Retell's calculator adds four parts. Retell voice infrastructure is a fixed $0.055/min. Text-to-speech depends on the voice provider. The LLM depends on the model you pick, and telephony depends on where the number is.
| Component | Published rate (retellai.com, 12 Oct 2026) |
|---|---|
| Retell voice infrastructure | $0.055/min |
| Text-to-speech | $0.015/min (Retell, Minimax, Fish, Cartesia, OpenAI, Inworld); ElevenLabs Flash $0.040; Multilingual v2 $0.06; v3 Conversational / v4 Turbo $0.08; v3/v4 $0.10 |
| LLM (examples) | GPT 5.6 Terra and Claude 5 Sonnet $0.064/min (marked Recommended); GPT 5.4 $0.080; GPT 5.5 $0.16; Gemini options $0.0096 to $0.048; Claude options $0.0032 to $0.16 |
| Telephony | $0.015/min on the default selection; varies by country; no charge for SIP trunking or custom telephony |
| Per-minute add-ons | Knowledge base +$0.005; advanced denoising +$0.005; safety guardrails +$0.005; PII removal +$0.01; AI quality assurance $0.10 (first 100 minutes free) |
| Monthly fees | Phone number $2.00; verified number $10.00; concurrency $8.00 each beyond the 20 included; knowledge base $8.00 each beyond 10 free; SMS $20.00 |
Take a configuration built only from figures on Retell's page. Voice infrastructure at $0.055, a $0.015 voice, GPT 5.6 Terra at $0.064 and telephony at the default $0.015 add up to $0.149 per minute. A 2-minute call is 2 × $0.149 = $0.298, before any add-ons or monthly fees.
Bring your own SIP trunk and Retell's telephony line drops to zero, giving $0.134/min or $0.268 for 2 minutes, plus whatever your carrier charges. Swap to an ElevenLabs Flash voice ($0.040) on Retell telephony and the rate becomes $0.174/min, or $0.348 for the call.
Two figures are ambiguous. The page shows telephony at $0.015/min for the default country selection, but the rates for other countries, including India, were not visible in the page content we checked. The page also does not explain which configurations produce the $0.07 and $0.31 ends of the headline range.
GRX10 Voice AI is priced at $0.119/min for the platform (₹7.99/min in India), with telephony at carrier cost as a separate line (₹0.85/min on managed SIP in India). The voice model is included and there is no language surcharge. A typical 2-minute call is about $0.24 or ₹16 on the platform line. Retell can come in cheaper if you pick a low-cost LLM and voice, and its per-second billing and transfer rule are clearly published.
