Across every industry that relies on the phone to win business, the pattern is the same: a large share of calls go unanswered, the caller moves on, and the revenue disappears without anyone logging the loss. The benchmarks vary by industry — contractors miss roughly 62% of calls, restaurants 43%, dental practices 38%, and law firms 35% — but the outcome is consistent: if you don't answer, a competitor does. This page aggregates the sourced 2026 data by industry into one citable reference.
The master benchmark table: missed-call rates and cost by industry
| Industry | Calls missed | Cost per missed call / annual loss | Source |
|---|---|---|---|
| Home-service contractors (HVAC, plumbing, roofing, etc.) | Up to 62% | $275–$1,200 per call; $45K–$120K/yr at 5–10 missed calls/week | Invoca; GetAira; Adeltium, 2026 |
| Restaurants | ~43% (~150 calls/month) | $28,728–$292,000/yr per location; ~$20B industry-wide | Hostie AI; QSR Magazine, 2026 |
| Dental & medical practices | 38% during business hours | $250–$350 per first visit; $100K–$140K/yr per practice | Peerlogic, 2026 (4,280 calls, 26 practices) |
| Law firms | 35% during business hours | $109 billion/yr industry-wide | Law Leaders, 2025 (1,200 firms) |
| Real estate agents | Avg. 917-min (>15 hr) response delay | 78% of buyers hire the first responder; teams responding in <5 min convert 3–4x higher | iHomefinder; AgentZap; Conversion Realtor, 2026 |
| Salons & med spas | Not benchmarked by call-miss rate; 5% no-show + ~14% cancellation | Each empty slot = lost appointment revenue; 48% of clients less likely to rebook without 24/7 booking | Zenoti, 2025–2026 |
| Pest control companies | Not benchmarked by call-miss rate; 87% expect <24h response | +5% retention = +25–95% profit; new customer costs up to 7× more to acquire | FieldRoutes, 2026 |
Home-service contractors: the highest miss rate in the benchmark
Small home-service businesses miss as many as 62% of inbound calls — the highest miss rate of any industry in this benchmark (Invoca; GetAira, 2026). The reason is structural: owners and technicians are on job sites without a dedicated receptionist, so the phone rings and no one picks up. The revenue hit is steep because job values are high: each missed call is worth an estimated $275 to $1,200 depending on the trade, and a contractor missing just 5 to 10 calls a week loses $45,000 to $120,000 a year (Adeltium; InstantBusinessPro, 2026). Making it worse: 85% of callers who can't reach you won't leave a voicemail — they call the next contractor on the list (PATLive, cited by GetAira, 2026).
Restaurants: 43% missed — right at the dinner rush
The average restaurant misses 43% of its phone calls — roughly 150 a month — and up to 81% of those missed calls are real orders or reservations (Hostie AI; QSR Magazine, 2026). The timing makes it worse: between 5pm and 8pm, when approximately 47% of daily phone orders come in, restaurants are also at peak service and miss 32% of calls during that window. Industry-wide, unanswered calls cost an estimated $20 billion a year. Per restaurant, the annual loss ranges from $28,728 to $292,000 depending on volume and average order value (RingFoods, 2026).
Dental and medical front desks: 38% unanswered, 67% gone forever
A 2026 Peerlogic study of 4,280 calls across 26 dental practices found 38% go unanswered during business hours — and when a patient can't get through, 67% immediately call another practice instead of trying again. Only about 14% leave a voicemail. A single missed new-patient call costs $250–$350 in lost first-visit production, but the real figure is the patient's lifetime value — estimated at $10,000 or more over 8–10 years of treatment. In total, missed calls cost the average single-location dental or medical practice $100,000 to $140,000 a year (Peerlogic, 2026).
Law firms: 35% unanswered, $109 billion lost industry-wide
A 2025 national audit by Law Leaders placed 1,200 calls to small and mid-sized firms during peak business hours and found 35% went unanswered, contributing to an estimated $109 billion in lost industry revenue per year. The response-time problem compounds it: Hennessey Digital's 2025 study of 1,333 law firms found the median firm takes 13 minutes to respond to an online lead, 26% never respond at all, and only 25% reply within 5 minutes. Since most legal clients hire whoever responds first, slow intake costs cases that were never counted as lost.
The mechanics of why calls get missed
The same structural problem drives high miss rates in every industry: the person who answers calls is also doing something else. Front-desk staff are helping the patient in the chair. Restaurant staff are serving guests. Contractors are on the job. When capacity is maxed out — which is when calls peak — something has to give, and the phone loses. There are three additional patterns that turn a missed call into a lost sale:
- Callers don't leave voicemails. BIA/Kelsey research (via Capture Client) finds 67% of callers won't leave a voicemail; Ambs Call Center puts the share that simply call a competitor at 85%. Voicemail is not a fallback — it's the end of the lead.
- After-hours calls land nowhere. Businesses are staffed for business hours; callers don't stop calling after 5pm. Every after-hours ring that hits voicemail is a lead that paid for itself in marketing and vanished.
- The average missed call costs $12.15 directly (Ambs Call Center, 2025), but that ignores job value — in home services the figure is $300–$1,200 per call, in dental $250–$350 per first visit, and in legal, cases can be worth tens of thousands.
The speed-to-lead angle: being first matters as much as answering
Even when a business answers, response speed determines who wins. The MIT Lead Response study (Dr. James Oldroyd) found that responding within 5 minutes makes you 100x more likely to make contact and 21x more likely to qualify the lead than waiting 30 minutes (Harvard Business Review / MIT). For real estate, the data is unambiguous: 78% of buyers work with the first agent to respond, yet the average agent takes 917 minutes — over 15 hours — to follow up (iHomefinder; AgentZap, 2026). In law, the median firm takes 13 minutes just to respond to an online lead (Hennessey Digital, 2025). A 2026 Blazeo benchmark of 573 companies found businesses using AI or automated routing hit the under-15-minute mark 62.5% of the time versus 39.1% for manual-only operations.
| Response time | What happens to your lead |
|---|---|
| Within 5 minutes | 100× more likely to make contact; 21× more likely to qualify (HBR / MIT) |
| Within 1 minute vs. 2 minutes | 391% more conversions (Velocify, 3.5M leads) |
| Average business response | 47 hours — the lead is long gone (HBR / MIT) |
| AI-routed firms vs. manual | 62.5% under 15 min vs. 39.1% (Blazeo, 2026, 573 companies) |
What actually fixes a missed-call problem
There are two tools that directly address the missed-call and slow-response problems in the data above:
- AI voice agents: an AI receptionist answers every call on the first ring, 24/7 — during peak hours, after hours, and on weekends — qualifying the lead and booking the job before it reaches voicemail. Per-call cost for AI voice is roughly $0.40 vs. $7–$12 for a human agent (a 90–95% reduction), and companies report 3-year ROI between 331% and 391% (Nextlevel.ai; Forrester).
- Missed-call text-back: when a call can't be answered, an automated SMS fires within seconds. SMS earns roughly a 98% open rate and a 45% response rate (Notifyre / Omnisend) — far above voicemail. With 67% of callers refusing to leave a voicemail, a text-back turns a lost call into an active text conversation.
