Many people start with a calculator because it feels like there should be a formula. In practice, insurers in Ohio usually evaluate TBI cases by looking for credible, consistent evidence:
- What the medical providers diagnosed (and how soon)
- Whether symptoms were documented over time (not just at the ER visit)
- How the injury affected function—focus, driving safety, work performance, household tasks
- Whether the accident facts support the mechanism of injury
If you’re building your case in Marietta after a head injury, the “range” from an online tool can be a starting point, but it can’t replace the way a claim is valued when liability is disputed or when the defense argues the symptoms are unrelated.
