While there's no easy answer, the time it takes will depend on factors such as the type of accident, the severity of injuries, the amount of insurance involved, the at-fault party, the length of treatment and any liens that may be involved.

Because the answer to this questions depend on the specific circumstances associated with your situation, there's no online "calculator" that's going to give you a full-proof answer.
