Fuel Surcharge (FSC) Calculator
Compute standard commercial shipper fuel surcharges based on national weekly diesel price benchmarks, base peg rates, and fleet MPG divisors.
Core Mathematical Formula: FSC per Mile = (Current Diesel Price - Base Fuel Peg) ÷ Fleet MPG. Total FSC = FSC per Mile × Loaded Miles.
Standard truckload freight contracts tie surcharges directly to the weekly Department of Energy / EIA average diesel index. Benchmark table calculated at baseline MPG:
| EIA Diesel Price | Fuel Spread | FSC Rate (mile) | 500-Mile FSC | 1,000-Mile FSC |
|---|---|---|---|---|
| $3.40/gal | $2.15 | +$0.331/mile | $165.38 | $330.77 |
| $3.60/gal | $2.35 | +$0.362/mile | $180.77 | $361.54 |
| $3.80/gal | $2.55 | +$0.392/mile | $196.15 | $392.31 |
| $4.00/gal ★ | $2.75 | +$0.423/mile | $211.54 | $423.08 |
| $4.20/gal ★ | $2.95 | +$0.454/mile | $226.92 | $453.85 |
| $4.40/gal | $3.15 | +$0.485/mile | $242.31 | $484.62 |
| $4.60/gal | $3.35 | +$0.515/mile | $257.69 | $515.38 |
| $4.80/gal | $3.55 | +$0.546/mile | $273.08 | $546.15 |
| $5.00/gal | $3.75 | +$0.577/mile | $288.46 | $576.92 |
Understanding the Commercial Fuel Surcharge Formula: Peg-Rate vs. Zero-Base
Carriers and brokers agree on a baseline fuel peg (typically $1.20 to $1.50/gal) already absorbed in the base linehaul. As diesel fluctuates above this peg, the shipper pays the incremental variance:
The base linehaul rate covers solely equipment, driver labor, and operating overhead. The shipper pays 100% of fuel costs directly based on actual pump price:
Used predominantly in dedicated private fleet contracts and long-term utility hauling.
Truckload (TL) vs. Less-Than-Truckload (LTL) & Canadian FCA Standards
Billed on loaded highway miles (e.g. +$0.438/mile). Every Monday at 4:00 PM EST, the carrier updates billing to mirror the new EIA national average.
LTL carriers (Old Dominion, Estes, Saia) publish weekly fuel surcharge matrix tables where diesel prices trigger a percentage multiplier (e.g., 28.5% of gross freight charge).
Administered by the Freight Carriers Association (FCA) based on Natural Resources Canada (NRCan) regional rack pricing in cents per liter (cpl).
4-Step Checklist for Verifying Fuel Surcharges on Broker Rate Confirmations
Confirm Itemized Separation: Ensure the rate confirmation explicitly lists Base Linehaul and Fuel Surcharge as separate line items rather than a flat "all-in" rate.
Verify Base Peg & MPG: Check that the contract states the baseline fuel peg ($1.20 or $1.25) and agreed MPG divisor (6.0 to 6.5 MPG) to avoid arbitrary broker markdowns.
Use EIA Monday 4 PM Index: Confirm which day's diesel index governs multi-week dedicated runs. Standard contracts update weekly on Tuesday morning following Monday's release.
Watch for Deadhead Fuel Gaps: Surcharges typically apply only to loaded billable miles. Factor empty deadhead fuel expenses into your baseline linehaul negotiation.
All calculations execute strictly according to standard federal transportation benchmarks and transparent mathematical constants with zero hidden padding.
Your contract specifies a standard $1.25/gallon base fuel peg and a 6.5 MPG baseline. The weekly EIA diesel index reports $4.10/gal. You haul an 850-mile load.
US DOT vs. Transport Canada Standards Comparison
US Interstate: Standard 5-axle semi is capped at 80,000 lbs (36,287 kg) gross, with 34,000 lbs tandem and 20,000 lbs single axle limits under Federal Bridge Formula B.
Canada (NSC/MOU): Standard tandem is permitted up to 17,000 kg (37,478 lbs). Canadian B-Train Super-B configurations gross up to 63,500 kg (140,000 lbs) under Ontario SPIF and Western Canadian regulations.
US FMCSA: Max 11 hours driving within a 14-hour on-duty window, followed by 10 consecutive hours off-duty/sleeper berth, and a 70-hour / 8-day rolling cycle.
Canada NSC Standard 9: Max 13 hours driving within a 14-hour on-duty window, requiring 10 hours daily off-duty, operating under Cycle 1 (70h/7d) or Cycle 2 (120h/14d).
US EIA Benchmark: Tied to the weekly US Energy Information Administration national on-highway diesel index, billed in $/mile.
Canadian FCA / NRCan: Freight Carriers Association (FCA) of Canada weekly diesel rack pricing, pegged in Canadian cents per liter (cpl) and billed in $/km or % surcharge.
