How much would the iPhone 6 cost if I just bought it without upgrading or anything?

I've been thinking of buying a new phone and getting rid of my 4 year old one that's pretty much broken. My brother told me to go to the apple store and just buy the iphone 6 and it would just cost $199. But then my friend told me that it would be a lot more expensive since I can't really upgrade. But I just wanna know how much it would actually cost without upgrading.

$599/649 depending on the carrier you are on.
