AI cost calculator

AI call costs

Estimate telephony, voice AI and supporting service costs. Compare billing models and calculate a budget using your own figures.

Pricing models

AI charging models

Use the model that matches your provider contract. A managed agent price may already include speech and model usage.

Managed voice agent

Billable agent minutes × the provider’s rate per minute. Add other items only if the contract bills them separately.

Realtime audio model

Input, cached and output audio tokens, plus text tokens, each at its own rate. Do not estimate tokens from call length.

STT + LLM + TTS

Transcribed audio time, language model tokens and ynthesised characters or audio units, as each provider bills them.

Calculator

Estimate costs

The preset rates are examples in USD, not vendor prices or a quote. Replace them with your contracts and measured usage.

Use the billable session time from your provider. It can include silence and processing time. The rate covers AI processing, so no token or speech charges are added.

Use the total usage your provider reports for the whole conversation. Uncached input is the reported input minus cached input, so no token is counted twice. Transcription or tools billed separately go under additional costs.

This example prices speech recognition by duration and speech synthesis by characters. If your provider bills audio tokens, use its reported usage instead.

Text tokens

Extras and markup

Add hosting, number rental, recording, tools or platform fees. Markup is applied to the total cost and is not the same as gross margin.

Metering

From usage to invoices

  1. Link sessions

    Customer, call, call leg, agent session and provider request share identifiers. A transfer can create a new billable leg.

  2. Remove duplicates

    Collect call records and provider-reported usage. Remove duplicates, and replace cumulative snapshots instead of adding them.

  3. Apply tariffs

    Rate cards are versioned by date, provider, model, direction and currency. Cached and uncached input have different prices.

  4. Separate costs and charges

    Supplier cost and customer charge are separate ledgers. Packages, free units, rounding and reseller rules apply to the customer side.

  5. Reconcile invoices

    Compare collected usage with provider invoices, keep corrections traceable and compare cost per resolved task with cost per call.
