Understanding Fuel Surcharges

What is a Fuel Surcharge?

A fuel surcharge (FSC) is an additional fee added to freight rates to offset fuel price volatility. It's typically calculated based on DOE national diesel averages and a baseline price.

Standard FSC Formula

FSC = (Current Price - Baseline Price) × (Miles ÷ MPG). This ensures carriers are compensated for fuel cost increases above the baseline.

Need to explain FSC changes to shippers?

Use this calculation as the pricing basis, then pair it with a clear explanation of the diesel reference, baseline, effective date, and whether linehaul changed separately. Read our fuel surcharge communication guide for freight brokers for a practical 2026 playbook.
