How much is it to replace my water damaged iPhone 5c under warranty?

Words cannot describe the anger I'm feeling as I write this. I UNDERSTAND that Apple does not cover water damage I would just like to know how much it will be for me to replace it? I am still under warranty if that makes the situation less annoying. I have an upcoming appointment at the Genius Bar this coming Monday and would like to know beforehand (the accident happened on Saturday) please let me know ASAP.

Thanks.
