[Batman] What's Batman's annual budget?

Or his annual expenses?

It's going to depend on the Batman media, since the scope of Batman's operations can vary pretty wildly.

If we go by the modern comics though, Jezebel Jet, who presided over a small country in Africa, estimated that Batman's budget was greater than her country's own defense budget just from looking around the Batcave.

So its probably in some increments of 100s of millions of dollars.
