What do your missed calls cost you?
Enter your own numbers and see what the calls and messages you miss cost you a month and a year. The sum runs in your browser: nothing you type is sent, stored or counted.
Your numbers
The formula
The calculator multiplies three numbers that you supply:
missed enquiries a week × the share that would have booked × what a booking is worth = what you lose in a week.
- A year is the weekly figure × 52.
- A month is the yearly figure ÷ 12, which is the weekly figure × 52 ÷ 12 (a little over four weeks).
- If you give the optional share that came outside opening hours, the page also shows that share of the monthly figure. It is a split of the same total, not an extra amount.
That is all it does. It does not know your trade, your town or how many enquiries could have been answered, and it does not assume anything about any of them.
A worked example
These numbers are made up to show the arithmetic. They are not a statistic and not a typical business. Replace them with yours.
| Step | Example number |
|---|---|
| Missed enquiries in a week | 10 |
| Share that would have booked | 30% |
| Worth of an average booking | 60 |
| Lost in a week | 10 × 30% × 60 = 180 |
| Lost in a year | 180 × 52 = 9,360 |
| Lost in a month | 9,360 ÷ 12 = 780 |
Getting honest inputs
The result is only as good as the three numbers. Count rather than guess: the guide what a missed call costs shows how to get each of them from your phone's call history in one week. If the figure comes out small, you have saved yourself a subscription. If it does not, you now have a number to weigh any fix against, including a person, a better voicemail or software.
What next
If the figure is worth acting on, what an AI receptionist costs sets out what drives the price, the questions to ask any vendor and Belline's plans in every market it is sold. 7 days free: 30 voice or 12 video minutes and 50 text conversations, with your website chat, the voice button on the same page, WhatsApp and Instagram all switched on, plus your phone line where Belline has a line in your country. No card: nothing is charged unless you choose a plan, and on day 8 without one Belline pauses until you do. Standard onboarding is free. Try Belle on a call or in chat before you decide.
Questions about the calculator
Where do the numbers come from?
From you. The calculator has no default figures and uses no industry average. Count your missed calls or unanswered messages for a week, estimate from your own records how many of those people would have booked, and use what an average booking is worth in your takings.
Is anything I type sent or stored?
No. The sum is done by a small script in your browser. It makes no request, sets no cookie, stores nothing and records no analytics event for what you type.
Does the result say what Belline would recover?
No. It says what the enquiries you told it about are worth on your own numbers. Whether any of them could be answered is a separate question; the trial lets you test that on your own business.
How is a month worked out?
A year is 52 weeks and a month is a twelfth of a year, so a month is the weekly figure × 52 ÷ 12, a little over four weeks.
