I may need to extend my current timeline...

Which seems reasonable, given that he was an "eccentric billionaire playboy."

Batman is the .01%

Cheap by comparison to Iron Man, whose gear costs $1.6 billion: http://mashable.com/2012/07/30/iron-man-cost/

600mil to rebuild the manor?... Will Alfred with his $150k salary do all the work?

Alfred will manage the project but he better get a decent bonus for doing so.

Given that 85% of the figure is in the Wayne Manor, I consider the final total to be inaccurate.

In the second movie, he fights as batman after Wayne manor is burned down. So Wayne manor is not necessary to be batman; his underground lab seen in TDKR and TDK couldn't cost more than a few million dollars.

Also the $600,000 price tag seems exorbitant. Advanced laboratory complexes and buildings with significant underground components that measure as much as 250,000 square feet that I know of cost anywhere from $100,000,000 to $250,000,000.

Why would Bruce spend $500,000 on firearms training? And another $500,000 on pilot training? Commercial pilots licenses for both fixed and rotary-wing each cost less than $100,000. He dropped out of Princeton and as a tinkerer-hacker wouldn't need a degree to have the skills necessary to be a proficient programmer (which, as far as I know, is the only engineering skill in the movies he is shown to use. Other maker skills seem to be more machining/carpentry.)

That being said,some of the other components seem realistic, such as the Kevlar gear and the Tumblr. The DOD/armed forces regularly invest billions in prototype gear that never comes to market. The premise of Nolan's batman films that Bruce uses military-esque technology seems plausible. A functonal cape and a grappling hook that works too conveniently in use appear to be the most unrealistic. And of course the Bat.

Clearly you've thought about this a lot, David. :)

I wonder what $500k in firearms training and $500k in pilot training would buy me.

For a few minutes, at least. :) I like the info graphic; it's insightful. The $600,000,000 number immediately grabbed my attention so I made a mental note to return to this thread to discuss.

$500,000 in firearms seems like a random number-- especially considereing he only uses "firearms" in his vehicles. It's not "that hard" to shoot a rocket. Another good way to think about it is -- how many hours does it take to become proficient at something? If an instructor + materials cost $500/hr (a la plane/helicopter) ... well, it takes like 120 hours to get a commercial pilots license. And I can't imagine someone needing 1,000 hours of firearm training to do what Bruce Wayne does. :)

Also, I looked into getting pilots license a few months ago.

The person might be citing government/military costs -- as you know, those numbers are much more expensive. Defense contractors -- like the fictional Wayne Enterprises -- can get away with charging exorbitant prices; since, apparently, contracts are awarded on favoritism and other non-business factors.
