Missed-call calculator
What are missed calls costing you?
Four inputs, plain arithmetic, and a number you can check against your own books.
To estimate what unanswered calls cost your practice, multiply your missed calls per day by the share of callers who never try again, then by your average revenue per visit, then by your working days per month. The calculator below does that arithmetic and compares the result against published Clinivocx pricing.

Tell us about your practice
Count MDs, NPs, and PAs who have their own schedule. Don't count front-desk or medical assistants.
If you have never measured it, count voicemails and unreturned numbers for one week and divide by five.
Use your own average collected revenue per visit, not your billed charge.
Leave at zero if you don't use one.
These are your numbers, not ours. Every figure below is arithmetic on what you typed, and nothing else.
Results
Live estimates based on your inputs.
Estimates only. Real numbers vary by practice, payer mix, and how many callers try you again the next morning.
The formula
The arithmetic, written out
No proprietary model. Four numbers you can source from your own phone system.
monthly loss = missed calls/day × share who never call back × average visit revenue × working days
A worked example. A two-physician family practice pulls its call records and finds 10 calls a day ring out or hit voicemail. Checking the following week, roughly a third of those numbers never appear again. Their average collected revenue per visit is $200, and they work 21 days a month.
10 × 0.33 × $200 × 21 = $13,860 per month
That is about $166,000 a year, and it is a conservative floor: it counts one visit per lost caller and ignores everything that patient would have been worth afterwards. Halve the never-call-back share if you think a third is high. The result is still a five-figure annual number for most small practices.
What the literature supports
Published work on outpatient no-shows documents that unused appointment slots carry a real per-clinic cost rather than being free capacity (Kheirkhah et al., BMC Health Services Research, 2016, PMC5130951). That research is about no-shows, not missed calls, so treat it as an anchor for one idea only: an empty slot has a price. A call that would have filled a slot and a no-show that empties one are the same economic event.
The long version, with the peak-hour breakdown and a reduction playbook, is in the cost of missed calls. Coverage prices are on pricing.
Beyond the numbers
Three things the calculator cannot price
The arithmetic covers revenue. These are the reasons practices actually switch.
The phone is answered at 2 AM
Nobody hears a ring tone or a voicemail greeting, whatever hour they call.
Callers get an answer, not a queue
The first thing a new patient learns about you is that someone picked up.
Your front desk stops interrupting
Routine bookings and refill messages stop pulling staff away from the person in front of them.
