Benefit amounts vary from state to state, but it's fairly typical for states to provide two-thirds of your previous wages in benefits, subject to a weekly cap. In addition, workers' comp benefits can cover the cost of your medical care. A number of factors determine exactly how much you'll receive in workers' comp, and for how long. They include:
whether and for how long you're unable to work
the severity of your illness or injury, and
the rules in your state.
As you'd expect, temporary injuries are typically worth less than permanent ones. Likewise, if your injuries have left you "totally disabled" (that is, completely unable to work), you'll receive more than if you're only "partially disabled" (still able to perform a less demanding job).
