How much do AI voice agents cost? A 2026 per-minute breakdown

"How much does an AI voice agent cost?" has no single answer, because vendors price three different ways and most advertised rates leave things out. Here's how to read them and budget accurately.

The three pricing models

• Per-minute, usage-based — you pay for talk time. The most transparent, and the easiest to forecast.
• Subscription plans — a fixed bucket of minutes per month; predictable, but often expensive per minute once you add provider fees.
• Outcome-based — you pay only for a successful resolution. Used by some enterprise platforms; typically sales-led with high minimums.

What makes up a per-minute cost

A voice agent runs three models plus telephony: speech-to-text, a language model, and text-to-speech, over a phone line. Some platforms quote only their orchestration layer (around $0.05/min) and add STT, LLM, TTS and telephony on top — so the real all-in cost commonly lands anywhere from $0.13 to $0.33/min once configured.

What you should actually compare

Ask for the all-in per-minute cost before you launch, broken down by component. Callaro shows exactly that: an entry-level stack from $0.06/min, component by component, with no seat fees. For the full picture of how agents work end to end, see the complete guide to AI voice agents.
