Breakdown

Formula: monthly = minutes × (Vapi hosting $0.05 + STT + LLM + TTS + transport) + package fee + add-ons. Models are passed through at provider cost; defaults are the midpoints of Vapi's own example ranges (Deepgram $0.0095–0.0099, OpenAI $0.0077–0.0452, ElevenLabs $0.0146–0.0238 per min), so 1,000 minutes ≈ $82–$129 / month. Transport: Vapi Telephony / SIP, WebSockets and Daily WebRTC free; Twilio inbound $0.008, outbound $0.014; Vonage $0.00814; Telnyx $0.0055 per min (charged by the provider). Packages: none ($5 free credit, 4 concurrent calls, 1 number), Core $29 / mo (10 concurrent, 5 numbers), Pro = 10% of hosting fee with $999 / mo minimum (30 concurrent, 10 numbers), Premier custom. Add-ons: $10 per extra concurrency line, $20 per extra organization, HIPAA $2,000 / mo.

- About $82–$129 on Vapi's own example: hosting $50 + STT ~$10 + LLM $8–$45 + voice $15–$24, no package. Using range midpoints: $50 + $9.70 + $26.50 + $19.20 = $105.40, i.e. $0.1054 per minute.
