How much is iphone 5s if i can't upgrade until 1 more year?

My contract is 2 years and 1year is left, can i just get the 5s or do i have to pay more?

If you want an upgrade it will still cost you the full amount as if you are just purchasing the hardware. I believe it is about $650 or so for a new iPhone without a new plan. The 2 year contract will only make you pay about a third of it at about $230. If you really want the new iphone you should just go for it and get it! But if you don't care about it that much and you just think it looks pretty cool you should probably just wait, I mean it's only 1 year.

You'll have to pay full price.

iPhone 5S with a 2 year contract/upgrade:
16 GB - $199
32 GB - $299
64 GB - $399
