Most calculators are built to model a “typical” injury scenario. Real Wilmette claims can diverge quickly because the details matter:
- Wage calculation can be more complicated than it looks (especially when pay includes overtime patterns or variable hours tied to seasonal work).
- Causation is frequently the dispute point—particularly with injuries that develop over time (back pain, repetitive stress, aggravation of a preexisting condition).
- Medical stabilization drives negotiation timing. If your condition isn’t stable yet, insurers may offer based on incomplete information.
- Functional limits matter more than diagnoses alone. Two people with the same diagnosis may have very different restrictions depending on work tasks.
So while a calculator might give you a rough starting range, it usually can’t account for what an adjuster, employer, and medical provider will focus on in Illinois.
