Retell AI Pricing Explained
2 min read · Bolcho
Retell AI is a reliable, developer-focused platform priced in dollars: a per-minute platform fee on top of the STT, LLM and TTS provider costs. For Indian teams the markup, forex and card-only billing matter at volume. Here's what a Retell minute really costs and how Bolcho's rupee-near-cost model compares.
How Retell AI pricing works
Retell charges a per-minute platform fee plus the underlying provider costs for transcription, the LLM and synthesis. Telephony and compliance are largely yours to arrange.
It's a fair model for a US-centric developer platform — but it's USD on a card, with a per-minute markup on every conversation, which is exactly what compounds for high-volume Indian call flows.
What a minute actually costs
Once you convert to rupees and add the platform fee on top of provider (STT + LLM + TTS) costs, a minute of Retell AI conversation usually lands well above what the same call costs on Bolcho.

Bolcho meters to the token and character and bills near raw provider cost in ₹, using caching and smart routing to cut roughly 20% more, with no per-minute platform markup. You pay in rupees over UPI/netbanking and get GST invoices.
Billed in ₹, near cost
No opaque per-minute markup. Meter to the token and character, pay over UPI/netbanking, get GST invoices — and estimate cost per minute before you launch.
Cutting your voice AI bill
The biggest cost levers, whichever platform you're on:
- Cache repeated phrases (greetings, disclaimers, confirmations) instead of re-synthesising them — Bolcho does this automatically.
- Route to the cheapest capable model per task instead of one premium model for everything.
- Keep prompts tight and use retrieval so the LLM reads less on every turn.
- Use good endpointing so you're not paying for dead air at the end of turns.
- Bill in ₹ near provider cost to remove the platform markup entirely.
