Missed Calls at an Auto Repair Shop: What They Cost

Every shop misses calls. The question is how many, and what they're worth. Marchex, a call analytics company, reports that among large multi-location auto service operators, up to 21% of calls went unanswered, dropped or mishandled, and that even the best locations still missed close to 10%.

Your shop's number may be higher or lower, and it's easy to find out. This guide gives a formula to turn missed calls into lost revenue, a worked example using average repair order data from Tekmetric's Shop Index, a way to measure your own missed-call rate from your phone logs, and the fixes, from cheapest to most complete.

The short answer

Marchex, which analyzes calls for large multi-location auto service operators, found up to 21% of calls went unanswered, dropped or mishandled, and calls a missed-call rate at or below 10% healthy. To price your own: missed calls per week × share that are new work × your booking rate × your average repair order.

Key takeaways

• Marchex reports missed-call rates of up to 21% at large auto service operators; it calls 10% or less healthy.
• Lost revenue per week = missed calls × share wanting new work × booking rate × average repair order.
• With illustrative inputs and Tekmetric's average ARO, 20 missed calls a week is roughly $2,800 a week in repair orders not written.
• Measure your own rate from your phone system's call log: unanswered and voicemail calls during open hours divided by all inbound calls.
• Fixes range from free (call forwarding) to an answering service or AI receptionist; a missed-call text-back is a cheap middle step.

Disclosure: we make BayRobin, an AI receptionist and front office for independent repair shops, and show where it fits. Everything here works without it. Figures from other companies come from their public pages, checked in October 2026 and linked at the end.

How many calls does an auto repair shop miss?

The best published figure comes from Marchex's analysis of calls to large multi-location auto service operators. It found:

• Up to 21% of customer calls went unanswered, dropped or mishandled, depending on the operator and market.
• Even top-performing locations still missed close to 10% of calls.
• Appointment rates on answered calls ranged from single digits to over 60% within the same network.
• Marchex treats a missed-call rate at or below 10% as healthy.

Two caveats. These are big chains, not independent shops, and Marchex doesn't publish a sample size or date range. An independent shop with one service writer may miss more during the morning rush and fewer the rest of the day. Treat 10% as a goal and 20% as a warning sign, then measure your own.

How do you calculate what missed calls cost your shop?

Use four numbers:

Weekly lost revenue = missed calls per week × share of those calls that want new work × your booking rate on answered calls × your average repair order (ARO)

• Missed calls per week: from your phone log (see the next section).
• Share wanting new work: not every missed call is a lost job. Some are "is my car ready?", vendors or spam. Listen to a sample, or start with 30% to 40% as an assumption.
• Booking rate: of calls you do answer that ask about work, how many book? Marchex saw anywhere from single digits to over 60%.
• ARO: use your own. If you don't have it, Tekmetric's Shop Index (from its own customers' shops, data through June 2026) shows a national average ARO of $704.25 and a median of $649.88.

Worked example with illustrative inputs, not data from any shop:

Some missed callers will try again, so you won't lose all of this. If you think half call back, halve it. And this is revenue, not profit: multiply by your gross margin to see what it means for the bottom line. Even the conservative column usually pays for whatever fix you choose many times over, and it doesn't count the future visits a new customer would have made. For the upside, put your car count and ARO into the free shop revenue calculator and see what one more booked car a day adds over a month and a year.

How do you measure your own missed-call rate?

Most business phone systems and VoIP providers let you export a call log. Pull two to four weeks, then:

1. Keep only inbound calls to your main shop number.
2. Split them into open hours and after hours. Measure each separately.
3. During open hours, count calls that weren't answered by a person: unanswered, abandoned on hold and sent to voicemail.
4. Remove obvious repeats: the same number calling three times in five minutes is one missed caller, not three.
5. Divide missed calls by total inbound calls. That's your missed-call rate.
6. Group missed calls by hour of the day and day of the week to see when they happen.

If your system can't export a log, put a tally sheet by each phone for one week and ask the team to mark every call they couldn't get to. It's rough, but it beats guessing.

Then check the other side: of the missed callers who were new numbers, how many show up as customers later? If few do, you're losing them.

When do shops miss the most calls?

The pattern in most shops is predictable. The phone rings hardest when the service writer is busiest:

• The morning drop-off rush, when the counter has a line.
• Lunch, if one person covers the phone.
• Late afternoon pickups, when customers are paying and asking questions.
• Saturdays, if you're open with a lighter crew.
• Evenings and weekends, when you're closed. The after-hours guide covers these.

Knowing your worst hours lets you fix those hours first, which is cheaper than fixing all of them.

How do you stop missing calls?

Pick the cheapest option that covers your worst hours, then add more if the numbers say so.

Our answering service comparison lists published prices, and the service advisor vs AI receptionist guide compares the cost of hiring with both.

For a missed-call text, get the customer's consent before ongoing texting, always identify the shop and honor STOP replies. Check with your phone or texting provider, or your counsel, about TCPA and 10DLC registration specifics.

What should you do about the calls you've already missed?

Call back fast. A callback within minutes catches people before they've booked elsewhere. Make it a rule: every missed call from an unknown number gets a call or text back within 15 minutes during open hours, and first thing the next morning for after-hours calls.

"Hi, this is Dana from Main Street Auto. I saw we missed a call from this number a few minutes ago. Sorry about that. How can I help?"

Then track it. A weekly line on your whiteboard (calls in, calls missed, missed-call rate) keeps the number in front of the team, alongside your other shop KPIs.

Frequently asked questions

What percentage of calls do auto repair shops miss?

Marchex reports that large multi-location auto service operators miss, drop or mishandle up to 21% of calls, with top locations still near 10%. It considers 10% or less healthy. Independent shops vary widely, so measure your own from your phone log.

How much does a missed call cost an auto repair shop?

Multiply the chance the caller wanted new work by your booking rate and your average repair order. With 40% wanting work, a 50% booking rate and Tekmetric's $704.25 national average ARO, each missed call is worth about $141 in repair orders, before any repeat visits.

How do I find out how many calls my shop misses?

Export two to four weeks of inbound calls from your phone system, separate open hours from after hours, count unanswered, abandoned and voicemail calls, remove repeat calls from the same number, and divide by total inbound calls.

Do missed callers call back?

Some do and many don't; it varies by shop and by how urgent the problem is. Calling or texting them back within minutes recovers more of them, which is why a fast callback rule or a missed-call text helps.

What's the cheapest way to stop missing calls at a repair shop?

Call forwarding or a rollover to a second phone costs little or nothing, and a missed-call text-back is usually inexpensive. Neither answers every call, so shops with a high missed-call rate often add an answering service or an AI receptionist for rush hours and after hours.

Where BayRobin fits

BayRobin is one way to cover the gaps: its missed-call text-back texts missed callers within a minute, and its AI receptionist answers around the clock and books routine work into open times. Measure your missed-call rate first, so you can see whether it changes. BayRobin is free until your first 10 booked jobs, no card up front. Start free or see pricing.
