Pro tip:Rates shown are approximations based on published carrier tariff schedules and are for estimation purposes only. Always verify with your carrier's current FSC table before quoting. Many shippers negotiate FSC caps of 20–25% in their carrier contracts to limit exposure when diesel spikes.

Why FSC Rates Vary by Carrier

Each carrier publishes their own fuel surcharge table. While all reference the Monday DOE price, rate increments and starting thresholds differ — meaning ODFL and FedEx can be 2–3% apart at the same diesel price.

📅

Weekly Update Cycle

The DOE publishes national average diesel prices every Monday morning. Carriers typically update their FSC tables to take effect the following Monday, giving shippers roughly a week of visibility before rates change.

📝

Negotiate FSC Caps

High-volume shippers regularly negotiate maximum fuel surcharge caps in carrier contracts — commonly 20–25%. This limits exposure when diesel spikes and makes freight budgeting more predictable.

LTL Carrier Fuel Surcharge Comparison — April 2026

Each carrier calculates their fuel surcharge differently. This table compares how major LTL carriers price their FSC at the current diesel price level. Use this to compare total freight cost — not just base rates — when selecting a carrier.

💡 Pro Tip

The spread between the lowest carrier FSC (Estes at ~24.1%) and the highest (XPO at ~26.9%) is nearly 3 percentage points. On a $1,000 base freight charge, that's a $28 difference per shipment from FSC alone. Always compare total cost (base + FSC + accessorials), not just the base rate.

📌 Key Facts — As of March 2026
  • As of March 2026, LTL fuel surcharges range from approximately 22%–28% of the base linehaul rate depending on carrier and the current DOE diesel price.
  • The U.S. Energy Information Administration (EIA) publishes weekly retail on-highway diesel prices every Monday, which carriers use to set the following week's fuel surcharge.
  • Major LTL carriers calculate fuel surcharge using a stepped formula: the surcharge increases by approximately 0.45%–0.50% for every $0.05 increase in the DOE diesel price above a trigger price.
  • A fuel surcharge cap negotiated at 20%–25% in carrier contracts can save shippers thousands of dollars when diesel prices spike.

Frequently Asked Questions

Common questions about fuel surcharges and LTL carrier rates

What is an LTL fuel surcharge?

An LTL fuel surcharge (FSC) is a percentage added to the base linehaul rate to offset carrier fuel costs. It is not a fixed cost — it fluctuates weekly based on the DOE national average on-highway diesel price. At $3.89/gallon diesel, most major LTL carriers charge between 22% and 28% FSC on top of the base freight rate.

How is the LTL fuel surcharge calculated?

Each carrier uses a proprietary stepped table that references the DOE weekly diesel price. A carrier might charge 1.5% FSC at $1.25/gallon diesel, then add 0.475% for every $0.05 increase above that trigger price. For example, at $3.89/gallon, a carrier with that formula would charge approximately 26.5% FSC. The DOE price is published Monday; the new FSC rate typically takes effect the following Monday.

Where does the DOE diesel price data come from?

This calculator uses live data from the U.S. Energy Information Administration (EIA) Weekly Retail On-Highway Diesel Prices survey (Series EIA-0002). The EIA surveys approximately 900 retail outlets weekly and publishes national and regional averages every Monday at noon ET. The national average is what most LTL carriers reference for fuel surcharge calculation.

Can I negotiate a fuel surcharge cap with my carrier?

Yes — most LTL carriers will negotiate fuel surcharge caps in annual contracts. A typical negotiated cap is 20%–25% of linehaul. This means even if diesel prices spike to $5.00+/gallon (pushing the uncapped FSC to 35%+), you pay the capped rate. For shippers with $500,000+ annual LTL spend, FSC cap negotiation is one of the highest-ROI contract negotiations available.

How much does the fuel surcharge add to my freight bill?

At a 25% FSC rate on a $500 base freight charge, the surcharge adds $125, bringing the total to $625. At 30%, the surcharge is $150 on a $500 base. For high-volume shippers spending $100,000/month on LTL base freight, each 1% increase in FSC costs $1,000/month — or $12,000/year.

Do all LTL carriers use the same fuel surcharge?

No. Each major carrier maintains its own FSC table, which differs in the trigger price (where the FSC first applies), the per-step increment, and any cap. As of March 2026, FSC rates among major carriers at the same diesel price can vary by 3–6 percentage points. This is why comparing total cost (base rate + FSC) rather than base rate alone is critical when selecting a carrier.
