Why this isn't trivial
The part people underestimate: per-minute cost combines transcription, LLM and synthesis rates, which vary independently by provider. In practice the biggest savings come from mixing the cheapest capable STT, LLM and TTS providers, so it is worth modelling before you commit.
How it's calculated
We estimate this by adding per-minute transcription, per-turn LLM and per-character synthesis at each provider's rate. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Can I mix providers?+
Yes — use the cheapest STT, LLM and TTS that meet your quality bar.
What dominates per-minute cost?+
Often speech in/out for longer calls; the LLM for turn-dense ones.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
