One is 160 a month, 50 a month and 70 a month. I see no money from any of those. I just bill for it and pay the taxes. I pay my dad and his friend for mowing them.
Their ZTR's and truck, my trailer. Would it be worth it for me to spend a whole day out there 2 times a month for that amount of money. Its a 45 mile drive each way.
What does it cost you to operate per hour? If you are looking at (at least) 1 and 1/2 hours to get to the jobs and get back, what would that cost you?
Now compare that to the $80 + $25 + $35 = $140 you are making to mow those three customers per visit.
Your gas costs alone could be (90 mile drive / 15 mpg) = 6 gallons * $4 gas/diesel = $24
Let's say you operate at $60 an hour. For a 90 minute commute, you're opportunity costs would be ($60 x 1.5 hours) = $90. That is the money you could be making more locally.
So take that $90 you are losing during the drive as opportunity costs, add the $24 in fuel, you are now at $114. That's $114 you are losing during that drive to bring in $140.
It's interesting to think about.
