Chatbot Deflection ROI
Calculate ROI of replacing human support tickets with LLM responses.
Tickets to Cost/Ticket = 625:1 (625 as decimal).
Chatbot Deflection
Avg human-handled ticket: $5–$15 (US). LLM-handled: $0.05–$0.20. Net savings × deflection rate = ROI. 5,000 tickets × $7 saved = $35k/mo.
Worked Example
5000 Tickets to 8 Cost/Ticket
- a
- 5000
- b
- 8
- Result
- 625:1 (625.00)
5000 / 8 = 625.00. Simplified: 625:1.

Frequently Asked Questions
How is the Chatbot Deflection ROI computed?
Tickets divided by Cost/Ticket, plus a simplified ratio (e.g., 4:3) using greatest common divisor. Both decimal and ratio forms are useful in different contexts: decimal for math, ratio form for comparisons or recipe scaling.
What does Tickets:Cost/Ticket mean?
It's a comparison: for every Cost/Ticket unit, you have a corresponding amount of Tickets. Useful when the absolute numbers matter less than the proportion (e.g., reading 8:1 LTV/CAC immediately tells you the unit economics are healthy without needing the dollar amounts).
Why simplify the ratio?
4:3 is more readable than 200:150. The simplified form (using greatest common divisor) preserves the proportion while making it easier to interpret. Common simplified ratios: 16:9 (widescreen), 4:3 (legacy displays), 3:1 (LTV:CAC for SaaS).
When is a ratio more useful than the absolute values?
Comparison across scales. A $1B company and a $1M company can both have a 3:1 LTV:CAC; the ratio reveals comparable unit economics regardless of scale. Use ratios for benchmarking; use absolute numbers for budgeting.
