Example Data Table
| Scenario | Model | Hosts | CPUs / Host | Cores / CPU | Term | Price Input | Estimated Grand Total |
|---|---|---|---|---|---|---|---|
| Mid-size production cluster | Per Core Subscription | 4 | 2 | 20 | 3 years | USD 95 per core / year | USD 65,842.74 |
| Legacy renewal check | Legacy / Per CPU Style | 6 | 2 | 24 | 2 years | USD 2,400 per CPU / year | Depends on growth, support, and tax |
| Transition planning | Hybrid Custom Estimate | 8 | 2 | 32 | 3 years | Mix core and CPU pricing | Useful for migration budget modeling |
Formula Used
max(physical cores per CPU, minimum licensable cores per CPU)
hosts × ceil((CPUs per host × licensable cores per CPU) × (1 + growth buffer %))
hosts × ceil((CPUs per host × ceil(cores per CPU ÷ cores covered per CPU license)) × (1 + growth buffer %))
Per Core model: buffered core units × price per core per year
Per CPU model: buffered CPU units × price per CPU license per year
Hybrid model: both values added together
annual base license cost + (annual base license cost × support uplift %)
((annual recurring total × contract years) + one-time costs − discount) + tax
This calculator assumes a uniform hardware profile across hosts. For mixed clusters, run separate scenarios for each host group and add the totals.
How to Use This Calculator
- Enter the number of hosts, CPUs per host, and physical cores per CPU.
- Choose the licensing model that matches your quote or internal estimate.
- Adjust the minimum licensable cores or legacy coverage values if your contract differs.
- Type the quoted annual core price, CPU price, or both for hybrid planning.
- Add support uplift, contract years, growth buffer, tax, discounts, and one-time project costs.
- Submit the form to view the result above the calculator.
- Review the summary table, per-host breakdown, and chart.
- Export the output as CSV or PDF for budgeting, approvals, or procurement reviews.
FAQs
1) What does this calculator estimate?
It estimates annual and multi-year licensing cost for VMware environments using host counts, CPU counts, core counts, support uplifts, taxes, discounts, and one-time project expenses.
2) Can I use it for subscription and older processor-style models?
Yes. You can switch between a core-based subscription estimate, a processor-style estimate, or a hybrid planning mode for migration and comparison scenarios.
3) Why is there a minimum licensable cores field?
Some licensing structures count a minimum number of cores per CPU even when the hardware has fewer. Keeping this field editable makes the calculator flexible for different contracts.
4) What is the growth buffer used for?
The growth buffer adds planning headroom before price is calculated. It helps model future expansion, spare capacity, or near-term infrastructure growth without building a separate worksheet.
5) Does the result include support and services?
Yes. Annual support uplift is calculated from the base license estimate, and one-time training, migration, and other services are added to the term total.
6) Can I calculate per-host or per-VM cost?
Yes. The result includes annual and term cost per host, and if you enter an estimated VM count, it also shows recurring and term cost per VM.
7) Is this suitable for mixed hardware clusters?
It works best for uniform hosts. For mixed clusters, calculate each host group separately, then combine the outputs to get a more accurate estate-level estimate.
8) Are the exported CSV and PDF files useful for procurement reviews?
Yes. The exports capture the summary metrics, host breakdown, and generated date, making them suitable for budgeting packs, approval workflows, and commercial comparisons.
