Oregon Child Support Calculator
Free Oregon child support calculator using the income-shares model. Estimate monthly payments based on both parents' income and custody schedule.
How This Calculator Works
Calculation methodology and assumptions
Oregon uses the income-shares model for calculating child support. Both parents' incomes are combined, then each parent's share of the total obligation is based on their percentage of combined income. The custodial parent's share is presumed spent directly on the child. This calculator provides an estimate — actual court orders may vary based on additional factors like extraordinary medical costs, educational expenses, and judicial discretion.
Key State Information
