The cost of being Batman

After bringing up in this thread the fact that the tech Batman uses is not in the realm of science fiction anymore I started thinking: just how expensive would all these toys be?

The calculation below is a result of this train of thought. It covers only the Batsuit and the usual gadgets not the Batmobile, Batwing or the Batcave.

Update: A few people have asked so I'll make this clear. All these are things you can buy right now or develop rather simply given a little financial backing. Most are off the shelf but some of them can't be bought by civilians without authorization.
The second thing I'd like to clear up is that I made these calculations myself. I'm not an economist I'm an engineer. I did it by searching through google for sources.

I'm sure I missed something so I can round it to 200000USD. Before you go to empty your bank account and become a superhero keep in mind that some of this stuff gets used every time he goes out. Armor probably needs to be replaced every week. That's 7000USD/week operating cost from the start. Batarangs, trackers, gas... all those are disposable and cost money. I estimate the operating costs must be around 10000USD/week not counting any Batmobile. Shredded that memory polymer cape? New one costs 40k!

On top of that some of this equipment must be bought by the thousand (like Alfred says in Batman Begins). Some of this equipment is restricted to military and law enforcement. If Waynetech wasn't a military contractor Batman wouldn't have access to some of this stuff.

In other words it's possible but even a milionare would have trouble supporting these costs on a regular basis. Strictly the realm of multi-bilionares.
