COBRA laws do not set the price. Usually, an employer will charge you whatever their cost for insurance is so that will vary greatly. If you were paying 50% of the cost then it will be twice as much. If your employer was paying more of the cost for insurance then Cobra would be less.
Years ago I was working for a company that went under and was self insured. The day the company filed there was no insurance and they were totally bankrupt...no cobra or otherwise so the law does not guarantee coverage in all situations. Many states have insurance pools for uninsurable people like us but that is also very, very expensive in most cases and usually has big deductibles.
Just another example of why we need universal health care that is not tied to an employer and is affordable and cannot exclude someone who is sick. There are so many still unemployed or employed as consultants with good pay but no benefits.
The irony of health insurance is that insurers only want to insure healthy people and will not insure sick people except under certain circumstances. If the Affordable Healthcare Law is knocked down by the Supreme Court the protections that went into place this year could disappear.
