Voice agents pay back when call volume × duration × human cost outweighs platform per-minute fees. Yours does.

Estimates only — not a quote. Real numbers depend on telephony, LLM token usage, languages, and integrations.

What this calculator doesn’t include

Setup cost (typically $5K – $15K for a production-grade voice agent on Zaibex’s stack), telephony line fees, integration work into your CRM/scheduling, and ongoing eval/monitoring. We scope these in writing on day one.
