Many calculators work by taking the information you provide—such as the type of injury, length of recovery, and out-of-pocket costs—and then applying simplified assumptions to produce a potential range.
That can be useful if you’re trying to understand categories of damages, like:
- past medical expenses
- future medical needs
- lost income or reduced earning capacity
- non-economic harms (pain, loss of function, emotional impact)
However, these tools often miss the details that matter most in California malpractice cases—especially the kind of evidence that tends to show up in review after the fact, such as:
- whether follow-up care was appropriate
- whether imaging/labs were interpreted correctly and acted on in time
- how the chart describes symptoms before and after the alleged error
- whether a known risk was warned about and documented
In other words: a calculator can help you organize questions. It usually can’t replace an attorney’s evidence-based evaluation.
