You suspect you're losing money to the phone, but you can't prove it. The call log shows a number you never open. The front desk swears they catch everything, yet you watched three lines ring out during Monday's rush while two staff were checking patients out. Somewhere in that gap is a new patient who found another practice on the same search page — and you have no idea if that happened once last week or thirty times last month. Without a number, "we should answer more calls" stays a hunch you can't budget against.
A dental AI receptionist ROI calculator turns that hunch into a dollar figure. It takes your real inputs — call volume, the share you miss, what a new patient is worth — and shows what those lost calls cost you every month, then weighs it against the price of fixing the problem. DentalReception AI answers every call in under two rings and books the appointment live, 24/7, writing it straight into Dentrix, Open Dental, Eaglesoft, Curve Dental, or CareStack. The calculator exists to show you whether that's worth from $49/mo. For most practices, the lost calls dwarf the subscription.
The concept: what an ROI calculator actually measures
ROI here is simple. You're comparing one number — the revenue you currently lose to unanswered calls — against another — the cost of an AI receptionist that answers them. The first number is almost always larger, and the gap is your return.
The inputs are things you already roughly know:
- Monthly inbound calls — pull this from your phone system or PMS call report.
- Share of calls missed — the industry average is 25–35% (about 1 in 3) of dental calls going unanswered, at lunch, after hours, and during spikes. Use your own number if you have it; the average if you don't.
- Share of missed calls that are new patients — not every missed call is a new patient, but the ones who hang up and dial the next result usually are.
- New-patient value — the industry average is $600–$1,200 in year one. Pick a figure that matches your case mix.
Multiply those together and you have the monthly revenue walking out the door. Subtract the cost of answering it, and you have your return.
A worked example
Take a single-location practice that handles 1,000 inbound calls a month.
| Input | Value used | Source |
|---|---|---|
| Monthly inbound calls | 1,000 | Practice phone report |
| Calls missed | 30% (industry average) | 300 missed |
| Missed calls that are new patients | 1 in 5 | 60 new-patient calls lost |
| New-patient value (year one) | $600 (conservative end) | Industry average |
| Monthly lost revenue | $36,000 potential | 60 × $600 |
Even if the AI recovers only a fraction of those 60 calls, the math is lopsided. Book just three of them and you've covered the from $49/mo subscription several times over. Everything past that is margin. And this example uses the conservative $600 new-patient figure and ignores reschedules, hygiene recall, and after-hours calls entirely — all of which the same system handles on the same flat fee.
The point of the exercise isn't the exact dollar. It's the order of magnitude: the cost of missing calls runs in the tens of thousands; the cost of answering them runs in the hundreds.
Why the numbers favor answering
A part-time front-desk hire to chase coverage costs $2,500–$3,500/mo loaded (industry average) and still goes to lunch, still sleeps, and still can't hold two calls at once. An answering service at $1.00–$1.50/min takes a message but can't write into your schedule — so the patient waits for a callback that often never converts. DentalReception AI answers unlimited simultaneous calls and books them live for one flat fee, which is why the ROI line tilts the way it does.

Plug your own numbers in
The calculator is most useful when you stop using averages and use your data. Pull your actual monthly call count, your real miss rate if your phone system reports it, and the new-patient value your accountant would recognize. The output is a monthly figure your office manager can act on — and a break-even that, for nearly every practice, lands in the single digits of recovered calls.
Frequently asked questions
What numbers do I need before using the ROI calculator?
Three things, all of which you can estimate in a few minutes. First, your monthly inbound call volume — most phone systems and practice management systems report this. Second, the share of calls you miss; if you don't track it, use the industry average of 25–35%. Third, the value of a new patient in year one, with the industry average landing around $600–$1,200 depending on your case mix. With those three inputs the calculator estimates your monthly lost revenue and compares it to the cost of answering. You can refine any input as you get better data — the more accurate your inputs, the more accurate the return.
Is the new-patient value figure realistic for my practice?
The $600–$1,200 range is an industry average for first-year value, and your real number depends on your services and payer mix. A practice that does mostly hygiene and basic restorative sits toward the lower end; one with implants, ortho, or heavy treatment plans sits higher. The calculator lets you set your own figure, so you're not locked into the average. We recommend starting conservative — the example here uses $600 — because the math favors answering calls even at the low end, and a conservative input makes the result harder to argue with.
Does the calculator account for the subscription cost?
Yes. The return is the lost revenue you recover minus what you pay to recover it. DentalReception AI runs on a flat monthly subscription, so the cost side is a fixed, predictable line — not a per-minute meter that climbs with volume. The calculator subtracts that fixed cost from the recovered revenue to show net return, and because the subscription doesn't rise with call volume, busy practices see the most favorable ratio. See the pricing page for the current rate.
What if I don't recover every missed call?
You won't need to. The worked example shows the break-even sits at roughly three booked new patients a month — a small fraction of the calls a typical practice misses. The calculator is deliberately built so that even partial recovery clears the cost. In practice DentalReception AI answers every call instantly, including the simultaneous and after-hours calls a front desk physically can't reach, and follows up automatically on the rare call that still drops — so recovery tends to be high. But the ROI case doesn't depend on perfection; it holds at conservative recovery rates.
