Every call your dental clinic does not answer is a person who wanted a cleaning, a root canal consultation or a braces enquiry, and who may now be calling the next clinic on the list.
This post gives you a simple calculator in rupees that turns your own missed-call count into a monthly number, so you can judge what a missed call alert service, or something that actually answers the phone, is worth to you. Every input is yours to fill in. The examples are labelled as examples and are not industry averages.
What is the formula for the cost of a missed call?
The cost is not "missed calls multiplied by your fee". Many missed calls are not new patients, and not every new patient would have booked. The formula filters those out in three steps, and each step is a number you can measure in your own clinic.
Weekly cost = missed calls per week x share that are new patients x booking rate x average first-visit value
Monthly cost = weekly cost x 4 (use 4.3 if you want to be exact, 4 keeps the sum simple)
Here is what each input means:
- Missed calls per week: people who called and were not answered, counting each person once, not each ring.
- Share that are new patients: of those people, how many were new enquiries, not existing patients, suppliers or wrong numbers.
- Booking rate: of the new-patient callers, the share who would book an appointment if someone had answered.
- Average first-visit value: the rupees you collect from a new patient's first visit.
For example, take a clinic with 25 missed calls a week, 40% of them new patients, 30% of those who would book, and Rs 2,000 collected on a first visit. Then 25 x 0.40 = 10 new-patient callers, 10 x 0.30 = 3 bookings lost a week, and 3 x Rs 2,000 = Rs 6,000 a week. Over a four-week month that is Rs 24,000. These figures are an example, not a measurement of any real clinic.
How do you count your own missed calls?
Your phone already keeps most of the evidence. Count for two weeks, not one, because a single week can be distorted by a festival, a rainy day or a school holiday. Then divide by two for a weekly figure.
- Open the call history on every phone that patients can reach. List the incoming calls that went unanswered. If you use a landline, a cloud phone or an exchange, ask your phone provider for its call report.
- Give the front desk a tally sheet with columns for date, time, number, type (new patient, existing patient, supplier, wrong number) and whether it was called back.
- Count people, not attempts. If the same number rang three times in ten minutes, that is one missed call.
- Remove calls you can identify as not patients, such as your lab, your dental supplier or a known sales number. Do not remove a call just because it is inconvenient.
- Note the hour. Missed calls often cluster around lunch, evenings, Sundays or when every chair is busy. That pattern tells you where to fix things first.
The tally sheet also gives you the second input. Divide the new-patient missed calls by all missed calls and you have your own "share that are new patients".
The sheet holds patients' phone numbers, so keep it with the front desk. India's Digital Personal Data Protection Act, 2023 sets out notice and consent rules for personal data, so check what applies to how your clinic stores and uses these numbers.
How do you find your booking rate and first-visit value?
Nobody can give you these two numbers except your own clinic, and no published average should replace them. Both take a week of simple tracking.
Booking rate. For one week, call back or WhatsApp every missed number that looks like a new patient, and record how many book. A sample message you can adapt:
Hello, this is [clinic name]. We missed your call earlier. Would you like to book an appointment? Reply with a day and time that suits you.
This is a sample for you to edit. Treat the result as your own observation. Callers who were answered on the spot may book at a different rate, and you will only know that by tracking it, so start with the rate you measured and show yourself a low and a high case.
Average first-visit value. Take what you collected last month from new patients on their first visit and divide by the number of new patients. Use the amount you actually collected for the consultation, X-ray or cleaning, not the treatment plan you hope they accept later. If you want to include follow-up treatment, run it as a separate second line so you never mix the two.
A short checklist for both numbers:
- Track the booking rate for one full week before you trust it.
- Record every new-patient miss you call back, and whether that person books.
- Use what you collected at the first visit, not the treatment plan.
- Keep follow-up treatment on its own second line.
What do three example clinics lose a month?
The table below uses three made-up clinics so you can see how the numbers move. They are examples for practice, not averages and not data from any real clinic. Replace every figure with your own.
| Example clinic | Missed calls a week | New-patient share | Would book | First-visit value | Bookings lost a month | Monthly cost |
|---|---|---|---|---|---|---|
| Quiet clinic | 10 | 40% | 25% | Rs 1,000 | 4 | Rs 4,000 |
| Medium clinic | 25 | 40% | 30% | Rs 2,000 | 12 | Rs 24,000 |
| Busy clinic | 60 | 30% | 20% | Rs 3,000 | 14.4 | Rs 43,200 |
Look at what moves the result. The busy clinic has the lowest new-patient share and booking rate, yet it loses the most, because of its missed-call count and its first-visit value. Change one input at a time on your own numbers to see which one matters most for you. A figure like Rs 43,200 shows what is at stake. It is not a promise of what any service will win back, because no service turns every missed call into a booking.
What does a missed call alert service tell you, and what does it not?
