What does a missed call really cost my business?

A missed call can cost you a lot, or almost nothing. It depends on who was calling and what they did next. So before you do any math, sort your missed calls into two kinds:

1. Calls that cost you nothing. Existing customers who leave a message, suppliers, spam, and new callers who try again later and book.
2. Calls that cost you a job. A new customer who hangs up, calls the next business on the list, and books with them.

Only the second kind costs money. It is worth asking the question behind most lost work: why did that customer choose the other business instead of you? Sometimes the honest answer is that the other business picked up the phone.

How much money am I actually losing when I miss a call?

You can work it out with four numbers from your own business. You will see big industry figures for missed calls online. We don't use them, because we couldn't trace them past a single source. Your own numbers are better anyway, because they describe your business.

Weekly cost = A × B × C × D

With the example numbers: 4 × 0.5 × 0.5 × $400 = $400 a week in lost sales. Over 50 working weeks, that is $20,000 a year.

The example numbers are placeholders, not averages. Put your own in. A shop with $250 jobs that misses two new callers a week gets a very different answer from a shop doing $8,000 jobs.

Two more steps make the number honest:

• Use profit, not just sales. Say you keep about 40 cents of each dollar after materials and labor. Then $20,000 in lost sales is about $8,000 in lost profit. Use your own margin.
• Count repeat customers only if your records show them. If a typical customer comes back two or three times, one lost first call can cost more than one job.

Why does answering the phone make such a difference?

A caller who reaches a person can book right then. A caller who reaches voicemail has to decide whether to wait for you or try someone else.

One owner described this in a 2023 interview. Neel Parekh, founder of the cleaning company MaidThis, told UpFlip that his company closes far more requests when it answers the call than when it doesn't. That is one business's experience, not a rule. But it shows why number C matters so much in the math above.

Large home-service companies watch the same thing closely:

• In a 2021 episode of his podcast, Tommy Mello named booking rate as one of four key numbers he tracks.
• John Wilson, CEO of Wilson Companies, writes that his company aims to book 90% of the leads that come in through its customer service reps.

Those are targets for big companies with full-time phone teams. You don't need their targets. Our reading is simpler: the people who run large shops treat every answered call as money, and they measure it. You can do the same with a notepad.

How do I know if missed calls are costing me customers?

Check these signs:

• ☐
  Your missed-call list shows numbers you don't know, and many of them leave no voicemail.
• ☐
  When you call back, people say "we already found someone."
• ☐
  New-customer calls are steady, but booked jobs from new customers are falling.
• ☐
  Your missed calls bunch up at the same times: on a job, at lunch, after 5pm, or on weekends.
• ☐
  You can't say how many calls you missed last week.

The last sign is the one to fix first. John Wilson's advice is to measure before anything else. He writes that his company answers the phone in about seven seconds and watches that number every week. That is one large company's own target, not a norm. His point is that the first step is to measure your own performance, every week, the same way.

I probably miss three to five calls a week. Is that a big deal?

It depends on how many are new customers and what a job is worth. Here is the same math for two different businesses, each missing three new callers a week, with the same example 50% figures:

Same number of missed calls, ten times the cost. Swap in your own numbers before you decide anything.

What's one missed remodeling lead actually worth?

Remodelers get fewer, bigger jobs, so think per lead instead of per week:

Value of one lead = average job value × share of serious callers who book an estimate × share of estimates you win

Example only: a $30,000 kitchen, 2 in 3 serious callers book an estimate, and you win 1 in 3 estimates. $30,000 × 2/3 × 1/3 ≈ $6,700 in expected sales per lead. If that homeowner books the next remodeler because you were up a ladder, that is roughly what the missed call cost you.

Are most missed calls from people ready to book, or just shopping around?

You may have seen a claim that most calls to trades businesses come from people ready to book. We couldn't verify where that figure comes from, so we don't repeat it.

Your own phone can answer this. For two weeks, write down what each new caller wanted, from their voicemail or when you call back: book a job, get a price, or ask a question. That tells you how many missed calls were real jobs in your trade. It is more useful than anyone else's average.

What does a missed call cost a law firm or a restaurant?

The same method works with different words:

• Law or accounting firm: missed calls a week from new prospects × share who hire another firm × share of consultations that become clients × average fees from a new client in the first year.
• Restaurant during the dinner rush: calls missed during the rush × share of those guests who order somewhere else × average takeout order. Example only: 10 missed calls × 0.5 × $40 = $200 a night. If those guests are usually repeat customers, the real cost is higher.

When is a missed call not worth fixing yet?

Sometimes the honest answer is "not much." If you are booked solid for weeks, an extra caller may be someone you couldn't serve anyway. John Wilson said on his podcast that nine times out of 10, a home service business does not have a leads problem. In his view, scheduling and capacity are often the real limits. Fix those first.

The math also gives a small number when most of your callers are existing customers who always leave a message, or when nearly all your work comes from referrals who will wait for you. That is a useful answer too. It means your money is better spent somewhere else.

What should I do with the number?

Write it down. Then compare it with what it would cost to answer more calls: forwarding calls to someone else, an answering service, an automatic text when you miss a call, or a part-time person. If a fix costs less than your number, it is worth trying. If it costs more, it isn't, whatever the person selling it says.
