ROI Calculator – AI Integration vs. Manual Processes
Is AI worth it for your business? Compare personnel costs and error costs with the investment in an AI-powered solution.
AI replaces repetitive cognitive tasks, reduces errors, and scales without additional personnel costs. Our ROI calculator shows when the investment in an AI solution pays for itself and how much you save over 5 years through reduced personnel costs and fewer errors.
The benefits of AI extend far beyond pure time savings: AI systems work consistently and without fatigue, drastically reducing error rates. With increasing work volume, an AI solution scales without additional staff – the marginal cost per processed case approaches zero. Furthermore, AI models improve over time through continuous feedback, so savings continue to grow with each month.

Why AI Investments Pay Off Quickly
Time Savings
AI processes documents, emails, and inquiries in seconds instead of hours. 200 hours of manual processing per month are reduced to 50 hours – at 75% automation level.
Error Reduction
AI systems work consistently and don't get tired. Typical error rates of 3-5% drop below 1% – less rework, fewer complaints, higher quality.
Scalability
Double the volume? No problem. AI scales without additional personnel costs. Running costs only increase minimally with volume.

Get Your Investment Funded
AI projects receive particularly strong funding: Programs like "KI in der Praxis" (AI in Practice), "go-digital", and state programs offer funding rates of up to 50%. The BAFA funding for business consulting can also be utilized when an AI strategy workshop is part of the project.
Frequently Asked Questions: AI Integration vs. Manual Processes
When is an AI investment worth it?
AI is especially worthwhile for: recurring cognitive tasks (document processing, customer inquiries, data analysis), high error costs from manual processing, processes with increasing volume, and tasks that need to be available 24/7. The break-even typically falls between 4-18 months.
What does a typical AI solution cost?
The investment varies significantly: Simple AI tools for specific tasks (e.g., document classification) from €20,000 excl. VAT. Medium AI projects (e.g., chatbot with knowledge base) €40,000-100,000 excl. VAT. Complex AI systems (e.g., predictive analytics) €100,000-300,000 excl. VAT. Ongoing costs are €200-2,000/month for hosting and API usage.
What are the ongoing costs of AI?
Ongoing costs include: API usage for AI models (e.g., OpenAI, Azure AI) €100-1,500/month depending on volume, hosting and infrastructure €100-500/month, monitoring and maintenance €200-500/month, occasional adjustments for new requirements. In total, typically €500-2,500/month – significantly less than the saved personnel costs.
How accurate are AI systems?
Modern AI systems achieve accuracy rates of 85-98% depending on the task. For structured data (e.g., invoices, forms), 95-98% is realistic. For unstructured text (e.g., emails, documents), typical values are 85-92%. Accuracy improves with training and feedback. We recommend a pilot phase to measure actual performance.
When does AI not make sense?
AI is not advisable for: very low volume (less than 20 h/month), extremely variable processes without patterns, tasks requiring human empathy (e.g., grief counseling), very low error costs, and processes that are already fully automated. In these cases, traditional automation or manual processing is often more cost-effective.
How does the ROI calculator work?
The calculator compares total costs over 5 years: Option A (without AI) = personnel costs + error costs, rising by the annual cost increase. Option B (with AI) = one-time investment + reduced personnel costs + reduced error costs + ongoing operating costs. Break-even is reached when Option B becomes cheaper. The calculator accounts for automation level and error reduction through AI.
How accurately does an AI solution work?
AI models achieve typical accuracy rates of 85–98% for trained tasks. For structured data like invoices or forms, 95–98% is realistic. Accuracy continuously improves through feedback and retrained models. For critical decisions, we also implement confidence scoring, so uncertain cases are forwarded for manual review.
What happens with unexpected inputs?
Professional AI systems use confidence scoring and a human-in-the-loop approach. This means: the AI evaluates its own certainty with every decision. If the confidence score falls below a defined threshold, the case is automatically forwarded to an employee for manual review. This ensures no erroneous decisions slip through.
Do I need AI expertise on my team?
No, we handle the development, training, and operation of the AI solution. Your team uses the AI through a user-friendly interface or integrated into existing systems – without any AI knowledge required. On request, we train your employees in using the solution and offer a managed service for ongoing operation and further development.
