How much a missed call really costs (2026)
This is the deep version. The friendly version is at /how-much-do-missed-calls-cost. Here we walk through the math, how the time of day can change the answer, and what public data from Google, Pew Research Center and the Bureau of Labor Statistics does and doesn't tell you. We haven't run a survey or collected a dataset for this page. Dollar figures below are worked examples built from inputs you replace with your own, and every number about the world links to the page that says it.
1. Cost per missed call: worked examples
Cost per missed call is calculated as booking_rate × avg_ticket. Every input in this table is an example, not a trade average or a measured result. The yearly column assumes 10 missed calls a week (520 a year). A locksmith, plumber, HVAC, garage door, towing, restoration or pest control business uses the same math with its own numbers.
| 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 |
How to read this table: the rows are arithmetic on example inputs, not data about any trade. Substitute your own average ticket and your own booking rate from your invoices and call records. Together with the number of calls you miss, those inputs set the answer.
2. The by-hour multiplier
A missed call isn't necessarily worth the same at every hour. If you charge more for nights, weekends or holidays, a call you miss then is worth more. We don't have measured multipliers, so the table shows example values to replace with your own. The simplest way to set them is from your rate card: multiplier = your ticket for that window ÷ your weekday daytime ticket.
Two facts about timing are documented by Google. Its Local Services ad schedule page says the default schedule, “All day”, runs your ad 24 hours a day, 7 days a week, so calls can arrive whenever the ad runs. And its help page on leads says unanswered calls are only charged when they happen during your active ad schedule and within your business hours, so a call you miss during business hours can cost a lead fee (if the caller stays on the line for more than 20 seconds) as well as the job.
| Time window | Example multiplier | What it would represent |
|---|---|---|
| Weekday 8 AM - 5 PM | 1.0× (baseline) | Example baseline: your standard weekday rate. |
| Weekday 5 PM - 9 PM | 1.3× (example) | Example: an evening surcharge on your rate card. |
| Weekday 9 PM - 12 AM | 1.5× (example) | Example: a late-night or emergency rate. |
| Weekday 12 AM - 6 AM | 1.4× (example) | Example: an overnight emergency rate. |
| Weekday 6 AM - 8 AM | 1.1× (example) | Example: a small early-morning surcharge. |
| Saturday all day | 1.2× (example) | Example: a weekend rate. |
| Sunday all day | 1.4× (example) | Example: a higher Sunday rate. |
| Major holidays | 1.7× (example) | Example: a holiday rate. |
These multipliers are examples, not measured coefficients. Apply them to your own baseline cost per missed call. If your after-hours work doesn't carry a premium, set them all to 1.0.
Worked example: weekend automotive lockout
Example baseline cost per missed call: $118 (a $215 ticket × a 55% booking rate, both example inputs).
- Tuesday 2 PM missed call: $118 × 1.0 = $118
- Friday 7 PM missed call: $118 × 1.3 = $153
- Saturday 11 PM missed call: $118 × 1.2 × 1.5 = $212
- Sunday 1 AM missed call: $118 × 1.4 × 1.4 = $231
- July 4th 9 PM missed call: $118 × 1.7 × 1.5 = $301
In this example, the same call is worth between $118 and $301 depending on when it rings, purely because of the example multipliers. With your own rate card the spread could be smaller or larger.
3. The four hidden costs (beyond the headline number)
The dollar amount of one job is the visible cost. There are four more worth counting.
Sunk customer-acquisition cost (CAC)
If the call came through Google LSA, Google Ads, Yelp, Angi, or a lead-gen aggregator, you may have paid for it before it rang. 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, where the customer stays on the line for more than 20 seconds, among them. Worked example with example values: a shop paying $40 a lead that misses 10 such calls in a month has spent $400 on leads that produced no job.
Lifetime-value loss
A customer you never serve can't come back for the rekey, the spare key or the next lockout, and can't refer anyone. We don't know of a reliable published repeat rate for locksmith or other service customers, so take yours from your own invoices. Worked example with example values: if one in four first-time customers later books a $150 job, each missed first call costs another $37.50 in expected future work.
Ranking and responsiveness
Google's Local Services “About ad rankings” page lists your responsiveness to customer inquiries and requests among the factors in how likely your ad is to result in a lead, and says plainly: “Missed calls may negatively affect your responsiveness.” The same page suggests enabling message or booking leads so customers have more ways to reach you, especially on nights and weekends when you can't answer the phone. A missed call can cost some future visibility as well as the job.
Owner / dispatcher burnout
If the owner answers the night line personally, the cost is sleep, family time and next-day attention. It doesn't show up in the formula and we can't put a number on it for you, but it's real. Emergency trades know the pattern: the Bureau of Labor Statistics notes that plumbers are often on call for emergencies, so evening and weekend work is common, and that HVAC technicians may be on call for emergencies too.
