Many online tools generate a number by applying assumptions about wages, treatment, and impairment. In California, those variables can shift significantly depending on the claim file.
Common reasons calculator results don’t match what happens in practice include:
- Wage details don’t reflect the way you actually earned money (overtime, variable hours, or pay changes).
- Your injury wasn’t documented early enough—even short delays can create gaps insurers try to use.
- Your medical record doesn’t line up with the story of the incident (for example, the work mechanism isn’t clearly connected to the diagnosis).
- Your restrictions matter more than the injury label—two people with the same diagnosis may have very different work limitations.
- The condition evolves—what looks minor early can become permanent after additional treatment.
In other words: calculators can help you think in ranges, but they rarely capture what California decision-makers focus on—especially when the claim involves disputed medical causation.
