How much will the iphone 6s cost on contract?

Can someone please estimate the cost of an iPhone 6s 16GB which will come out in september? I have at&t by the way if it helps.

The exact same price the iPhone 6 cost when it came out, so like 200$. But DO NOT get the 16gb model, you will regret it in the first 3 months, get atleast the 64gb model for 300$

AT&T no longer does contracts for phones, so you would be on the Next plan. You could check http://store.apple.com/...com/iphone & check the prices the 6 go for now as far as that goes & it should be the same prices for the 6s
