How many calls does a dental practice typically miss?

Industry estimates put missed-call rates for dental practices at roughly 25-35% of inbound calls, driven by busy front desks, lunch breaks, after-hours enquiries and overlapping calls. Most callers who reach voicemail book with the next practice that answers.

How does this calculator estimate lost revenue?

It multiplies your missed calls per month by the share of answered calls that normally book an appointment, then by your average new-patient value. That gives the new-patient revenue lost to unanswered calls each month and year.

How much can an AI receptionist recover?

A 24/7 AI receptionist answers every call and captures bookings that would otherwise go to voicemail. The calculator applies a recovery rate (default 85%) because not every missed call is a new patient - some are existing patients, wrong numbers, or callers who ring back later.

Is this calculator free and private?

Yes. It is completely free and runs entirely in your browser. None of the values you enter are sent to a server.

The AI pays for itself with just 0,25 recovered new patient(s) per month.

Assumptions: Missed bookings are valued at the same conversion rate as answered calls. The AI recovers 85% of missed bookings (not 100% - some callers are existing patients, wrong numbers, or call back later). Front-desk cost is shown for context and is not subtracted, since an AI receptionist augments your team rather than replacing it.

How the Maths Works

No hidden numbers. Here is exactly how each figure above is calculated from your inputs:

1. Missed Calls

Missed Calls/Month = Calls/Day × (Missed % ÷ 100) × Working Days/Month

2. Lost New-Patient Revenue

Lost Revenue/Month = Missed Calls/Month × (Conversion % ÷ 100) × New-Patient Value

3. Revenue Recovered by the AI

Recovered/Month = Lost Revenue/Month × (AI Recovery % ÷ 100)

4. Net Gain after AI Cost

Net Gain/Year = (Recovered/Month × 12) − (AI Monthly Cost × 12)

5. Return on AI Spend

ROI % = (Net Gain/Year ÷ Annual AI Cost) × 100

6. Break-Even

Break-Even Patients/Month = AI Monthly Cost ÷ New-Patient Value

Why dental practices lose so many calls

Front desks are busy with patients in the chair, lunch breaks, after-hours enquiries, and overlapping calls. Industry studies put missed-call rates for dental practices around 25-35%, and most callers who reach voicemail simply book with the next practice that picks up. A 24/7 AI receptionist answers every call, captures the booking, and hands warm patients to your team - turning lost revenue back into appointments.
