Missed-call cost calculator
What does a ringing phone nobody answers actually cost? Enter five numbers and get an answer you can check.
The short answer
How do you calculate the cost of a missed call?
Multiply four numbers: how many calls come in per day, what share goes unanswered, how many working days are in the month, and what share of those unanswered callers would have become customers — then multiply by the average value of a customer. That is the monthly loss. Most businesses are surprised not by the percentage but by the absolute figure: eight unanswered calls a day at an average customer value of 600 runs to tens of thousands a year, whatever your currency.
Lost per year
$190,080
$15,840 per month
- Unanswered calls per month
- 176
- Customers lost per month
- 26
This is a plain multiplication of the numbers you entered — no hidden coefficients. It does not assume an AI agent saves 100% of those calls: some callers hang up regardless, and some need a person. Read the figure as the ceiling of the opportunity, not a promise.
