How Much Do Missed Calls Cost a Service Business?
How much do missed calls cost a service business? Use this simple formula, see worked examples and learn the options for answering every call.
Short answer: to work out what missed calls cost you, multiply the calls you miss each month by the share of those callers who would have booked, then by your average job value. A business that misses 30 calls a month, would have booked a third of them and earns $450 per job is losing about $4,500 a month.
The formula
Monthly cost = missed calls × booking rate × average job value
- Missed calls: check your phone system’s call log for unanswered calls.
- Booking rate: the share of answered calls that turn into booked jobs today.
- Average job value: your typical invoice for a first job.

Worked examples
| Missed calls / month | Booking rate | Job value | Lost per month | Lost per year |
|---|---|---|---|---|
| 15 | 30% | $300 | $1,350 | $16,200 |
| 30 | 33% | $450 | $4,455 | $53,460 |
| 50 | 40% | $800 | $16,000 | $192,000 |
These figures only count the first job. Repeat customers and referrals make the real loss bigger.
When calls get missed
- While you or your crew are on a job
- Evenings, weekends and holidays
- During lunch and busy mornings
- When two calls come in at once
Why voicemail does not fix it
Many callers do not leave a message. They hang up and call the next business on the list. By the time you call back, the job may already be booked elsewhere.
Ways to stop missing calls
- Text back missed callers automatically within a minute.
- Use an answering service for overflow and after hours.
- Use an AI receptionist that answers 24/7, books jobs and sends you a summary. Read how an AI receptionist works.

Frequently asked questions
How do I find my missed-call rate?
Your phone provider or call tracking tool usually shows answered and unanswered calls. Look at a full month to get a fair number.
What booking rate should I use?
Use your own. If you are not sure, track it for two weeks: how many answered new-customer calls became booked jobs.
Are all missed calls lost jobs?
No. Some are spam or existing customers. That is why the formula uses a booking rate instead of counting every call.
