Home / Missed-call revenue calculator
What the calls you miss are worth
Most med spa owners know calls go unanswered. Fewer know the size of the hole. This model takes three numbers — two of which only you can supply — and shows the monthly figure. Every assumption is an input, so you can argue with it.
Your inputs
Nothing here is sent anywhere. The arithmetic runs in your browser.
Count every call that rings out, lands on voicemail, or arrives after the front desk goes home. If you do not have the figure, start at 120 and adjust once you do.
Use your own average — pull it from your practice management system rather than trusting anyone else's benchmark. Replace the default with your number.
The $164 default is the med spa average ticket reported by Zenoti, Beauty and Wellness Industry Statistics 2025. That is vendor platform data from businesses running on Zenoti, not an independent study. The same source reports a 5% med spa no-show rate.
This is an assumption, not a benchmark. Some callers ring the next med spa in the list. Others try again. Set it low to stay honest with yourself.

What this model leaves out
A calculator is only useful if you know its edges. This one is deliberately narrow, and it excludes more than it includes.
- Cost of delivery. The figure is gross revenue, not profit. Every recovered booking still consumes staff time, product and room capacity.
- Callers who never rang. People who looked at your site, saw no way to book, and left are invisible here.
- Leads that came in and then went cold. Web forms, DMs and walk-ins that nobody followed up on are a separate problem from missed calls.
- Dormant patients. The model says nothing about patients who already know you. That is a different calculation, and usually a bigger one.
- Capacity. If your injectors are already booked out for six weeks, recovering calls does not add revenue. It adds a waiting list.
- Any guarantee. This is a model driven by your assumptions. It is not a forecast, and AlphaSync is not promising you this revenue.
If the number is small once you have set honest inputs, the answer is probably not to buy software. We will say so on the call.
How the number is built
The tool takes three inputs and multiplies them in a fixed order. That is the whole model.
- Recovered bookings a month: missed calls × the share of those callers who would have booked.
- Modelled gross revenue a month: recovered bookings × your average ticket per visit.
- Modelled gross revenue a year: the monthly figure × 12.
- Return on the $3,000 monthly fee: the monthly figure ÷ $3,000.
It stops at gross revenue: staff time, product and room capacity sit outside it, so the output is not profit.
The three assumptions, all yours to change
- Calls missed a month. The slider runs 20 to 600, and every other line scales from it.
- Average ticket per visit. An open field, pre-filled with $164. Replace it with your own figure from your practice management system.
- Share of missed callers who would have booked. The slider runs 5% to 50%, and the 20% starting point is a guess, not a benchmark.
A worked example you can check by hand
Illustrative profile: the default inputs of 120 missed calls, 20% booking and a $164 visit. An example, not a real practice and not a typical one.
| Line | Arithmetic | Result |
|---|---|---|
| Missed calls a month | Your input | 120 |
| Share who would have booked | Your input | 20% |
| Recovered bookings a month | 120 × 20% | 24 bookings |
| Average ticket per visit | Your input | $164 |
| Modelled gross revenue a month | 24 × $164 | $3,936 |
| Modelled gross revenue a year | $3,936 × 12 | $47,232 |
| Return on the $3,000 monthly fee | $3,936 ÷ $3,000 | 1.3× |
The $164 default is the med spa average ticket reported by Zenoti, Beauty and Wellness Industry Statistics 2025. That is vendor platform data, not an independent study.
Reading a figure that carries your own visit value
The input most owners cannot answer from memory is what a visit is worth at their practice. AmSpa puts average spend per visit at $527. The same 24 recovered bookings produce $12,648 a month at $527, against $3,936 at $164. Same calls, different business.
American Med Spa Association (AmSpa), 2024 Medical Spa State of the Industry Report.
Both figures are anchors for a field only you can fill. Neither is your average; pull yours from your practice management system.
Where the call count comes from
Two weeks of phone records is enough: count calls that rang out, calls that reached voicemail, calls answered after hours, and calls abandoned in the queue. Leave out spam and do not count one call twice.
The model has no field for follow-up speed, a dormant patient list or repeat visits, so it says nothing about them. We publish no figure for what a patient is worth over several years, because none is credible. If the leak is an unanswered web enquiry, read speed to lead. If it is patients who already know you, start with patient reactivation.
What the figure is not
An estimate, not a promise. That number is an estimate built from your own inputs, not a promise, not a projection of AlphaSync's results, and not a claim about what any practice earns.
Where the system fits
Where the model shows a gap, the voice agent answers those calls: it picks up when the front desk cannot, asks your questions, and books into the calendar you already run. New enquiries get a reply in under 90 seconds, and the reactivation work opens the list you own. Bring your call log and your ticket to the session.
Bring your real numbers to the call
We will run this model against your actual call volume and your actual ticket, and tell you if the case is not there.
