Most online tools provide a rough range, but TBI claims in California depend on details that calculators can’t reliably capture—especially when the injury happens in a place with seasonal traffic, mixed witness reliability, or delayed reporting.
Instead of treating a calculator like a destination, use it like a checklist:
- What medical records exist right now (ER visit, follow-up neurology, therapy)?
- What functional limits can be documented (work restrictions, driving limits, cognitive changes)?
- What evidence ties the mechanism of injury to your symptoms?
A lawyer’s job is to evaluate the actual proof and how the other side is likely to value it in negotiation.
