## Full Transparency Pricing

Learn how **voice-to-voice interactions** are priced, including Convocore's platform fees, providers' costs, and concurrency limitations. We believe in complete transparency about what you're paying for.

***

## 💰 Platform Base Fee

Convocore charges a **platform fee of 3 cents per minute** (\$0.03/min) in addition to the provider's costs. This covers:

* Infrastructure and hosting
* Real-time processing and routing
* Monitoring and analytics
* Support and maintenance
* Platform features and integrations

<Note>
  The platform fee is the same across all plans. Your subscription tier determines how many concurrent calls you can handle and what features you have access to.
</Note>

***

## 🎯 Total Cost Breakdown

Your total cost per minute for voice calls = **Platform Fee + STT Provider + TTS Provider + LLM Costs + Telephony (if applicable)**

**Example calculation:**

* Platform fee: \$0.03/min
* STT (AssemblyAI): \$0.0088/min
* TTS (Google Cloud): \$0.0110/min
* LLM (GPT-4o Mini): \~\$0.002/min
* **Total: \~$0.052/min or $5.20 per 100 minutes**

<Warning>
  We include a 10% markup on provider costs unless you're on the **Enterprise plan**. Enterprise users are charged the **exact provider costs** with no markup.
