Vapi is infrastructure for building AI voice agents. The pricing page opens with a friendly number — US$0.05 per minute — but that is what Vapi charges, not what a call costs you.

The page splits cost into two layers
Layer one — Vapi hosting (explicitly excludes model provider costs)
Item
Build
Calls
US$0.05 / min
SMS / chat
US$0.005 / message
Concurrency
10 lines included, US$10 per line/month after
Included allowance
card states “60+ minutes included”
Layer two — model provider costs (STT, LLM, TTS)
Listed as At cost (US$0 if you bring your own API key).
So the honest formula is: per-minute cost = US$0.05 + speech-to-text + LLM + text-to-speech. Our existing record puts the all-in range at roughly US$0.13–US$0.31+ per minute, but that figure is derived from component pricing and second-hand sources — not a published Vapi number. Treat it as an order of magnitude, not a quote.
Two limits that are easy to miss
Retention is short. Build keeps call history for 14 days and chat history for 30 days; only Scale gets custom retention. If you need audits, dispute handling or training data, plan your own export.
Compliance is not in Build. SSO, RBAC and SOC 2 show “-” for Build and require Scale (annual contract). HIPAA and Zero Data Retention are paid add-ons on both tiers: US$2,000/month and US$1,000/month respectively.

The question is whether you need “does it run” or “someone is accountable when it breaks.” Prototypes and low-volume outbound: Build. A production support line with regulatory exposure: Scale, where you are buying SLAs and compliance rather than a lower per-minute rate.
Who should not pick Vapi
Non-developers. This is developer infrastructure, not a drag-and-drop bot builder.
A small shop wanting one support bot. Do the maths first — from ~US$0.13/min plus your own maintenance time, a packaged product may be cheaper.
Anyone with strict retention rules. The default is 14 days, and Zero Data Retention is a US$1,000/month add-on that belongs in the budget from day one.
Figures read from the live pricing page on 2026-09-06 with a rendering browser; the all-in per-minute range is our derived estimate, not a vendor figure, and is labelled as such. Prices and terms change; the official page is authoritative.
