A calculator can offer a rough starting range, but it can’t account for the details that insurers in California focus on—especially for head injuries.
In practice, your settlement value usually turns less on the label (“concussion,” “mild TBI,” “brain injury”) and more on proof of:
- Symptom consistency from the day of injury onward (headaches, dizziness, memory problems, sleep disruption, mood changes)
- Functional impact—missed shifts, reduced productivity, restrictions, safety limits, and daily living changes
- Causation—how the mechanism of injury matches what clinicians documented
- Treatment continuity—whether you followed recommendations or can explain gaps
If the record is thin or the story doesn’t line up with medical notes, adjusters often push settlement offers downward—even when the injury is life-altering.
