Windows Server 2025 Standard costs $1,176 and Windows Server 2025 Datacenter costs $6,771 per 16-core pack at Microsoft’s suggested price, retrieved 2026-10-11 ^S01. Windows Server 2025 Standard covers 2 VMs per full licensing of the host, and Datacenter covers unlimited VMs ^S01. At those list prices Datacenter is cheaper than stacked Standard from 11 VMs per host, at every host size tested ^derived. Windows Server 2025 pay-as-you-go through Azure Arc costs $33.58 per core per month at Microsoft’s price (retrieved 2026-10-11) ^S01.

This guide gives the prices, the licensing rules and the support dates behind that comparison. All prices are USD list prices and may vary by country ^S01.

Price your own hosts

To price your own hosts, open the Windows Server licensing calculator. It turns hosts, sockets, cores and VMs into the license cost of Standard, Datacenter and pay-as-you-go, with the arithmetic shown.

Open the Windows Server licensing calculator. Enter hosts, sockets per host, physical cores per socket and VMs per host. License physical cores only. The defaults are 2 hosts, 2 sockets, 16 cores per socket and 12 VMs per host.
Enter the virtual cores per VM (default 4) and pick a term of 1, 3 or 5 years. Perpetual licenses cost the same at every term ^S07. Pay-as-you-go grows with the term.
Read the cheapest option and expand “Arithmetic” on any row to see each step. Optional inputs: tick the Software Assurance box to see per-VM core counts, and enter a CAL count and your own CAL price.

For a host with 2 sockets of 16 cores and 12 VMs, Windows Server 2025 Standard costs $14,112 and Datacenter costs $13,542 ^derived. Standard is 6 full licensings of 32 cores at $2,352 each ^derived. The share link keeps your inputs. The embed code is at the foot of this page.

To compare Windows Server with VMware or Proxmox VE, use the hypervisor licensing calculator. For a wider platform list, see VMware alternatives compared.

Windows Server license cost: Standard vs Datacenter prices

Both editions of Windows Server 2025 are priced per 16-core pack at Microsoft’s suggested price, retrieved 2026-10-11 ^S01. A core license costs the pack price divided by 16 ^derived. Microsoft publishes no 2-core pack price. It states that eight 2-packs and one 16-pack are priced the same ^S02.

	Windows Server 2025 Standard	Windows Server 2025 Datacenter	Source
Price per 16-core pack	$1,176	$6,771	^S01
Price per core (pack price / 16)	$73.50	$423.19	^derived
VMs per full licensing of the host	2	unlimited	^S01
Hyper-V hosts per license	1	1	^S01

One Windows Server 2025 Datacenter pack costs 5.76 Standard packs: 6,771 / 1,176 ^derived. Microsoft’s pricing page names no price level, so these are suggested prices ^S01. The Open License program was retired on 2021-12-31 ^S02, so these figures are suggested prices, not an Open price list.

Dated comparison: the archived 2023-06-01 pricing page for Windows Server 2022 shows Standard at $1,069 and Datacenter at $6,155 per 16-core pack ^S14. These 2022 figures are dated. Against 2025, both rise by 10 percent, computed as (new - old) / old ^derived. Microsoft states no change percentage.

Windows Server licensing rules: cores, minimums and packs

License every physical core on the server. Microsoft defines a physical core as a core in a physical processor ^S02. The minimum is 8 core licenses per physical processor and 16 per server, and the greater result applies ^S02. Core licenses are sold in 2-packs and 16-packs ^S02, and above the minimum they are added in steps of 2 ^S03.

Server	Core licenses required	Source
1 or 2 processors, 2 cores each	16	^S02
Four processors, 2 cores each	32	^S02
1 processor, 10 cores	16	^S02
2 processors, 10 cores each	20	^S02
Four processors, 10 cores each	40	^S02

Standard allows 2 VMs per full licensing of the host. For each further 2 VMs, the server must be relicensed for the same number of core licenses ^S02. This is called stacking. Datacenter needs no stacking ^S02.

Per-VM licensing is a third route. It needs 8 core licenses per VM and 16 per customer, gives rights to one virtual OS environment per license, and needs subscription licenses or active Software Assurance ^S02. Microsoft added it in 2022-10 ^S02. The calculator shows the core count and never prices it, because Microsoft publishes no Software Assurance price ^S01.

Windows Server Standard vs Datacenter: 11 VMs per host

Take a host with 2 sockets of 16 cores. Windows Server 2025 Standard costs $2,352 per full licensing and Datacenter costs $13,542 ^derived. At 10 VMs Standard costs $11,760. At 11 VMs it costs $14,112, above Datacenter ^derived.

Why the result is the same at every host size: both editions scale with licensed cores. Per 16 cores, 5 full licensings of Standard (10 VMs) cost 5 x $1,176 = $5,880, below Datacenter at $6,771. Six full licensings (11 VMs) cost $7,056, above it ^derived.

Windows Server Standard vs Datacenter: licence cost by VM count, 2 x 16 core hostUSD, list prices retrieved 2026-10-11. Break-even at 11 VMs per host.

2 sockets x 16 cores = 32 core licences per host. Standard covers 2 VMs per full licensing.
More VMs need the host relicensed for each extra set of two VMs (stacking). Datacenter has no VM limit.
Perpetual Microsoft suggested MSRP per 16-core pack, USD, retrieved 2026-10-11: Standard 1,176, Datacenter 6,771.
Core licences are priced pro rata from the 16-pack (Microsoft says eight 2-packs and one 16-pack cost the same).
Excluded: CALs, Software Assurance, volume discounts, failover headroom. Prices vary by country.

