Fuel Surcharge Logistics Insights
- At $3.85/gal diesel, LTL fuel surcharge adds 22.84% to your base freight charge ($+194.14 on a $850 shipment).
- For full truckload (FTL), fuel surcharge is $0.43/mile, totaling $+277.55 across 650 highway miles.
How Do Carriers Calculate Freight Fuel Surcharges?
Fuel surcharges protect motor carriers from volatile diesel swings without requiring continuous adjustments to base tariff rates. The two primary methods used in North America are:
1. LTL Percentage Matrix Model
LTL carriers publish weekly fuel tables based on the official Monday U.S. EIA Gasoline and Diesel Fuel Update. The surcharge is billed as a percentage (typically 18% to 28% in 2024–2026) applied directly to the discounted linehaul charge.
2. Truckload Cents-Per-Mile Model
FTL carriers use a standard formula: (Current Fuel Price – Base Fuel Peg) ÷ Fleet MPG. If diesel is $3.85, the base peg is $1.20, and fleet fuel economy is 6.2 MPG, the surcharge is $(3.85 – 1.20) / 6.2 = $0.427 per mile.
Frequently Asked Questions: Freight Fuel Surcharge
When do carriers update their fuel surcharges?
The US Energy Information Administration (EIA) releases the official On-Highway Diesel Fuel Price index every Monday at 4:00 PM Eastern Time. Carriers and 3PLs update their fuel schedules to take effect the following Wednesday or Monday.
Does fuel surcharge apply to accessorial fees?
Standard carrier tariffs apply fuel surcharges strictly to the base linehaul charge. However, some contract agreements also assess fuel surcharges on certain accessorial services like inside delivery or liftgate. Always inspect your contract rules circular.
Why is California fuel surcharge significantly higher?
California (PADD 5) imposes higher state excise taxes and strict California Air Resources Board (CARB) clean-fuel standards, causing California retail diesel prices to run $0.60 to $1.20 per gallon above the national average.
Can shippers negotiate fuel surcharge tables?
Yes. High-volume shippers frequently negotiate customized fuel tables with higher base pegs ($1.50 or $1.75) or capped maximum percentages to mitigate budgetary spikes.
