How the Income shares Model Works

1

Determine Combined Income

Add both parents' adjusted gross income together to get the combined income figure.

2

Look Up Base Obligation

Using Wyoming's guidelines table, find the base child support amount for your combined income and number of children.

3

Prorate Between Parents

Each parent's share is proportional to their income. If Parent A earns 60% of the combined income, they are responsible for 60% of the obligation.

4
