How can I check a hauling company’s fuel costs and idle time before buying?

Compare fuel spending with loads, distance and revenue, truck by truck. Fuel card statements, trip logs and engine data show where fuel goes and how long trucks sit running. A rise in fuel cost that outpaces the work, or a few trucks that stand out, calls for a straight explanation.

Start with fuel as a share of the whole cost picture. Ask for several years of fuel spending set against revenue and the work done. Fuel is a variable cost, and it moves with distance and load, while other costs such as insurance and payments stay put. Seeing fixed and variable costs side by side helps you understand how the business behaves when work slows.

Then look at the detail. Fuel card statements show where and when each truck filled up, and trip logs show where it went. Compare the two. Trucks that burn more than similar ones, or fill up at odd times and places, deserve a question. Ask how idle time is monitored and whether drivers are coached on it. Engine data, where it exists, can show how long each truck sat running.

Finally, ask what the seller has done about it. Have routes been changed, trucks replaced or habits shifted? Fuel prices move, so ask how pricing to customers reflects them, and whether surcharges are written into agreements. An accountant can help you see how fuel flows through the cost of goods sold and whether the margins hold when prices rise.

Key takeaways

  • Set fuel spending against revenue, distance and loads over several years.
  • Match fuel card statements with trip logs, truck by truck.
  • Ask how idle time is tracked and what has been done about it.
  • Find out how customer pricing responds when fuel costs move.
