A missed call does not cost you $1,200

Every vendor selling call handling to a home service contractor quotes some version of the same line: a missed call costs you around $1,200. It is on landing pages, in cold emails and in a great many LinkedIn posts.

It is the wrong number, and it is wrong in a specific and checkable way.

The arithmetic is not complicated and that is rather the point. Anybody quoting the job value as the call value has either not done it or has done it and preferred the bigger number.

The second number is worse

The companion claim is how many calls get missed, and here the published figures are so far apart that no single one of them should be repeated at all.

• Published missed-call rates for this kind of business run from roughly 27% to 62%, a factor of 2.3 between the low and high figures.
• Every publisher in that range sells call handling software, which is the product the number argues for.
• None of the ranges we traced published a sample you could inspect alongside the headline percentage.

A factor of 2.3 is not a measurement, it is a spread. If a supplier quotes you a decimal place inside that spread, they are quoting a marketing figure to somebody who owns the actual phone.

What we say instead, and why it works better

Say the smaller number and show the arithmetic. In our experience of building the pitch both ways, being the first person in the room to correct the inflated figure is worth considerably more than the inflated figure was. The owner has heard $1,200 three times this quarter. They have never once heard somebody take it apart.

And then run it on their numbers rather than on anybody's benchmark:

1. Pull last peak month's inbound contacts from the phone system. Not an estimate, the actual log.
2. Count how many were abandoned, or reached voicemail and were never returned the same day.
3. Multiply by your booking rate and your average ticket, both of which you already know.
4. For the trades where a proportion of those calls would have been a large replacement or install job, apply your own conversion rate on that share separately, because the expected value there is very different.

The figure that comes out is the recurring cost of the current response gap, in your business, with a denominator you can point at. It is usually smaller than the number on the landing page and considerably more persuasive, because it is the only one that survives being checked.

One honest limitation. Every number in that calculation is yours, which means the quality of the answer depends entirely on the quality of your call logging. If nobody has ever counted abandoned calls, the first useful thing to build is not a response system. It is the counting.
