Inputs you need for Alimony Child Support in Oregon

Inputs you will need
To run the DocketMath calculator for Alimony + Child Support in Oregon (US-OR), gather the kinds of facts that typically drive the court’s analysis: income (for both parties and possibly taxes/deductions) and parenting time (for child support). You’ll also want any information about insurance and certain child-related expenses that could be included in the tool’s Oregon-aware rules.
Use this checklist as your starting point. If you don’t have an exact number yet, mark it as “estimate pending” and plan to update the run once you have paystubs, tax returns, or a finalized parenting-time schedule.
Gentle note: This is for planning and scenario comparison—not legal advice. Support outcomes can vary based on case-specific facts and how a court ultimately values income and parenting time.

Child support-related inputs (Oregon)
Note: DocketMath can only calculate with what you enter. If you use rough estimates now, expect the outputs to change meaningfully after you replace estimates with verified documents and an accurate parenting-time schedule.
Consistency checks (do this before running)
Where to find each input
Getting accurate numbers is mostly a documentation task. Below are common sources you can use—pick what matches your case and the data you already have.
Most inputs live in the case file, contracts, or docket entries. Dates usually come from the triggering event notice; rates and caps come from governing documents or statute; and amounts come from the ledger or judgment. Record the source for each value so the run is reproducible.
Income (used for both alimony and child support)
- **Paystubs (best for “current monthly”)
- Look for year-to-date earnings and how “gross” is calculated before deductions.
- Last 2 years of tax returns
- Helpful for annual averages, stability checks, or documenting non-wage income.
- Use W-2/1099 forms and any schedules supporting rental or other income.
- Recent bonus/commission statements
- If income varies, capture enough months to show a pattern (for example, 6–12 months).
- **Self-employment records (if any)
- Profit/loss information, business bank deposits, and a reasonable supportable view of expenses.
Checklist for income completeness:
Parenting time
- Proposed or existing parenting plan
- Calendar proof
- A simple month-by-month calendar showing overnights can help you convert to the tool’s format.
- Current practice
- If the schedule is informal, write down what actually happens (even if it differs from drafts).
Child information
- Birth certificates or other age proof
- School/daycare schedules (sometimes relevant when childcare costs come into play)
- Medical/insurance statements
- Premium amounts and who pays them.
Child-related expenses (only if your DocketMath run includes them)
- Childcare receipts or statements
- Health insurance premium invoices
- Medical bills (especially if unusually high or well-documented)
Run it

Suggested workflow (fast and accurate)
- Enter income inputs first
- Alimony and child support both depend on the “income picture,” so getting this right early reduces rework.
- Set child and parenting-time inputs next
- Parenting time is a major driver of child support output.
- **Add insurance and childcare/medical costs (if the tool includes them)
- These can change the final amounts even when income is the same.
- Review output ranges and sensitivity
- If DocketMath shows different outputs for different parenting time or expense inputs, rerun using your best-known documentation.
How outputs typically change when inputs change
While every case is different, these patterns are common when you adjust inputs:
| Input you change | What usually happens in the result |
|---|---|
| One parent’s gross monthly income increases | That parent’s support responsibility often increases (and the other parent’s decreases) |
| Parenting time shifts toward one parent (more overnights) | Child support may change because the shared-care factor changes |
| Add documented health insurance costs | Child support can adjust to reflect those costs if included in the tool’s calculation |
| Add (or remove) work-related childcare | Child support may increase if verified costs increase |
| Replace estimates with verified paystub numbers | Output may move materially—especially when overtime/bonus patterns are involved |
Warning: Parenting-time inputs can create major differences. If you’re not sure, run a “best guess” scenario and a conservative alternative so you can compare outcomes.
