Well lets see...to be profitable in this business, you 1st have to know what "your" cost per mile is....so to determine your profit per mile you need to know what your pay per mile is going to be, no matter which plan you are on...so if dispatch calls with a load offer of 72% of what the load pays, you still need to do a quick job of figuring out what that % figures out to per mile.pay ...
Now that being said, the pay that carrier offers will differ from one carrier to the next...and even when you are contracted under one program or the other, dispatch will quote you both ways...
Personally, I work under the % of load with my current carrier, and i prefer that because i have a "base" % and it only goes up from there..It isnt fixed and changes from load to load....but never below the base...but then there is nothing "standard" or "common" about my carrier...
