How Much Are Missed Calls Costing Your Business? (Formula + Examples)
Short answer: multiply the calls you miss each week by the share that are new customers, your close rate and your average job value, then by 52. For a typical trades business that misses 10 calls a week, the result is often $40,000–$120,000 a year in lost revenue. Most callers who reach voicemail don't leave a message. They call the next business on the list.
Why missed calls cost more than they look
A missed call never appears on an invoice, so it's easy to ignore. Three things make it expensive:
- Callers don't wait. People calling a local business usually have a problem now: a leak, a toothache, a legal deadline. If nobody answers, the next search result is a tap away.
- Voicemail doesn't save the call. One widely cited 411 Locals study found that 62% of calls to small businesses went unanswered. Most of those callers never left a message.
- You paid for the call. If the caller found you through ads, SEO or a referral, a missed call wastes that acquisition cost as well as the job.
The missed-call cost formula
Annual lost revenue =
missed calls per week
× % of those calls that are new business
× your close rate on answered calls
× average job / customer value
× 52Optionally, multiply by lifetime value instead of a single job value if customers come back (dental patients, HVAC maintenance plans, legal clients with repeat matters).
Worked examples
| Business | Missed calls / week | New business % | Close rate | Avg value | Lost per year |
|---|---|---|---|---|---|
| HVAC company | 12 | 60% | 50% | $450 | $84,240 |
| Plumber (solo) | 8 | 70% | 60% | $350 | $61,152 |
| Dental practice | 20 | 30% | 60% | $1,000 (first-year patient value) | $187,200 |
| Personal injury firm | 5 | 40% | 10% | $8,000 (fee per case) | $83,200 |
| Real estate agent | 6 | 50% | 5% | $9,000 (commission) | $70,200 |
These are illustrations, so swap in your own numbers. Even when you halve every assumption, the cost of missed calls usually dwarfs the cost of answering them.
How to find your real missed-call numbers
- Carrier or phone system logs. Most mobile carriers and VoIP systems show missed and unanswered calls. Export a month.
- Count calls that went to voicemail, and how many of those left a message.
- Look at time of day. Missed calls cluster at lunch, early morning, evenings, weekends, and any time you're with a customer.
- Check repeat callers. A number that called twice in ten minutes was someone who really wanted you.
Ways to stop missing calls, compared
| Fix | Cost | Covers after hours? | Handles simultaneous calls? | Books the job? |
|---|---|---|---|---|
| Answer everything yourself | Your time | Only if you never sleep | No | Yes |
| Hire a receptionist | $3,500+/month | No | No | Yes |
| Answering service | $150–$1,500+/month | Yes | Partly | Rarely, usually takes a message |
| Voicemail + callback | Free | No | No | Only if they wait for you |
| AI receptionist | $0–$300/month | Yes | Yes | Yes, on your calendar |
An AI receptionist answers every call on the first ring, day or night, including when five people call at once. It answers questions about your services and prices, and books the appointment on your Google or Outlook calendar while the caller is still on the line. You get a transcript of every call, and calls that need you can be transferred to your phone.

Don't forget the calls you do answer
Missed inbound calls are half the problem. The other half is slow follow-up on leads that come in through your website. Research published in Harvard Business Review found that companies contacting online leads within an hour were nearly seven times more likely to qualify them than those who waited longer.

Frequently asked questions
How much revenue does a missed call cost?
It depends on your job value and close rate. Use this formula: missed calls per week × percentage that are new business × close rate × average job value × 52. For a trades business, one missed call is often worth $150–$500 in expected revenue. For dental and legal practices it is often far more.
What percentage of business calls go unanswered?
A widely cited 411 Locals study found that 62% of calls to small businesses went unanswered. Your own rate depends on staffing and hours. Check your carrier's missed-call log for a month to measure it.
Do customers leave voicemails?
Most don't. When a local business doesn't answer, callers usually hang up and call a competitor rather than leave a message and wait.
What's the cheapest way to stop missing calls?
An AI receptionist is usually the cheapest option that covers nights, weekends and simultaneous calls. Plans start free. A typical small business pays $60–$300 a month including usage, far less than one or two lost jobs.
