AI Cost Calculators
AI Voice Agent Cost Calculator
Estimate the complete cost of an AI voice agent using current provider rates you enter for speech recognition, LLM usage, voice generation, telephony, platform fees, recording, and setup.
Enter Your Voice Agent Usage
Add your workload and the current rates from the providers in your voice-agent stack.
* Important: Price fields are blank by design. Copy the current rate for each exact provider, model, region, plan, and billing unit from its official pricing page.

A voice agent is rarely one bill. Speech recognition, the language model, generated voice, phone calls, platform fees, recording, and setup can all contribute to the final cost. This calculator brings the full stack into one estimate.
Calculating the Full Voice Agent Stack
Start with monthly calls and average call duration. Add an overhead percentage for repeated, failed, test, or reconnected calls that may still create billable minutes.
Enter the per-minute prices for speech-to-text, telephony, platform orchestration, and recording. Then add the LLM token rates and text-to-speech character rate used by your chosen stack.
The result shows cost per call, cost per billable minute, cost per 1,000 calls, monthly spend, annual spend, and a component-by-component breakdown.
Estimating LLM Usage More Realistically
Voice agents usually make several LLM requests during one call. Each request may include system instructions, conversation history, retrieved knowledge, tool results, and the latest user message.
Use observed input and output tokens per call minute when production logs are available. Before launch, test a sample conversation and use a cautious average.
Longer calls do not always grow linearly when full conversation history is replayed. Add extra room to the input-token estimate when the agent keeps long context.
Planning Text-to-Speech and Telephony Costs
Text-to-speech is based on the part of the call spoken by the AI. Enter the AI speaking share and the average spoken characters generated per minute.
Telephony can vary by country, inbound or outbound direction, phone number type, recording, carrier, and SIP setup. Use the exact rate for the traffic you expect.
Platform prices may cover orchestration only, or they may include parts of the speech and model stack. Avoid entering the same charge twice.
Practical Decisions This Tool Supports
- Set a realistic voice-agent budget before building.
- Compare a managed platform with a custom stack.
- Estimate cost per call and per 1,000 calls.
- See which part of the stack drives the monthly bill.
- Test longer calls, higher volume, and retry overhead.
- Amortize one-time setup work across several months.
- Check whether the planned stack fits a monthly budget.
Using Official Provider Prices
Every price field is blank by design. Beeija does not insert unverified example prices or silently assume a provider. Copy the latest rates from the official pages for your speech-to-text, language model, text-to-speech, telephony, recording, and voice-agent platform providers.
Check whether a platform rate already includes model, speech, or telephony costs. Also review minimum billing increments, free allowances, regional prices, concurrency charges, subscriptions, and enterprise discounts.
Frequently Asked Questions
What costs should be included in an AI voice agent budget?
A complete estimate can include speech-to-text, LLM input and output tokens, text-to-speech, telephony, platform or orchestration fees, call recording, phone numbers, fixed subscriptions, and setup work.
Why is LLM cost entered as tokens per call minute?
Voice agents can replay conversation history, instructions, and retrieved context during each turn. Entering average input and output tokens per call minute lets you use real logs or a careful workload estimate.
How is text-to-speech usage estimated?
The calculator uses the share of the call spoken by the AI, multiplied by spoken characters per minute and the TTS price per 1,000 characters.
What does retry and failed-call overhead mean?
It covers repeated calls, reconnects, test traffic, workflow retries, or failed sessions that still create billable usage.
Can this calculator be used with Vapi, Retell, Bland, or a custom stack?
Yes. Enter the rates from your chosen platform and providers. The tool does not lock the calculation to one vendor.
Why are the price fields blank?
They are blank to protect accuracy and trust. Enter the current official rates for the exact providers, plans, regions, and models you are considering. Beeija does not present example prices as verified live prices.
