The number is uncertain — most published stats are vendor marketing — so below is the actual arithmetic with every assumption visible, so you can rerun it with your own numbers and disagree precisely. ## The stats everyone quotes — and where they come from Three numbers circulate through every article about missed calls, usually unsourced. In the interest of honesty, here is where they actually come from and how much to trust them: - **"62% of calls to small businesses go unanswered."** This figure traces to call-tracking studies republished by vendors (AgentZap, CallBird, and others). The exact percentage varies by study (55–70%), but the direction is robust: most small-business calls ring out, hit voicemail, or arrive after hours. Treat "roughly 6 in 10" as the defensible claim. - **"The average missed HVAC call is worth $350."** Vendor-published averages (Aira, Higrovi, and similar reports) blend service calls with quote requests. Your real number is your average ticket × your close rate on answered calls — compute it below instead of trusting anyone's blend. - **"After-hours emergency calls average $1,400 in HVAC."** Same class of source. Directionally right — after-hours work carries emergency pricing and bigger scopes — but use your own after-hours invoices if you have them. None of these numbers deserve two decimal places. All of them deserve the response "so what's _my_ number?" — which is the point of this post. ## The math, per trade The formula is four terms: > Missed calls/month × % that are real job inquiries × close rate you'd have had × average ticket = monthly leak Below are worked examples with deliberately conservative inputs. A "real job inquiry" excludes spam, wrong numbers, and vendors — we assume only half of missed calls were ever potential work, and we assume you'd close only half of those you answered. Trade Missed calls/mo Real inquiries (50%) Would-close (50%) Avg ticket Monthly leak **Plumbing** (2–5 techs) 30 15 7.5 $400 **$3,000** **HVAC** (5–10 techs, shoulder season) 40 20 10 $450 **$4,500** **HVAC** (same shop, first heat wave) 100 50 25 $500 **$12,500** **Restoration** (emergency line) 8 6 (75% — people don't casually call restoration) 3 $9,000 **$27,000** **Cleaning** (recurring contracts) 25 12.5 6 $180/mo × 12 = $2,160 LTV **$12,960 in annual contract value** Two things jump out of the table. First, **restoration is its own universe**: tickets are so large that a handful of missed emergency calls outweighs every other trade's entire leak. Second, **the leak concentrates in surges** — the heat-wave row is the same company as the row above it, one month apart. Whatever answers your phone has to survive your busiest week, not your average one. ## Why missed after-hours calls are worse than the average The formula treats all missed calls equally; reality doesn't. After-hours callers are disproportionately _emergencies_ — higher tickets, higher urgency, and near-zero patience. Published analyses of contractor call data (the $45,000–120,000/yr lost-revenue range that vendors like to quote) get their headline numbers mostly from this bucket. An after-hours caller with water coming through the ceiling does not leave a voicemail; they call the next result on Google, and the first company to answer with a plan wins. That's not a statistic — ask any restoration owner how they win TPA-adjacent referral work. ## Run your own number 1. Pull two weeks of call logs from your phone system or carrier portal. Count calls that rang out, went to voicemail, or arrived outside business hours. 2. Listen to the voicemails that were left — count what fraction were real work. 3. Multiply: missed × your inquiry fraction × your close rate × your average ticket. Then double it for your surge month. 4. Compare against the cost of answering: a hire (~$3,000/mo), a human answering service (see [the cost guide](/blog/answering-service-cost)), or a flat-rate AI service ($149–299/mo for [CallsAround](/pricing)). For most shops the arithmetic isn't close: if your leak is $3,000/mo, anything under $300/mo that answers reliably pays for itself with the first saved job — the remaining question is only _which_ option fits your trade, which we cover in [AI receptionist vs. answering service](/blog/ai-receptionist-vs-answering-service). ## Methodology notes Sources referenced: unanswered-call rates and missed-call value ranges as published in vendor call-data reports (AgentZap, CallBird, Aira, Higrovi, 2024–2026 editions); after-hours multipliers from the same. These are marketing-adjacent sources — which is exactly why this post shows the formula instead of leaning on their conclusions, uses conservative 50% haircuts twice, and encourages you to rerun everything with your own call logs. If you have two weeks of real data that contradicts these ranges, trust your data. What actually happens when someone calls _your_ business after hours? We'll test it — free.
