How reliable is baking fuel into your cost per-mile?
I have been wondering this for a while.
We all know how important it is to know your CPM (fixed + variable). We also all know fuel is generally the biggest variable cost. And most of the advice out there says take your average fuel spend per week or month and fold it into your CPM. I get why. It simplifies the number.
But that average was built on last week’s (or months) diesel price, last week’s loads, last week’s weather. Any new loads you may run in the future may be heavier, the forecast ma shows headwinds, and diesel prices jumped or decreased. The CPM says you’re fine but are you really?
Does this make sense or am I over complicating things?
