What do missed service calls cost your store?

Enter your own numbers. Two starting values are public averages and two are examples, and each field says which. Nothing is behind a form, and the arithmetic is shown.

ExampleExample value. Replace it with your phone system’s count of unanswered and after-hours calls.

173 missed calls × 50% wanted an appointment × 68% did not call back × $494 a repair order.

This is the size of the problem on your inputs. It is not a forecast of what we would recover, and it is not a measurement of your store.

The five inputs

Where each number comes from, and where to find yours.

Service calls your store misses a week
Your phone system or carrier report: unanswered calls, abandoned calls and calls after closing on the service line. The starting value of 40 is an example, not an average.
Share who wanted an appointment
Not every caller wants to book. Some ask about status, hours or parts. Your service manager can estimate this from a week of calls. The starting value of 50% is an example.
Share who do not call back
68% of callers who reach voicemail do not call back, according to Marchex. That figure is for voicemail across the businesses in its study, not for your store.
Average customer-pay repair order
$494 per customer-pay repair order at the average franchised dealership (NADA, 2025). Use the figure from your own financial statement.
Repair orders a month
About 1,350 repair orders a month at the average franchised dealership (NADA, 2025). It is used only to show the lost appointments as a share of your volume.

The arithmetic. Missed calls a week × 52 ÷ 12 gives missed calls a month. Multiply by the share who wanted an appointment, then by the share who do not call back, to get appointments that did not happen. Multiply by your repair-order value for the monthly figure.

Questions and answers

Before you rely on the number.

Is this a forecast of what you would recover for my store?
No. It is the size of the problem on the numbers you enter. It does not predict how much of it we would recover.
Where do the starting values come from?
Two are public averages: about 1,350 repair orders a month and $494 per customer-pay repair order (NADA, 2025), and 68% of voicemail callers not calling back (Marchex). The other two, 40 missed calls a week and 50% wanting an appointment, are examples so that the calculator shows a result. Replace all five with your own.
How do I find how many calls my store misses?
Most phone systems and carriers report unanswered and abandoned calls by line and by hour. If yours does not, we can make one call to your service line after closing and tell you what a caller hears. Request a free phone check.
Do you keep the numbers I enter?
We log the five numbers with an anonymous browser identifier, the same way we log page views, so that we can see whether the calculator is used. We do not ask for your name or your store here.
