Fuel Surcharge

What Is a Fuel Surcharge?

A fuel surcharge is an additional fee added to freight rates to account for fluctuations in fuel prices, allowing carriers to adjust for fuel cost changes without renegotiating base rates for every shipment.

How Is a Fuel Surcharge Calculated?

Carriers typically calculate fuel surcharges based on a published fuel price index (like the U.S. Department of Energy's diesel price index for trucking), applying a sliding scale where the surcharge percentage rises and falls with the reference fuel price, usually updated weekly or monthly.

Why Fuel Surcharges Matter

Fuel surcharges can represent a substantial and variable portion of total freight cost, particularly during periods of fuel price volatility. Shippers negotiating freight contracts should understand exactly which fuel index and calculation method a carrier uses, since methodologies vary and directly affect how much the surcharge fluctuates.