In the plain sense used here, a missed call alert service is anything that tells you after the fact that a call went unanswered: a notification, an SMS or a daily list. It is useful because it makes the problem visible. The tally sheet above is a manual version of the same idea.
What an alert does not do is talk to the caller. By the time you see it, the caller has already hung up, and the next step depends on someone at the clinic having a free minute to call back. Compare the two approaches:
- Alert only: you learn about the missed call, then someone calls back. It works when staff have spare time soon after the alert. It struggles when every chair is busy, which is when most calls are missed.
- Answering: the caller speaks to someone straight away, hears your timings and gets booked while still on the line. Nothing waits for a call-back.
If you are comparing alert providers, ask how quickly the alert arrives, who receives it, whether it records the time and number, and what the caller hears meanwhile. Anssay sits on the answering side. Its home page says it answers your missed calls and WhatsApp messages, books appointments and reminds customers, in English, Tamil and Hindi, and it is built for appointment businesses such as clinics, dental practices and others. Its Voice plan also lists a missed-call WhatsApp follow-up with callback.
How many first visits does it take to cover a monthly plan?
Another way to use your first-visit value is to ask how many first visits would cover a monthly fee. The pricing page lists Voice at Rs 4,999 a month and Voice + Chat at Rs 6,999 a month, both excluding 18% GST. With GST that is Rs 5,899 and Rs 8,259 a month.
| First-visit value (example) | First visits to cover Voice, Rs 5,899 | First visits to cover Voice + Chat, Rs 8,259 |
|---|---|---|
| Rs 1,000 | 6 | 9 |
| Rs 2,000 | 3 | 5 |
| Rs 3,000 | 2 | 3 |
Each figure is the plan cost with GST divided by the first-visit value, rounded up to a whole visit.
Three cautions apply. This compares the fee with first visits only, and says nothing about how many bookings any service will win for you. The Voice plan includes 300 call minutes a month, so check that against your call volume, since extra minutes are charged. And the Chat plan, at Rs 2,999 excluding GST, covers WhatsApp and website chat but not phone calls, so for missed calls the Voice plans are the relevant ones.
How can you cut missed calls without new software?
Some fixes cost nothing and are worth doing whether or not you ever use a service. Start with the hours your tally sheet flagged.
- Name a phone owner for the busiest hours. One person whose first job is the phone, not whoever is free.
- Stagger lunch breaks so the front desk is never empty.
- Set a call-back rule. Every missed number gets a call or a message within a time you choose, and the sheet shows whether it happened.
- Divert on busy or no answer to a second phone, so a call is not left ringing out when the line is busy. Airtel's page on call diversion describes diverting calls when your phone is busy, unanswered or unreachable.
- Record a clear after-hours greeting with your timings and a WhatsApp number, so callers have a next step.
- Print your WhatsApp number on the clinic board and your profiles, so patients have a second route to you. The WhatsApp Business app lets a business greet people and reply when away.
None of these answer a call at 9 pm, but they shrink the pile you have to call back.
Which mistakes make the number wrong?
A calculator is only as honest as its inputs. Watch for these:
- Counting every ring. Three attempts from one patient is one missed call.
- Counting existing patients and suppliers as lost new patients.
- Using a best-case booking rate. Use the rate you measured, then show a lower case next to it.
- Using the treatment plan value instead of what you collect at the first visit.
- Mixing revenue with profit. The calculator gives rupees collected. Your own margin is lower, so decide which one you are comparing against a fee.
- Using one week. A holiday week or a camp week gives a number you cannot repeat.
What should you do this week?
You can have your own answer in two weeks with no software at all.
- Start the tally sheet today at the front desk.
- After one week, start calling or messaging every new-patient miss and note who books.
- Work out your first-visit value from last month's collections.
- Fill the formula with your own numbers and calculate a low case and a high case.
- Decide your own threshold. If the monthly cost is smaller than the effort and fees involved, a call-back rule may be enough. If it is larger, and your staff cannot call back in time, test an answering service.
Where does Anssay fit in?
If your tally shows that missed calls are rare, or your front desk calls back quickly, you may not need anything beyond the call-back rule above. If it shows a steady pile of new-patient calls going unanswered during busy hours and evenings, then answering them is the part an alert cannot do, and that is what Anssay is built for.
It answers calls and WhatsApp messages in English, Tamil and Hindi, books into your calendar, and hands anything tricky to you with context, including prices, complaints and new questions. It only answers from what you have confirmed, and it does not give medical advice. You can try it on your own calls with the 14-day free trial, no card needed, and compare what it books against your own calculator.

A quick way to decide:
- Missed calls are rare, or your front desk calls back quickly: the call-back rule may be enough.
- New-patient calls pile up in busy hours and evenings: answering them is the part an alert cannot do.
- You want to test it: use the 14-day free trial and compare what it books against your own calculator.
