Diesel Prices and Trucking Costs: What Shippers Need to Know
Fuel represents 20-30% of a trucking company's operating costs. When diesel prices fluctuate, the impact ripples through the entire freight market, affecting rates, surcharges, and shipper budgets.
How Fuel Affects Trucking Rates
There are two primary ways diesel impacts what you pay:
- Base rate adjustments — Carriers factor fuel costs into their pricing
- Fuel surcharges (FSC) — Variable fees that adjust with diesel prices
📊 Current Diesel Prices
National average: $3.85/gallon. West Coast (PADD 5): $4.57/gallon. Gulf Coast (PADD 3): $3.62/gallon. Track regional prices via FreightPulse API.
Understanding Fuel Surcharges
Most carriers calculate FSC using a formula tied to the DOE weekly diesel report:
- A base diesel price (often $1.20-1.50/gallon) is established
- For each cent above base, a surcharge percentage applies
- Typical: 1% surcharge per $0.05 increase in diesel
For example, if diesel is $3.85 and the base is $1.25, the FSC might be around 30% of the base rate.
Regional Price Variations
Diesel prices vary significantly by region:
- West Coast — Highest prices due to state taxes and regulations
- Gulf Coast — Lowest prices, close to refineries
- East Coast — Moderate, dependent on pipeline supply
Smart shippers consider regional fuel costs when choosing pickup/delivery locations.
Tips for Managing Fuel Costs
- Lock in contract rates during low-price periods
- Negotiate FSC caps in carrier agreements
- Optimize routing to reduce miles traveled
- Consolidate shipments to improve fuel efficiency
- Monitor weekly DOE reports for trends
