How Oregon Calculates Child Support

Oregon calculates child support using the Income Shares Model as defined in ORS §107.105 and OAR 137-050. Both parents' gross incomes are combined to determine the total support obligation from the state schedule. Each parent's share is then allocated proportionally based on their percentage of the combined income.

Health insurance premiums for the child and childcare costs are added to the base obligation. Oregon is notable for its consideration of post-secondary education costs, which may extend the support obligation beyond the child's 18th birthday. The state also maintains a self-support reserve of $1,152 per month (2024) to ensure the obligor retains enough for their own basic needs.

Oregon provides shared custody adjustments and allows for rebuttal of the guideline presumption when justified by the specific circumstances of the case. Courts have discretion for high-income cases above the schedule.
