The only way to consider fuel cost or any cost for that matter is as a percentage of sales. Everyone has different customers, geography, economics, gas prices, equipment etc. so actual dollar amounts that companies spend on fuel are relevant only to them. Perfect Earth, Danmow and the others that have mentioned this before me are right on. Our fuel cost ran 5% of sales in 2013 and have historically run 3.5% to 5%. This is what you need to know for budgeting and pricing.
