How Child Support Is Calculated in Oregon
Factors That Affect Child Support in Oregon
Technical details and legal basis
Oregon uses the Income Shares model (Oregon Child Support Guidelines (ORS 25.275)) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
Important Notes for Oregon
- • Oregon uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
- • Each parent's share of the obligation is proportional to their percentage of the combined gross income.
- • Oregon applies a parenting time credit when the non-custodial parent has the children for more than 25% of overnights per year (approximately 92 nights).
- • The court may consider additional factors including the cost of living in each parent's area, transportation costs for parenting time, and the child's special needs.
Example Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
Step 4: Multiply by Parent A's share (62.5%).
Adjustments for health insurance, child care, and parenting time may apply.
