About $430,315 of revenue leaks out of the phone every year
That's roughly $180,732 in gross profit, and you already paid about $25,704 in marketing to generate the leads you never answered. No new advertising fixes this. Answering discipline, a five-minute callback standard and a written follow-up sequence do — and they cost almost nothing.

What this number actually tells you
This is the most expensive problem in small business and the one owners are least willing to look at. You spend money to make the phone ring, then nobody answers it, or somebody answers and never calls back, or a quote goes out and nothing happens after that.
Three leaks: leads never answered, leads answered too slowly to win, and quoted work with no follow-up. Each has a measurable cost, and together they're usually larger than the entire marketing budget.
The fix isn't more leads. It's a phone standard, a response-time standard and a written follow-up sequence. That's it. It's free and almost nobody does it.
How the math works
- 01Missed lead loss = annual leads × missed % × close rate × average ticket.
- 02Wasted marketing = missed leads × cost per lead — money already spent on leads you never touched.
- 03Slow-response loss = annual leads × slow % × close-rate drop × average ticket.
- 04Follow-up loss = quoted leads × no-follow-up % × close-rate lift from follow-up × average ticket.
- 05Gross profit lost = revenue lost × gross margin %.
What to do with the answer
- Pull your call logs for last month and count unanswered and unreturned calls. Do not estimate — count.
- Set a five-minute callback standard for every inbound lead during business hours, and measure it.
- Build a fixed follow-up sequence on every quote: day 1, day 3, day 7, day 14. Most lost quotes were never followed up once.
- Fix this before increasing ad spend. Buying more leads for a broken phone process is the most expensive mistake in small business marketing.

How much does a missed call cost a small business?
The full lead value plus the acquisition cost already spent. If your average job is $1,800, you close 40%, and your margin is 42%, an unanswered lead costs about $300 in gross profit — plus the $85 you paid to generate it.
How fast do I need to respond to a lead?
Minutes, not hours. Response inside five minutes dramatically outperforms an hour, and after 24 hours most leads have hired someone else. Speed is usually a bigger factor in close rate than price.
Does following up on quotes actually work?
Yes, and it's the most reliably ignored money in a small business. A structured sequence over two weeks commonly adds 5–15 points of close rate on quoted work, because most competitors quote once and go quiet.
