A phone report can show that a call was not answered. It cannot show that the caller would definitely have become a patient. That is why a useful missed-call estimate needs more than a large treatment-plan value multiplied by every unanswered ring.
For a chiropractic owner in the US or Canada, the goal is a defensible working estimate. It should help you decide whether reception needs attention without turning uncertain demand into promised revenue. Start with a defined period, your own records and assumptions that another person can inspect.
Which missed calls could actually become new patients?
Separate prospective new-patient inquiries from existing-patient calls, repeat attempts, spam, suppliers and wrong numbers. Ten unanswered calls are not necessarily ten different people seeking care.
Use the information your phone and booking records legitimately provide. If staff later returns a voicemail and the person books, that inquiry was recovered. If the reason for a missed call is unknown, label it unknown rather than classifying it as a new patient.
Our missed-call measurement guide explains how to combine phone reports, test calls and callback records. That gives you a better starting point than choosing an industry average.
What is a reasonable formula?
Use this planning formula:
Expected unrecovered revenue = unique missed new-patient inquiries × booking probability × attendance probability × collected revenue per attended new patient × unrecovered share
Choose one measurement window for each input. Booking probability means the share of comparable inquiries that becomes an appointment. Attendance probability means the share of those appointments that actually attends.
The unrecovered share accounts for callers who do not later book through a callback, online booking or another route. Keep these stages separate. If your booking figure already counts attended patients, do not multiply by attendance again.
This estimates revenue associated with opportunities, not profit and not proof that the phone caused every loss.
What does the math look like in a worked example?
Here is a hypothetical example, not a benchmark, client result or service price. Assume a US clinic identifies 10 unique missed new-patient inquiries in one month.
For planning only, suppose:
- Half would have booked if reached: 10 × 0.50 = 5 bookings.
- Four out of five bookings would attend: 5 × 0.80 = 4 attended new patients.
- Average collected revenue over the first 90 days is USD $400 per attended new patient.
- Half of those opportunities are recovered later: the unrecovered share is 0.50.
Then 10 × 0.50 × 0.80 × USD $400 × 0.50 = USD $800 in estimated unrecovered 90-day revenue associated with that month’s inquiries.
The estimate per missed inquiry is USD $800 ÷ 10 = USD $80 under those assumptions. It is not a claim that every missed call costs $80 or that AI reception would recover the entire $800.
Why not use the full value of a treatment plan?
A quoted plan is not collected revenue. Patients have different needs, coverage, attendance and payment patterns. Some never book, and some attend one visit.
Use actual collections for a defined group of new patients and a defined time horizon. For example, compare first-visit collections separately from collections over 90 days. Do not add those two figures together when one already includes the other.
Clinical recommendations must remain based on patient need. A revenue estimate is not a reason to assume everyone should receive the same number of visits. Keep financial planning separate from clinical decisions and treatment recommendations.
How should Canadian clinics use the example?
Use the same structure with your own numbers in CAD. Do not copy a USD value into a Canadian forecast or mix private-pay collections with billed amounts that have not been paid.
For example, if your hypothetical inputs remain 10 inquiries, 0.50 booking probability, 0.80 attendance and 0.50 unrecovered share, but your own planning value is CAD $250, the calculation is 10 × 0.50 × 0.80 × CAD $250 × 0.50 = CAD $500.
That is another worked example, not an assertion about Canadian clinic performance. Where insurer-funded workflows affect payment timing, use the collections period your accountant considers appropriate and show it beside the number.
How do callbacks and online booking change the estimate?
They can reduce the amount you should call unrecovered. Match missed inquiries against later bookings where your records allow it, using your practice’s access and privacy rules.
Avoid counting one person as lost because they first called unsuccessfully but booked online the next day. Also avoid crediting a callback twice when the same inquiry appears in a phone report and a front-desk spreadsheet.
Set a review window and keep using it. A comparison becomes misleading if one month allows a week for recovery and another allows a month. Record cases you cannot match instead of quietly treating them as losses.
Is recovering missed-call revenue the same as making profit?
No. Revenue and contribution are different. Additional appointments may involve clinician time, supplies, payment fees and other costs. Your clinic may also have limited capacity.
If there is no suitable new-patient availability, answering more calls may lead to requests rather than additional attended visits. That is still useful information, but it changes the business case.
Test a conservative scenario alongside your main estimate. In the US example, changing booking probability from 0.50 to 0.30 gives 10 × 0.30 × 0.80 × USD $400 × 0.50 = USD $480. The difference shows how much the answer depends on assumptions rather than a universal call value.
What should an owner measure before changing reception?
Gather unique inquiries, answer outcomes, callback attempts, confirmed bookings and attendance. Break out opening time, lunch, busy periods and after hours so you can see where coverage fails.
Keep the information needed for analysis within approved practice systems. For US patient-data workflows, we sign BAAs and use vendors that offer BAAs. Canadian practices should review applicable privacy and messaging-consent requirements with their advisor.
Start by improving the missed-call and after-hours process, not by buying unrelated workflows. Our AI reception for chiropractic clinics focuses on that first.