All figures below are per host, in USD, and derived from the S01 prices and the S02 stacking rule ^derived.

Physical cores per host (2 sockets)	Standard, 1 full licensing (2 VMs)	Datacenter	Standard at 10 VMs	Standard at 11 VMs	Datacenter cheaper from
16	1,176	6,771	5,880	7,056	11 VMs
24	1,764	10,156.50	8,820	10,584	11 VMs

64	4,704	27,084	23,520	28,224	11 VMs

Prices for 24 cores rest on the S02 statement that 2-packs and 16-packs are priced the same ^S02. The break-even does not depend on it. The figures assume VMs are spread evenly and exclude CALs, Software Assurance and volume discounts.

Windows Server pay-as-you-go through Azure Arc

Windows Server 2025 pay-as-you-go costs $33.58 per CPU core per month ^S01, or $0.046 per core per hour ^S09, both retrieved 2026-10-11. That is $402.96 per core per year (33.58 x 12) ^derived. The price is the same for Standard and Datacenter ^S07. There is no minimum core count per machine or per subscription ^S08. It needs Windows Server 2025 ^S07. A new enrolment gets a seven day trial ^S08.

Pay-as-you-go gives no rights for extra VMs. Each VM needs its own license, whatever the host ^S07. It includes base CAL rights, but RDS CALs are still required ^S03.

Take one machine of 32 cores. Pay-as-you-go and Datacenter compare as follows ^derived.

32 cores	1 year	3 years
Pay-as-you-go, one instance	$12,894.72	$38,684.16
Datacenter, unlimited VMs, perpetual ^S07	$13,542	$13,542

Over 3 years pay-as-you-go costs 2.86 times Datacenter ^derived. Its cumulative cost passes Standard ($2,352) in month 3 and Datacenter in month 13 ^derived. The comparison prices one instance, while Datacenter covers unlimited VMs on the host.

Windows Server CAL pricing: what Microsoft publishes

Microsoft lists no stand-alone price for Windows Server User CALs or Device CALs, and none for the External Connector ^S01. The calculator therefore takes your own CAL price. Remote Desktop Services CALs are a separate product that the Microsoft Store sells ^S04. Microsoft Store US retail price, RDS CALs only, not a volume licensing price, changes without notice: $264 per RDS User CAL or RDS Device CAL, retrieved 2026-10-11 ^S04. It is not a price for Windows Server User or Device CALs, and the calculator does not use it. Microsoft lists no Software Assurance price ^S01, and Software Assurance is sold only through Volume Licensing ^S15. This page derives no per-CAL price.

What the sources state:

Both editions require a CAL for every user or device accessing a server ^S01.
A CAL is a User CAL or a Device CAL ^S02.
A CAL covers the same or an earlier version of the server software ^S02.
A Remote Desktop Services CAL is required in addition to the base CAL ^S02.
Pay-as-you-go needs no base CAL, but RDS CALs are still required ^S03.

The calculator adds CAL cost only when you enter both a count and your own price per CAL. It adds the cost to Standard and Datacenter, and not to pay-as-you-go.

Windows Server support dates, 2016 to 2025

Microsoft gives each end date as a timestamp at the end of that day, US Pacific time. This page shows the US Pacific calendar date, so the 2022 mainstream support end date is 2026-10-13. Depending on your time zone, Microsoft’s own page may show the day after. Phase is as of the data check, 2026-10-22. Windows Server 2022 mainstream support ended on 2026-10-13, so the release is in extended support.

What the result means

Each row is the cost of that option on your cluster, before tax. Standard and Datacenter are perpetual licenses, so their 3-year figure equals their 1-year figure ^S07. Pay-as-you-go is a monthly meter, so its figure grows with the term ^S01.

Excluded unless you enter them: CALs, Software Assurance, External Connector, volume and negotiated discounts, OEM pricing, taxes, other currencies and Windows Server 2025 Essentials. Microsoft’s pricing page lists only Standard and Datacenter, with no Essentials price ^S01. The Essentials edition is sold through OEMs only ^S02.

Methodology summary

Every price and rule comes from Microsoft pages retrieved on 2026-10-11. The calculator reads them from the published dataset, version 1. Money is computed from the unrounded pack price and rounded half up to the cent once, on the final figure. Licensed cores per host are the greater of 16 and the sum over processors of the greater of 8 and the cores in that processor, rounded up to a multiple of 2. Standard for v VMs needs v / 2 full licensings, rounded up. Two flagged third-party entries are excluded from every figure. Full detail is on the methodology page.

The last data check of this page is 2026-10-22, so the cut-off for the label “dated” is 2024-10-22, which is 24 months earlier. Only the archived 2022 prices ^S14 are dated. Lifecycle dates are never labelled dated. A support date that passes is a refresh trigger. The page, table and chart are redrawn at the next check. That is why Windows Server 2022 now shows extended support.

Known limits:

Prices are suggested prices in USD. Quotes vary by channel and country ^S01.
Standard assumes an even VM spread and no failover headroom. A cluster sized to survive a host failure licenses for the worst-case host.
All hosts in a scenario are identical. Mixed clusters need one run per host type.
The rules come from Microsoft’s licensing guidance page ^S02 and cover Windows Server 2025. The lifecycle table covers 2016 to 2025.
Pay-as-you-go prices VMs only and needs Windows Server 2025 ^S07.
