ROI calculator
What do missed calls cost your practice?
Enter your numbers. Most practices recover the subscription in the first week. The formula is deliberately simple: missed calls per day, the share of those callers who wanted to book, and what a visit is worth to you, over 22 working days.
Missed calls × share that books × visit value × 22 working days. No waitlist fills or no-shows avoided are included; those come on top.
Recovered per month
Per year:
Practice plan ($349) pays back in working day(s)
Group plan ($699) pays back in working day(s)
How to find your three numbers
Missed calls per day
Your phone system's call report shows unanswered and abandoned calls. If you do not have one, count the voicemails and hang-ups for three days and average them. Include after-hours calls: a practice that is open 9 to 5 misses every call between 5 PM and 9 AM, and those are often the ones that book.
Share that would book
Listen to a week of voicemails. Callers asking for an appointment, a reschedule or whether you take their insurance count as booking intent. Most practices land between 30 and 50 percent. Pharmacies, reps and wrong numbers do not count, and Clinic Answering Service does not bill for them either.
Average visit value
Use collections per visit from your practice management report, not charges. Dental hygiene typically collects $150 to $250; a primary care visit $120 to $200; a PT session $90 to $150; a therapy session $120 to $220. New patients are worth more over a year, so this is conservative.
What the calculator leaves out
The number above only counts missed calls that would have booked. Three more sources of revenue show up once Clinic Answering Service is live, and the weekly revenue ledger reports each one separately:
- Cancellations filled. When a patient cancels, Clinic Answering Service calls and texts the waitlist until the slot is taken. A dental office filling two hygiene slots a week recovers roughly $1,500 a month on its own.
- No-shows avoided. Patients whose coverage was confirmed on the call, and who received a confirmation text and a reminder, show up more reliably than patients who left a voicemail.
- Staff time. Every call Clinic Answering Service handles end to end is a call the front desk did not take, and every intake collected by SMS is a form nobody typed in. Estimate it yourself: minutes of calls handled end to end each day, divided by 60, is front-desk hours returned.
Worked example: a hypothetical two-hygienist dental office
Two hygienists, one dentist, open five days. The phone report showed 12 missed calls a day, mostly during 8 to 10 AM and after 5 PM. Reviewing a week of voicemails, 40 percent were booking requests. Collections per hygiene visit were $180.
12 × 40% × $180 × 22 = $19,008 a month. On the Practice plan at $349, the subscription paid for itself by the second working day. A practice like this would typically start with after-hours forwarding, then add daytime overflow once bookings look right.
Hypothetical example with sample data, not a real customer. Your results depend on your call volume and fee schedule.
Calculator questions
Where does the "22 working days" come from?
A typical US practice is open about 22 weekdays a month. If you are open Saturdays, add them: 26 days increases the monthly figure by roughly 18%. The calculator uses 22 so the estimate stays conservative.
What is a realistic share of missed calls that would have booked?
Industry studies put the missed-call rate for medical and dental offices at roughly a third of inbound calls, and 30 to 50 percent of those callers wanted to book. We default to 40 percent; lower it to 25 if most of your calls are billing questions.
What should I enter as average visit value?
Use the collected amount per visit from your practice management report, not the charged fee. Typical ranges: $150 to $250 for hygiene, $120 to $200 for a primary care visit, $90 to $150 for a PT session, $120 to $220 for a therapy session.
Does the calculator include waitlist fills and no-shows saved?
No. It counts only missed calls that would have booked. Cancellations filled from the waitlist and no-shows avoided because coverage was confirmed are extra, and the revenue ledger in Clinic Answering Service reports them separately once you are live.
