What you'll be doing is getting an upgrade where you'll renew for another 2 years. I think you might be eligible for one. Go to your local verizon dealer and they can check your account to see exactly what you're authorized for.
Verizon has a new every 2 program. Every twenty months you can get a new phone with a discount of $50. You can get a new phone every year if your the primary phone at a discount. ( Or so I have been told)
