3-year cost calculator
Pre-filled for Microsoft Hyper-V → Harvester HCI. Adjust every figure with your own numbers.
Every figure here is an illustrative estimate, not a vendor quote. Defaults are editable starting points compiled from public information; real, binding pricing comes from the vendor or an authorized distributor. See our methodology.
How this is licensed: vSphere licenses the physical CPU cores of each host (16-core minimum per CPU), not VMs. Count total physical cores across hosts and set $/core to your subscription tier.
All figures are illustrative and fully editable — adjust the cost-per-core and migration inputs with your own numbers. Not guaranteed vendor pricing (defaults reviewed May 2026). For a binding quote, use the request form below to reach an authorized distributor or partner.
