A missed call costs you the job it would have booked. Not a national average, and not a statistic from a vendor's brochure. It costs the value of that work, multiplied by how many of those calls ring out while you are on a job. The arithmetic is short:
Monthly loss = weekly calls × the share that goes unanswered × your close rate × your average job value × 4.33
Take a tree company that fields 30 calls a week. Forty percent go unanswered — the crew is up a tree and the phone is in the truck — which is 12 missed calls. At a 30 percent close rate, those 12 calls were 3.6 jobs. At a $1,200 average job, that is $4,320 a week. Multiplied by 4.33, it is $18,705.60 a month, and more than $224,000 a year, leaking out of one phone.
Your four inputs will be different. That is the point of this page. Below: where the famous numbers actually come from, what the better data says, the same math worked for six trades, and how to run it on your own call log.
The $126,000 figure, examined
If you have read anything about missed calls, you have seen the claim that a small business loses $126,000 a year to them. The figure is real, in the sense that it was published: it comes from Invoca, the call-tracking company, in 2022. What it is not is a measurement of your business. It is an average drawn from the companies in Invoca's data, repeated since then by hundreds of vendor blogs, usually with the source, the year, and the sample quietly removed.
The companion number in nearly every one of those articles is that 62 percent of calls to small businesses go unanswered. Traced back, that figure rests on a study from January 2016 covering just 85 businesses, circulated by the directory company 411 Locals. Eighty-five businesses, a decade ago, is a thin foundation for a number that now appears in thousands of sales pages.
None of this means missed calls are cheap. It means a single national number, in either direction, is a poor substitute for your call log. The honest answer is the formula above, with your inputs in it.
What the better data says
The more careful measurements point the same direction as the slogans, with wider variation than the slogans admit:
- About 48 percent of home-service calls never reach a person, in Invoca's call-tracking data. Nearly half the demand a trade business generates ends at a ringing phone.
- Up to 62 percent of calls go unanswered at peak times and after hours, in SearchLight's benchmark of 888 contractors, which also valued a lead at about $416 in paid work. Note the difference from the myth: this 62 percent describes the worst windows of the day, not the whole day.
- About 85 percent of callers who do not reach you never call back. A missed call is rarely postponed business. It is business handed to the next company on the list.
- Fewer than 3 percent leave a voicemail. Voicemail is not a safety net. Almost nobody uses it.
- A missed call can now bill you directly. Since October 1, 2026, Google's Local Services Ads can charge for a business-hours call that rings unanswered for more than 20 seconds. The call books nothing, and you may still pay for it.
The call-behavior figures in this section are drawn from Invoca's published call data and SearchLight's benchmark of 888 contractors, as reviewed in The Agency's research in October 2026.
The cost, trade by trade
One call profile, applied evenly so the trades can be compared: 25 calls a week, 40 percent unanswered — ten missed calls — and a 30 percent close rate. That is three lost jobs a week in every row. Only the job value changes.
| Trade | Average job value | Lost jobs per week | Lost per month | Lost per year |
|---|---|---|---|---|
| Tree service | $1,200 | 3 | $15,588 | $187,056 |
| Septic service | $1,800 | 3 | $23,382 | $280,584 |
| Concrete lifting | $1,800 | 3 | $23,382 | $280,584 |
| Crawl space and waterproofing | $5,800 | 3 | $75,342 | $904,104 |
| HVAC, service and replacement blended (example) | $850 | 3 | $11,041.50 | $132,498 |
| General contractor and remodeler | $4,500 | 3 | $58,455 | $701,460 |
Three lost jobs a week sounds manageable until it is multiplied by a $5,800 crawl-space job, at which point it is more than $900,000 a year of demand that phoned in and got no answer. The job values are mid-range examples for each trade — a removal with stump grinding and haul-away runs higher, a pumping route runs lower — and the call profile is deliberately plain. The next section replaces every assumption with your own numbers.
Run your own numbers
The formula takes four inputs, and you already have most of them in writing:
- Weekly calls. Add up the inbound calls on last month's phone bill or call log and divide by 4.33. Count every ring, including the ones nobody answered. The bill already does.
- The share unanswered. The calls that arrived while you were on a job, at lunch, or after hours, plus the ones that simply rang out. If your phone system cannot report this, start with 40 percent, marked plainly as an estimate, and replace it the first month you can measure it.
- Close rate. Of the calls you do answer, the share that become paid work. Use last quarter's jobs divided by answered calls, not your best month.
- Average job value. Last quarter's revenue divided by the jobs completed.
Multiply in order: weekly calls × unanswered share × close rate × average job value × 4.33. The result is not a scare figure. It is the size of the hole, measured with your own tape.
Questions owners ask
How many calls does a small business miss?
More than most owners expect. Invoca's call data puts the share of home-service calls that never reach a person at about 48 percent, and SearchLight's benchmark of 888 contractors found up to 62 percent unanswered during peak and after-hours windows. A business where the owner answers the phone between jobs should assume it sits at the high end of that range until its own call log says otherwise.
Do callers leave a voicemail?
Almost never. Fewer than 3 percent of callers who reach voicemail leave a message. The rest hang up, and about 85 percent of them never call back.
Is the $126,000 figure real?
It is a real published number — Invoca, 2022 — but it is an average across the businesses in one company's data, not a property of small business in general. Quoted without its source, year, and sample, it says nothing about a specific shop. A business fielding ten calls a week lands far below it. The tree company in the example at the top of this page lands far above it. Your call log settles the question.
What percentage of missed callers call back?
About 15 percent. The commonly cited figure is that roughly 85 percent of callers who fail to reach a business never try again. They book with whichever competitor answers first.
What does it cost to fix?
At almost every trade's numbers, far less than the problem. Human answering services generally charge by the minute or by the call, and commonly run to a few hundred dollars a month at small-business volumes. AI phone systems run from tens of dollars a month for a plan you set up yourself to a one-time custom build trained on your business. The Agency works at both ends of that range: The AI Backstop plans start at $34.95 a month, and the Custom AI Phone System is built per business. The audit below is the place to work out which end fits your call volume.
Coverage, not more marketing
Missed calls are a coverage problem. The phone rings at the worst possible moment almost by definition: when you are under a house, up a tree, or halfway through the job the previous caller paid for. Sending more marketing at that problem makes it worse, because every new lead it generates joins the same ringing phone.
The fix is a phone that is always answered. The Agency builds AI phone systems that answer every call in your business's name, around the clock, take the caller's details, and book the job or pass the call through, so the demand you have already earned stops leaking. The AI Backstop covers it on a monthly plan starting at $34.95. The Custom AI Phone System is the built-for-you version, trained on your services, your prices, and your service area.
