Device AMP License Calculator Guide

Overview

The Device AMP licensing system has two complementary tools. Both aim to simplify Device AMP renewal management, but they serve different purposes at different stages of the licensing process.
Device AMP License Calculator — Determines how many Device AMP seats are required before purchase to align eligible devices to a common expiration date. This tool focuses on forecasting, planning, and purchasing.
Device AMP Allocation Tool — Used after licenses have been purchased or redeemed to assign Device AMP coverage using Full-Seat Allocation or Shared (Pro-Rated) Allocation. See the 📗Device AMP License Allocation Guide for details.

About the Device AMP License Calculator:

The Device AMP License Calculator is a planning tool available within the NComputing Store that helps determine how many Device AMP licenses should be purchased to align all eligible devices to a common expiration date.

Rather than manually calculating renewals for individual devices, the calculator analyzes your existing Device AMP licensing and estimates the number of additional one-year Device AMP licenses required to achieve a desired fleet-wide expiration date.

The calculator does not purchase or allocate licenses automatically. It recommends a quantity based on your current environment and lets you proceed directly to purchase from the same page. After purchasing and redeeming the recommended licenses, they can be applied using the Device AMP Allocation Tool available in the My Licenses section of the Management Portal. See the 📗Device AMP License Allocation Guide for details. 


Before You Begin

Before using the Device AMP License Calculator:

  • Devices must already be registered in the NComputing Management Portal.
  • Devices should remain connected and online so the Management Portal can display accurate and current licensing information.
  • Only devices compatible with Device AMP licensing benefits are included in the calculation.

Accessing the Device AMP License Calculator

  1. Log in to the NComputing Management Portal.
  2. From the Home menu, click Purchase Licenses and Services.

  1. In the left-hand navigation tabs, click on Device AMP License Calculator.

The calculator opens and automatically displays a list of active, connected devices.


Understanding the Dashboard

When the calculator loads, it displays four summary cards across the top
  1. Eligible Devices — The total number of devices included in the calculation.
  2. Earliest Expiration — The earliest current Device AMP expiration date across all eligible devices.
  3. Latest Expiration — The latest current Device AMP expiration date across all eligible devices.
  4. License SKU — The one-year Device AMP license part number NC-AMP-RXRDP-1A is the base the calculator will provide results from.


Alert
Note: One-Year License Design
The Device AMP License Calculator is designed around one-year Device AMP licenses. Multi-year subscriptions, such as three-year or five-year licenses, cannot be prorated because they already include discounted pricing and cannot be divided into smaller licensing values.
If you plan to use this calculator or the Shared (prorated) Allocation tool, the only compatible licensing will be one-year Device AMP licensing. 

Understanding the Device List

The table displayed below the calculator lists every eligible device included in the calculation.

For each device you can view:

  • Serial Number
  • Registration Date
  • Current Device AMP Expiration Date

The list can be sorted by expiration date. Devices that are near or past their current expiration may be highlighted in red so they can be identified at a glance.

Alert
Important: Device Pagination Affects Visibility
A common source of confusion involves the device table pagination control located in the lower-right corner of the page. By default, only 10 devices are displayed.
Available options include: 10, 50, 100, 500, and 1000 to be displayed at once in the page. If your environment contains more than 10 devices, you should increase the page size before reviewing selections.



Why This Matters
Suppose 13 devices are eligible, but only 10 devices are currently visible in the webpage. Since you cannot see beyond the 10 selected, you may unintentionally compute licensing to only a portion of the whole environment.
Increasing the visibility of units in the webpage, will display your complete device inventory and allow you to verify which devices are included in the calculation.

Step 1: Choose Target Expiration Date

Select the future expiration date you want all eligible devices to reach from the Desired future expiration date drop-down, then click Calculate.

For example: December 31, 2026


This is the renewal date that you would like for all eligible devices to share after additional licensing is purchased and allocated.

How this works: The calculator estimates the total licensing time required to extend all devices from their current expiration dates to the selected target date. It then rounds up to determine how many new one-year Device AMP licenses you should purchase.

Step 2: Calculation Result

After you click Calculate, the calculator displays:
  1. Target expiration date — The closest achievable expiration date based on 1 year licensing.
  2. Eligible devices included — The number of devices covered by the calculation.
  3. Required one-year Device AMP licenses — The recommended quantity to purchase
NotesWhy is the target date different of what I chose? Because Device AMP licenses are sold as whole seats, the calculated expiration date may extend slightly beyond the date originally selected. This behavior is expected, since fractional licenses cannot be purchased. Therefore, the calculator recommends the nearest whole-license quantity capable of reaching the requested date.

A summary line confirms the recommendation, like the example below: “Based on the selected target expiration date, you should purchase approximately 20 one-year Device AMP license(s) (SKU: NC-AMP-RXRDP-1A).” Click PURCHASE to go directly to checkout for the recommended quantity.

Here you will be able to enter your credit card details and finalize your transaction. The transfer of licenses to your Management Portal account will be automatic. 

What Happens Next?

After completing your purchase you will use our second automated tool:
  1. Redeem the Device AMP license key, if applicable.
  2. Open My Licenses.
  3. Select Allocate.
  4. Use the Device AMP Allocation Tool to apply the licenses with either Full-Seat Allocation or Shared Allocation (Pro-Rated) and bring eligible devices to the same expiration date.
For complete post-purchase instructions, see the 📗Device AMP License Allocation Guide

Remove Devices You No Longer Use

Only active devices should remain registered in the Management Portal. Devices that have been retired, replaced, or permanently removed from service should be deregistered before calculating Device AMP requirements. Removing unused devices reduces the required license quantity and helps avoid unnecessary renewal costs.
Tip: Use the Deregister function from the My Devices section of the Management Portal to remove inactive devices.
WarningWarning: Deregistering a device removes it from your Management Portal account, and any remaining licensing associated with that device is lost. This process is not reversible.

Best Practices

To obtain the most accurate calculation:

  • Ensure all devices are currently reporting to the Management Portal.
  • Remove devices that are no longer in use before calculating.
  • Select a realistic renewal date that aligns with your maintenance schedule.
  • Remember that your purchase of Device AMP licenses are, and must be, the one-year part number, as this is the only allowed type of license in the Device AMP License Allocation Tool.
  • Remember that calculations are based on your current environment. Registering or deregistering devices afterward may change the allocation results.
Frequently Asked Questions. Click here to expand.
Why does the calculated expiration date not exactly match the date I selected?
Device AMP licenses are sold as whole one-year seats. Because fractional licenses cannot be purchased, the calculator recommends the nearest whole-license quantity that reaches or slightly exceeds the requested date.

Does the calculator purchase licenses automatically?
The calculator estimates the required quantity and lets you proceed to purchase from the same page, but purchasing remains a separate, deliberate step.

Does the calculator allocate licenses?
License allocation happens after purchase from My Licenses, using the Device AMP Allocation Tool.

Why did my required license count change?
Calculations reflect your current device inventory and licensing status. Registering new devices, deregistering existing devices, or changes to Device AMP expiration dates can affect future calculations.
 

Conclusion

The Device AMP License Calculator helps you forecast and purchase the right number of Device AMP licenses to bring eligible devices to a common expiration date. After purchase, use the Device AMP Allocation Tool to apply the licenses to your devices.
