Case Examples
Here are a few case-examples of what billing would look like on Vapi for different voice pipeline configurations.
A customer is looking to use Vapi to assist their call center staff taking phone calls inbound:
Scenario
“I want to use Vapi voice assistants to support my human customer service reps in a call center. However, I have a custom LLM I would prefer to use instead of the ones offered through the platform.
Expected monthly usage will be 10,000 calls, with an average of 2 minutes per call. For Voice, PlayHT will suit our needs.
Providers
The providers used will determine per-minute cost. The following providers will be involved:
The customer will be using a custom model & taking inbound phone calls.
Cost Breakdown
We will break down the costs of each piece of the voice pipeline, then later multiply by call volume:
Final Estimate
Call Minutes / Month: 10,000 calls x 2 min/call = 20,000 call minutes
Total: $3,800/mo
A customer doing real estate lead generation is looking to use Vapi to automate parts of their sales calling operation:

Interviews will be 30-minutes each (at max), for model I’ll be using a custom open-source model hosted with Baseten & for voice I’ll be using PlayHT.
How much would this cost me each month if I service 1,000 interviews per month?”
Providers
