The Cost of Missed Calls (And How to Recover That Revenue)

You might not think a few missed calls matter, but they add up dramatically.

The math

Average missed calls per week: 15. Average value of a new customer: $1,200. Conversion rate from answered call to customer: 25%. That's 15 × 52 × 0.25 × $1,200 = $23,400 lost per year.

Adjust the assumptions and the picture barely improves. Even at 5 missed calls a week and a $500 customer value, the annual loss clears $3,000. For higher-ticket trades like roofing or HVAC replacements, the number climbs well past the illustration above.

Hidden costs

Beyond the immediate loss, there's brand damage: callers who get voicemail often perceive your business as unresponsive and move on.

Independent data shows how unforgiving callers are. Invoca's analysis of more than 60 million calls found that 27% of home-services calls go unanswered, and fewer than 3% of those callers leave a voicemail. Most people who reach your voicemail do not leave a message and do not call back. They call the next business.

Missed calls also compound through referrals. A customer who never reached you cannot recommend you. None of that loss shows up in a call log, which is why missed-call revenue stays invisible until someone measures it.

Why after hours hurts most

ServiceTitan's platform data shows booking rates dropping from 61% during peak hours to 21% after 6 p.m. Evening and weekend callers are often the most urgent and the most valuable, and they are the ones most businesses miss.

How AI recovers this

Nora answers 100% of calls, qualifies on the spot, and books the meeting. Capturing every lead instead of a fraction of them changes the math entirely.

At $297 CAD/month flat, recovering even one or two average customers per month covers the cost many times over. Nora also removes the ceiling on your marketing: every dollar spent on SEO and ads works harder when the calls it generates actually get answered.
