What the loss meter tells you
The loss meter answers one question: if some of the calls to your business go unanswered, roughly how much revenue walks away, and what would answering more of them be worth? It is built for owners and managers of businesses that live on inbound calls, such as trades, clinics, service shops, professional offices and property managers.
You enter a few facts about your own phone line and the tool multiplies them. Results update live as you move a slider or type in a number box. The inputs are:
- Calls per workday
- The share of calls that go unanswered
- The share of those unanswered calls that are new customer inquiries
- The share of new inquiries that would have booked
- The average value of one new customer
- Working days per month
- A what-if slider: the share of missed calls you could answer instead
From those inputs you see missed calls per month, new customers lost per month, revenue lost per month and per year, and the revenue you could recover per year if you answered the what-if share of missed calls instead.
A leak tank shows the monthly revenue your call flow could bring, with the leaked part draining away. A twelve-month cumulative line shows how the figure builds up over a year. When you are done you can download a share card as an image, share it, or copy a plain-text summary for an email or a team chat.
Nothing you type is sent anywhere. The tool also counts towards the free Lab Pass, and that progress is kept only in your own browser. Other free tools are listed in the AI tools lab.
How to use it in two minutes
Get a real call count
Look at a recent stretch in your phone provider's call log, your voicemail inbox or your front desk notes. A rough count from memory works for a first pass, but a log is better because the missed-call share drives everything else.
Enter calls and the unanswered share
Set calls per workday and the share nobody picked up. Count calls that rang out, went to an empty voicemail, or ended while the caller waited.
Keep only new inquiries
Existing customers, suppliers, spam and wrong numbers are not lost sales in this tool. Set the new-inquiry share to the part of unanswered calls that came from people asking about your service for the first time.
Use honest booking and value numbers
Use your real booking rate on inquiries you did answer, and a customer value you could defend with invoices, such as typical first-year revenue from a new customer.
Try the what-if last
Move the what-if slider to the share of missed calls you could realistically answer, with a schedule change, extra staff or an AI receptionist. Keep it modest, then copy or download the result.
How the numbers work
The tool chains simple multiplications, so you can check any result with a pencil. In words:
- Calls per month is calls per workday times working days per month.
- Potential monthly revenue, the full tank, is calls per month times the share that are new inquiries, times the share that would book, times the average value of one new customer.
- Lost revenue per month, the leaked part, is the potential times the unanswered share. Lost revenue per year is that figure times twelve.
- Missed calls per month is calls per month times the unanswered share. New customers lost per month is the missed calls times the new-inquiry share, times the booking share.
- Recoverable revenue is the lost revenue times the what-if share, shown per year.
Because everything is multiplied, the order does not matter, and halving any one input halves the lost revenue. That makes the result easy to sanity check: if it looks too big, find the input you are least sure of and test a lower value.
Other limits to keep in mind:
- Calls outside your opening hours count only if you include them in calls per workday.
- One average value covers every customer and every inquiry is treated alike. If your jobs vary widely, run the tool twice, once with a low value and once with a high one, and read the range.
- The tool counts revenue, not profit, and the cost of fixing the problem is not in it. For payback, use the AI agent ROI calculator.
How to read your result
Read the numbers from the top down, and check each one against something you can see in your own records before you trust the next.
| Result | What it means | How to check it |
|---|---|---|
| Missed calls per month | Calls nobody answered in a month | Count them in your call log or voicemail inbox |
| New customers lost per month | Missed calls that were new inquiries and would have booked | Compare with your booking rate on inquiries you did answer |
| Revenue lost per month and per year | Lost customers times the average value of one customer | Check the average value against real invoices |
| Recoverable revenue per year | The share of the loss you would win back in the what-if | Test it with a small pilot, not by assumption |
Two mistakes are common. One is entering every unanswered call as a lost customer. The other is using the value of a single job when most customers come back. Run a cautious version and a generous version, and treat the gap between them as the honest answer.
If the new customers lost per month figure is less than one, read it as one lost customer every few months. That is a smaller problem than a daily leak and may not justify a new system.
What to do about missed calls
Missed calls have a few ordinary fixes. Which one fits depends on why calls are missed: nobody is free to answer, nobody covers after hours, or calls arrive in bursts. Here is a general comparison, with no prices or percentages because they depend on your business.
| Option | Good at | Weak at | Watch out for |
|---|---|---|---|
| Staffing and schedule changes | A person who knows your business answers | Cost grows with every extra hour covered, and breaks, sick days and busy peaks still leave gaps | Hiring for a peak that lasts only part of the day |
| Voicemail with callback rules | Simple and low effort | Many callers will not leave a message, and callbacks depend on discipline | A callback window nobody tracks |
| Human answering service | A live voice outside your hours | Generic scripts, and the agents see only what you give them | Notes that never reach your calendar or CRM |
| AI receptionist | Can answer several calls at once at any hour, handle routine questions and booking, and write a note | Unusual, emotional or urgent calls, and anything not covered by approved answers | Wrong answers, recording disclosure and urgent calls that must reach a person |
Often the answer is a mix: people during your open hours, an AI receptionist for overflow and after hours, and written rules for what always goes to a person. An AI receptionist is software that answers the call, handles routine questions and booking from content you approved, captures lead details and passes urgent or sensitive calls to a person with a written note. We design, connect and run these on accounts you own. Read more on the AI receptionist page, and on the AI voice agents page for the technology behind the voice.
Our agents ask for approval on risky steps, log every action, use least-privilege access with a dedicated service account for each agent, and can be switched off. Work starts with a request, a short call and a written scope, and a pilot comes before rollout.
When this tool is not a good fit
The loss meter is a rough tool for one specific problem. Skip it, or read the result with extra care, in these cases:
- Your business does not depend on inbound calls. If most new work arrives by online form, chat or email, missed messages matter more than missed calls. See AI customer service.
- Most of your calls come from existing customers, suppliers or your own crews. Those calls matter, but this tool counts only new inquiries as lost sales.
- You cannot say roughly how many calls go unanswered. Count them for a couple of weeks first, then come back.
- Each sale is large and slow, such as a long project or a regulated service. One lost inquiry may be worth far more or far less than the average, so use ranges rather than one value.
- A missed call can be a safety problem. Revenue is the wrong measure there, so plan the emergency route with a person first.
- You want a forecast or a budget. This is an estimate to start a conversation, and a pilot is the only way to measure what answering more calls is really worth.
What to prepare if you want a scope from us
If the result shows a leak worth fixing, you do not need a finished plan to talk to us. A short description is enough, and it helps to bring these:
- The summary from the tool, copied into the request form
- A rough call log or voicemail count for a recent stretch
- Your phone system, calendar and CRM or booking tool
- Your opening hours, and when calls are missed: lunch, after hours, busy mornings
- The calls that must always reach a person, and who approves new answers
