§ How Oregon calculates support
Oregon uses the Income Shares Model on combined ADJUSTED gross monthly income, with the basic obligation read from the Scale of Basic Support Obligations (OAR 137-050-0725). The scale caps at $30,000/month combined; obligations for more than ten children equal the ten-child amount. A self-support reserve applies, the minimum order is $100/month, and parenting-time credits reduce the obligation based on overnights.

✦ How to open or modify a case in Oregon
- Determine each parent's gross income from all sources.
- Subtract allowed deductions (union dues, own health insurance, spousal support paid, non-joint children) to get adjusted income.
- Combine both adjusted incomes.
- Look up the basic support obligation on the Scale of Basic Support Obligations by combined income and number of children.
- Apply parenting-time credits based on overnights and add the child's health insurance and childcare.
- Split the obligation by each parent's percentage share of adjusted income.
◈ Illustrative examples
Scenario: Combined adjusted gross monthly income $5,000; one child. Scale basic obligation ~$664/month.
Walk-through: Obligor earns 60%, so pays 60% x $664 = about $398/month. For two children the scale amount is ~$953, so the obligor pays about $572/month (before credits/add-ons).
Takeaway: Oregon's scale gives the total base obligation; the paying parent covers only their income-share percentage.
