  • Each parent's share of the obligation is proportional to their percentage of the combined gross income.

Example Child Support Calculation in Oregon

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined monthly income: $5,000 + $3,000 = $8,000

Step 2: Parent A's income share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation from the guidelines schedule for $8,000 combined income and 2 children.

Step 4: Multiply the basic obligation by Parent A's share (62.5%) to determine their payment.

Note: Additional adjustments for health insurance, child care, and parenting time may apply.

Frequently Asked Questions About Oregon Child Support

How is child support calculated in Oregon?
Oregon uses the Income Shares model. Both parents' gross incomes are combined, and a basic child support obligation is determined from the state schedule. Each parent pays their proportional share based on their percentage of the combined income. Adjustments are made for health insurance, child care costs, and the parenting time schedule.
How does parenting time affect child support in Oregon?
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 credit increases as the number of overnights increases, reducing the child support obligation to reflect the direct costs the non-custodial parent bears during those overnights.
What income counts for Oregon child support?
Oregon uses gross income from all sources, including wages, salaries, commissions, bonuses, self-employment income, workers' compensation, unemployment benefits, Social Security, pensions, rental income, and investment income. The court may also impute potential income to a parent who is voluntarily underemployed or unemployed.
Can Oregon child support be modified?
Yes, child support in Oregon can be modified if there has been a substantial change in circumstances since the last order, or if the existing order has been in effect for at least three years. The Oregon Child Support Program also conducts periodic reviews. A change of at least 15% from the current order typically justifies a modification.
How long does child support last in Oregon?
In Oregon, child support generally continues until the child turns 18. However, if the child is still attending school (including high school or an equivalent program), support continues until age 21. Support may also be extended for a child with a disability who requires ongoing care.
