““Around my neck of the woods plumbers charge from $65 to $85 an hour.
Counting a normal working day (8 hours), normal work year (2080 hours a year), and an average plumber wage, even though it’s the plumbing company that’s charging, that’s $156,000 a year.
Most plumbers I know work more than 8 hours a day so it would probably be more than that.”
You say that you know a large number of plumbers (you use the words “most plumbers I know”)well enough to know how many hours they book annually.
How many plumbers do you really know well enough to know how many hours that they work per year?
To give you a specific number - 2.
Now dispute my numbers as posted or stop nitpicking
Do you disagree that an average hourly rate in my area for plumbing work is $75 an hour?
Do you dispute that a normal work week is 40 hours?
Do you dispute that a normal work year, in hours, is 2080?
Do the math.
I answered a question to the best of my ability.
Once again, what have you done other than nitpick my answer with vague possibles?
