How do I calculate diesel fuel surcharges?

The U.S. Energy Information Administration (EIA) does not calculate, assess, or regulate diesel fuel surcharges.

  • EIA cannot tell you how to calculate a fuel surcharge. Fuel surcharges are negotiated privately by shippers and by transportation companies.
  • Each company may have its own method for calculating surcharges. Many major transportation carriers have information on their websites concerning their surcharge methodology. EIA does not endorse a particular method. You can perform an Internet search on fuel surcharges for more information.
  • EIA collects and publishes weekly retail diesel fuel price data. Many shippers, transportation companies, and truckers use that weekly retail price information in their fuel pricing formulas.
