What a missed call actually costs: the math, with sources

Most missed-call statistics online are recycled estimates with no source. This page builds the cost calculation from inputs we measured on live carrier-level traffic, states every sample size, and separates what we know from what we assume.

The formula

Two costs, not one. The revenue term is the callers who never come back. The labor term is the price of saving the ones who do.

The measured inputs

• Missed share: 30.3% of inbound calls went unanswered across our instrumented client teams over 90 days. n = 12,984 calls, carrier-level count. One 22-person B2B team measured 34.7% in a single month. n = 4,398
• Never-return share: 85% of callers who reach no answer do not call back. BT Business research, external. Our data is consistent: without company callbacks, only about a quarter of missed calls would have reconnected through caller persistence alone.
• Callback share: 80.7% of missed calls were followed by a manual callback attempt within 24 hours at our measured teams, with a median 13-minute delay when the connection was re-made. Even so, 13.4% of missed calls never reconnected. n = 3,939 missed-call events, two teams, 90 days
• After-hours share: 8 to 29% of conversations happen on evenings and weekends, when many missed calls are structural: nobody was ever going to answer. across Canarics clients

Close rate and deal value are yours; no vendor can measure them for you.

A worked example

A trade or service business with 400 inbound calls a month, a 15% close rate on new inquiries, and an €800 average deal:

The two costs people forget

Recovery is not free. The optimistic reading of our data is that disciplined teams recover 86.6% of missed calls within 24 hours. The realistic reading is that they pay for it: four of five missed calls become a manual chore, done by the same people whose being busy caused the miss. The callback pile grows exactly when the team is busiest, which is exactly when the calls were missed.

Speed decays value. The median recovered call reconnects after 13 minutes; the ones that take hours land after the caller has already rung the next supplier. And 30.2% of recoveries only happened because the caller tried again, which is loyalty you are spending, not earning.
