A fuel surcharge is an additional charge included in freight shipping to account for fuel costs and changes in diesel prices. It helps trucking companies cover changing fuel expenses without constantly raising their base freight rates. While businesses cannot control fuel prices, understanding how a fuel surcharge works can help them better plan transportation costs and choose the right shipping partner.
What is a Fuel Surcharge?
A fuel surcharge is an additional charge that helps carriers pay for higher fuel costs. Since diesel prices can change from week to week, shipping companies use fuel surcharges to adjust for those changes.
Instead of changing their base freight rates every time fuel prices increase or decrease, carriers keep their standard rates the same and adjust the fuel surcharge as needed.
Fuel surcharges are common in both full truckload (FTL) and less-than-truckload (LTL) shipping.
How are Fuel Surcharges Calculated?
Most carriers calculate a fuel surcharge using national diesel fuel prices. Many reference the average diesel price published by the U.S. Energy Information Administration (EIA).
Each carrier has its own fuel surcharge schedule, so the amount may vary between companies.
Several factors can affect a fuel surcharge, including:
- Current diesel fuel prices
- Distance the shipment travels
- The carrier’s pricing formula
- Changes in the fuel market
Because fuel prices change regularly, fuel surcharges may also change from week to week.
Why Fuel Prices Change
Fuel prices can rise or fall for many reasons. Changes in the global oil market, seasonal demand, weather events, and supply chain disruptions can all affect the price of diesel fuel. Because these factors are outside a carrier’s control, transportation costs can change throughout the year. Fuel surcharges help carriers respond to changing fuel markets while maintaining consistent base freight rates
Why Fuel Surcharges Matter for Businesses
A fuel surcharge can affect the total cost of shipping products. Even if freight rates stay the same, changes in fuel prices can increase transportation costs.
Understanding fuel surcharges helps businesses:
- Budget for shipping expenses
- Compare transportation options
- Plan future shipments
- Avoid unexpected freight costs
Knowing how fuel surcharges work also makes it easier to understand freight invoices and estimate shipping costs more accurately.
How LTL Carriers Help Manage Fuel Costs
Although businesses cannot control fuel prices, they can work with carriers that use efficient shipping practices to help manage transportation costs.
LTL carriers reduce waste by combining shipments from multiple customers into one truck. This helps make better use of available trailer space and reduces unnecessary trips.
Many carriers also improve efficiency by:
- Planning the most efficient delivery routes
- Reducing empty miles whenever possible
- Using technology to improve load planning
- Maintaining trucks to improve fuel efficiency
Efficient operations are only part of the equation. Working with dependable carriers also helps keep shipments on schedule and reduces unnecessary delays. That’s why many logistics providers have a carrier vetting process to evaluate safety, reliability, and performance before partnering with a carrier.
Tips for Managing Transportation Costs
Fuel prices will continue to change, but businesses can take steps to better manage shipping costs.
Consider these best practices:
- Plan shipments ahead of time whenever possible.
- Consolidate multiple orders into fewer shipments.
- Compare shipping options based on your needs.
- Work with a trusted logistics partner.
- Review freight invoices to understand fuel surcharge charges.
The logistics provider you choose can have a significant impact on both shipping efficiency and transportation costs. Understanding the differences between an asset-based carrier and a freight broker can also help you determine which option best fits your business.

Managing Fuel Costs Starts with Smarter Shipping
A fuel surcharge is an important part of freight shipping because it helps carriers respond to changing fuel prices. While businesses cannot control the cost of diesel fuel, they can make smarter shipping decisions that help reduce overall transportation expenses.
