Can I trade in my iphone 5 for an iphone 5s?

How much would it cost to trade in my iphone 5 for an iphone 5s it's in good condition no cracks.

It depends on whether or not your carrier has a trade in plan. Better idea to sell it on craigslist or ebay. For instance verizon will give NO MORE than $200 if your lucky. You could get at least 300 on ebay.
