Calculate LTL and FTL freight costs using real industry math — freight class, CWT rates, carrier discounts, fuel surcharges, and accessorials. Built for shippers, brokers, and procurement teams.
LTL rates are based on CWT (hundredweight — per 100 lbs). Your freight class is determined by density (weight divided by cubic feet). The carrier applies a tariff rate per CWT based on your class and weight break, then applies your contracted discount (typically 70–90% off tariff), adds a fuel surcharge (usually 18–28% of discounted linehaul), and tacks on any accessorials. This calculator runs all of that automatically.
Freight class is a number from 50 to 500 assigned by the NMFC (National Motor Freight Classification). It's based primarily on density — pounds per cubic foot. Denser, heavier freight gets a lower class (50–85) and a lower rate. Lighter, bulkier freight gets a higher class (125–500) and costs more per pound. Enter your pallet dimensions and weight and the tool calculates it automatically.
LTL is typically cheaper for shipments under 10,000 lbs or fewer than 8–10 pallets. FTL becomes cost-competitive when your freight fills 60% or more of a 53' trailer, when transit time or product handling risk is a concern, or when you're shipping hazardous materials. Use the comparison tab to model both and see which wins for your specific shipment.
Yes. The LTL panel includes a Carrier Rate Override toggle. Check it and enter your contracted CWT rate directly. The tool bypasses the benchmark table and applies your actual rate — fuel surcharge and accessorials still stack on top normally. For FTL, use the Custom Rate option in the Rate Type selector.
