costs on top of child support. A judge decides whether they do; the calculator above assumes they do.

Wyoming doesn’t add child care costs to the table amount. A judge can order more or less than the table amount to cover necessary day care.

Day care is one of the factors listed in Wyo. Stat. §20-2-307(b). Bring receipts and ask the judge to address the cost in the order.

Every Wyoming order must cover the children’s medical needs. One or both parents must put the children on health insurance when it costs no more than 5% of that parent’s income before taxes. The order also says how the parents split bills that insurance doesn’t pay. The parent who pays the children’s premium subtracts it from their income before support is figured.

• Coverage: insurance is required when it costs no more than 5% of the insuring parent’s income before taxes and the children can use it where they live, under Wyo. Stat. §§20-2-401 and 20-2-406.
• Uncovered bills: the order either makes both parents responsible or sets each parent’s share. Wyoming’s child support policy manual explains how this is enforced.
• Medicaid and Kid Care CHIP: children without other coverage may qualify for Wyoming Medicaid or Kid Care CHIP.

If the children live with you and you get POWER (Wyoming’s cash assistance), you have to help the state get child support from the other parent, for example by naming them and helping prove paternity. The state keeps the support collected to repay the assistance, except up to $100 a month for one child or $200 for two or more, which goes to your family without lowering your POWER. Food stamps (SNAP) don’t require this.

• POWER: no benefits are paid until you help, unless you have a good reason, such as a risk of violence, under Wyo. Stat. §42-2-103(e)(vii). The Department of Family Services can also waive requirements for a parent fleeing domestic violence.
• The $100 or $200: it comes from support actually collected each month, under Wyoming’s child support policy manual, 14.4.
• Agreements: parents can’t agree to less than the table amount while any of the children get POWER, Medicaid, SNAP, or SSI, under Wyo. Stat. §20-2-307(d).
• SNAP: USDA lists Wyoming as a state that doesn’t require help with child support to get food stamps.

The Wyoming child support guide covers how this works.

Support can’t leave the paying parent with less than $1,330 a month of net income to live on (the 2026 federal poverty line for one person). Wyoming has no minimum order, so a paying parent with net income of $1,330 or less owes $0 under the formula.

• Paying parent above $1,330: support is whichever is lower: their share, or their income above $1,330. This rule is in Wyo. Stat. §20-2-304(f), which calls the $1,330 the “self-support reserve.” A paying parent with net income of $1,500 a month pays at most $170.
• Shared custody: the same limit applies to whichever parent ends up paying under the shared custody formula.
• Earning less by choice: a judge can base support on income a parent could earn, looking at their work history, education, and local jobs and wages, under Wyo. Stat. §20-2-307(b)(xi).

The amount follows the federal poverty guidelines, which change each year. The Wyoming Judicial Branch child support page lists the current figure ($1,330 since January 13, 2026).

No. Above $15,000 a month in combined net income, the tables keep adding a percentage of the extra income, from 10.3% for one child to 22.2% for five or more.

For one child, the top line is $2,157 plus 10.3% of income over $15,000, under Wyo. Stat. §20-2-304(a). At $20,000 combined, that is $2,672 for both parents together.

Yes, if the judge finds the table amount would be unfair. The order must state the table amount and the reasons for the different one.

Factors in Wyo. Stat. §20-2-307(b) include the child’s age, day care costs, special health and education needs, other children a parent supports, the cost of travel for visits, employer health insurance, the time the children spend with each parent, and whether a parent is earning less by choice. If the parents don’t agree on a different amount and the judge keeps the table amount, the parent who asked for the change can be ordered to pay the other’s attorney fees and court costs, under Wyo. Stat. §20-2-307(c).

Either parent can ask for a review every three years without showing any change, or sooner if the table amount would change by 20% or more or circumstances have changed a lot. Keep paying the current order until a judge changes it.

• Sooner than three years: once the order is more than six months old, if the table amount would change by 20% or more a month, or at any time after a big change. Starting POWER, Medicaid, SNAP, or SSI counts as one.
• Through the Child Support Program: ask your local child support office for a review (open a case first if you don’t have one). If a change is warranted, the office files the petition.
• Through the court: file a Petition for Modification of Child Support in district court.
• Start date: a new amount can go back only to the date the other parent was served with the petition, unless both parents agree otherwise.

The rules are in Wyo. Stat. §20-2-311. The Wyoming child support guide walks through each step.

Yes. The Department of Family Services runs the Wyoming Child Support Calculator, and the courts’ Child Support Computation Form does the same math on paper.

Use the Wyoming Child Support Calculator for a full estimate, including when each parent has at least one of the children. The courts’ Child Support Computation Form and Net Income Calculation is the form for a court case, and it recommends the online calculator.
