Calculator Inputs
Formula Used
Impairment award: impairment value percent ÷ 100 × 100 × Oregon state average weekly wage.
Work disability award: modified work disability percent ÷ 100 × 150 × capped worker weekly wage.
Wage cap helper: capped wage equals the worker wage limited between 50% and 133% of the state average weekly wage.
Total estimate: impairment award + work disability award - prior award offsets - advances - selected deductions.
Combined impairment helper: A combined value is built as A + B × (1 - A), using decimal values in sequence.

Understanding Oregon PPD Estimates
Oregon permanent partial disability, often called PPD, relates to permanent loss after an accepted work injury becomes medically stationary. This calculator is built for planning. It is not a final claim decision. A closure notice, medical findings, and Oregon rating rules still control the award.
Why Impairment Matters
Impairment measures permanent loss of use or function. It may involve reduced motion, strength loss, sensory loss, surgery, amputation, or another rated medical finding. In many claims, impairment is the starting value. The calculator lets you enter one impairment value or combine several values before the award is estimated.
How Work Disability Changes the Result
Work disability may apply when the worker is not released to regular work or has not returned to the job held at injury. It reflects impairment plus vocational issues. Age, education, skills, and adaptability can affect that value. Because the official rating process is detailed, this tool lets you enter a direct modified value or build a simple planning value from helper factors.
Why Wages and Caps Are Included
Oregon formulas use the state average weekly wage for impairment. Work disability uses the worker’s weekly wage, with limits tied to the state average weekly wage. This page includes cap settings so users can test careful scenarios. It also shows the capped wage separately, which makes the estimate easier to audit.
Using the Estimate Safely
Use the result as a checklist, not a promise. Confirm the state average weekly wage for the closure date. Check whether the worker returned to regular work. Review any prior awards, offsets, or advances. Save the CSV or PDF for discussion with an adjuster, advocate, or attorney.
Best Practices
Enter values from reliable claim documents. Avoid guessing medical percentages. Keep notes about each assumption. If a notice of closure uses different numbers, compare each field line by line. Small input changes can create large award differences. That is why the table, formula notes, and export tools are included together.
Record Keeping Tips
Store the medical report, claim closure, wage proof, and calculation export together. Add dates for every document. Clear records help identify missing findings, wrong wage entries, duplicate offsets, and assumptions that need review before appeal deadline passes.
FAQs
What is an Oregon PPD calculator?
It is a planning tool that estimates permanent partial disability amounts from impairment, wage, work disability, and offset inputs. It does not replace an official claim closure or legal review.
What does impairment mean?
Impairment means permanent loss of use or function. It may come from medical findings such as reduced motion, strength loss, sensory change, surgery, or amputation.
When is work disability included?
Work disability may be included when the worker is not released to regular work or has not returned to the regular job held at injury.
Why does the state average weekly wage matter?
The impairment formula uses the state average weekly wage. Work disability wage limits are also tied to that wage, so the correct period matters.
Can I combine several impairment values?
Yes. Enter values separated by commas or line breaks. The helper combines them sequentially, then uses the combined value in the award estimate.
What are offsets?
Offsets are amounts subtracted from the gross estimate. They may include prior permanent awards, advances, credits, or other deductions shown in claim documents.
Is the PDF a legal report?
No. The PDF is only a saved copy of the entered assumptions and estimated results. Official decisions depend on claim records and applicable rules.
Should I use the default wage values?
No. Replace defaults with current, verified figures. Use the correct Oregon state average weekly wage and the worker’s documented weekly wage.
