How much does an iPhone 5 16gb cost?

I'm going to buy an iPhone 5 but how much does it cost with a contract with Sprint, Verizon, At&t?
On the Apple website, iPhone 5 16gb locked is 199$, but i don't understand, how long i have to pay 199$?
Eventually how much will i pay the iPhone?

200 upfront plus the first month bill which depends on your contract somewhere from 275 to 325 you will pay for the phone and activation and such

You can buy it in the near future, Come on!

When you sign a contract with a cell phone company you pay just the 199 once when you get the phone on a standard contract. Unless you go with the newer plan with AT&T or tmobile when you pay nothing up front and pay monthly installment over 20 months. Which is more expensive in the long run than way.
