How much could you save?

How the Calculator Works

This ROI calculator compares the total cost of ownership (TCO) of cloud AI subscriptions against a WerkHub AI on-premise appliance over a 1 to 5 year period. It factors in your team size, estimated usage intensity, and the specific cloud AI service you currently use or are evaluating.

What We Compare

• Cloud subscription costs — per-user monthly fees for services like ChatGPT Business (approximately €25–30/user/month), Claude Team (€25/user/month), or Microsoft 365 Copilot (€30/user/month).
• On-premise appliance costs — one-time hardware investment (starting at €5,900 / from €2,950 with Digitalbonus), annual electricity (approximately €800–2,500 depending on tier), and optional support contract.
• Break-even point — the month at which cumulative cloud costs exceed the on-premise investment, typically between 12 and 18 months for teams of 50+ users.

Example Scenario

A company with 100 users paying €25 per user per month for a cloud AI subscription spends €30,000 annually, or €90,000 over three years. A WerkHub AI Business appliance (2× RTX PRO 6000 Blackwell, 192 GB GDDR7) costs €37,000 upfront (or €18,500 with Digitalbonus) plus approximately €3,500 per year in electricity and next-business-day support — totaling roughly €47,500 over three years. That represents savings of approximately €42,500 while gaining full data sovereignty and GDPR compliance by architecture.

All projections use Q2 2026 cloud AI pricing. Actual savings depend on your team size, usage patterns, and the specific cloud service you compare against. The calculator below lets you adjust these variables to match your specific situation.
