What is Fuel Surcharge (FSC)
Fuel surcharge (FSC) is additional compensation paid to truck drivers when diesel prices exceed the baseline price agreed in shipping contracts. Our calculator helps you quickly determine your earnings using the industry-standard formula.

How to Calculate Fuel Surcharge
Step-by-step guide to mastering FSC calculations
Find Your Contract Base Fuel Price
Where to Look
Shipping Contract: "base fuel price" or "fuel surcharge baseline"
Rate Confirmation: Fuel surcharge section
Broker Agreement: Addendum or fuel surcharge clause
Common Base Prices
$1.15/gallon: Older contracts or aggressive shippers
$1.25/gallon: Most common industry standard
$1.35/gallon: Higher base used by premium carriers
Get Current Diesel Price for FSC Calculation
You need the current diesel price for your area or route. Most contracts specify whether to use local, regional, or national average prices.
Reliable Fuel Price Sources
EIA - Official U.S. government data
ProMiles - Industry-standard for trucking fuel prices
OOIDA - Owner-operator focused pricing
Truck Stops - TA/Petro, Pilot/Flying J, Love's posted prices
Important Notes
Check Contract Terms: Some contracts specify which price source to use
Weekly vs Daily Updates: Understand how often prices are updated in your agreement
Apply the Fuel Surcharge Formula
Use the industry-standard formula: (Current Price - Base Price) ÷ Your MPG = FSC per Mile
Real Example Calculation
Current Diesel Price: $3.45/gal
Contract Base Price: $1.25/gal
Your Truck's MPG: 6.5 MPG
Calculation: ($3.45 - $1.25) ÷ 6.5 = $0.338/mile
For 1,200 Mile Trip: $0.338 × 1,200 = $405.60
Seasonal Fuel Price Trends
Understanding seasonal fuel price patterns helps truck drivers and fleet managers anticipate fuel surcharge changes and plan routes accordingly.
Spring
March - May
Trend: Gradual price increase
Driving Season: Begins ramping up
Typical FSC: $0.25-$0.35/mile
Lock long-term contracts early
Summer
June - August
Trend: Peak driving season prices
Hurricane Risk: Gulf Coast volatility
Typical FSC: $0.35-$0.50/mile
Highest earning potential
Fall
September - November
Trend: Moderate decline begins
Harvest Season: Agricultural freight peaks
Typical FSC: $0.30-$0.40/mile
Good balance of rates/costs
Winter
December - February
Trend: Lowest annual prices
Heating Oil Demand: Can affect diesel
Typical FSC: $0.20-$0.30/mile
Focus on efficiency gains
State-by-State Fuel Surcharge Variations
Fuel prices vary significantly by state due to taxes, regulations, and regional supply chains. Smart route planning considers these variations for maximum fuel surcharge optimization.
Highest Fuel Cost States
California: $4.50-$5.00/gal avg
Hawaii: $4.80-$5.20/gal avg
Washington: $4.20-$4.60/gal avg
Oregon: $4.10-$4.50/gal avg
New York: $3.80-$4.20/gal avg
Higher fuel surcharge potential, but verify contract terms for regional pricing.
Lowest Fuel Cost States
Texas: $3.00-$3.40/gal avg
Louisiana: $3.10-$3.50/gal avg
Oklahoma: $3.15-$3.55/gal avg
Arkansas: $3.20-$3.60/gal avg
Mississippi: $3.25-$3.65/gal avg
Lower surcharge rates, but reduced fuel costs may offset difference.
Special Considerations
CARB States: California emissions requirements
Winter Blend: Northern states Oct-Apr
Hurricane Zones: Gulf Coast price volatility
Refinery Locations: Texas/Louisiana advantages
Border Effects: Mexico/Canada proximity
Plan routes through lower-cost states when possible for fuel savings.

Real-World Calculation Examples
Practical fuel surcharge calculations for different route types
Short Haul
Dallas to Houston
Distance: 240 miles
Current Fuel: $3.25/gallon
Base Price: $1.25/gallon
Truck MPG: 7.2 MPG
FSC per Mile: ($3.25-$1.25) ÷ 7.2 = $0.278
Total FSC: $66.72
Long Haul
Los Angeles to Miami
Distance: 2,750 miles
Current Fuel: $3.65/gallon
Base Price: $1.20/gallon
Truck MPG: 6.8 MPG
FSC per Mile: ($3.65-$1.20) ÷ 6.8 = $0.360
Total FSC: $990.00
Regional Route
Chicago to Denver
Distance: 920 miles
Current Fuel: $3.45/gallon
Base Price: $1.30/gallon
Truck MPG: 6.5 MPG
FSC per Mile: ($3.45-$1.30) ÷ 6.5 = $0.331
Total FSC: $304.52
✦Key Takeaways
- ✓
Standard FSC Formula: (Current Fuel Price - Base Price) ÷ MPG = Fuel Surcharge per Mile. Base prices typically range $1.15-$1.35/gallon.
- ✓
Seasonal Patterns: Summer (June-Aug) highest FSC $0.35-$0.50/mile, Winter (Dec-Feb) lowest $0.20-$0.30/mile. Plan loads accordingly.
- ✓
State Price Variations: California ($4.50-$5.00/gal) vs Texas ($3.00-$3.40/gal). Route planning affects surcharge significantly.
- ✓
Negotiation Tactics: Push for lower base price ($1.15-$1.20), zero floor clause, weekly updates, and regional pricing instead of national averages.
- ✓
Update Frequency: Most contracts update weekly (Mondays). Track fuel trends to anticipate changes and time loads for maximum profitability.
- ✓
MPG Impact: Better MPG reduces FSC compensation but saves more in actual fuel costs. 6.0 MPG = $0.367/mile vs 7.0 MPG = $0.314/mile FSC.
- ✓
Historical Context: COVID low $1.87/gal (2020), Peak $5.81/gal (2022), Current stabilization $3.20-$4.50/gal (2023-2025).
