Wyoming child support calculator

Wyoming follows the income-shares model. The idea is that a child should receive the same proportion of parental income they would have if the parents lived together. Both parents’ net monthly income is combined and applied to the presumptive tables, and each parent is responsible for the share that matches their percentage of the combined income. The noncustodial parent pays their share to the other.

The heart of the calculation is the presumptive-support tables in W.S. 20-2-304 — for each number of children (one to five) a set of income brackets gives a base amount plus a marginal percentage of the combined net monthly income above the bracket floor. Above $15,000/month the top bracket keeps applying its marginal rate, so the tables never simply cap.

To the presumptive obligation Wyoming adds work-related child care and the children’s health-insurance premium, which are shared in proportion to income. The combined figure is the total obligation, split by income share. A self-support reserve tied to the federal poverty line protects low-income paying parents (W.S. 20-2-304(f)), and below $1,000/month the tables bottom out.

When each parent keeps the children more than 25% of overnights, W.S. 20-2-304(c) multiplies the total obligation by 1.5 to reflect the duplicated cost of two households, then offsets each parent’s share by the time the children spend with the other, so the higher earner pays the difference. Because that needs the exact overnight split, this calculator computes the standard (primary-custody) obligation.

It combines both parents’ income, applies the W.S. 20-2-304 tables, adds child care and health insurance, and splits the total by income share. It does not compute net income from your pay stubs, run the shared-custody 1.5× offset, apply the self-support reserve in detail, add extraordinary expenses, or apply a deviation the court may order.
