How much do missed calls cost a service business?
If you're reading this, you probably suspect the number is bigger than it feels. Below are worked examples you can check, what public data does and doesn't tell you, the options for answering more calls, and a free calculator for your own numbers.
Cost of a single missed call — worked examples
The dollar cost of one missed call depends on ticket size and booking rate. The rows below are arithmetic on example inputs, not figures for any trade. A locksmith, plumber, HVAC, garage door, towing or restoration business uses the same math with its own ticket and booking rate.
| Example | Example ticket | Example booking rate | Cost per missed call | Per year at 10 misses a week |
|---|---|---|---|---|
| Example 1: smaller ticket | $100 | 50% | $50 | $26,000 |
| Example 2: the calculator's starting values | $215 | 55% | $118.25 | $61,490 |
| Example 3: larger ticket | $500 | 60% | $300 | $156,000 |
| Example 4: large job | $2,000 | 40% | $800 | $416,000 |
Every input in this table is an example, not an industry average or a measured result. Cost per missed call = example booking rate × example ticket. The yearly column assumes 10 missed calls a week (520 a year). Replace all three with your own numbers.
Why the cost is higher than the headline number
The revenue from the job is only part of it. Here's what else a missed call can cost.
First, the caller often doesn't wait. For time-sensitive service work — a lockout, a burst pipe, a broken AC on a July afternoon — the caller needs the problem solved now, and the next Google listing is one tap away. Calling back is harder than it sounds: in a 2020 Pew Research Center survey, 67% of U.S. adults said their general practice is not to answer calls from unknown numbers but to check voicemail if one is left. When you call back, leave a message that says who you are and what you can do.
Second, you may already have paid for the call. If they found you through Google Local Services, Google Ads, a lead-gen site, or a Yelp listing, the cost of that lead or click may already be spent. Google's Local Services help page on leads says “With Local Services Ads, you pay for valid leads,” and counts a call you missed during your business hours as a valid lead when the customer stays on the line for more than 20 seconds.
Third, missed calls can hurt how your ads rank. Google's Local Services ad-ranking page lists your responsiveness to customer inquiries among its ranking factors and says plainly: “Missed calls may negatively affect your responsiveness.”
Fourth, you can lose the customer's later work. A lockout customer who would have come back for a rekey or a spare key goes to whoever answered. Your invoices show how often customers return. Example: if one in four first-time customers later books a $150 job, add $37.50 to the cost of each missed first call.
Eight in 10 U.S. adults say they don't generally answer their cellphone when an unknown number calls, and 67% say their general practice is not to answer an unknown number but to check voicemail if one is left.
The anatomy of a missed call
Here's an illustrative example (not measured timings) of how a missed lockout call can unfold from the caller's side:
Caller locked out of a 2019 Silverado on a freeway shoulder. Googles "automotive locksmith near me." Four results appear.
Taps the first result. Phone rings. Seven rings → voicemail greeting ("leave a message after the beep").
Hangs up without leaving a message. Taps the second result. Phone rings. Voicemail.
Third result. Voicemail.
Fourth result. Someone picks up. Quick quote, ETA given. Caller books.
You wake up the next morning to a missed call from a number you don't recognize. The caller was helped by the fourth locksmith hours ago.
In this example, the caller goes from "I'm locked out" to "someone is coming" in under a minute. The three shops that missed the call never had a chance.
How to stop missing calls
Four options, with what each costs and what it does with the call. TheKeyBot makes an AI receptionist, so weigh our description of option 1 accordingly.
AI receptionist
TheKeyBot Lite includes 100 calls a month, then 50¢/min, and sends each message to your phone for you to call back. Core includes 500 AI minutes, then 45¢/min, and quotes from your price sheet, books on your calendar, notifies the closest available technician and texts a payment link for a deposit. Other AI receptionists price and work differently.
Live answering service
Booking, payments or Spanish can be add-ons, and agents can only quote what your script and price sheet tell them. Ask how quickly messages reach you at night.
Hire an in-house receptionist
One person takes one call at a time, and nights and weekends need more staff or a second option.
Do nothing / voicemail-only
What it costs depends on how many callers leave a message and how fast you call back. Your call log can tell you both.
Published prices for live and AI answering services, with links to each vendor's own page, are in our after-hours answering service guide. For a sense of in-house cost, the Bureau of Labor Statistics puts the 2025 median pay for receptionists at $18.27 an hour, before benefits.
