Missed-call revenue calculator.
Enter your missed calls per week, the share who would have booked, and your average job value. The calculator multiplies them by 4.33 weeks a month and shows the revenue that went to the next company. It runs in your browser and stores nothing.
Example
The boxes start with made-up Example numbers. Replace all three with your own.
Real customers only. Leave out sales calls and wrong numbers.
Measure it: call back two weeks of missed calls and count.
Revenue that went to someone else, per month
$7,794
About $93,528 over a year, from roughly 13.0 jobs a month.
Formula: 10 calls a week x 4.33 weeks x 30% x $600 = $7,794 a month (rounded to the nearest dollar).
4.33 is 52 weeks divided by 12 months.
This is an estimate from your inputs, not a forecast of what you will recover. Nothing you type leaves your browser.
How to use it
- Count missed calls. Use your phone log for the last two weeks. Count real customers only.
- Measure the booking rate. Call each one back and note how many were still open to booking.
- Average your jobs. Use the last 20 new-customer invoices for the kind of job you miss most.
The full walk-through, with a worked Example, is in what a missed call costs a trades business.
What to do about it
Start with a text sent to every missed caller (how missed-call text-back works). If the number is large, have the call answered: what an AI receptionist does for a plumber, or read about the AI Voice Wizard and the AI Voice + Review Wizard plan.
Common questions
- How does this calculator work out the number?
- It multiplies four things: missed customer calls per week, 4.33 weeks per month, the share of callers who would have booked, and your average job value. The formula is shown under the result so you can check it.
- Where do the starting numbers come from?
- They are made-up Example values, there only so the page shows a result. Replace all three with your own figures. They are not averages for any trade.
- Is my data stored or sent anywhere?
- No. The calculation runs in your browser. Nothing you type is sent, saved or shared.
- What is a realistic booking rate?
- Measure your own. Call back two weeks of missed customer calls and count how many were still open to booking. Your result depends on your trade, your area and how fast you reply.
- Does the result mean I would win all that back?
- No. It is the revenue attached to calls that went unanswered, based on your inputs. Answering or texting back would recover part of it, and how much depends on your business.
Seeing a number you do not like?
The AI Voice Wizard answers calls you cannot take, says it is an AI, captures the job and texts a booking link. It is part of the AI Voice + Review Wizard plan.