4. The anatomy of a missed call (an illustrative example)
An illustrative example, not measured timings, of how a lockout caller can move from shop to shop after realizing they need a locksmith:
Caller realizes they are locked out. Pulls phone, opens Google.
Searches "automotive locksmith near me." Top 3-4 results appear.
Taps first result. Phone rings. Counts 6 rings → voicemail greeting.
Hangs up without leaving a message.
Taps second result. Rings. Voicemail.
Third result. Voicemail.
Fourth result. Live answer. Quote, ETA, booking.
Caller is done. Has hired the fourth shop. The first three are out.
In a July 2020 Pew Research Center survey of 10,211 U.S. adults, eight in 10 said they don't generally answer their cellphone when an unknown number calls, which matters when you call a missed caller back. The popular claim that 80% of callers won't leave a voicemail traces back to a 2014 magazine item that names no study.
5. The math (in plain notation)
Nothing here is hidden. The cost model has six inputs and produces one output; the optional comparison with an answering plan adds two more inputs.
Inputs: calls_per_day (your inbound call count, daily average) work_days_per_month (the days you take calls; example: 26) miss_pct (share of inbound calls unanswered, 0.0 - 1.0) booking_rate (share of answered calls that book, 0.0 - 1.0) avg_ticket (your own average job value, USD) seasonal_uplift (volume bump for a busy month; example: 0.15) Derived: monthly_calls = calls_per_day x work_days_per_month x (1 + seasonal_uplift) missed_calls = monthly_calls x miss_pct lost_bookings = missed_calls x booking_rate lost_revenue_month = lost_bookings x avg_ticket lost_revenue_year = lost_revenue_month x 12 Answering-plan comparison (two more inputs you set): recovery_share (share of lost revenue you'd win back, 0.0 - 1.0; example: 0.9) plan_cost (monthly cost, USD; example: 500, the Core plan's price) recovered_monthly = lost_revenue_month x recovery_share net_monthly_gain = recovered_monthly - plan_cost roi_multiple = net_monthly_gain / plan_cost
Where the 0.9 recovery share comes from
It's an example, not a measurement. We haven't published data on how much missed-call revenue an answering service or AI receptionist wins back, and we don't know of a reliable public source for it. Your booking rate already allows for callers who wouldn't book with anyone; the recovery share covers what the new setup still loses. What drives it:
- Whether the service books on the call or takes a message for a callback (TheKeyBot Lite takes the message and sends it to your phone; Core quotes from your price sheet and books)
- How quickly and how reliably you call back, if the service takes messages
- Callers who want a person, and how you hand those calls off
- Spam and wrong numbers in your call counts, which you can remove before you start
If you're unsure, run the calculator with a lower recovery share and see whether the result still justifies the cost. For the plan cost, use the plan you'd actually buy: TheKeyBot Core is $500 a month with 500 AI minutes included, then 45 cents a minute; Lite is $149 a month with 100 calls included, then 50 cents a minute. Add any overage you expect.
6. Where the numbers come from
Plainly: the dollar figures on this page are worked examples, not measurements. We haven't run a survey or collected a dataset for this page, and you shouldn't treat these tables as one. The pages below are the sources behind each number about the world on this page, and the calculator is where to put your own numbers.
- How leads work: you pay for valid leads, including some calls missed during business hours
- About ad rankings: missed calls may negatively affect your responsiveness
- Ad schedule: the default “All day” schedule runs your ad 24 hours a day, 7 days a week
- Pew Research Center (2020): most Americans don't answer cellphone calls from unknown numbers
- CRM magazine (2014): the earliest source we traced for the “80% won't leave a voicemail” line; it names no study
- Occupational Outlook Handbook: plumbers: often on call for emergencies; evening and weekend work is common
- Occupational Outlook Handbook: HVAC technicians: may be on call for emergencies; irregular schedules in peak seasons
7. What this model deliberately does not cover
For honesty: here are the holes we know about.
- Geography. Nothing here is broken down by city or metro. Tickets and call volumes differ between markets and between shops in the same market (Houston west side vs Houston east side, Brooklyn vs Queens), and nothing here will capture it. Your own call log will.
- Booking rates. The booking rates in the tables are examples, not medians. Yours depends on your pricing, reviews, service area and who answers the phone; measure it from your own answered calls.
- Multi-call buyer journeys. We model cost per missed call. Some buyers call several shops sequentially; the dollar weight of being the second or third unanswered call is different from the first. We have not modeled this rigorously.
- Cross-channel attribution. A caller who found you via Google, also saw your Yelp listing, and previously got an SMS from your remarketing has a different cost-of-miss than a fresh Google LSA caller. The model treats every call the same.
- Trade-specific seasonal patterns. Some trades are busier in some months than others; the BLS notes, for example, that HVAC technicians sometimes work overtime or irregular schedules during peak heating and cooling seasons. The model has a single seasonal-uplift input and no trade-specific seasonal factors.
