Most owners underestimate their missed-call rate. The phone rings, nobody picks up, the caller leaves a voicemail — or doesn't. The voicemails get called back eventually, some of them convert, and the ones that don't just disappear into whatever the owner does next. The money leaks quietly. This is how to tell if it's happening in your business.
The diagnostic list
Run these five questions. If three or more are yes, missed calls are almost certainly leaking meaningful revenue in your business:
- Do you regularly see caller-ID numbers from calls you didn't answer, with no voicemail?
- Do callers tell you, "I tried to reach you earlier" when you do connect?
- Is your voicemail box full more than once a week?
- Do you have a visible pattern of missed calls in the evening, weekends, or during busy daytime stretches?
- Do you notice new-customer inquiries sometimes mention, "I called a few places today"?
What the numbers usually look like
Across DMV home services, healthcare practices, and law firms, pre-deployment missed-call rates sit in these bands:
- Home services: 20-32%
- Healthcare: 18-25%
- Law firms: significant after-hours leakage — variable depending on intake posture
If your practice is in one of those ranges and you don't have a structured after-hours response system, you are almost certainly losing revenue you could reasonably recover.
How to measure your own rate
Your phone system already has the data. Most modern phones log inbound calls even when they aren't answered. Pull a 30-day report. The number of missed calls divided by total inbound calls is your rate. Compare against the bands above. If your phone system doesn't produce that report, the number is almost always worse than you think.
What to do with the number
If the rate is under 10%, you're fine — don't solve a non-problem. If it's 10-15%, look at scheduling and coverage before you invest in technology. If it's above 15%, a voice AI agent is almost always the highest-ROI first deployment.
Assigning a revenue number to it
Take your average closed-matter or booked-appointment value, multiply by the fraction of missed calls that would have converted, multiply by missed calls per month. The math usually makes itself clear fast. For the full framing, see AI voice agents for DMV practices.
