Most online tools are built to approximate parts of a claim—often including wage replacement, medical-related costs, and impairment-related components.
In practice, a calculator’s estimate can drift from reality when:
- your injury is partly gradual (common with repetitive lifting or job-site strain)
- your pay includes overtime, shift differentials, or irregular hours that don’t match the tool’s assumptions
- your medical records don’t line up cleanly on causation (whether symptoms are tied to the specific work event or duties)
- there’s a dispute about temporary vs. permanent restrictions
So think of the calculator as a starting point—not a promise of what you’ll be offered.
