The seven numbers a dental clinic owner should know every month

Ask most clinic owners how the practice is doing and you get a revenue figure, usually from memory, usually approximate. Revenue is a real number but it is a lagging one. It tells you what already happened and nothing about why, so it cannot tell you what to do differently next month.

Here are seven numbers that can. Each one is calculable from records you already keep, each has a rough healthy range, and each points at a specific action when it moves.

1. New patients per month

How to calculate. Count first-time patients who completed a visit. Not enquiries, not bookings. Completed visits.

Why it matters. This is the only number that measures whether the practice is growing rather than harvesting. A clinic with flat revenue and falling new patients is running down its base and will find out in about eighteen months.

What healthy looks like. It depends entirely on your size and market, so measure the trend rather than the absolute. What you want is a stable or rising twelve month rolling average. A single bad month means nothing; three in a row is a signal.

When it drops. Look at your enquiry sources before you look at your marketing spend. Most clinics discover the enquiries were arriving and nobody followed up.

2. Enquiry-to-consultation conversion

How to calculate. Consultations completed divided by enquiries received, over the same period. An enquiry is anyone who contacted you wanting treatment: a call, a WhatsApp message, a form, a walk-in asking about prices.

Why it matters. This is the cheapest number to improve in the entire practice. Enquiries are already paid for. Every point of conversion is free growth.

What healthy looks like. Well-run clinics with fast follow-up convert well above half of genuine treatment enquiries. Clinics with no follow-up system convert far less, and usually cannot measure it at all because the enquiries were never written down.

When it is low. Almost always speed. The gap between an enquiry arriving and someone responding is the single biggest driver. Same-hour responses convert dramatically better than same-day, and same-day beats next-day by a wide margin.

3. Treatment plan acceptance rate

How to calculate. Value of treatment plans accepted divided by value of treatment plans presented. Track value, not count, or a hundred scalings will drown out the case that mattered.

Why it matters. It separates a clinical problem from a communication problem. If patients accept, your diagnosis and your explanation are landing. If they do not, one of the two is not.

What healthy looks like. Varies enormously by treatment type. Track it per category rather than as one blended figure. Restorative acceptance and full-mouth-rehab acceptance are not comparable numbers and averaging them hides both.

When it is low. Three usual causes, in order of frequency: the plan was presented as a price rather than a consequence, there was no payment option offered, or nobody followed up after the patient said they would think about it. The third is the most common and the easiest to fix.

4. Recall compliance

How to calculate. Patients who attended a recall visit divided by patients who were due for one, over a rolling period.

Why it matters. Recall is the highest margin work in dentistry and the most reliably neglected. A patient who comes twice a year for a decade is worth several times a patient who comes once for a crown, and they cost nothing to acquire.

What healthy looks like. Clinics that run a real recall queue with automated reminders do substantially better than clinics relying on memory. The gap between those two states is usually the largest single revenue opportunity in a practice that already has a patient base.

When it is low. It is almost never patient reluctance. It is that nobody owns the list. Recall works when a named person works a queue on a fixed day each week.

5. Chair utilisation

How to calculate. Booked clinical hours divided by available clinical hours. Count the hours the chair could have been used, not the hours the clinic was open.

Why it matters. Your chair and your clinical time are the fixed costs. Everything else scales. An underused chair is the most expensive thing in the building.

What healthy looks like. Aim high but not maximal. A clinic running at absolute capacity has no room for emergencies, runs late constantly, and burns out staff. Deliberate slack is not waste; it is how you absorb the walk-in with facial swelling without wrecking the afternoon.

When it is low. Check no-shows and short-notice cancellations first. Empty chairs are usually a scheduling reliability problem before they are a demand problem.

6. No-show and short-notice cancellation rate

How to calculate. Appointments where the patient did not attend, plus those cancelled with too little notice to refill, divided by total scheduled appointments.

Why it matters. A no-show is lost clinical time you cannot recover, and unlike a gap in the diary you had no chance to fill it.

What healthy looks like. Clinics with automated reminders and easy rescheduling get this into low single digits. Clinics without reminders routinely run several times higher.

When it is high. Reminder timing and reschedule friction. A reminder 24 hours ahead that lets the patient reply to reschedule converts a would-be no-show into a moved appointment, which is a completely different outcome.

7. Outstanding balance and average collection time

How to calculate. Total unpaid balance across active patients, and the average days between treatment delivered and payment received.

Why it matters. Revenue you have earned but not collected is not revenue. Clinics with growing turnover and worsening cash position are almost always looking at this number without knowing it.

What healthy looks like. For clinics that collect at the point of care, this stays small. It grows in practices doing staged treatment, which is normal, but it should track plan progress rather than drift.

When it grows. Usually staged treatment without payment milestones. Tie payment stages to treatment stages and the number stops drifting on its own.

Making this a habit rather than a project

Seven numbers is too many to gather by hand every month, which is why most clinics track one. The realistic approach:

• Weekly, five minutes. New patients, no-shows, and outstanding balance. These move fast enough to act on.
• Monthly, twenty minutes. All seven, written down in the same place each time so you build a trend rather than a snapshot.
• Quarterly. Look only at the direction of the twelve-month averages. Ignore individual months; they are noise.

If pulling these numbers takes more than twenty minutes, the problem is your records rather than your discipline, and that is worth fixing first. A dashboard that surfaces these continuously, as Kythro does, mostly buys back the twenty minutes and removes the excuse not to look.

The one to start with

If you only pick one: enquiry-to-consultation conversion. It is the number most clinics cannot calculate at all, because enquiries are not recorded anywhere. Start writing every enquiry down with a source and an outcome. Within two months you will find revenue you were already paying for and quietly losing at the front desk.
