Fuel Surcharge (FSC).
Variable line item on a freight bill adjusting compensation for fuel price fluctuations; calculated from the DOE national diesel price benchmark.
What it is
A fuel surcharge (FSC) is a variable line item that compensates the carrier for fuel-price changes since the contract rate was set. Standard industry practice is to base the FSC on the weekly DOE/EIA national average diesel price — published every Monday by the US Energy Information Administration.
The common formula is a fixed cents-per-mile escalator above a baseline diesel price. A representative example: $0.04 per mile additional FSC for every $0.06 per gallon that diesel exceeds a $3.00 baseline. Spot-market loads usually have FSC baked into the all-in rate (a single number, no separate FSC line). Contract carriers on dedicated lanes almost always have explicit FSC schedules built into the master agreement.
FSC protects the carrier from fuel-cost volatility between when contract pricing is set and when the load actually runs. On accounting treatment, FSC paid out is generally part of freight revenue rather than a separate revenue category.
Why it matters for trucking finance
FSC is one of the cleanest accessorials to collect — it's automatic on contracted lanes and standardized in spot-market quoting. On a single-truck operation, FSC can mean $500–$2,000 in monthly revenue depending on fuel price level and lane mix.
Carriers who don't enforce or audit FSC against the published DOE baseline leave revenue on the table — brokers occasionally underpay FSC when fuel spikes and aren't always proactive about updating. Factoring companies treat FSC as part of revenue for advance-rate calculations, which means clean FSC tracking directly supports cash flow. Lenders evaluating contracted-lane carriers also look at FSC schedules during underwriting — a strong, indexed FSC clause reduces fuel-volatility risk on projected revenue.
