Freight Cost Per Ton-Mile & Intermodal Shipping Calculator

Transportation Logistics & Freight Procurement: The Universal Ton-Mile Standard

The ton-mile is the fundamental standardized unit of physical output in transportation economics, equal to moving one ton of freight one mile:

• Modal Cost Hierarchies:

• Inland River Barge: 0.02–0.05 / ton-mile (cheapest, bulk commodities).

• Class I Railroad: 0.04–0.08 / ton-mile (high fuel efficiency for long hauls >600 miles).

• Truckload (FTL): 0.10–0.20 / ton-mile (fast, point-to-point door delivery).

• Less-Than-Truckload (LTL): 0.30–0.65 / ton-mile (multi-terminal cross-docking).

• Air Cargo: 1.20–3.50+ / ton-mile (high speed, urgent perishables and electronics).

• Mode Shift Optimization: Converting long-haul lanes (>800 miles) from full truckload to rail intermodal typically cuts freight spend by 15%–25% and reduces carbon emissions by up to 60%–70%.

How to Use This Calculator

Enter your Cargo Shipment Weight (US Short Tons [2,000 lbs]) (e.g. 22 (e.g. 44,000 lbs = 22 tons)), Transit Haul Distance (Miles) (e.g. 850), Total Linehaul Freight Cost ( Base + Fuel Surcharge) (e.g. 2,450), and Freight Transportation Mode Benchmark — choose from Dry Van / Reefer Truckload (FTL: ~0.10–0.20 / ton-mile), Less-Than-Truckload (LTL: ~0.30–0.65 / ton-mile), Class I Railroad Intermodal (Rail: ~0.04–0.08 / ton-mile).

The Formula

Freight Transportation \& Modal Economics equations:

Total Ton-Miles = Cargo Weight (Tons) × Transit Haul Distance (Miles)

Cost Per Ton-Mile (\/ton-mile) = (Total Freight Cost (\)) / (Total Ton-Miles)

Cost Per Vehicle Mile (\/mile) = (Total Freight Cost) / (Transit Distance (Miles))

Cost Per Hundredweight (CWT) = (Total Freight Cost) / (Weight (Tons) × 20)

Freight CO_2e Emissions (kg) = (Total Ton-Miles × Mode Emission Factor (g CO_2/ton-mile)) / (1,000)

Worked Example

For example, moving a 22.0 short ton (44,000 lbs) full truckload shipment over 850 miles at a total cost of \2,450.00: The total output is . The Cost Per Ton-Mile is \. The vehicle mile rate is \2.88/mile, the hundredweight rate is \5.57/cwt, generating approximately 2,805 kg CO2e emissions.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
