Three questions, your own numbers, and a figure you can check on paper. Nothing is stored and there is no form in the way.
Outside hours, at lunch, on a roof. If you do not know, this is the number worth counting for one week — the rest of this page is guesswork without it.
The whole job, not the call-out fee. Use what you would invoice, before parts if that is how you think about it.
Your guess, and it is the number the whole answer swings on. Nobody knows this one, which is why the result below is a range rather than a figure.
Your arithmetic
$49,050a year
somewhere between $24,570 and $73,710
This is your three numbers multiplied together. It is not a benchmark, it is not from anybody else's data, and the only one of the three I can help you check is the first.
Most owners do not know how many calls they miss, because a missed call leaves no record worth the name. Voicemail catches the ones who bother to leave a message, and the ones who do not are invisible — they ring the next name on the list and you never learn it happened.
If you want the real figure, your phone provider's call log has it. Pull one week, count the calls outside your hours that went unanswered, and put that number in above. It takes about ten minutes and it is the only part of this page I cannot do for you.
