How many calls does a small business actually miss?
More than most owners think. CallRail's 2025 data across more than 220,000 businesses puts the figure at roughly 28–30% of calls going unanswered. Invoca's July 2026 analysis of over 70 million calls found only 56% were answered by a person. Smaller studies run higher — up to 62% — but treat that as the top of the range, not the norm.
The honest answer is a range, because the studies measure different things. The largest samples — CallRail and Invoca — land between roughly 3 and 4.5 calls in 10 not answered live. The highest figure, 62%, comes from a 411 Locals study of 85 businesses over 30 days. That study counted a call as "unanswered" if it went to voicemail, which inflates the number compared with studies that only count calls nobody picked up or returned. With a small sample and a strict definition, 62% is a ceiling, not an average. But even the most conservative large-sample number — 28% — means a business taking 200 calls a month is missing about 56 of them.

What happens after a missed call?
Usually, nothing good. Quo's 2026 analysis of 16.7 million missed calls found 69% never got a callback within 48 hours. By then it rarely matters: CallRail found 82% of consumers say they would call a competitor after an unanswered call, and up to 85% of callers who don't reach someone never try again.
This is the part owners underestimate. A missed call is not a delayed sale — it is usually a finished one. The caller has a problem now: a broken furnace, a leaking pipe, a toothache. They work down the search results until somebody answers. Lead Connect's speed-to-lead research found 78% of buyers go with the business that responds first, which means the competitor who picks up does not just get that job — they often get the customer's future work too. Meanwhile your phone log shows a call you may not even notice you missed.
Why doesn't voicemail save you?
Because most callers won't use it. Around 80% of callers who reach voicemail hang up without leaving a message. Of the minority who do leave one, the follow-through is weak: 69% of missed calls in Quo's data never received a callback within 48 hours. Voicemail feels like a safety net, but for new customers it mostly is not one.
Voicemail works for existing customers who already trust you and will wait. It fails for the calls that matter most to growth — first-time callers comparing two or three businesses. They have no loyalty, no reason to wait, and a competitor one tap away. There is also a timing problem: 42% of service calls arrive outside 9–5, according to ServiceTitan. Those calls land in voicemail by default, sit there overnight or all weekend, and by morning the job is usually booked somewhere else.
How do I calculate what missed calls cost me?
Use your own numbers in this formula: monthly lost revenue equals missed calls, times 51% (the share that are real leads), times 85% (the share who never call back), times your close rate, times your average ticket. For a shop missing 60 calls a month with a 30% close rate and a $400 ticket, the loss is roughly $3,100 a month.
Every input except the two percentages comes from your own business, so the result is your number, not a study's. The two percentages are deliberately mid-range: getnextphone's 2026 analysis of 1.45 million calls found 51% of inbound calls are real leads, and the never-call-back figure of up to 85% is the commonly cited ceiling from Invoca and PATLive data — if you want a conservative estimate, use 70% and the loss is still substantial. Here is the worked example:
- Count your missed calls. Check your phone system or call log for last month. Example: 60 missed calls.
- Keep only the real leads. 60 × 0.51 = about 31 genuine leads (the rest are spam, wrong numbers, and existing customers with quick questions).
- Remove the ones who never return. 31 × 0.85 = about 26 leads gone for good.
- Apply your close rate. 26 × 0.30 = about 8 jobs you would have won.
- Apply your average ticket. 8 × $400 = roughly $3,100 per month — about $37,000 a year.
Run it with your real figures. If you do not know your missed-call count, that is the first finding: most phone systems and carriers can report it, and it takes ten minutes to check.
What does it cost by industry?
The cost of a missed call depends on what one job is worth. Industry data puts a missed HVAC call at roughly $1,200 per job, a plumbing call at about $850, and a dental patient at around $850 in lifetime value. At those ticket sizes, even a handful of missed calls a month outweighs the cost of answering them.
Miss rates do not vary as neatly by industry as job values do, so the table below applies the cross-industry unanswered range from the studies above — roughly 28% on the low end to 62% at the strict, voicemail-counts-as-missed high end — to each trade's typical missed-call job value.
| Industry | Miss rate | Cost per missed call |
|---|---|---|
| HVAC | 28–62% of calls not answered live (cross-industry range) | ~$1,200 per missed-call job (ACCA) |
| Plumbing | 28–62% of calls not answered live (cross-industry range) | ~$850 per missed-call job (PHCC contractor data) |
| Dental | 28–62% of calls not answered live (cross-industry range) | ~$850 per patient, lifetime value |
These are averages, and your mileage will vary — a two-truck shop and a twenty-truck operation miss calls for different reasons. The point of the table is scale: when a single missed call carries a four-figure value, you do not need to miss many before it becomes one of the largest invisible costs in the business.
What actually fixes it?
Three things, in order of cost: measure it, call back fast, and make sure every call gets answered by someone or something. Start by pulling your real missed-call count monthly. Then set a callback standard measured in minutes, not days. Finally, cover the gaps — lunch, jobs in progress, after hours — with a person, a service, or an AI receptionist.
Measurement comes first because you cannot fix a number you do not track, and most owners who check are surprised. Fast callbacks come second: with 78% of buyers choosing whoever responds first, a callback in five minutes beats a callback tomorrow, every time. Coverage comes third, and it is where the 42% of calls that arrive outside business hours get handled. That coverage can be a rotating on-call phone, a human answering service, or an AI phone agent that books the job directly into your calendar. The right choice depends on your call volume and ticket size — run the formula above with your numbers and compare it against the cost of each option. For most service businesses, the math is not close.
Frequently asked questions
Is the "62% of calls go unanswered" figure real?
It comes from a real study — 411 Locals tracked 85 businesses for 30 days and found only 37.8% of calls were answered live. But it counts calls that went to voicemail as unanswered, and the sample is small. Larger studies put the figure lower: CallRail's 220,000-business data suggests 28–30%. Quote the range, not just the headline.
How do I find out how many calls my business misses?
Your phone provider or VoIP system almost certainly logs it. Look for calls with no answer, calls that went to voicemail, and abandoned calls, then total them for a full month — including evenings and weekends. If you use a call-tracking tool like CallRail, the report is built in.
Does this apply if most of my calls are existing customers?
Partly. Existing customers are more forgiving and more likely to leave a message or try again. The formula handles this with the 51% lead factor — it assumes about half your inbound calls are real new leads. If your mix skews heavily to existing customers, lower that factor and rerun the math.
Is an answering service or an AI receptionist better?
Both fix the core problem — a human or system actually responding. Human services are warmer on complex calls but cost more per minute and still follow scripts. AI receptionists answer instantly, handle multiple calls at once, work 24/7, and can book directly into your calendar, but need careful setup for edge cases. Many businesses compare both against their missed-call loss first.
What if my missed-call count turns out to be small?
Then you have verified good news with data instead of assuming it. Run the formula anyway — at HVAC or plumbing ticket values, even five missed calls a month can mean several thousand dollars a year. If the number is genuinely negligible, spend nothing and recheck quarterly.

A note on the headline number: the widely shared "62% of small-business calls go unanswered" figure comes from the smallest study cited here and defines a call to voicemail as unanswered, which is why this article leads with the range instead. The largest datasets (CallRail, Invoca) suggest roughly 28–44% of calls are not answered live. Per-business results vary widely with hours, staffing, season, and trade — which is exactly why the formula in this article uses your call volume, your close rate, and your ticket size rather than any study's average.
