What Happens to Missed Calls, and How to Count Your Own

A missed call goes one of four ways: the caller leaves a voicemail, calls back later, texts, or calls someone else. You only see the first three. The fourth never shows up anywhere, which is why missed calls are easy to underestimate. You do not need an industry statistic to size the problem. Your phone provider's call log can tell you how many calls you missed last month, and a simple worksheet turns that into an estimate in dollars.

The Path of a Missed Call

Here is what happens after the phone rings out, in order:

The calls that matter most are often the urgent ones, because urgent callers are the least willing to wait.

Not Every Missed Call Is a Lost Job

Some missed calls are robocalls, sales pitches, wrong numbers or existing customers who will call again anyway. Counting every missed call as lost revenue overstates the problem. Counting none understates it. The worksheet below separates them.

How to Count Your Own Missed Calls

Most business phone providers let you export a call log. Take two normal weeks and mark each unanswered call:

StepWhat to countWhere it comes from
1Unanswered callsCall log: missed, voicemail or no-answer
2Minus spam and repeat numbersUnknown robocallers, the same number five times
3Minus existing customers who called backNumbers you recognize, or that called again within the day
4What is left: possible new workUnknown numbers that never reached you
5Your close rate on new callsOf the new callers you do answer, how many book
6Your average first jobFrom your invoices

Then the estimate is: possible new work × close rate × average first job.

Example only, with made-up inputs: 12 possible new calls missed in two weeks, a 30% close rate and a $400 average first job is 12 × 0.3 × $400 = $1,440 in two weeks. Your numbers will be different. Use yours.

This is an estimate, not a forecast. It leaves out repeat business and referrals, which can make a lost customer worth more, and it assumes missed callers would have closed at the same rate as answered ones, which may not hold.

Four Ways to Catch More of Them

1. Answer more calls yourself

Forward the office line to a cell during jobs, or have one person own the phone. Free, but it pulls someone off the work.

2. Missed call text back

An automatic text to anyone you did not answer, asking what they need. Cheap and fast to set up. It must say how to opt out, and business texting from a regular ten-digit number through software needs carrier registration. Twilio's documentation states that anyone sending SMS over a 10DLC number from an application to the US must register for A2P 10DLC. See our missed call text back guide for contractors.

3. A human answering service

Live receptionists answer in your business name. Entry plans we checked start at $250 to $300 a month. Best when callers need a person. Prices are in the answering service cost guide.

4. An AI answering service

An AI answers every call, takes details and routes urgent ones. Plans we checked run $0 to $500 and up a month. Ours, Front Desk, is $199 a month plus a $349 launch fee for one location: the AI answers first, urgent calls ring your on-call phone, and callers who hang up before giving details get one text back. See AI vs human answering for the trade-offs.

What We Would Do First

Count before you buy anything. If the worksheet says you miss two possible new calls a month, forwarding to a cell may be enough. If it says twenty, the cost of fixing it is easy to justify, whichever option you pick.

Frequently Asked Questions

What happens when a business misses a call?

The caller leaves a voicemail, calls back, texts, or calls another business. You only see the first three. The last one never shows up anywhere except as a missed call in your log.

How do I know how many calls I miss?

Export two weeks of call logs from your phone provider. Count unanswered calls, remove spam and repeat numbers, and remove existing customers who called back. What is left is possible new work.

How much are missed calls costing me?

Multiply your possible new missed calls by your close rate and your average first job. That gives an estimate using your own numbers, which beats any industry average.

What is the cheapest fix for missed calls?

Forwarding calls to a cell is free. A missed call text back is low cost. Answering services, human or AI, cost more but answer the call itself.
