Frequently asked questions
How much does a missed call actually cost a contractor?
It comes down to three of your own numbers: how many calls you miss, the share that would have booked, and your average job value. Multiply them and you see the revenue walking out the door each month. The calculator does the math for you.
How do I estimate how many calls I miss?
Check your phone log or call-tracking for unanswered and after-hours calls over a typical week, then scale it to a month. If you are not tracking calls yet, start there — you cannot recover what you cannot see.
What can I do about missed calls?
The common fixes are a fast call-back routine, an after-hours answering service, or an AI receptionist that books or captures the caller. Weigh the recovered revenue above against what a solution costs before you commit.
Does answering more calls really pay off?
Only if the recovered work clears its cost. Use the payback step to compare the revenue you would recover against a tool or service’s monthly price — if it does not clear, it is not worth it.
What do missed calls cost your shop?
Your numbers, your math — computed in your browser, nothing is sent anywhere.
Estimated booked revenue lost to missed calls:
This is an estimate built ONLY from the numbers you entered above — change them and it changes. It is not a prediction, a guarantee, or an ROI claim about any product.
If that number hurts, the fix is usually answering, not advertising. Start with the honest breakdown: how AI receptionists actually work and what they cost (written for plumbers, the math fits any phone-booked trade). Our top pick in that category is LeadTruffle (affiliate link) — or run your whole shop through the free Tool Finder.

Step 2: Would an AI receptionist pay for itself?
An AI receptionist answers and books the calls you are missing for a flat monthly fee — roughly $200–$700/month at current market pricing. Verified vendor numbers are in our AI receptionist cost guide. Enter what you would expect to pay:
