Calculate the Sample Standard Deviation. 1  Calculate the mean or average of each data set. 2  To do this, add up all the numbers in a data set and divide by the total number of pieces of data. 3  For example, if you have found numbers in a data set, divide the sum by 4.
Over the average mileage of a commercial truck, usually around 130,000 miles, this equates to about $1.38 per mile, but the costs that make up this figure are varied. The most fundamental cost for any trucking company is the cost of the truck, trailer and the driver. Trucks arenât cheap.
But for general freight I had to have $1.25 per mile. For oilfield it was minimum of $2.25 for just the truck and $2.50 and up for the trailer. If it was a short run (under 100 miles) then I charged a day rate of $450 for the truck/trailer combo.f it was me Iâd ask him point blank what heâs charging per mile, since if heâs only charging $1.75 and paying 70%, that would be $1.23 per mile to the truck. Thatâs not real good pay IMO; if heâs charging $3.00 then it works out to be $2.10 per mile at 70%, which is very decent pay for non oilfield freight.
