How to Justify an HPC Investment? In-House Feasibility Guide
7 August, 2026
Strategy
The hardest part of an HPC investment feasibility study is not the technical details. Choosing the right server, the right network technology, and the right storage architecture — these are engineering problems with known solutions. The real challenge is presenting this investment to senior management, procurement committees, or the board of directors.
“Why buy physical servers when we have the cloud?”
“Wouldn’t it be better to spend this money on software?”
“There are more urgent needs waiting at the university.”
Each of these objections can be answered with a feasibility report that clearly demonstrates HPC cost analysis and strategic value. This guide walks through how to structure an in-house HPC feasibility study step by step, and how to present it to management.
When Does HPC Investment Make Sense? Decision Tree
Not every organization needs HPC — and not every organization that needs it should buy. Key questions to answer before starting HPC budget planning:
How long do your current workloads take? If a single simulation takes 8 hours and you run 10 per month, this is not an HPC problem — perhaps a more powerful workstation will do. But if you run 500 simulations per month and each takes 24 hours, HPC becomes unavoidable.
What are your queue wait times? If you use shared resources and your jobs regularly wait in queues, the cost of lost time often exceeds the cost of a cluster.
Are your software license costs optimized? Software like ANSYS, MATLAB, and Gaussian is typically licensed per core. Idle licenses on scattered workstations can be used at full capacity on a centralized cluster.
Decision tree summary:
| Situation | Recommendation |
|---|---|
| < 50 intensive jobs/month, < 4 hrs/job | Workstation sufficient |
| 50-200 intensive jobs/month, acceptable queue time | Cloud HPC or rental model |
| > 200 intensive jobs/month, queue time critical | Build your own cluster |
| Seasonal/fluctuating workload | Hybrid: base cluster + cloud burst |

Total Cost of Ownership (TCO) Framework
The true cost of a high-performance computing investment goes beyond the server price tag. TCO must be evaluated over a 3-5 year window.
| Cost Item | Share of TCO | Description |
|---|---|---|
| Hardware (servers, network, storage) | 40-50% | One-time capital expenditure |
| Software licenses (annual) | 15-25% | ANSYS, SLURM, compilers, libraries |
| Data center (power, cooling, space) | 10-15% | Annual operating expense |
| Personnel (sysadmin, support) | 15-20% | Annual; minimum 1 FTE |
| Maintenance and support contracts | 5-10% | Annual hardware/software maintenance |
Sample TCO — 32-node mid-scale cluster:
| Year | Hardware | Licenses | DC | Personnel | Maintenance | Annual Total |
|---|---|---|---|---|---|---|
| 1 | $450,000 | $60,000 | $40,000 | $50,000 | $25,000 | $625,000 |
| 2 | — | $60,000 | $40,000 | $50,000 | $25,000 | $175,000 |
| 3 | — | $65,000 | $42,000 | $52,000 | $25,000 | $184,000 |
| 3-Year TCO | $984,000 |

ROI Calculation: Measuring Investment Returns
TCO shows cost; ROI shows value. When you propose a “$1 million server” to the board, the first question will be “what do we gain?” Here are concrete ROI items:
1. Time Savings (Easiest to Measure)
A CFD simulation takes 8 hours on a workstation but 45 minutes on a cluster. At $30/hour engineer salary:
- Workstation: 8h x $30 = $240/simulation
- Cluster: 0.75h x $30 = $22.50/simulation
- Savings: $217.50/simulation
For a team running 200 simulations/month, this means $522,000/year in engineer time savings alone. After subtracting the 3-year TCO of $984,000, net savings over 3 years is $582,000.
2. Research Output and Competitive Advantage
Faster simulations = more iterations = better optimized designs. This translates to technical superiority in defense contracts, increased academic publications, or faster patent applications.
3. License Optimization
Idle ANSYS licenses on scattered workstations can achieve 85-95% utilization on a centralized cluster. If 10 ANSYS CFD licenses cost $200,000/year, canceling 2 licenses saves $40,000/year.
Feasibility Report Template
A feasibility report for management should include:
| Section | Audience | Content |
|---|---|---|
| Executive Summary (1 page) | Senior management, board | All decision information: current state, proposed solution, cost, payback period |
| Current State Analysis | IT director, department heads | Current computing infrastructure, bottlenecks, queue times, user dissatisfaction |
| Needs Analysis | All stakeholders | Which department uses which software, how often, at what scale? 3-year growth projection |
| Alternatives Comparison | Procurement, CFO | Buy vs lease vs cloud: TCO comparison of 3 models |
| Proposed Solution & Specs | IT team, procurement | Hardware list, architecture diagram, software stack, installation timeline |
| Cost & Budget | CFO, procurement | 3-year TCO, annual cash flow, payment plan |
| Risks & Mitigation | Board, risk committee | Supply chain risk, personnel risk, technology obsolescence; plan B for each |
| Recommendation | Senior management | Clear recommendation: “We request purchase approval” or “Proceed with rental model” |
This template can be customized for your organization through our HPC Consulting service.
Alternative Models: Rental, Cloud, and Hybrid Approaches
| Model | Advantage | Disadvantage | Best For |
|---|---|---|---|
| Purchase (CapEx) | Lowest 5-year TCO, full control | High upfront cost, tech obsolescence risk | Predictable, continuous workload |
| Rental (OpEx) | Low upfront cost, budget flexibility, 3-year refresh cycles | More expensive long-term | Tight budget, unpredictable workload |
| Cloud (Pay-as-you-go) | Zero upfront, infinite scalability | Expensive at scale, data egress costs | Fluctuating workload, PoC phase |
| Hybrid | Base load on-prem, peaks in cloud | Complex management, data transfer costs | Growing organizations |

Frequently Asked Questions
How long does a feasibility study take?
2-4 weeks depending on organization size and data accessibility. Mevasis accelerates this by streamlining needs analysis and technical specification phases.
Can we get consulting only and buy hardware ourselves?
Yes. Mevasis offers HPC Consulting independent of hardware sales. We can prepare vendor-independent technical specifications or deliver turnkey solutions.
Can we start small and grow over time?
Absolutely. An 8-16 node cluster can be expanded as needs grow. The rental model is ideal for gradual scaling. See Capacity Expansion for details.
Are there tax incentives or government grants for HPC investment?
Organizations with R&D center certification can classify HPC hardware under R&D deductions. TUBITAK and KOSGEB also offer technology infrastructure support programs. Consult your financial advisor.
