How to calculate your chatbot ROI
The basic formula to justify the investment:
ROI = (Savings generated - Chatbot cost) / Chatbot cost x 100
Step 1: Calculate deflected tickets
If your team receives 1,000 tickets/month and the chatbot resolves 40% automatically:
- Deflected tickets: 400/month
Step 2: Cost per human ticket
The average cost to resolve a ticket with a human agent is $15 - $25 (salary + tools + overhead).
- Monthly savings: 400 x $20 = $8,000/month
Step 3: Compare with investment
- Citai Pro cost: $99/month
- Net savings: $8,000 - $99 = $7,901/month
- ROI: 7,980%
Even with more conservative deflection rates (20%), ROI is positive from month one.
Pricing by industry: which plan do you need?

- Typical ROI: Very high due to ticket deflection volume
SaaS / Technology
- Volume: Medium (technical questions, documentation, troubleshooting)
- Recommended plan: Starter ($29/month) or Pro depending on volume
- Typical ROI: High — technical docs index perfectly in RAG
Healthcare
- Volume: Low-Medium (appointments, schedules, general questions)
- Recommended plan: Free or Starter — FAQs cover most queries
