Fuel Surcharge
A fuel surcharge (FSC) is a variable fee added to freight invoices to offset the carrier's fluctuating diesel costs. It is typically calculated as a percentage of the base rate and adjusted weekly based on published fuel price indices. For example, a carrier may set its FSC at 28 percent of the line haul rate when diesel averages $4.00 per gallon nationally.
Why it matters
Fuel surcharges can add 20 to 30 percent or more to a base freight rate and are highly unpredictable, making budgeting difficult and often obscuring the true all-in cost of a shipment. Over a 12 month period, FSC fluctuations alone can swing total freight spend by 8 to 12 percent for shippers with no fuel hedging strategy.
When to use it
Account for fuel surcharges any time you are comparing carrier quotes. Always look at the all-in rate, not just the base line haul, to make accurate cost comparisons. When running a carrier RFP, request that all bidders use the same fuel index and base price to ensure apples to apples evaluation.
How Warp thinks about it
Warp's per-pallet pricing is all-inclusive. Fuel costs are baked in, not tacked on as a variable surcharge, so shippers know exactly what they'll pay without needing to track weekly FSC indices. This transparent pricing model extends across all 1,500+ active lanes in Warp's network of 9,000+ cargo vans and box trucks.
