The cost of a missed call

How much does a missed call cost your business?

A missed call costs you the expected value of the work you didn’t win. For a business with a £150 average job where about 30% of callers would have booked, that’s roughly £45 per missed call — and it adds up fast. Use the calculator below to see your own number.

How to work out the cost of a missed call

The true cost of a missed call isn’t the call itself — it’s the work you lose because the caller went elsewhere. You can estimate it with three numbers:

Missed calls × conversion rate × average job value = lost revenue

Example: 10 missed calls a week × 30% who would have booked × £150 average job ≈ £450 a week, or about £1,900 a month.

It compounds because of how callers behave. Most won’t leave a voicemail and won’t try again — they ring the next business on the list. And the data on response speed is stark: leads contacted within five minutes are far more likely to convert than those left for even half an hour.

How to stop paying the missed-call tax

You can’t answer every call when you’re on a job, in a chair, or under a car — and you shouldn’t have to pay hundreds a month for a human answering service to cover it. Missed call text-back is the cheap, automatic fix: the moment you miss a call, the caller gets an instant SMS, an AI captures their enquiry, and a lead summary lands on your phone.

For most businesses, recovering a single job pays for the whole month. From £37/month with no contract, it turns the numbers above from a cost into recovered revenue — and it’s a fraction of the price of an answering service.

Cost of a missed call — common questions

It depends on your average job or sale value, but a useful rule of thumb is the expected value of the lost work. If a typical job is worth £150 and around 30% of missed callers would have become customers, each missed call costs roughly £45 in expected lost revenue. Miss ten calls a week and that is over £1,900 a month.

Multiply three things: the number of calls you miss, the share of those callers who would have become paying customers, and your average job or sale value. For example, 10 missed calls a week × 30% conversion × £150 average job ≈ £450 a week, or about £1,900 a month in lost revenue.

A 2024 study of 85 US businesses by 411 Locals found only about 38% of calls were answered by a live person — close to 62% went to voicemail or got no response. See our missed call statistics page for the full, sourced figures.

Research by Dr James Oldroyd (MIT Sloan), reported in Harvard Business Review, found leads contacted within five minutes are 21 times more likely to be qualified than those contacted after 30 minutes. Callers who miss you rarely leave a voicemail or try again — they ring a competitor, so a slow reply usually means a lost job.

The lowest-cost fix is missed call text-back: when a call goes unanswered, an automated SMS is sent to the caller within seconds, an AI captures their enquiry, and a lead summary is sent to you. It recovers callers you would otherwise lose — from £37/month, far less than the value of a single recovered job.
