Most online calculators assume a “generic” work injury and a “generic” wage history. In real cases, the numbers depend on things like:
- Whether the injury is documented the same day it happened (or as soon as possible)
- How quickly treatment started after the incident
- Whether your job restrictions are consistent with what doctors say you can safely do
- Your wage base in Illinois (including how overtime/shift work is treated in your specific history)
- Whether symptoms are explained clearly in medical notes
In Marion, it’s common for workers to return to modified duty (or try to) while they’re still recovering. If that attempt is described inconsistently—or if restrictions aren’t documented—insurers may argue your condition isn’t as limiting as you report. That’s one reason a calculator range may feel “too low” or “too high.”
