## Case Examples

Here are a few case-examples of what billing would look like on Vapi for different voice pipeline configurations.

  pricing.

### Call Center (Inbound Phone)

A customer is looking to use Vapi to assist their call center staff taking phone calls inbound:

<Steps>
  <Step title="Scenario">
    <div>
      "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.
    </div>

    <div>
      Expected monthly usage will be 10,000 calls, with an average of 2 minutes per call. For Voice,
      PlayHT will suit our needs.
    </div>

    <div>What is my pricing breakdown?"</div>
  </Step>

  <Step title="Providers">
    The providers used will determine per-minute cost. The following providers will be involved:

    <div>**Deepgram:** transcription</div>
    <div>**Custom Model:** model</div>
    <div>**PlayHT:** voice</div>
    <div>**Twilio:** telephony (receiving inbound phone calls)</div>

    <br />

    <Frame caption="The customer will be using a custom model & taking inbound phone calls.">
      <img src="https://mintlify.s3-us-west-1.amazonaws.com/vapi-bephrem-pricing/static/images/learn/billing/custom-model-inbound-phone-example.png" />
    </Frame>

    <br />
  </Step>

  <Step title="Cost Breakdown">
    We will break down the costs of each piece of the voice pipeline, then later multiply by call volume:

    <div>**Deepgram:** ≈ \$0.01/min</div>
    <div>**Custom Model:** ≈ \$0.04/min (vague assumption, can vary widely)</div>
    <div>**PlayHT:** ≈ \$0.07/min</div>
    <div>**Twilio:** ≈ \$0.02/min (inbound, toll-free number) (see Twilio [phone call pricing](https://www.twilio.com/en-us/voice/pricing))</div>
    <div>**Vapi:** \$0.05/min</div>

    <Tip>Our [estimating costs](/learn/billing/estimating-costs) guide can help you determine these values.</Tip>
  </Step>

  <Step title="Final Estimate">
    Call Minutes / Month: 10,000 calls x 2 min/call = **20,000 call minutes**

    <div>**Transcription:** \$0.01/min x 20,000 = **\$200**</div>
    <div>**Custom Model:** \$0.04/min x 20,000 = **\$800**</div>
    <div>**Voice:** ≈ \$0.07/min x 20,000 = **\$1,400**</div>
    <div>**Telephony:** ≈ \$0.02/min x 20,000 = **\$400**</div>
    <div>**Vapi:** \$0.05/min x 20,000 = **\$1,000**</div>

    **Total**: **\$3,800**/mo
  </Step>
</Steps>

### Real Estate Lead Generation (Outbound Phone)

A customer doing real estate lead generation is looking to use Vapi to automate parts of their sales calling operation:

<Steps>
  <Step title="Scenario">
    "I have a company that does real estate lead generation, and would like to use Vapi voice
    assistants to automate parts of my sales process.

    Calls would average \~4 minutes, for Model I want to use GPT-4-turbo through your platform, and for Voice I will be using a ElevenLabs.

    I’d like a breakdown based on sending 1,000 outbound calls in one month."
  </Step>

  <Step title="Providers">
    <div>**Deepgram:** transcription</div>
    <div>**OpenAI (GPT-4 Turbo):** model</div>
    <div>**ElevenLabs:** voice</div>
    <div>**Vonage:** telephony (sending outbound phone calls)</div>

    <br />

    <Frame caption="The customer will be using GPT-4 & making outbound phone calls.">
      <img src="https://mintlify.s3-us-west-1.amazonaws.com/vapi-bephrem-pricing/static/images/learn/billing/outbound-phone-example.png" />
    </Frame>

    <br />
  </Step>

  <Step title="Cost Breakdown">
    <div>**Deepgram:** ≈ \$0.01/min</div>
    <div>**OpenAI (GPT-4 Turbo):** ≈ \$0.20/min</div>
    <div>**ElevenLabs:** ≈ \$0.04/min</div>
    <div>**Vonage:** ≈ \$0.01/min (outbound call) (see Vonage's [phone call pricing](https://www.vonage.com/communications-apis/voice/pricing))</div>
    <div>**Vapi:** \$0.05/min</div>

    <Tip>Our [estimating costs](/learn/billing/estimating-costs) guide can help you determine these values.</Tip>
  </Step>

  <Step title="Final Estimate">
    Call Minutes / Month: 1,000 calls x 4 min/call = **4,000 call minutes**

    <div>**Transcription:** \$0.01/min x 4,000 = **\$40**</div>
    <div>**Model:** \$0.20/min x 4,000 = **\$800**</div>
    <div>**Voice:** ≈ \$0.04/min x 4,000 = **\$160**</div>
    <div>**Telephony:** ≈ \$0.01/min x 4,000 = **\$40**</div>
    <div>**Vapi:** \$0.05/min x 4,000 = **\$200**</div>

    **Total**: **\$1,240**/mo

### Mock Intervieweing Application (Web)

A web engineer is looking to develop a website that helps job candidates practice for job interviews. They are looking to use Vapi for their virtual interviewers:

<Steps>
  <Step title="Scenario">
    "Hi, I'm looking to develop a web application for mock interviews. Users will be able to practice for a variety
    of job interviews with AI interviewers.

    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?"
  </Step>

  <Step title="Providers">
    <div>**Deepgram:** transcription</div>
    <div>**Custom Model:** model</div>
    <div>**PlayHT:** voice</div>

    <br />

    <Frame caption="The customer will be using a custom model & making web calls (no telephony will be involved).">
      <img src="https://mintlify.s3-us-west-1.amazonaws.com/vapi-bephrem-pricing/static/images/learn/billing/web-interviews-example.png" />
    </Frame>

    <br />
  </Step>

  <Step title="Cost Breakdown">
    <div>**Deepgram:** ≈ \$0.01/min</div>
    <div>**Custom Model:** ≈ \$0.10/min (vague assumption, can vary widely)</div>
    <div>**PlayHT:** ≈ \$0.07/min</div>
    <div>**Vapi:** \$0.05/min</div>

    <Tip>Our [estimating costs](/learn/billing/estimating-costs) guide can help you determine these values.</Tip>
  </Step>

  <Step title="Final Estimate">
    Call Minutes / Month: 1,000 calls x 30 min/call = **30,000 call minutes**

    <div>**Transcription:** \$0.01/min x 30,000 = **\$300**</div>
    <div>**Model:** \$0.10/min x 30,000 = **\$3,000**</div>
    <div>**Voice:** ≈ \$0.07/min x 30,000 = **\$2,100**</div>
    <div>**Vapi:** \$0.05/min x 30,000 = **\$1,500**</div>

    **Total**: **\$6,900**/mo
