How Much Do Missed Calls Cost a Small Business?
By the Vocavant team · Updated 7 November 2026
The cost of missed calls is: calls you miss × the share of those callers who would have become customers × your average customer value. For many small businesses that adds up to thousands every month, because people who call are usually ready to buy.
Why are missed calls so expensive?
A phone call is one of the strongest signs that someone wants to buy now. When nobody answers, most callers don't leave a voicemail; they ring the next business on Google. You lose the customer you already paid to attract through your website, ads, reviews or word of mouth.
How do I calculate my own cost?
You need four numbers, all from your own business:
- Calls per week: check your phone bill or call log.
- Share of calls missed: include calls while you're busy, on a job, after hours or already on the line.
- Share of missed callers who would have become customers: think about how many callers usually book.
- Average value of a new customer or job.
Monthly loss = calls per week × share missed × share who would book × average value × 4.33 weeks.
What does a worked example look like?
Take a business with these numbers (an example, not real data):
- 60 calls a week
- 20% missed, so 12 missed calls a week
- 30% of those would have booked, so about 3.6 lost customers a week
- $250 average job value
That's about $900 a week, or roughly $3,900 a month and $46,800 a year. Try your own numbers in the missed call cost calculator.
Which calls are most likely to be missed?
- While you're working: under a sink, with a patient, mid-service.
- After hours: evenings and weekends, when customers finally have time to call.
- At busy times: two calls at once, and one goes unanswered.
How can I stop losing those calls?
You can hire a receptionist, use an answering service, or use an AI receptionist that answers every call 24/7 and books customers in. We compare all three in AI receptionist vs answering service vs hiring a receptionist.
