A missed call rarely shows up on a report. The caller dials the next company on the list, and the job you paid to win goes to someone else.
This post shows how to work out the cost of missed calls for your business with your own numbers, where calls usually slip through, and what to change first.
Why a missed call costs more than it looks
A homeowner with a dead AC or a leaking pipe rarely calls just one company. Whoever answers and offers a time usually gets the job.
You also paid for that call. Ads, your website, your Google profile and your truck wraps all exist to make the phone ring.
If you run Google Local Services Ads, you may pay for the miss too. Google charges for a missed call during your business hours when the caller stays on the line for more than 20 seconds, and says missed calls may negatively affect your responsiveness, one of the inputs to how your ads rank.
Work out your own number
You don't need an industry average. You need four numbers from your own business, and you probably have them already.
- Missed calls per week. Pull them from your phone system or carrier call log. Count calls that rang out or went to voicemail, minus spam.
- Share that were real new jobs. Listen to the voicemails or call a sample back.
- Your booking rate. Of new-customer calls you do answer, how many book?
- Average job value. Use your average ticket, not your biggest install.
Multiply the four together for lost revenue per week. Multiply by 52 for the year.
An example with round numbers
These numbers are made up to show the math. Swap in yours.
- 12 missed calls a week
- Half are real new-customer jobs: 6
- You book half of those when you answer: 3 jobs
- Average ticket of $400: $1,200 a week, or $62,400 a year

Where calls usually slip through
- Techs on a job. The person who answers is often the person holding the wrench.
- Lunch, drive time and school runs. Short gaps add up over a week.
- After hours and weekends. Emergencies don't keep office hours.
- Busy season. When every line rings at once, the overflow goes to voicemail.
- Voicemail itself. Many callers hang up without leaving a message, so you never know they called.
What to fix first
Measure for one normal week
Log every missed call and the time it came in. Patterns show up fast, often around lunch, late afternoon and evenings.
Call back in minutes, not hours
A fast callback still saves many missed calls. In research published in Harvard Business Review, firms that contacted an online lead within an hour were nearly seven times as likely to qualify it as firms that waited an hour longer.
Cover the gaps you found
If the misses cluster at lunch, stagger breaks. If they cluster after 6 pm, you need after-hours coverage: an answering service, an on-call rotation, or an AI receptionist.
Check the calls you do answer
An answered call that ends with "we'll call you back with a time" can be lost as easily as a missed one. Offer a slot before you hang up.
Give people a way to book without calling
Some customers would rather pick a time than wait on hold. Put a booking link on your website, Google profile and social bios so they can book a slot while your team is busy. See how online booking works.
Where Cindy fits
Cindy is an AI receptionist that answers your business line 24/7. She answers questions about your services, shares your own estimates when asked about price, and books the job on your real calendar.
If a caller wants a person, she transfers the call, or takes a callback request when nobody picks up. Every call is recorded with a transcript, so you can see what was said and whether it booked.
