How much will Apple charge me to replace a cracked screen?

I have an iphone 4 and there's a a big spider web crack in the top right corner. Basically I want some straightforward answers. Does Apple Care cover this? How much would the deductible be? Can I just go to the Genius Bar in the Apple Store and get it replaced for free? I'vde been getting a million different answers and I'm stressing. Please someone who actually knows what they're talking about, Give me some answers.

You can call the Apple Store and ask them.
