Missed calls cost trade businesses real money — every unanswered call is a job that might go to a competitor. Enter your weekly calls, how many go unanswered, and your average job value to see what those missed calls add up to over a year.
Estimate your missed-call cost
How to read your result
A shop gets 40 calls a week and misses 20% — that’s 8 missed calls a week. If 40% of those would have booked, that’s about 3.2 bookings a week, or roughly 166 a year over 52 working weeks.
At an average job value of $350, the illustrative estimate is about $58,000 of annual revenue at risk. Only you know your real booking rate — this shows what your own numbers imply.
Which trades is this for?
Any trade that lives on inbound calls. When new customers reach out by phone, every missed call is a job that might go to someone else.
- HVAC & plumbing: emergency calls go to whoever picks up.
- Electrical: after-hours calls that won’t wait until morning.
- Cleaning: new-customer enquiries that book with whoever responds.
- Landscaping: seasonal leads calling several companies at once.
Assumptions & limits
- A “missed call” means a missed lead. Calls from family or existing customers with questions don’t count — only calls that could have turned into new jobs.
- Repeat callers count more than once. Someone who rings twice is two missed calls in this math.
- Booking rate is the share of answered calls that turn into booked work, not your overall close rate on quotes or follow-ups.
- One average job value hides your mix. If you do $150 drain calls and $2,000 installs, run the calculator once per job type.
- This is revenue at risk, not profit — it doesn’t subtract labour, materials, fuel or overhead for the jobs you didn’t do. Use it to decide whether an answering service, a new hire or a better phone setup is worth the cost.
Common questions
How many calls am I actually missing?
Check your phone records and compare them to your booked jobs. Most owners are surprised by how many calls go unanswered — especially during jobs, after hours and on weekends.
What booking rate should I use?
Your best guess is fine to start. If you book about half the new-customer calls you answer, use 50%. You can adjust it later once you track your numbers.
Isn’t this just guesswork?
It’s an estimate, but it’s based on your own numbers — calls missed, average job value and booking rate. It’s meant to show the scale of the problem, not an exact dollar figure. Even a rough number can tell you whether fixing missed calls is worth the investment.
What can I do about missed calls?
Options include an answering service, a dedicated office person or a call-back system for after-hours. Compare the monthly cost of the fix against the monthly cost of missed calls — the calculator shows you the other side of that equation.
