Retell AI vs Vapi vs ElevenLabs Agents on price
With the cheapest picks each lists, a minute costs Retell AI $0.07, Vapi $0.0621 and ElevenLabs Agents $0.08, before the language model and the phone line; with the dearest, $0.155, $0.086 and $0.08, so which is cheaper depends on what you pick. At 10,000 minutes a month that comes to $700 on Retell AI, $621 on Vapi and $799 on ElevenLabs Agents, so Vapi is cheaper before the model. Retell AI charges $0.055 a minute for Retell Voice Infra, plus $0.015 for the cheapest voice it lists (Retell Platform Voices); Vapi charges $0.05 a minute for Vapi hosting, plus $0.0121 for the cheapest speech to text and voice it lists (AssemblyAI and Cartesia); ElevenLabs Agents charges $0.08 a minute with speech to text and voice included. Retell AI sells the model by the minute, while Vapi and ElevenLabs Agents pass the model provider's own price through, so the model's share depends on how many tokens your calls use.
Part by part
A minute of conversation, as each vendor's pricing page splits it:
| Part | Retell AI | Vapi | ElevenLabs Agents |
|---|---|---|---|
| Platform fee | $0.055 (Retell Voice Infra) | $0.05 (Vapi hosting) | $0.08 (Call minute), speech to text and voice included |
| Speech to text | No separate price listed | $0.00521 (AssemblyAI) to $0.01221 (OpenAI), at the provider's price | Included in the $0.08 rate |
| Language model | $0.0016 (GPT 5 nano) to $0.64 (GPT 6 Astra, fast tier) | $0.006 (Google) to $0.04523 (OpenAI), at the provider's price | By the token, at the provider's own price; no per-minute figure |
| Voice | $0.015 (Retell Platform Voices) to $0.10 (ElevenLabs v3) | $0.00689 (Cartesia) to $0.02383 (ElevenLabs), at the provider's price | Included in the $0.08 rate |
| Phone line | $0.015 to $0.80 on Retell's numbers; no Retell charge with your own SIP trunk | Free over Vapi telephony or SIP; other carriers at their own price, $0.0055 to $0.014 | No ElevenLabs fee; your carrier bills you (Twilio charges $0.0085 a minute inbound, $0.014 outbound) |
| A minute, before the language model and the phone line | $0.07 to $0.155 | $0.0621 to $0.086 | $0.08 |
| With a US inbound line | $0.085 to $0.17 Retell number: United States (Twilio): $0.015 | $0.0621 to $0.086 Vapi Telephony / SIP: $0 | $0.0885 Twilio local number, inbound, at Twilio's price: $0.0085 |
The range runs from the cheapest to the dearest option each vendor lists for every part, without add-ons. The US line is the vendor's own where it sells one, otherwise a Twilio local number at Twilio's inbound price; number rental is left out. The language model is left out because at least one side bills it by the token with no per-minute price; how each bills it is below.
What a month costs
| Minutes a month | Retell AI | Vapi | ElevenLabs Agents |
|---|---|---|---|
| 100 minutes | $7.00 to $15.50 | $6.21 to $8.60 | $6.80 |
| 1,000 minutes | $70.00 to $155 | $62.10 to $86.04 | $78.80 |
| 10,000 minutes | $700 to $1,550 | $621 to $860 | $799 |
| 50,000 minutes | $3,500 to $7,750 | $3,105 to $4,302 | $3,999 |
Each side's cheapest picks on the plan that costs least for that volume, then (smaller) its dearest picks; bold marks the cheaper, before the language model and the phone line. Plans with included minutes or a lower rate are counted where they lower the bill; phone number rental, extra concurrency and taxes are left out.

- Vapi: “<500ms average latency”
- ElevenLabs Agents: “Build, deploy, and manage AI voice agents that handle inbound and outbound calls, with sub-500ms latency and 70+ languages.” In the page's structured description; the visible text of elevenlabs.io/agents says "ultra-low latency" without a figure.
These are the vendors' own claims. None says what is timed or under what conditions, and they don't use the same measure, so they can't be ranked against each other; test on your own calls.

How do you calculate the minutes? Each call is tracked to the nearest second. At the end of each billing cycle, we charge based on your total accumulated minutes. No rounding up per call, no inflated bills. Does billing continue after a transfer? Once the call is transferred, the AI voice agent fee stops. Only the telephony fee continues for the remainder of the transferred call. Am I charged during silence or hold time? Yes. Billing covers the entire duration of the call because the speech-to-text engine remains active and listening throughout, even during silence.
retellai.com/pricing
Voice infra : Retell’s conversation voice engine. This is the flat per-minute platform cost of running the real-time call, separate from LLM and telephony costs. LLM : the per-minute cost of the language model your agent uses, which varies by model. Telephony : per-minute call rates and monthly phone number fees for Retell-provided numbers. Custom telephony (SIP trunking) carries no Retell telephony charge.

Rule 2: LLM Price Scaling for > 4,000 Token Prompt Length When it applies: Agents that use more than 4,000 LLM tokens in their prompts Billing adjustment: Duration is scaled proportionally based on token usage

Scaling Factor = Prompt LLM Tokens ÷ 4,000 Billed Duration = Original Duration × Scaling Factor (rounded up) Example: Call duration: 60 seconds LLM tokens used: 4,800 Scaling factor: 4,800 ÷ 4,000 = 1.2 Billed duration: 72 seconds (12 seconds additional charge)

elevenlabs.io/pricing/agents. The "ElevenAgents pricing" table; its columns run Free / Pay as you go, Starter, Creator, Pro, Scale, Business.
ElevenAgents plans are billed by call minutes, not by the shared credit pool. Included call minutes and concurrent calls per plan: Free 15 minutes / 4 concurrent calls; Starter 75 minutes / 6; Creator 275 minutes / 10; Pro 1,238 minutes / 20; Scale 3,738 minutes / 30; Business 12,375 minutes / 40. Additional call minutes cost $0.08 per minute (burst pricing $0.16 per minute, double the standard rate, when you exceed your concurrency limit), and text messages cost $0.003 each. LLM usage is billed separately on top, based on the model you choose. ElevenLabs does not charge extra for telephony, but if you connect an external provider such as Twilio or a SIP trunk, that provider bills you directly for its own charges.
elevenlabs.io/pricing/agents
No. Telephony is included on every plan, and phone calls are billed at the same call-minute rate as any other channel, so ElevenLabs adds no telephony fee. You connect your own provider, such as Twilio or a SIP trunk, and that provider bills you directly for the carrier side of the call at whatever rate you have with them.
