The expenses I named,are, what every o/o will incur, and that is not even everything. The untimely, unforeseen ones are the ones that get you. Did it 10 years until 1985. Was pretty good until deregulation, and many freight rates, especially truckload will decline anytime the economy slows down. Good luck...
I did it for 9 years....from '84 to '93.......Got out of it when fuel went over $1.10 a gallon. My "break even" point was $.85 a mile....After that,...all money was profit......
Last two years,.....I only hit a couple days a month when my profits exceeded $.85 a mile......
It seemed that large truckload carriers were undercutting many smaller O/Os for loads out of..."undesirable" areas......I had a good deal with loads into Manhattan and surrounding NYC out of the Midwest......and marginal-paying backhauls out of Jersey that covered my costs.....
JB, Schneider, and other large box carriers started offering shippers discounts as low as $.75 a mile just to get their drivers out of the NY Metro area for the weekend. Upshot was that all the shippers started holding their loads from Wednesday on.....to get the "discount".....
One other thing........Run it like a business.......Too many guys think that being an O/O means Big Hammer, Large Chrome Pipes, Roaring Jake Brake, Shiny Wheels..........
....and then they cut rates so bad, they can't afford skirting for the broke-down mobile home they (sometimes..) live in.......
Have no clue what they're making per (hub) mile........But, Man! Listen to those Straight Pipes!
Don't be like that.........95% of truck drivers are hard-working bill-payers,.....and 5% are still little boys playing trucks in the sandbox........cutting rates just to roll the wheels......
