Total Cost of Ownership for AI

The biggest trap in AI projects: underestimating the true costs. License fees are just the tip of the iceberg. Without knowing the TCO, your business case will fail.

The 5 Cost Blocks

1. Software & Licenses

• SaaS solutions: €500–50,000/month depending on provider and usage
• API costs: GPT-4o, Claude, Gemini — costs scale with usage (token-based)
• Specialized software: Industry-specific AI tools (e.g., Contract AI, Predictive Maintenance)

2. Infrastructure

• Cloud compute: GPU instances for training and inference
• Storage: Databases, data lakes, vector stores
• Network: Bandwidth for data transfer and API calls
• Security: Encryption, firewalls, compliance infrastructure

3. Personnel

The largest and often underestimated cost block:

4. Data Preparation

• Data cleansing: 30–50% of the total project budget
• Labeling: Manual annotation of training data
• Integration: Connecting to existing systems (ERP, CRM, DMS)

5. Hidden Costs

The costs nobody plans for:

• Change management: Training, communication, resistance management
• Opportunity costs: What could employees be doing instead?
• Iteration: First version rarely works — plan for 2–3 iterations
• Compliance: GDPR conformity, AI Act, documentation requirements
• Maintenance: Model drift requires regular retraining

TCO Rule of Thumb

Real TCO ≈ License costs × 3–5

If the software costs €50,000/year,
plan for €150,000–250,000/year total costs.

Tip: Create a TCO overview for 3 years. Many AI projects only become profitable from year 2 onwards.
