The Device AMP licensing system has two complementary tools. While both tools work toward the goal of simplifying Device AMP renewal management, they serve different purposes and are typically used at different stages of the licensing process:
Device AMP License Calculator – Used before purchasing licenses to determine how many Device AMP seats are required to align eligible devices to a common expiration date. It's important to differentiate this particular tool, is about forecasting, planning and purchasing smartly. This is what this article is about.
Device AMP Allocation Tool – Used after licenses have been purchased or redeemed to assign Device AMP coverage to devices using either Full-Seat Allocation or Shared (Pro-Rated) Allocation. We have a separate article for this.
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 allocate licenses. Instead, it recommends the number of licenses required based on your current environment. 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.
Before using the Device AMP License Calculator:
The calculator page will display your current Device AMP licensing information.
When the calculator opens, it automatically evaluates your registered devices and displays a summary of your current licensing status.
The information displayed includes:
This information is used to determine how many additional licenses may be required to reach a common renewal date.
The table displayed below the calculator lists every eligible device included in the calculation.
For each device you can view:
This allows administrators to verify which devices are contributing to the licensing calculation.
Select the desired Device AMP expiration date using the drop-down calendar.
For example: December 31, 2026
This represents the renewal date you would like all eligible devices to share after additional licensing is purchased and allocated.

After selecting the desired expiration date, click Calculate.
The calculator evaluates:
The system then calculates the minimum number of whole one-year Device AMP licenses required to reach, or slightly exceed, the selected expiration date

After the calculation completes, the Store will display:

⚠️Use caution! Deregistering a device will remove it from being listed active in your Management Portal account, and any remaining licensing associated to such device will be lost. This process is not reversible! The Device AMP License Calculator only determines how many licenses should be purchased.
After completing your purchase:
For detailed instructions, refer to: 📗Device AMP License Allocation Guide
To obtain the most accurate calculation:
Device AMP licenses are sold as whole one-year seats. Since fractional licenses cannot be purchased, the calculator recommends the nearest whole-license quantity that reaches or slightly exceeds the requested date.
No. The calculator only estimates the number of Device AMP licenses required. Purchasing licenses is a separate step.
No. License allocation is performed later from the My Licenses section using the Device AMP Allocation Tool.
The calculation is based on your current device inventory and licensing status. Registering new devices, deregistering existing devices, or changes to current Device AMP expiration dates will affect future calculations.
