Understanding the DOE Fuel Surcharge Standard

The Department of Energy (DOE) National Average Diesel Price serves as the benchmark for trucking contracts across North America. Surcharges are computed above a negotiated baseline "peg" (typically $1.20 to $2.50 per gallon).

For every step increase (often $0.05 or $0.06/gal), carriers assess an incremental 1¢ per loaded mile. When retail fuel outpaces the standard formula efficiency (e.g., in low-MPG heavy haul or heavy deadhead routes), unrecovered fuel expenses erode linehaul margins rapidly.

Mitigating Kalshi & Spot Escalation Volatility

With market predictions pricing diesel upwards of $7.40/gallon, standard quarterly surcharge reviews fail to protect cash flow. Best practices include:

• Weekly Indexing: Pegging FSC adjustments to the Monday DOE release rather than monthly averages.
• Deadhead Factor Allocation: Incorporating unladen repositioning miles into the billable linehaul baseline.
• Continuous Curve vs. Step Tiers: Transitioning from $0.05 step intervals to direct exact-cent floating recovery formulas.

How is the carrier's Net Fuel Gap calculated?

The Net Fuel Gap reflects the difference between the actual fuel expense incurred across all driven miles (loaded + deadhead) and the fuel surcharge collected strictly on billed loaded miles. If your vehicle achieves 6.2 MPG, fuel costs you $1.047/mile at $6.49/gal. If the contract pays an FSC of $0.80/mile on loaded miles only, the remaining $0.247/mile plus 100% of empty deadhead fuel must be absorbed by the base rate.

Can this tool be used for gasoline-powered commercial fleets?

Yes. By switching the fuel selector to Unleaded Regular Gasoline and tuning your vehicle's specific MPG (such as 10 to 18 MPG for transit vans or 3/4-ton pickups), the workbench accurately models gas fleet recovery and lane margins against regional gasoline price shocks.

What is the difference between CPM step vs. Percentage Surcharge?

Cents-per-mile (CPM) formulas directly match fuel consumption to distance traveled, providing fair compensation regardless of lane density. Percentage surcharges scale with the freight rate itself, which can over-compensate on high-rate short hauls while drastically under-recovering on cross-country loads.
