The math, honestly

How much do missed calls cost a small business?

The cost is your own three numbers multiplied together: calls you miss per week, the share of answered calls that become customers, and what an average customer is worth. Most owners have never run that multiplication — and it's routinely a painful number, because callers who reach voicemail typically don't leave a message; they dial the next business on the list. Run your numbers below. No email required, nothing to download — the point is that you know the number.

Calls you miss per week (after-hours, mid-job, lunch — be honest)

Of calls you DO answer, what % become customers?

Average value of one customer (first job only — lifetime makes it worse)

Revenue walking to a competitor, at your numbers:

$2,598 / month

$31,176 / year

Assumes missed callers close at the same rate as answered ones would have — if anything, urgent callers close higher. Math: missed/week × 4.33 weeks × close rate × value.

Why this matters

The call you miss goes somewhere.

For service businesses, a large share of new-customer calls arrive outside office hours or while everyone on the team is mid-job. Those callers rarely wait: the common pattern is voicemail, hang-up, next result. That means the real competition for the job often isn’t who’s better — it’s who answered.

That’s the business case for an AI receptionist that picks up in seconds, every hour of every day — and it’s why we built one into the AI office we engineer for clients. Whether the calculator’s number justifies one for you is exactly what it exists to show.
