What missed calls really cost a small business (and how to estimate yours)

You’ve probably seen the claim that small businesses miss most of their calls. Here’s where that number comes from, what it does and doesn’t say, and a simple way to work out what missed calls cost you.

Where the “62%” statistic comes from

The figure traces back to a blog post published in January 2016 by 411 Locals, a local marketing company. It reported monitoring calls to 85 businesses in 58 industries for 30 days and found that 37.8% of calls were answered, 37.8% went to voicemail and 24.3% got no response (411 Locals, 2016).

Two honest caveats. First, the 62% counts voicemail as “unanswered”; calls that got no response at all were 24.3%. Second, it’s a small, vendor-run sample from years ago, so treat it as a sign that missed calls are common, not as a measurement of your business. (We found this framing well explained in this fact-check.)

Why speed matters anyway

A widely cited Harvard Business Review study of online sales leads found that companies that tried to contact a lead within an hour were far more likely to qualify that lead than those that waited longer (HBR, “The Short Life of Online Sales Leads,” 2011). That research was about web leads, not phone calls, but the lesson carries over: interest fades fast, and the business that responds first has the advantage.

Estimate your own cost in four numbers

Forget industry averages. Your own numbers are better. You need:

  1. Missed calls per month. Check your phone carrier’s call log, or count for one normal week and multiply by four.
  2. Share that are potential new customers. Not every call is a sale. Exclude spam, vendors and existing customers with quick questions.
  3. How many of those you’d normally win. Of the new-customer calls you do answer, how many become paying jobs?
  4. Value of a typical new customer. Use the average first job, or lifetime value if customers come back.

Missed calls × share that are new customers × win rate × customer value = monthly revenue at risk

A worked example (hypothetical numbers)

Say a plumbing company misses 40 calls a month. Half are potential new jobs (20). It normally wins 1 in 3 of those, about 6–7 jobs. If an average job is $300, that’s roughly $2,000 a month at risk. Not every missed caller is lost for good, since some leave a message or call back, so treat the result as an upper bound and adjust for how many callers usually return.

What to do about it

  • Measure first. Look at when calls are missed: lunch, after hours, busy seasons.
  • Cover the gaps. Options include a shared phone rota, a live answering service, a DIY AI app, or a done-for-you AI receptionist like PickupWave. Our comparison page lays out the trade-offs and prices.
  • Make voicemail better. If you rely on it, tell callers exactly when you’ll call back, and do it.
