Lets say this is your very first load.
My 1st question is how far is it to the pick up,then miles load is going,and what express center will I be in.The last is very important,as if you have a long dead head to pick up,no matter how good the load pays,if your going to a dead express center,that can eat up you profit for the week.
When you ask what the pay is for all miles,they only give you mile to pick up and delivery,you need to know where your going to layover.If the load your doing goes to Montana,does it really pay enough to dead head to a dead ex center like Omaha or Denver
Next is pieces and weight,do You really have enough space to put the load in.You might have personal items that might take up cargo space
Yes, there always the hassel factor.Give me a load that is going to be a hassel,I want paid for it,and knowing I'm going to be in an area that I'll be layed over for a while,goes into this,along with Haz loads border crossings,slow deliver spots.
Now my bottom line,this works for me,at least it has for over 20 years.
I take the miles from layover to pick up,miles to delivery,and where do i want to layover after load is complete,not always
where the company would have planned
total these miles,and divide by the lowest miles per gallon your truck might get if in adverse conditions.
Now multiply this by the average dollars that fuel is going for,if there is a hassel factor,I add $100 to the figure.
Now divide this figure by the amount of advance the company will give you,if the advance will take care of business,without going into your own plastic,I'll do the load.Remember,In these figures I've already put in to the equation miles to layover,so even if I'm 1000 miles from layover,I've already planned for that.
Hope this helps,all the previous advise is good,this is just the way I do it
