A calculator can be a helpful starting point—especially if it prompts you to gather details about treatment, symptoms, and work impacts. But insurance adjusters don’t settle cases based on a model. In California, your value usually rises or falls on what can be supported:
- Medical causation (how the accident links to the brain injury and ongoing symptoms)
- Consistency over time (symptoms, treatment, and functional limits documented—not just remembered)
- Credible damages evidence (past bills, wage loss, and documented future needs)
That means two people with similar diagnoses may receive very different outcomes depending on record quality and how the defense tries to dispute causation.
