All those folks on American Idol may have invested an awful lot to get there, according to this informative Bankrate slideshow about the costs of being on American Idol.

The cash outlay starts early, with some people flying to tryouts in other cities --- and having to trek there again if they get called back.

And let's not forget to mention the cost of abandoning any employment or other responsibilities (such as covering the rent) while you're chasing your dream.

You might find yourself subsidizing the weekly wardrobe budget to create the look of a star, according to Bankrate.
