Every missed call is worth $287. Here's the math.

I've been running Delgado HVAC in Austin for eleven years. I thought I had a pretty good handle on what a missed call costs: a service call here, a repair job there. Maybe $200 on a slow day, $600 on a good one.

I was wrong by a factor of three.

Working with the Calling Matrix team, we ran the actual numbers — not just the immediate job value, but the full picture of what a missed call costs when you account for lost lifetime value and referrals. The answer came out to $287 per missed call, blended across 1,400 shops in their network.

Here's exactly how we got there.

Component 1: The immediate job ($192 in lost revenue)

The average home service job across all categories is $347. When a caller reaches voicemail instead of a live voice, 92% don't call back. Of the 8% who do, roughly half end up booking elsewhere anyway.

So the expected revenue from a missed call — based on actual callback and conversion rates — is approximately $347 × 0.08 × 0.50 = $14. Compare that to the expected revenue from an answered call: $347 × 0.55 conversion = $191. Difference: $177 per missed call in immediate revenue.

Component 2: Lifetime value loss ($72)

A home service customer who books their first job with you has a median lifetime value of $1,840 over 3.2 years — driven by repeat service calls, annual maintenance plans, and system replacements. A customer who called you but ended up booking with a competitor has a LTV of approximately $0 for your business.

Using a 55% first-call conversion rate, each missed call represents a 55% chance at $1,840 in LTV — or $1,012 in expected LTV. Versus near-zero from a voicemail caller. But we discount this heavily because most businesses would have retained those customers imperfectly anyway. The incremental LTV loss from a missed call vs. an answered call comes to approximately $72 when you apply realistic retention curves.

Component 3: Referral loss ($38)

The average home service customer refers 1.4 new customers over their lifetime. Each referral has the same expected LTV. When you lose a customer to a competitor, you lose those referrals too — or rather, your competitor gets them.

Discounted for probability and time, the referral loss per missed call works out to approximately $38.

What this means in practice

Before I started tracking my answer rate, I was missing an estimated 38–42 calls per week — most of them after 6 PM and on weekends. At $287 each, that's over $550,000 per year going to competitors. I didn't feel those losses because I never saw the calls I was missing.

The thing about missed call revenue is that it's invisible. You don't get a notification when someone calls, gets your voicemail, and books with the competitor down the street. You just notice that some weeks are slower than others, and you blame it on seasonality or the economy.

The fastest way to test your real missed call exposure: check your phone system's missed call log for the last 30 days and count calls between 6 PM and 8 AM. Then multiply by $287. Whatever number you get — that's the size of your after-hours opportunity.
