Intermodal vs Truckload Savings Calculator — Rail vs Truck Cost
Calculate savings from switching long-haul freight to intermodal rail. Compare cost per mile, transit time impact, and annual net savings.
🚂 Intermodal vs Truckload Savings Calculator
How to Use This Calculator
- Enter lane distance and annual loads — intermodal is most competitive on lanes over 750 miles with consistent volume.
- Get intermodal quotes — contact BNSF, UP, CSX, or NS intermodal desks, or work with an IMC (intermodal marketing company).
- Factor transit time impact — enter shipment value and carrying rate to account for extra transit days' inventory cost.
Worked Example
1,500-mile lane, 100 loads/year, $2.80 OTR vs $2.10 intermodal, 2 vs 4 transit days, $50K shipment.
- Freight saving: $0.70 × 1,500 × 100 = $105,000
- Transit carry cost: $50K × 25% ÷ 365 × 2 × 100 = $685
- Net saving: $104,315/year
The 2-day transit extension costs less than 1% of the freight saving. On lanes over 750 miles with consistent volume, intermodal is almost always worth the switch.
Frequently Asked Questions
Under 500 miles (drayage erodes savings), time-critical freight, temperature-controlled loads without reefer container availability, and irregular volume. Also avoid when origin/destination are far from intermodal ramps.
Drayage is the truck leg between shipper/consignee and the rail ramp — adds $150–$500 each way. Shippers within 50 miles of a major ramp get the best intermodal economics.
