How much is the total cost of iPhone 5s?

So my birthday is coming up soon and i'm going to get an iphone 5s, i want to get it from either sprint or a&t. For both companies the phone will cost $199.99 with two year contract, how does that work? And on both companies the at&t next (also sprint easy pay) says its $0 down and i pay $32/month( $27 for sprint)How does that work? How much do i pay monthly on the 2 year contract? How much total do i pay for either plan? Which do you recommend?

AT&T next you shouldn't really bother with (It's usually used for upgrading purposes, not for buying a new phone, and it costs more than just paying the $199.99)

I don't know about Sprint, but for AT&T, you'd pay:
1. The $199.99 (Plus tax) for the phone
2. A one time activation fee (Typically somewhere around $30 I believe)
3. Monthly plan would vary, but would hover around $80-$100/mo depending on what features you get (mainly, how much data you want)

I think 200 plus data package fee

$99 on 2 year contract right now through Verizon, best deal I've seen yet and its 5S.
