How that number is worked out
10 missed calls/week × 30% who would have booked × $450 per job × 52 weeks = $70,200
No hidden multipliers and no assumptions of our own beyond the three numbers you entered. If the result looks wrong, one of those three inputs is wrong — usually the booking rate, which is the one most people guess at.
Why a missed call costs a full job rather than a fraction of one
A missed call is not a missed message. Most people do not leave voicemails for businesses any more — they hang up and call the next result. Your missed call is not sitting in a queue waiting for you; it is already being answered by a competitor.
That is what makes the arithmetic above harsher than it first looks. You paid for that call — through ads, through SEO, through years of building a name. All of that cost is sunk the moment the phone rings. Missing it wastes the entire acquisition cost, not a share of it.
It is also concentrated. Most contractors find the bulk of their missed calls sit in a few predictable windows: the middle of a working day when everyone is on a job, and evenings and weekends when the calls are often most urgent and most valuable.
How to get a booking rate you can trust
The booking rate is the input that decides everything, and it is the one people guess at. Three ways to replace the guess, in ascending order of effort and accuracy:
- 1
Ask whoever answers the phone
Your office manager has a rough sense of what proportion of inbound calls become work. It is not precise, but it beats a number from an article.
- 2
Count for two weeks
Tally answered calls and how many became booked jobs. Two weeks is enough to see a pattern without waiting a month to act on it.
- 3
Set up missed call text back and read the replies
Once missed callers get an automatic reply, you stop estimating and start seeing. The people who reply are, almost by definition, the people who wanted to hire you — and the sales calls and wrong numbers filter themselves out for free.
What to do about the number
The instinct is to hire someone to answer the phone. That works and it is expensive, and it still does not cover evenings, weekends, or three calls arriving at once.
The cheaper fix is to respond automatically inside the window that decides the job — which is a few minutes, not an hour. Missed call text back sends the caller a text within about a minute, before they dial the next company. For higher call volumes, an AI voice agent answers, qualifies the job and books it during the call.
One ordering note that costs contractors more than anything else on this page: if you are running Google Ads and missing the calls they generate, fix the calls before increasing the budget. Paying for a click and then not answering the phone is the most expensive mistake available.
Frequently Asked Questions
There is no reliable industry figure, and any specific percentage you see quoted is usually marketing material rather than research. That is why this calculator asks for your own number instead of supplying one. Most phone systems report missed calls; if yours does not, count for two weeks and halve it.
Your own. The 30% the calculator starts with is an arbitrary placeholder, not a benchmark. Whoever answers your phone usually has a rough sense of what share of inbound calls become work, and that estimate beats any published figure.
Yes, through the booking rate. Sales calls, wrong numbers and suppliers are part of why that percentage is well below 100. If a third of your inbound calls are not customers, your booking rate reflects that and the result comes down accordingly.
To keep the arithmetic checkable. Seasonal trades miss more calls during peaks, so an annual figure built from a typical week is conservative for them. If your business is heavily seasonal, run it twice — once with a peak week and once with a quiet one — and treat the truth as sitting between them.
Often, yes. Most people no longer leave voicemails for businesses; they hang up and call the next result. That is why the calculation treats a missed call as a whole job at risk rather than a fraction of one — the acquisition cost was already spent when the phone rang.
Responding automatically inside the few minutes that decide the job. Missed call text back sends the caller a text within about a minute, before they dial the next company. It shifts the problem from needing someone available the second the phone rings to working through replies within the hour.
