AI receptionist ROI and payback calculator
Four inputs, one honest number. See what missed calls are leaking, what an AI voice agent recovers at a conservative one-third share, what is left after the plan price, and how many days until it has paid for itself.
Modeled, not measured: leak = calls × unanswered rate × close rate × ticket. Every input is yours to change. Presets are the same industry benchmarks used across the site; a free scan replaces them with an estimate from your own business.
How to measure ROI from a voice agent
Every AI receptionist vendor will tell you the ROI is enormous. The only number worth trusting is the one built from inputs you can check. Here is the model this page uses, in full:
- Monthly leak = inbound calls × unanswered share × close rate on an answered call × average ticket.
- Recovered revenue = monthly leak × recovery share. We default to one-third, deliberately conservative.
- Net monthly return = recovered revenue − plan price ($249 or $549). Return multiple = recovered ÷ plan.
- Payback period = plan price ÷ (recovered revenue ÷ 30), in days.
What the model does not do: it does not count website leads the agent captures (a real, separate line that the site calculator models), it does not count the after-hours calls that are disproportionately high-ticket, and it does not assume the agent lifts your close rate. Those all push the true number up. Leaving them out is the point — a number you would defend to a skeptical partner is more useful than a bigger one you would not.
Where each input comes from
- Inbound calls: your carrier or phone-system report. Most small businesses have never looked; it is usually higher than you think.
- Unanswered share: the same report, or the preset for your trade (the presets are the benchmarks used across this site).
- Close rate: what share of callers you actually book when you do answer. Be honest; the model rewards honesty.
- Average ticket: your average job, visit, or order value. Use the median if a few big jobs skew the mean.
Missed-call text-back vs. an AI receptionist
Missed-call text-back is the tool most marketing agencies sell: when a call rings out, the system sends the caller an automated text. It is better than nothing. It is also an admission that the call was missed. The homeowner with water on the kitchen floor has already dialed the next plumber by the time the text arrives; the patient in pain has already booked with the practice that picked up.
An AI receptionist answers the call. There is no missed call to text back, no voicemail step, and no second-chance dependency on the caller reading a text and deciding to reply. To compare the two in the calculator, model text-back by dragging the recovery share down — a text recovers only the subset of callers who were still shopping when it arrived — and model an AI receptionist by dragging it toward the share of callers who stay on the line when a real answer picks up.
Text-back still has a place: as the fallback if a call somehow is not answered, and as a follow-up channel after a conversation. It is not a substitute for answering.
Payback period by trade, with the default presets
Load any preset above and read the payback row. The pattern holds across trades: the plan price is less than one recovered job for HVAC, plumbing, auto repair, and med spa, and less than two for chiropractic and dental — so payback lands in days rather than months even at a one-third recovery share. The trades where it is closest are the ones with the lowest tickets and the highest answer rates, which is exactly what the model should say.
What would change the answer
- You already answer more than 90% of calls: the leak is small and the case is the website agent, not the phone.
- Your close rate is under 15%: fix the offer or the pricing before automating the front desk.
- Your calls are mostly existing customers: the agent still saves labor, but model it on staff time rather than revenue.

ROI questions, answered
How do you calculate the ROI of an AI voice agent?
Four inputs: inbound calls per month, the share that go unanswered, your close rate on an answered call, and your average ticket. Multiply them for the monthly revenue leaking to missed calls. Apply a recovery share (we default to one-third — a deliberately conservative figure), subtract the plan price, and you have net monthly return. Divide plan price by daily recovered revenue for the payback period.
What is a realistic payback period for an AI receptionist?
With the calculator's default presets and a one-third recovery share, most trades model a payback measured in days, not months, because the plan costs less than a single recovered job in HVAC, plumbing, or auto repair. Your number depends on your inputs — which is why every input on this page is editable and stated.
Why does the calculator default to recovering only a third of missed calls?
Because a conservative number you believe is worth more than an optimistic one you don't. Some missed callers were price-shopping, some already booked elsewhere, some will still hang up. One-third is the framing we use everywhere: if recovering even a third pays for the agent several times over, the decision is not close.
How is this different from a missed-call text-back calculator?
Missed-call text-back sends an automated SMS after a call rings out. It recovers some callers, but the caller still went to voicemail first, and a homeowner with water on the floor is already dialing the next number. An AI receptionist answers the call, so there is no missed call to text back. Model text-back by lowering the recovery share; model an AI receptionist by raising it toward the share of callers who actually stay on when answered.
What does the AI receptionist cost?
VoiceWeb is $249/month (website agent). VoiceWebPro is $549/month (website plus full inbound phone AI). No setup fee, no per-call or per-minute fees, cancel anytime, 60-day money-back guarantee. Those are the two plan buttons in the calculator.
Is this calculator's output a promise?
No. It is a model built from your inputs and labeled as such. To get an estimate built from your own business rather than presets, run the free scan — it reads your site and your public review count and returns a leak figure plus a working demo agent in about two minutes.
