Windows Server License Calculator

How many core licenses does your server need, is Standard or Datacenter the better deal, and which CALs come on top? Answer three short questions – the calculator puts together the matching package from our range and explains every step.

  1. Your server
    Windows Server version

    Usually 1 or 2.

    Physical cores only; hyper-threading threads do not count. In Windows: Task Manager › Performance › CPU › “Cores”.

  2. Virtualization

    VMs on this host that run Windows Server. 0 if Windows Server runs directly on the hardware.

    Edition
  3. Access to the server

    Every person or device that accesses the server (sign-in, file sharing, printing, applications) needs a client access license (CAL). If you know both numbers, we choose the cheaper CAL type.

    Remote Desktop Services (RDS) require an RDS CAL per person or device in addition to the CAL.

    Leave empty if everyone works via Remote Desktop.
