How this calculator works
The AI Cost Per Resolved Support Ticket Calculator works out what it actually costs to close one support ticket when an AI assistant handles the front line. You enter your monthly ticket volume, the deflection rate (the share the AI resolves without a human), the input and output tokens each ticket consumes, your model's input and output prices per million tokens, and the human cost of each escalated ticket. It then blends the AI token cost on deflected tickets with the human cost on the remainder to show a true, all-in cost per resolved ticket rather than a raw per-message API price.
The key trade-off to watch is deflection rate versus quality. A higher deflection rate spreads cheap token costs across more tickets and lowers the average, but pushing it too far can produce weak answers that customers reopen or escalate anyway—quietly adding the full human cost back on top of what you already spent in tokens. Use the calculator to find the point where a modest, reliable deflection rate beats an aggressive one, and re-check it whenever token prices, ticket mix, or model choice change.
Frequently asked questions
How do I calculate the cost per resolved ticket with AI?
Multiply input and output tokens per ticket by the model price to get the AI cost per ticket. The AI resolves a share of tickets (the deflection rate); the rest escalate to a human at their loaded cost. Total cost equals AI cost on every ticket plus human cost on the escalated share. Divide by total tickets for the blended cost per resolved ticket, and compare it to an all-human baseline.
Why is deflection rate the number that matters most?
AI tokens are cheap — often cents per ticket — so the real driver of savings is how many tickets the AI actually closes without a human. A high deflection rate spreads a fixed human cost over fewer escalations; a low one means you pay for AI on every ticket and still pay a human on most of them, which can cost more than staying fully human.
