Nutanix NCI Pro vs Cozystack at default assumptions
| Scenario | Nutanix NCI Pro 5-yr TCO | Cozystack 5-yr TCO* | Savings | Cozystack unit cost | Payback |
|---|---|---|---|---|---|
| SMB — 50 VMs | $287,314 | $141,606 | $145,709 (51%) | $47 / VM / mo | month 6 |
| Mid-size — 200 VMs | $729,445 | $342,915 | $386,530 (53%) | $29 / VM / mo | month 1 |
| Enterprise — 1,000 VMs | $3,143,668 | $1,514,562 | $1,629,106 (52%) | $25 / VM / mo | month 1 |
* Cozystack total includes the one-time migration from Nutanix NCI Pro (a fixed setup plus a marginal $/VM — owner estimate, Ænix field data). Estimates only — not a quote.
Break-even
Cozystack becomes cheaper than Nutanix NCI Pro when Nutanix NCI Pro $/core/yr exceeds $35 (current: $150) — it already does at the current value. One-time migration costs pay back in month 1.
Quote sensitivity: Nutanix NCI Pro 5-year total ranges from $460,645 at $70/core/yr to $2,409,445 at $650/core/yr.
Key facts
- Nutanix NCI Pro licensing: $650/core/yr list, ~$150/core/yr typical negotiated (street enterprise $70–130 pre-volume-discount; default midpoint-conservative $150 (§5.2/v1.1 #13); as of 2026-Q3).
- Contract term default: 36 months (avg contract 3.1 yr (research/02 §2)).
When to choose Nutanix NCI Pro
- Hard vendor-ecosystem dependencies (ISV certifications, existing tooling and runbooks) that outweigh the cost delta.
How this is calculated
Three cost articles — software (licenses + vendor support), one-time migration and personnel. Hardware and facilities are identical on both sides and excluded; an internal sizing chain (CPU oversubscription 3:1, RAM target 85%, per-platform storage replication, N+1 HA headroom) only produces the node/core/socket counters that licenses bill against. Renewal uplifts apply only after a real renewal event inside the horizon. Default pricing basis is realized (typical negotiated) — conservative against our own headline. Every default carries a source, date and source nature; owner estimates (migration setup and $/VM, personnel days) are labeled as Ænix field data.

Frequently asked questions
How much does Nutanix NCI Pro cost for 200 VMs over 5 years?
At default assumptions (EU region, typical negotiated prices, Q3 2026) the model puts Nutanix NCI Pro at $729,445 over 5 years across the three cost articles: software (licenses + vendor support), migration (one-time, target platform only) and personnel (a days-per-month staffing model).
Is Cozystack cheaper than Nutanix NCI Pro?
At 50 VMs: Cozystack is $145,709 cheaper (51%). At 200 VMs: Cozystack is $386,530 cheaper (53%). At 1000 VMs: Cozystack is $1,629,106 cheaper (52%). Cozystack becomes cheaper than Nutanix NCI Pro when Nutanix NCI Pro $/core/yr exceeds $35 (current: $150) — it already does at the current value.
What does migration from Nutanix NCI Pro to Cozystack cost?
For 200 VMs the model estimates $36,000 one-time: $8,000 of fixed setup — discovery, standing up the target, cutover design, runbook — plus 200 × $140/VM marginal (owner estimate — Ænix field data: 50 VMs ≈ $15K total). Most of a small migration is the setup, which is why cost does not scale with the estate. Professional services or training can be added via the "migration extras" input (default $0). One-time migration costs pay back in month 1.
What is included in the estimate — and what is not?
Exactly three articles: software (licenses + vendor support), one-time migration and personnel. Hardware and facilities are identical on both sides and excluded; backup, guest-OS licensing, DR/second site, GPU and security tooling are excluded uniformly. Full formulas and every source are on the methodology page.
Why is the Nutanix result shown as a range?
Nutanix pricing is quote-driven: reported street prices span roughly $70–650/core/yr. The calculator treats the realized price as a slider (default $150) and always reports quote sensitivity — the 5-year total at both ends of the range — rather than a single false-precision number.
Is Cozystack ready for regulated industries compared to Nutanix?
The model lists compliance and operational gaps for both sides with version and checked-date, and the HCL-driven hardware refresh risk for Nutanix reuse scenarios is a separate toggle. Turn on "Regulated industry" to float compliance notes to the top.
