How it is calculated
Missed calls per month = calls per day × open days × share unanswered. Include out-of-hours calls: for a business open 45 hours a week, nobody answers the phone for two thirds of the week.
Customers lost = missed calls × share who would have bought × share who never call back. The second filter is the one that matters: someone who cannot reach you usually does not try again, they call the next result on Google.
Revenue lost = customers lost × average customer value. This is conservative because it only counts the first purchase: it ignores repeat business and referrals.
The defaults are a reasonable estimate for a local service business. Adjust them with real data from your phone system if you have it.
Frequently asked questions
How many calls does a small business typically miss?
Between 20% and 30% in a business with a receptionist, and over 50% in one with nobody dedicated to the phone. Most of them are not peak-hour calls, they are out-of-hours calls: evenings, weekends and public holidays.
Does voicemail solve the problem?
Barely. Most people who reach voicemail hang up without leaving a message, and many of the messages that do get left are returned hours later, when the caller has already booked elsewhere. Voicemail records the loss, it does not prevent it.
How can you reduce missed calls without hiring anyone?
With an AI phone agent that answers every call at once, 24 hours a day, books appointments in your calendar and hands over to a person when needed. It costs a fraction of the annual loss this calculator shows.
