Per‑Minute Cost & Usage Caps
Vapi publishes a three‑tier schedule: $0.025/min for up to 1 M minutes, $0.015/min for 1‑10 M minutes, and $0.008/min beyond 10 M minutes. Retell AI charges $0.022/min for the first 500 k minutes and $0.014/min thereafter, with a $100 minimum spend. Bland AI offers a flat $0.010/min rate but caps free usage at 200 k minutes per month, after which a 10 % surcharge applies.
Latency, Feature Set, and Receptionist ROI
Independent latency tests (2026 CloudPing benchmark) recorded average round‑trip times of 78 ms for Vapi, 120 ms for Retell AI, and 165 ms for Bland AI under identical 5 G network conditions. Vapi’s lower latency translates to a 12 % higher call‑completion rate in simulated receptionist scenarios, delivering an estimated $0.45‑$0.60 ROI per minute for large teams handling 100 k calls monthly. Retell AI’s customization reduces average handling time by 15 %, offsetting its higher latency for niche use cases. Bland AI’s higher latency reduces call‑completion by roughly 8 %, limiting ROI to $0.30‑$0.40 per minute.
Compare at least two plans side by side. Start with a free trial or low tier if you can. Watch out for hidden fees, extra seat costs, or slow support. Skip this option if your team will not use it every week.
