Defaults: HVAC avg job $800 (Invoca 2024); 5 missed calls/week (BrightLocal 2024, 40% miss rate on ~12 weekly inbound); 70% Anna capture rate (industry range 65-75%); VantaWeb Pro $299/mo. Formula: avg_job × missed_calls_per_week × 52 × 0.70 = annual recovery.

How the math works

Annual revenue at risk = average job value × missed calls per week × 52. This assumes every missed call would have converted — a ceiling, not a floor. Realistic close rates for HVAC run 36-55% (Invoca 2024); for roofing 30-45%. Apply your actual close rate mentally for a conservative read.

Anna capture rate: 70%. AI receptionists recover 65-75% of missed calls (after-hours + overflow). The remaining 25-30% are complex dispatching situations that still need a human.

What the calculator misses: Customer lifetime value (3-5x single-job ticket for service trades), emergency call premium pricing (1.5-2x), review damage from unanswered calls, and language-gap attrition for Spanish-preferring callers. The real number is usually higher.
