The ROI of AI Automation: A Calculation You Can Do with Your Own Numbers
Time saved, calls no longer lost and fewer no-shows. A transparent, step-by-step model for calculating whether an AI receptionist and widget pay off — without invented statistics.
Many articles about AI promise "up to 80% savings" without showing the calculation. We don't. Instead you get a model with four items that you can work through with your own numbers in fifteen minutes. If the result is negative, AI is not a good investment for you right now — and that is a useful answer too.
Item 1: Time freed up
During an ordinary week, count how many minutes go on answering the phone, answering the same questions, finding slots and sending confirmations.
Use the real hourly cost including pension and holiday pay. Only count the time the AI can realistically take over — typically bookings and recurring questions, not advice.
Item 2: Calls and enquiries lost today
How many calls go unanswered, and how many of those do you never reach again? How many contact forms never become a customer because the reply came too late?
Be conservative with the share. Not everyone who calls would have bought.
Item 3: Fewer no-shows
Only relevant if you have appointments in a calendar. Read more in automatic reminder calls.
Item 4: The cost
Monthly subscription, any extra minutes, and setup spread over e.g. 12 months. At Aibooking.dk it is DKK 999, 2,499 or 5,999 per month depending on talk time; setup is optional. See what an AI receptionist costs.
Connect your calendar, forward your number and watch the bookings come in for 7 days — free and without a credit card.
A worked example (illustrative numbers)
A physiotherapy clinic with three therapists:
| Item | Assumption | Per month |
|---|---|---|
| Time freed | 4 hours/week × DKK 300/hour × 4.3 | DKK 5,160 |
| Lost calls | 20 calls × 25% × DKK 400 contribution | DKK 2,000 |
| No-shows | 8 no-shows × 40% rebooked × DKK 500 | DKK 1,600 |
| Cost | Professional | −DKK 2,499 |
| Net | DKK 6,261 |
The numbers are illustrative — they were not measured at a particular customer. The point is the method: replace each assumption with your own number.
What the calculation doesn't capture
- Focus: fewer interruptions mean better work, but that is hard to price.
- Customer experience: answers in seconds instead of tomorrow.
- Insight: transcripts show what customers actually ask about.
- Risk: a badly configured AI can also cost customers. So: test, read transcripts and adjust.
Measure it during the trial
The best ROI calculation is one based on real data. During the free trial you can see answered calls, bookings and call length in the dashboard, and use them instead of assumptions. See how to get started in the step-by-step guide.
