How much will an iPhone 5s cost at Verizon?

Ok, I need some help, a lot of it haha. It's time to get a new phone, and I want to get the iPhone 5s, but here's the thing(s). One, I have the iPhone 4 with the unlimited data plan, yea I had it for a while. Two, I know I can trade it in for something. So what am I looking at price wise, because I know I need to get a data plan and all that now.

How Much Does an iPhone Cost at Verizon? Ok I'll answer it for you.

Here's the breakdown of the total iPhone price over a new or upgrade-eligible two-year AT&T, Sprint, or Verizon contract (not including overages, tax, or additional charges).
I made a column explain everything up here >>

To keep your unlimited data you will have to pay full price:
iPhone 5S with no contract/upgrade:
16GB - $649
32GB - $749
64GB - $849

It's cheaper with an upgrade, but you loose your unlimited data:
iPhone 5S with a 2 year contract/upgrade:
16 GB - $199
32 GB - $299
64 GB - $399

How much do you pay a month
