- A widely cited 411 Locals study found 62% of calls to small businesses went unanswered.
- Speed decides outcomes: contacting leads within an hour made qualification ~7× more likely (HBR).
- The cost of missed calls = missed calls × % that were real opportunities × close rate × average job value.
- After-hours and peak-time calls are the biggest leak for owner-operated businesses.
- Missed-call text-back and AI answering are the two fastest fixes.
For service businesses, the phone is still where a large share of high-intent customers make contact. Someone with a burst pipe, a broken AC unit or a legal problem doesn’t fill in a form and wait, they call, and if nobody answers, they call someone else. Here’s what the data says about missed calls, and how to calculate what they cost you.
How many calls go unanswered?
The exact share varies by industry, season and staffing, and this study is several years old, but in our experience auditing call logs, owner-operated businesses routinely miss a meaningful share of calls during busy periods, lunch and after hours. The best source is your own phone system: most providers show answered versus missed calls.
Why callers don’t wait
Missed calls hurt more than missed emails because phone callers are usually further along in the decision and have more alternatives one tap away. Research on lead response shows how steeply the odds fall with delay:
Those studies focus on web leads, but the lesson carries over to calls: the first business to respond has a structural advantage.
How to calculate the cost of missed calls
You don’t need industry averages, you need four numbers from your own business:
- Missed calls per month (from your phone system).
- Opportunity rate, share of those that were genuine new-business inquiries (not spam or existing customers).
- Close rate, share of answered opportunities that become customers.
- Average job or customer value.
Example: 120 missed calls × 40% opportunities × 30% close rate × $450 average job ≈ $6,480 per month, or roughly $78,000 a year.

Where missed calls come from
| When | Why calls are missed | Best fix |
|---|---|---|
| After hours & weekends | Nobody is there | AI receptionist or phone answering |
| Peak times | All lines busy | AI overflow answering |
| On job sites | Owner or tech can’t pick up | Missed-call text-back + AI answering |
| Lunch & breaks | Front desk away | Conditional forwarding to AI |
| Seasonal surges | Volume exceeds staff | AI answering scales instantly |
Five ways to stop losing missed calls
- Missed-call text-back: an automatic SMS to every missed caller, "Sorry we missed you, how can we help?", keeps the conversation alive. It’s a standard GoHighLevel automation.
- AI phone answering: AI answering picks up on the first ring, captures details and books jobs.
- Overflow forwarding: your team answers first; the AI takes calls you can’t.
- Callback SLAs: if a human must return the call, set a target (e.g. 5 minutes) and track it.
- Follow-up sequences: an AI follow-up system keeps chasing leads who went quiet.
