One way to estimate it. I've seen this number range downward to $1 million.

"Smoke hoods should be on every airplane around the world" says Mary Schiavo, the former Inspector General of the U.S. Department of Transportation turned aviation-safety advocate. Her view is that the issue of evacuation time is merely a smokescreen for a cost/benefit analysis. "The government figures X amount of people are going to die and their lives are worth $2.7 million, and since the industry says it costs $127 million to do this … I am almost embarrassed as a former government official to explain how it works, but what it takes is a loss of life in dollar value equal to the cost of the equipment." The sad fact, according to Schiavo, is that it will take a catastrophic air disaster to change the FAA’s policy on smoke hoods for passengers."
