KPI Glossary
Definitions and concise guidance for campaign metrics.
Contact rate
Definition: answered calls ÷ dialed attempts. Use to measure list quality and dialer performance. Target: 90–95% for warm lists.
Booking rate
Definition: bookings ÷ contacted leads. Shows script effectiveness at converting conversations to appointments.
Warm transfers
Definition: percentage of calls successfully transferred to a human with context passed. High rates indicate reliable handoffs.
Latency (p50 / p90 / p99)
Definition: conversational turn latency percentiles. p50 = median, p90 = 90th percentile. Target: sub‑800ms turns overall.
Qualification rate
Definition: qualified leads (per your criteria) ÷ contacted leads. Use to measure lead readiness and script qualification logic.
Cost per booking (CPB)
Definition: spend ÷ bookings. Include platform fee, usage, and number rental for accurate comparison.
ROI
Definition: (Revenue − Spend) ÷ Spend. Revenue = bookings × close rate × deal value. See How to Calculate ROI.
Show rate
Definition: kept appointments ÷ bookings. Important for downstream conversion to closed deals.
Deliverability
Definition: success rate of outbound call attempts reaching live phones (not blocked/filtered). Improving via number pools and rotation.
How to use these metrics together
Start with Contact rate to validate list quality, then Booking rate and Qualification rate to evaluate script performance. Use CPB and ROI to assess commercial impact.
