The Short Answer

No reliable universal benchmark says what a missed call costs across trades, real estate, hospitality, and automotive. The defensible figure comes from your own call logs: missed qualified opportunities multiplied by observed booking rate and gross profit per booking. Treat published averages without a direct primary source as unverified.

Why Universal Benchmarks Fail

Call intent, job value, margin, opening hours, location, and follow-up speed vary too much for one cross-industry number. Top-line revenue is also the wrong input when the decision is about economic impact; gross profit is usually more useful.

A Transparent Calculation

Use a representative measurement period and record:

• total inbound calls;
• unanswered calls;
• unanswered calls that were genuine opportunities;
• the booking rate for comparable answered opportunities;
• gross profit per booked job; and
• opportunities recovered through callback or text follow-up.

Calculate estimated unrecovered opportunity as:

unrecovered qualified calls ? observed booking rate ? gross profit per booking

Illustrative example: if a business identifies 12 unrecovered qualified calls, observes a 50% booking rate on comparable answered calls, and earns $200 gross profit per booking, the estimate is 12 ? 50% ? $200 = $1,200. Those are assumptions for demonstrating the formula, not industry research.

Report the Assumptions

Publish the period, call source, classification method, booking definition, and whether repeat customers were included. Keep revenue and gross-profit calculations separate. If the sample is small, describe the result as an internal estimate rather than a benchmark.

Compare Solutions Honestly

Price any response option against the same measured opportunity. Help Genie’s published pricing lists Starter at $199 a month, Pro at $299 a month covering every channel from one knowledge base, and Enterprise at $499 a month, with a free way to test first.

Use the ROI calculator for a first pass, then recalculate after deployment using actual answered calls, qualified leads, bookings, and gross profit. A tool has demonstrated value only when measured results improve enough to cover its full cost.
