Turn It Down: Cost by Conversation Length Simulator

Focus on three categories: cost deflection, quality, and speed. On cost, track handle time reduction and the percentage of tickets fully resolved without human escalation—this is your clearest line to dollar savings. On quality, watch CSAT and first-contact resolution rates, since a chatbot that frustrates customers creates downstream churn costs that easily exceed the savings. On speed, measure median time-to-resolution; customers value quick answers more than human ones, and this is often where LLMs outperform scripted IVRs. Set a 90-day baseline before any LLM goes live.

Assume your current blended cost per ticket is $12, handling 10,000 tickets monthly—that's $1.44M annually. A well-tuned LLM chatbot typically deflects 40–60% of volume at roughly $0.08–0.20 per deflected ticket in API costs. At 50% deflection, that's 5,000 tickets at $1.00 each in API costs versus $60,000 in agent costs—a monthly saving of roughly $59,000, or $708K annually. Against a $200–400K implementation and year-one tuning cost, you're looking at a 12–18 month payback. The variable that kills these projections is containment rate: if your chatbot escalates 70% instead of 50%, the economics invert almost immediately.

Three costs routinely get sandbagged: data preparation, evaluation infrastructure, and organizational change. Data is the largest surprise—cleaning, labeling, and structuring historical tickets for retrieval or fine-tuning typically runs 2–3x what teams budget. Evaluation is next: without a rigorous way to measure response quality at scale, you won't catch regressions before customers do, and building that infrastructure costs real engineering time. The third is change management—contact center agents whose queue shrinks by half need new roles or they leave, and attrition costs rarely appear in AI project budgets. Together these add 60–80% to the headline implementation number.
