Child Support Calculation Worksheet - Oregon

CHILD SUPPORT CALCULATION PREPARATION WORKSHEET

Do Not File This Worksheet as the Official Calculation

Use the current Oregon Child Support Guidelines Calculator and file the calculator printout or worksheet required by the court or agency. As of this verification, the official calculator identifies itself as Version 3.6.13.

The calculation sequence is controlled by OAR 137-050-0710 and related rules. This preparation worksheet collects inputs; it must not be used to hand-calculate or override the official result.

1. Case and Parties

Court or agency: [________________________________]

County: [________________________________]

Case number: [________________________________]

Caretaker, if a child lives with a nonparent: [________________________________]

2. Joint Children

3. Income Inputs

OAR 137-050-0715 defines income as actual or potential gross income determined under that rule. Actual income may include wages, commissions, recurring overtime, bonuses, pensions, unemployment or workers' compensation benefits, Social Security or veterans' disability income, self-employment income after allowed costs, and other listed sources. The rule also contains exclusions and limits on imputing potential income.

Do not automatically impute full-time minimum wage. The current rule requires a fact-specific potential-income analysis and has protected categories in which potential income may not be imputed.

4. Adjusted-Income Inputs

OAR 137-050-0720 directs the calculator to begin with guideline income and then account for mandatory union or labor-organization contributions, the parent's own health-insurance cost, court-ordered monetary spousal support owed or received, and an eligible non-joint-child deduction.

5. Parenting-Time Inputs

OAR 137-050-0730 generally uses a current written parenting-time agreement or court order and averages the number of overnights over two consecutive years. The rule contains alternate methods for significant nonovernight blocks, split custody, no current written schedule, and actual parenting time found by a court or administrative law judge.

6. Childcare Costs

OAR 137-050-0735 permits qualifying childcare costs for a child who is under age 13 or disabled when the costs are related to employment, job search, or education or training necessary to obtain a job. Use actual documented costs, subject to the current rule's reasonableness and maximum-cost provisions.

7. Medical Support

OAR 137-050-0750 addresses health-care coverage, cash medical support, reasonable cost, and credits. The rule states that the basic obligation includes ordinary unreimbursed medical costs of $250 per child per year but not health-coverage costs or extraordinary medical expenses.

Extraordinary unreimbursed medical expense information: [________________________________]

8. Social Security or Veterans Benefits

ORS 25.275(4) and OAR 137-050-0740 govern specified dollar-for-dollar reductions for benefits paid to a child because of the obligor's disability or retirement. Identify the benefit source and beneficiary precisely.

9. Current Self-Support Reserve and Minimum Order

The current OAR 137-050-0745, effective July 1, 2026, uses a self-support reserve of $1,729 and states that it will be reviewed and updated annually. Do not reuse this figure after a new effective rule date without rechecking the official rule.

OAR 137-050-0755 generally creates a rebuttable $100 minimum-order presumption but contains exceptions. Let the current calculator and decision-maker apply those provisions.

10. Presumptive Result

Attach the current official calculator result.

11. Rebuttal or Agreed Amount

ORS 25.280 presumes the formula amount is correct. A different amount requires the written or on-record finding the statute and OAR 137-050-0760 require. The rebuttal criteria include, among other matters, other available resources, necessities, net income after required withholding, ability to borrow, other dependents, special hardship, the child's needs, tax consequences, and household financial advantage.

☐ No rebuttal requested.

☐ Rebuttal requested. Proposed amount: $[________]

Evidence and specific reason the formula result would be unjust or inappropriate: [________________________________]

☐ Agreed amount proposed under OAR 137-050-0765, with required findings and documentation: [________________________________]

12. Preparation Checklist
