From the Customer Agreement | Verizon Wireless
"If you cancel a line of Service, or if we cancel it for good cause, during its contract term, you'll have to pay an early termination fee. If your contract term results from your purchase of an advanced device on or after November 14, 2014, your early termination fee will be $350, which will decline by $10 per month upon completion of months 7–17, by $20 per month upon completion of months 18–22, and by $60 upon completion of month 23 and will be $0 upon completion of your contract term. For other contract terms entered into on or after November 14, 2014, your early termination fee will be $175, which will decline by $5 per month upon completion of months 7–17, $10 per month upon completion of months 18–22, $30 upon completion of month 23 and will be $0 upon completion of your contract term. If your contract results from your purchase of an advanced device prior to November 14, 2014, your early termination fee will be $350 minus $10 for each full month of your contract term that you complete. For other contract terms entered into prior to November 14, 2014, your early termination fee will be $175 minus $5 for each full month of your contract term that you complete. Cancellations will become effective on the last day of that month's billing cycle, and you are responsible for all charges incurred until then."

Is the line you want to drop under contract? If not then no there's no cost unless you have a Device Payment on that line...if you close it then the balance of that device will be due in full.
The line is under a 2 year agreement but there's not a device payment plan
