Most calculators are built to approximate outcomes using broad assumptions (like wages, injury type, and disability). That can be useful if you’re trying to understand the categories of benefits involved.
However, workers’ compensation in Illinois doesn’t reward “generic math.” Two people with the same diagnosis can end up with very different results depending on:
- How the injury was reported and whether the timeline is consistent
- Medical support for work causation and ongoing need for care
- Functional limitations (what you can and can’t do) and how clearly they’re written
- Whether your claim includes dispute issues (for example, the insurer questioning whether the condition is work-related)
In practice, your claim file often matters more than any calculator result.
