Your numbers, not our marketing numbers
Everything updates as you type. Nothing gets sent anywhere — this runs entirely in your browser.
Four questions
Estimate is fine. Round numbers are fine.
—
Your weekly volume times your miss rate, across 4.33 weeks.
—
Revenue per month sitting in calls nobody answered. Not all of it is lost — some people call back.
—
Recovered revenue per month
—
Jobs per month you would otherwise never have heard about
—
How long the recovered work takes to cover this month’s bundle.
—
What one month of recovered work pays for at $199 a month.
—
Gross profit on the recovered work, not revenue. This is the number your accountant cares about.
These are estimates built on your own four numbers and two stated assumptions, not a guarantee. Your market, your reviews and how fast you answer the replies all move the number.
The two assumptions: 55% of your missed calls are real new-job prospects (the rest are suppliers, spam and the same person dialling twice), and a text-back within seconds of the call gets 30% of those back into a live conversation you would otherwise never have had. Both are deliberately conservative — explained below.
And one thing this page owes you: text-back sending switches on with our carrier A2P 10DLC registration. Until it clears, CallMitt™ logs the missed call and composes the reply for you to read rather than delivering it (one held more than an hour is never sent) — so treat every figure above as what the finished send path is worth, not as this month’s receipt.
Why we knock two big holes in our own number
Every vendor calculator you have ever used multiplies missed calls by your average job and shows you a terrifying six-figure total. That number is fiction, and you know it, so you close the tab.
Ours subtracts twice before it says anything.
Cut 1: only 55% of missed calls are prospects
Your call log is full of the lumber yard, the guy about the warranty on a job from 2023, three robocalls about your truck’s extended warranty, and Mrs. Alvarez calling twice in four minutes because she is impatient. We count her once, and we throw the rest out.
Cut 2: only 30% of the rest were truly lost
Some missed callers call back tomorrow, catch you in the truck at 5pm, or (a few) leave a voicemail. Those were never lost, so the text-back does not get credit for them. We only count the 30% who would have quietly dialled the next fencing company on Google. That 30% is our own assumption, not a measured figure: no study we can find measures what share of home-service jobs go to the first business to respond.
A made-up example: a two-person pressure-washing crew
The numbers below are a worked scenario using the same arithmetic the calculator runs. It is a made-up company, plainly labelled as one, because we would rather do arithmetic in public than invent a testimonial.
| Calls per week | 18 | An example spring week |
| Percent missed | 45% | Two people on wands, nobody in an office |
| Average job | $650 | A house wash plus a driveway |
| Close rate | 40% | Of the people they actually reach |
| Missed calls per month | 35 | 18 × 45% × 4.33 weeks |
| Of those, real prospects | 19 | Cut 1: 55% of 35 |
| Revenue riding on those calls | $5,015 | 19 prospects × 40% close × $650 (carried unrounded at 19.3) |
| Conversations the text-back recovers | 6 | Cut 2: 30% of 19 |
| Jobs recovered per month | 2.3 | 6 conversations × 40% close |
| Recovered revenue per month | $1,505 | 2.3 jobs × $650 |
| Days to pay back the $199 | 4 days | $199 ÷ $1,505 × 30.31 days |
| Months of bundle one month covers | 7.6 | $1,505 ÷ $199 |
Two and a bit extra house washes a month. That is the whole pitch. If they only recovered one job every three months they would still be ahead, which is why we price at $199 instead of $499 and why we do not ask for a card to start the trial.
Where every number in here comes from
Three published figures and one assumption of ours. Here is what each one is, where it comes from, and how much weight we put on it.
52%
of callers to home-service businesses speak with a person
From Invoca’s 2026 home-services call benchmarks (opens in a new tab) (Invoca, 2026), built on its own call-tracking data across nine home-service trades; Invoca sells call tracking. Leave out calls under 15 seconds and it is 65%, and by trade it runs from 32% to 74%. We do not use it in the math at all — it is only the suggestion next to the miss-rate field. Your own call log beats it every time, so use that.
30%
Cut 2 is our own assumption, not a measured figure
We set Cut 2 at 30%. No study we can find measures what share of home-service jobs go to the first business to respond, so we do not print one. In plain words: a caller who cannot reach you can call the next name on the list, and answering fast gives you the best chance at the job. We still assume the other 70% were never yours to lose.
Under 3%
of callers who reach voicemail leave a message
From Invoca’s call data (opens in a new tab) (Invoca, 2024). It counts messages left, not calls returned: almost nobody who reaches your voicemail leaves a message at all. If your missed calls go to voicemail, that is the system you are running today. It is not in the formula either — it is context for why the missed-call bucket is worth attacking.
$176–$9,609
national averages for one job, from a house cleaning to a roof replacement
From HomeAdvisor’s cost guides, updated June 2026: a house cleaning (opens in a new tab) $176, hiring a plumber (opens in a new tab) $341, a new fence (opens in a new tab) $3,276, a roof replacement (opens in a new tab) $9,609. The calculator ignores this and uses your own average job, because your ticket is your ticket.
What this calculator deliberately does not count
All of these are real. None of them are in the number above, because we cannot put a defensible figure on them.
Website visitors who never call
The calculator is about the phone. NapkinPrice™ works on the visitors who never call: the people who looked at your gallery at 9pm and left because there was no price anywhere. That is a separate, often larger, pile of money.
The cost of an empty seat in a truck
A crew position unfilled since April is a truck running at half capacity all season. CrewFunnel™ exists for that. We are not going to guess what your unfilled position costs, but you can.
Repeat work and referrals
A recovered customer who is happy calls you again next spring and tells their neighbour. Every recovered job here is counted exactly once, at face value.
Your evenings
Not answering the same three questions by phone at 8:40pm has a value. We have no idea how to price it, so it is worth zero in the math above and considerably more than that in real life.
Reviews you never got
You cannot get a five-star review from a homeowner who never reached you. Not counted.
Your actual gross margin
The big orange number is revenue, not profit. The margin card assumes 40%. That is our assumption, not a measured average: NAHB’s latest study (opens in a new tab) puts remodelers’ average gross margin at 29.9% for 2024 (NAHB, April 2026). If yours is 28%, do that division yourself and the answer is still comfortably above $199.
If you would rather skip the arithmetic
The whole product costs $199 a month, which is $6.54 a day. Here is the break-even in the only unit that matters, on three example jobs.
Thirty days free, no card. If the dashboard shows you zero missed calls worth chasing at the end of it, do not buy it — and tell us why, because that would be genuinely useful information.
