A calculator typically estimates settlement value using limited inputs—such as whether you went to the ER, the length of treatment, and the presence of ongoing symptoms. That can be useful when you’re trying to plan ahead.
However, Illinois TBI cases turn on proof. Insurance companies evaluate whether your symptoms are consistent over time, whether your treatment was medically necessary, and whether the accident explains the injury—not just whether you report head trauma.
In practice, two people with “similar” concussions can have very different outcomes depending on:
- how quickly they sought medical care after the incident
- whether clinicians documented functional limitations (focus, memory, sleep, mood)
- whether work restrictions were supported by records
- what evidence exists about how the crash or fall happened
