Most calculators work by taking a few inputs—like injury severity, medical costs, and lost wages—and producing a rough range. That can help you understand which categories often drive value.
But a Herrin case can swing significantly based on:
- How fault is documented after a crash (especially when the initial story changes)
- Whether treatment matches the injury timeline (gaps can become a negotiation target)
- Whether the insurance company disputes causation—claiming symptoms weren’t caused by the crash
- How policy coverage is structured (limits and who is insured)
In other words, a calculator can’t verify your medical records, evaluate credibility, or predict how an adjuster will frame liability.
