How Is Child Support Calculated in Oregon?

Oregon wants your children to have the same financial support as if you were living together. The state combines both your incomes, uses a chart to find a total support amount, and then divides that responsibility between you based on your percentage of the combined income.

Understanding Oregon's Shared Custody Rules

In Oregon, when a child spends at least 92 overnights per year with each parent (about 25% of the time), a different formula is used. This 'parenting time credit' calculation acknowledges the higher, duplicated costs of two households and often results in a lower support payment.
