What a missed call really costs, and how to count yours
Search for the cost of a missed call and you will find confident percentages from surveys you cannot check. We are not going to add one. The true cost of a missed call at your business depends on who was calling, what they wanted, and what you would have earned from them, and none of that is in a survey. The good news is that you can measure it yourself in two weeks with a notebook. This playbook shows how.
Why you should not borrow a statistic
A borrowed number is either too scary or too comforting, and you cannot tell which. A dentist's missed call is often a new patient worth years of visits. A pizzeria's missed call is one dinner. A law firm's missed call may be a case or may be a cold sales call. Averaging them tells you nothing about your Tuesday.
Counting your own is also cheap. It takes a tally sheet, a fortnight, and one honest afternoon of callbacks. At the end you will have a number you can defend to yourself, your partner, or your accountant, and a plan that fits it.
Two weeks of counting
Step one: count the misses
For two normal weeks, record every call you did not answer live. Your phone system or mobile call history has most of it: unanswered calls, calls that went to voicemail, calls that hit an engaged line. If you have a phone menu, add callers who hung up inside it. Write down the time of day and the day of the week next to each one. Two weeks is enough to see the pattern: lunchtimes, Monday mornings, the hour after you close.
Step two: find out what they wanted
Within a day, call back every number you can and simply ask. Sort each call into one of four boxes: a new customer, an existing customer, a supplier or sales call, and unknown. Note whether the new customers still wanted the job when you reached them, and whether you won it. That last column is the one people skip, and it is the one that turns a tally into money.
The sum
Now you have four numbers of your own, and the formula is short.
- Misses per week: the tally from step one, divided by two.
- Share that were new enquiries: the new-customer box divided by the total you reached.
- Your win rate: from your own records, how many enquiries become paying jobs.
- Average job value: what a typical first job is worth, from your invoices.
Multiply the four together and you have the revenue at risk each week. Multiply by 52 for the year. Here is the shape with made-up numbers, not real ones: 10 misses a week, half of them new enquiries, a win rate of one in three, and a first job worth 300 gives 10 times 0.5 times 0.33 times 300, which is about 500 a week. Put your own figures in and the answer will be different. That is the point.
The costs the formula misses
The sum only counts revenue you can see. Several costs hide behind it. Existing customers who could not reach you and quietly went elsewhere. The evening you spend returning calls, which is unpaid time or family time. The interruptions on the days you did answer, when you stopped a job to say "can I call you back". The review that mentions "impossible to get hold of". And the call you answered while distracted, which was technically not missed but was not handled either.
You cannot put clean numbers on all of these. You can note them in the margin of the tally sheet, and you can ask three regular customers one question: "When you call us, how does it usually go?" Their answer is data too.
What to do with the number
Once you have a weekly figure, the decision is arithmetic. Any fix that costs less per week than the revenue at risk is worth trying, and the cheapest fix that works is the right one. Sometimes that is forwarding the phone to a colleague at lunchtime. Sometimes it is a rota. Sometimes it is a person or a service that answers for you. Sometimes it is a voice agent that picks up, books, takes a message, and hands the urgent calls to you. Here is a plain guide to that option, and here is what it costs.
Whatever you choose, count again a month later with the same tally sheet. If the misses dropped and the callbacks column improved, keep it. If not, you have lost a month and learned something, which is cheaper than most alternatives.
Where NordTell fits
NordTell is one of the fixes on that list: an agent that answers when you cannot, says it is an AI, books or takes a message, and always keeps a way to a person. It writes a summary and an outcome for every call, which makes the second count much easier than the first. You can build and test it in the browser for free before you connect a number.
