Most online tools give a rough range, but in real TBI disputes the number is driven by proof and risk. Insurance adjusters and defense counsel typically look for three things:
- A credible link between the incident and the brain injury symptoms
- Documented functional impact (work, daily routines, cognition, sleep, mood)
- Objective support from medical records, testing, and consistent treatment
That’s why two people can enter the same “calculator” with similar initial symptoms and receive very different settlement offers—because one case is supported with stronger evidence than the other.
