How Wyoming calculates child support
- Each parent’s net monthly income is gross income less income taxes, Social Security and Medicare, health coverage for dependent children, support paid for other children under earlier orders and mandatory pension deductions.
- The parents’ combined net income gives the total obligation from the tables in W.S. 20-2-304(a) (effective July 1, 2023): a base amount plus a percentage of income above the table line. It is shared by net income, and the parent the children do not live with pays their share.
- When each parent keeps the children overnight more than 25% of the year and both contribute substantially to their expenses, each parent’s share is multiplied by 150% and by the time the children spend with the other parent, and the amounts are offset. Wyoming’s official calculator does not let the result exceed the paying parent’s basic support. With split custody, a per-child amount is allocated by where each child lives and offset.
- A paying parent keeps a self-support reserve equal to the poverty guideline for one person, $1,330 a month since January 13, 2026: support is no more than their net income minus that reserve.
What the calculator asks
- How many children is the support for?
- Where do the children stay overnight?
- What percentage of overnights in a year are the children with you?
- Do both of you contribute substantially to the children’s expenses, beyond paying child support?
- How many of the children live with you?
- Your net income per month
- The other parent’s net income per month
- Are Social Security or veteran’s benefits paid to the children because of a parent’s record?
It never asks for names, Social Security numbers or account numbers, and your answers are not saved.
What the estimate leaves out
- Combined net incomes below $1,000 a month, and a paying parent with net income at or below the $1,330 self-support reserve
- Social Security or veteran’s benefits paid to the children on a parent’s record
- Child care, uninsured medical costs and other expenses, which the court weighs as reasons to deviate (W.S. 20-2-307(b))
- Overtime the court does not expect to continue, and income imputed to a parent who is voluntarily unemployed
- Deviations the court may make under W.S. 20-2-307
When a situation is outside what the calculator covers, it says so and points you to the official worksheet instead of guessing.
