How to Use the Device AMP License Expiration Calculator

How to Use the Device AMP License Expiration Calculator

Introduction

The Device AMP License Expiration Calculator helps you figure out how many Device AMP licenses to buy so that all your devices share one expiration date. This is especially useful when you're planning for renewals or simplifying license management across many devices.


Where to Find the Calculator

  1. Go to NComputing.com and login with your user credentials and click the Management Portal tab.
  2. In the Management Portal Home Page, click on the Purchase Licenses & Services icon
  3. In the left-hand menu, click Device AMP License Calculator.

How It Works

When you open the calculator, you’ll see:
  1. A summary of your device AMP licensing status.
  2. The number of devices currently eligible for licensing.
  3. A reminder that license allocation is pro-rated, and calculated expiration dates may vary slightly depending on future device changes.

In the provided summary, observe in the disclosures in the upper part of the window, which reflects the system’s methodology for determining the total number of devices subject to device AMP licensing.

Additionally, please be advised that once licenses are acquired, you will gain access to the Pro-Rated Allocation feature. Furthermore, the expiration date calculated by this utility may differ from the actual allocation due to potential changes in devices, such as the addition of new devices.


Using the Calculator

  1. Choose your desired expiration date.
    Example: You want all devices to be licensed through December 31, 2026. 

  2. Click the CALCULATE button.
    The system will figure out how many licenses you need to purchase to get as close as possible to your chosen date — using whole licenses only (no fractions).

    For instance, if 134.73 licenses would get you to Dec 31, 2026, the system might recommend purchasing 137 licenses, which brings the expiration slightly past that date (e.g., January 3, 2027).


    Notice that if the calculated date differs from the desired date because the system doesn’t allow fractions of a license. To achieve an expiration date of December 31, 2026, a purchase of 134.73 licenses of NC-AMP-RXRDP-1A is necessary. The system determines the minimum number of whole licenses required to meet or exceed the desired date.

  3. After clicking CALCULATE, a purchase interface will appear with the recommended license quantity.

    When the the  button is clicked, the purchase UI with the calculated number of licenses will display, allowing you to proceed with the purchase.

    Important note: Before completing your purchase, you'll need to check a box confirming you understand that all sales are final — no refunds or exchanges.


Allocating the Purchased Licenses

Once your licenses are purchased, you can allocate them right away — either to all devices or to a specific group of devices using the new Device Group feature in the Management Portal.

Option 1: Standard Allocation (All Devices)

  1. Click My Licenses icon

  2. Locate your newly purchased licenses and click on ALLOCATE
  3. Assign licenses to the eligible devices using the Pro-Rated Allocation tool.

Option 2: Device Group–Based Allocation (Targeted Subsets)

You can now allocate licenses just to a specific set of devices using the new Device Groups feature in the Management Portal:

Steps to apply pro-rated Device AMP via Device Groups:

  1. Select a Device Group. If you have created a group, you should be able to see the device groups available at the left of the window.
    Choose the group you’ve created that includes the devices you want to license.
  2. Choose Devices. Select all devices in that group — or just a subset of them.
  3. Apply Allocation. Click Apply Now to assign the pro-rated Device AMP coverage.

This method is ideal if you're rolling out coverage in phases or managing different licensing timelines across departments or regions.
