What one missed call actually costs your business

Every page selling an answering service opens with a statistic. Some percentage of callers never call back, some other percentage of business goes to whoever answers first. The numbers are usually unsourced, usually a decade old, and always suspiciously round.

Here is the alternative: work it out with your own numbers. It takes four figures you already know and about two minutes, and the answer is far more persuasive than anyone else's statistic, because it is yours.

The arithmetic

cost of a missed call = average job value
                      x close rate on answered calls
                      x share of missed callers who do not come back

Multiply that by how many calls you miss in a month and you have the monthly number. That is the whole model. The rest of this page is about getting each input honest.

1. Average job value

Not your best job. The median of what actually comes in from a phone enquiry. If you are an HVAC contractor whose phone brings a mix of diagnostics, repairs and the occasional system replacement, the replacements distort the mean badly. Take the middle.

If you do not know it, take last month's revenue from phone-originated jobs and divide by the number of those jobs.

2. Close rate on answered calls

Of the calls you actually pick up, what share becomes work? For most trades this sits somewhere between a quarter and two thirds, and you probably have a feel for it. Use your own figure, not a flattering one, and if your book is genuinely full, use the rate at which you convert calls you want.

3. The share who never come back

This is the input everyone quotes and nobody measures. You can measure it in one afternoon.

Take last month's missed calls from your phone log. For each unique number, check whether that number appears again in the log, or in your invoices, in the following week. The share that never appears again is the share you lost. Do it over thirty missed calls and you will have a number for your business that is worth more than any survey.

Two things reliably move it. Urgency: nobody with water on the floor waits for a callback. And whether the caller found you through a search result with three other contractors listed underneath.

4. Missed calls per month

Read it off the phone, not off memory. Include every unanswered ring, not just the ones that left voicemail, because the caller who leaves no message is the one this whole exercise is about.

A worked example

An electrician with a median job of $340, who closes half of the calls he answers, who finds that 6 in 10 missed callers never return, and whose log shows 41 missed calls last month:

340 x 0.5 x 0.6      = $102 per missed call
102 x 41             = $4,182 per month

Whether that number is worth acting on is a judgement about his business, not about a statistic. But now it is a real number, and it can be compared against the cost of doing something about it, which is the only comparison that matters.

The four things that change the answer

How fast the phone gets answered, not whether it eventually does. A callback two hours later competes against three contractors who answered live. A callback ten minutes later usually does not.

What happens on the calls you do answer. A call answered by someone driving, on a job site, with no way to write anything down, is not fully answered. Details get lost and the follow-up never happens.

The share of your missed calls that were worth answering. Be honest here: it deflates the number. Spam, suppliers, and enquiries for work you would never take are all in that log. If a third of your missed calls were never going to be jobs, cut the result by a third. A model you trust is worth more than a big number.

When the calls arrive. Most trades find their missed calls cluster into a few hours: early morning, late afternoon, and the entire weekend. That clustering is what makes the problem fixable, because it means you are not trying to staff a phone around the clock, only during the windows where nobody can pick up.

What the arithmetic does not say

It does not say you need to answer every call yourself. Owner-answered calls are expensive in the way that matters most: they interrupt the work you are being paid for. A model that says missed calls cost $4,000 a month does not automatically say "answer them all". It says: this problem is worth $4,000 a month of attention, so what is the cheapest way to convert it?

The options are the usual four. Hire someone. Use a human answering service and pay by the minute. Use an AI receptionist. Or accept the loss, which is a legitimate decision if the number comes out small.

The choice between them is a separate question, and we wrote about it in AI receptionist vs answering service.

Measure it again afterwards

Whatever you do, run the same count a month later: missed calls, and the share of those numbers that never appear again. If the second number does not move, the fix did not work, whoever sold it to you.

That is also the honest test of an AI receptionist, including ours. If you want to hear what your callers would hear, Heyly answers our own line on +1 208 504 3639 all day and all night.

FAQ

Is there a real statistic for how many callers never call back?

There are several, and they disagree, mostly because they measure different industries and different decades. That is why this page shows you how to measure your own instead of adding one more number to the pile.

Do missed calls matter if I am already fully booked?

Less, but not zero. A full book today is not a full book in six weeks, and the caller you never answered will not think of you when the book empties. Capture, then schedule further out.

Should I count spam calls as missed calls?

No. Filter them out before you do the arithmetic, or the model will overstate the loss and you will stop trusting it.

What is the fastest way to reduce missed calls without hiring?

Conditional call forwarding to something that answers. Your phone rings first, and anything you cannot take goes to a service instead of to voicemail. The carrier codes are here, and the setup takes about five minutes.
