Child Support Calculator in Oregon: What You Should Know
Oregon uses the Income Shares Model through the Oregon Child Support Guidelines, combining both parents' adjusted gross incomes to determine the obligation. Each parent covers a proportional share, and Oregon applies a parenting time credit that scales with the number of overnights, so a parent with substantial time pays less. The calculation also factors in childcare, health care, and a self-support reserve that protects a low-earning parent. There is no flat income cap on the guideline.
Key point: Oregon applies the Income Shares Model with a parenting time credit that scales with overnights and a self-support reserve for low earners.

Child Support in Oregon - Frequently Asked Questions
How is child support calculated in Oregon?
Oregon uses the Income Shares Model to calculate child support. Both parents' gross incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income.
Can child support be modified in Oregon?
Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in Oregon typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in Oregon?
Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.
Is there an income cap for child support in Oregon?
Oregon does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.
How long does child support last in Oregon?
Child support in Oregon typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.
