Akro would be interesting to see what the FAA's CBA figure was when they did the analysis..
It took me 3 minutes to find. I timed it.

note:
The mid to low-end GA aircraft owner faces a marginal business case based on current equipage
costs. Based on the benefits of FIS–B and Situational Awareness applications, the payback
period is 6 to 12 years for ADS–B In equipage. It will cost aircraft operators an estimated
$6,000 to $12,000 per aircraft for a panel mount display, including installation costs, to
implement ADS–B In (this does not include ADS–B Out); the business case would be marginal
because hull values of many existing GA aircraft may not justify this additional investment.

If you spent time going back through docket numbers I'm sure there will be more detail. Unlike AsA, the FAA is quite transparent.
