# What a voice agent call costs, and how to keep it down

Per-minute pricing is simple to read but easy to misjudge. What goes into the cost of a call, and the levers that actually lower it.

-   Pricing
-   Operations

Every voice agent call uses several services at once: the phone line, speech-to-text, a language model and a voice. Vaakyo bundles them into one per-minute price for the default models, billed per second from prepaid credits, so you see one number per call. See [pricing](https://vaakyo.com/pricing) for the current rates and plans.

## What changes the cost of a call

-   **Length.** The biggest lever by far. A two-minute call costs about twice a one-minute call.
-   **Model choice.** Premium language models and some voices cost more per minute. The console shows the price of each choice before you pick it.
-   **Channel.** Browser calls don't use a phone line, so they cost less than phone calls.
-   **Retries and failures.** Failed calls aren't charged, but unanswered retries still use time in your campaign.

## Lower the cost per outcome, not just per minute

-   **Get to the point.** A greeting that says who is calling and why in the first sentence shortens calls and reduces hang-ups.
-   **Short replies.** One or two sentences per turn keeps calls brisk.
-   **End cleanly.** Agents that don't know when to end keep talking. Add a closing step to the prompt.
-   **Use the default models unless you need more.** Upgrade one agent at a time and compare the outcome rate, not just the transcript quality.
-   **Call at the right time.** Better reach rates mean fewer wasted retries.

## Plans for steady volume

If you call every week, a monthly plan with included minutes and a lower rate per extra minute is usually cheaper than pay-as-you-go. Check your average monthly minutes in the console's usage page against the plans before switching.

## Keep an eye on it

Every call shows its cost, and reports show spend by agent and campaign. A sudden rise in average call length is often the first sign that something in the conversation changed.
