How much money does it really cost to program an app?

I've used some online calculators to calculate the final cost of creating an app. The result was a bunch of obnoxious, over-inflated prices that were all over $300,000 just to design 13-14 screens for an iPhone.

I find this price absurd… I have no programming knowledge and I'm in need of a person who can develop an slightly complex app.

I designed a nice looking website for about $200 myself… I cut on many unnecessary costs. I looked up the price estimations of making a website and they were all pretty obnoxious too, considering the fact I only spent $200 when some of these websites claim a website costs $30,000 to create.
Could the same be done with an app?
Added (1). I appreciate your sarcasm. As you see, I have no programming skill.
