What Is Your Overdue Recall List Worth?
Every practice has a list of patients who are due back and have not been contacted. The list is usually longer than anyone expects, and the revenue in it is the easiest revenue a practice will ever earn because the patients already trust you. Enter your own figures to see what is unrealised today and what a higher contact rate would recover.
Pull the overdue count from your practice management system rather than guessing. The contact and attendance rates are the two figures practices most often overestimate, so check them against a recent month if you can.

The ceiling: what the list holds beyond what you earn from it today.
An estimate from the figures you entered, not clinical or financial advice. Results depend on the accuracy of your overdue count and rates, and on having appointment capacity to see the extra patients. Enter aggregate figures only, never patient information.
Reading the Result
The headline figure is not a forecast of what you will earn. It is the gap between what your recall list could produce if every patient were contacted and what it produces at your current contact rate.
Contact rate is the lever
Attendance rate is largely a property of your patients and the clinical need behind the recall. Contact rate is a property of your process. A practice that contacts a third of its overdue list and a practice that contacts most of it can have identical patients and very different revenue, which is why the target slider changes contact rate rather than attendance.
Extra patients, not just extra dollars
The calculator also shows how many additional patients would attend at your target contact rate. That number is the one to check against your available appointment capacity, because a recall campaign that books more patients than you can see turns into a waitlist problem rather than a revenue result.
The clinical case sits alongside the financial one
Overdue recalls are patients who were told to come back and have not. For some of them the delay carries clinical consequence. The revenue figure is a way of making the case for a better process, but the reason to run one is that these patients were meant to be seen.
How the Figures Are Built
Four multiplications. Every input is one your practice management system can report, and nothing else is assumed.
Patients attending today
Overdue patients multiplied by your current contact rate, multiplied by the attendance rate for contacted patients. This is how many of the list you are currently bringing back.
Revenue from recalls today
Patients attending today multiplied by average consult or treatment value, multiplied by visits per recalled patient in the year.
Revenue unrealised
The same calculation with contact rate set to 100 per cent, minus the revenue from recalls today. This is the ceiling of what the list holds, not a target.
Recovered at your target
The calculation run again at your target contact rate, minus the revenue from recalls today. This is the realistic figure, and the one to plan around.
Why Recall Lists Go Uncontacted
The problem is rarely that a practice does not know who is overdue. It is that contacting them is repetitive work that loses to whatever is urgent at the front desk.
The list is built but never worked
Most practice management systems can produce an overdue recall report in seconds. Working it means calling or messaging each patient, handling the replies, and rebooking. When reception is busy, that work is the first thing dropped, and the list grows quietly in the background.
- Run the overdue report monthly and record the count so you can see the trend
- Give the list an owner, or it belongs to nobody
- Separate the list by recall type so clinically urgent recalls go first
- Track contact rate as a number, not as a feeling that it is being done
One message is not a contact
A single SMS that goes unanswered is not a contact attempt, it is a notification. Contact means the patient responded, or a person spoke to them. Practices that count sent messages as contacts overstate their contact rate and cannot understand why attendance does not follow.
- Count a contact only when the patient replies or is spoken to
- Follow non-responders with a second channel, usually a call
- Make booking possible inside the reply, not through a separate step
- Record the outcome per patient so the same person is not chased twice
Stale contact details hide the problem
A recall message sent to a number that changed two years ago looks like a contact attempt in the system and is nothing in reality. Before scaling any recall process, check how many overdue patients have a mobile number that has been confirmed at a recent visit.
- Confirm mobile numbers at every check-in, not only at first registration
- Flag bounced messages and failed calls as unreachable, then update the record
- Deduplicate patient records before running a campaign
- Check consent and communication preferences are recorded and respected
Capacity decides how much you can recover
A better contact rate only produces revenue if there are appointments to book into. Check the extra patients figure from the calculator against your free appointment capacity over the next two to three months, and pace the campaign so recalled patients are seen within a reasonable time of being contacted.
- Contact the list in batches sized to your available appointments
- Prioritise recalls with the greatest clinical need
- Hold some short-notice capacity for the patients who respond quickly
- Re-run the calculator quarterly with the new overdue count

Where do I find the number of overdue recall patients?
Most practice management systems have a recall or reminder report that lists patients whose recall date has passed without a booked appointment. In dental software it is often called an overdue or lapsed patient report. Run it for the recall types you actually act on, and use the count it gives you. If the report includes patients who have left the practice or are deceased, clean it first, because those inflate the list and depress your apparent contact rate.
How do I work out my current contact rate?
Take a recent month. Count the overdue patients who were on the list at the start of the month, then count how many of them were reached, meaning they replied to a message or spoke to a staff member. Divide the second by the first. Sent messages with no reply do not count as contacts. Most practices find the honest figure is lower than they assumed, which is exactly why the calculator asks for it.
What attendance rate should I use?
The share of contacted overdue patients who go on to book and attend. If you track outcomes per patient, use your own figure. If you do not, count bookings made from recall contacts in a recent month and divide by the number of patients contacted, then reduce it for the no-shows you saw. The rate varies a great deal by recall type, so if you run the calculator for one recall category at a time you will get a more useful answer.
Should I enter the consult fee or the value of treatment that follows?
It depends on what you want the result to show. For a check-up recall, the consult fee is the honest figure. For recalls that typically lead to a treatment course, entering the average value of that course gives a truer picture, and the visits per patient slider lets you account for a course spread across several appointments. Use one approach consistently. Mixing the two overstates the result.
Is a 100 per cent contact rate realistic?
No, and the calculator does not use it as a target. The unrealised revenue figure uses 100 per cent only to show the ceiling of what the list holds. The recovered figure uses your target contact rate, which should be set at something your process can reach. Some patients will have moved, changed numbers or chosen another practice, and no amount of contact effort reaches them.
Does this tool store anything I enter?
No. The calculation runs in your browser and nothing is sent to us. Your slider positions are kept in your own browser storage so they are still there when you come back, and the reset button clears them. Only aggregate figures are asked for. Do not enter patient names or any patient-level information into this or any similar web tool.
