How the calculator works
It multiplies three numbers that you supply. Nothing is assumed about your industry, and no statistics are built in. The calculator runs in your browser, and what you type is not sent or stored anywhere.
| Input | What to enter |
|---|---|
| Calls per week | All inbound calls to your business line in a typical week |
| Percent missed | The share that ring out or go to voicemail. Your phone bill or call log shows this |
| Average job value | What a typical booked job is worth to you, in CAD |
| Formula | Calls per week × percent missed × average job value × 52 = value per year |
How to read the result
Treat the figure as a ceiling, not a forecast. Not every missed call would have become a job. Some callers ring back, some were never going to book, and some were not customers at all. If you know roughly what share of answered calls turn into work, multiply the result by that share.
Then compare it with the cost of answering. Flowly AI's Starter plan is $249 CAD a month for after-hours and weekend coverage, with no setup fee.
Where an AI receptionist changes the numbers
It lowers the percent missed. An AI receptionist answers the calls you cannot, books the job into your calendar, and emails you a summary. It does not change how many people call or what a job is worth.
Your numbers
- Missed calls per week
- 8
- Value of missed calls per month
- $13,867 CAD
- Value of missed calls per year
- $166,400 CAD
Formula: calls per week × percent missed × average job value = value per week. Per year is that × 52, and per month is the yearly figure ÷ 12. This assumes every missed call would have become a job, which will not be true for every call, so treat the result as an upper limit.
Questions
Does the calculator store what I type?
No. It runs in your browser only. The numbers you enter are not sent to Flowly AI or anyone else.
Where do I find my missed-call percentage?
Your phone provider's call log or bill usually shows unanswered and voicemail calls. Count them against total inbound calls for a typical week.
Is the result what I will earn with an AI receptionist?
No. It is the value of the calls you currently miss, assuming every one became a job. Real results will be lower.
What statistics does the calculator use?
None. It uses only the three numbers you enter and the formula shown on this page.
What does it cost to have those calls answered?
Flowly AI plans start at $249 CAD a month with no setup fee. See the pricing page for all plans.
