Less Than Truckload (LTL) freight shipping is a popular and cost-effective solution for businesses that don't have enough goods to fill an entire truck. Instead of paying for an entire trailer, LTL allows you to pay for only the space your shipment occupies. However, calculating LTL freight rates can seem complex due to several factors that influence the final price. This guide will break down the key components involved in determining LTL freight costs.
Key Factors Influencing LTL Freight Rates
Freight Class: This is arguably the most crucial factor. The National Motor Freight Classification (NMFC) system assigns a class (from 50 to 400) to all goods based on their density, stowability, handling, and liability. Higher classes generally mean higher rates.
Weight: The total weight of your shipment is a primary cost driver. LTL carriers charge based on weight tiers, with heavier shipments typically costing more.
Distance: The distance the shipment needs to travel significantly impacts the rate. Longer hauls are generally more expensive.
Fuel Surcharge: Fuel costs are variable, so carriers implement a fuel surcharge percentage that fluctuates based on market prices. This is usually a percentage of the base rate.
Accessorial Charges: These are additional services beyond standard pickup and delivery. Common examples include liftgate service, inside delivery, residential delivery, limited access locations, and hazardous materials handling.
Minimum Charges: Most LTL carriers have a minimum charge per shipment to cover administrative and handling costs, even for very light shipments.
Dimensional Weight (or Cubic Weight): If your shipment is bulky but light, carriers may charge based on its volume rather than its actual weight. This is calculated by dividing the total cubic inches of the shipment by a dimensional factor (often 194). The higher of the actual weight or dimensional weight is then used for pricing.
How the Calculator Works
Our LTL Freight Rate Calculator simplifies this process. You'll input details about your shipment, and the calculator will estimate a rate based on the factors listed above. By understanding these components, you can better negotiate rates and manage your shipping budget effectively.

// Calculate dimensional weight
var cubicVolume = (length * width * height) / 6102.37; // Convert cm^3 to cubic feet, then to a common dimensional factor
var dimensionalWeight = cubicVolume * 1.3; // A common dimensional factor for LTL; this can vary by carrier. For simplicity, we use 1.3 lbs/cubic foot equivalent.
// Adjusting for metric input: 1 cubic meter = 1,000,000 cm^3. Let's assume a dimensional factor similar to international standards where a 1m^3 box might be charged as 167kg.
// Or, more commonly in LTL, it's often based on lbs per cubic foot. Let's convert inputs to feet for a more standard calculation, or adapt a metric dimensional factor.
// For simplicity and to keep it in metric, let's use a common metric dimensional factor for LTL where 1 cubic meter is often equated to 167 kg.
var volumeInCubicMeters = (length * width * height) / 1000000; // cm^3 to m^3
var dimensionalWeightMetric = volumeInCubicMeters * 167; // Using 167 kg/m^3 as a common example dimensional factor
var chargeableWeight = Math.max(actualWeight, dimensionalWeightMetric);
// Calculate base freight cost
var baseFreightCost = chargeableWeight * baseRatePerKg * (distance / 1000); // Rough proportionality by distance
// Calculate fuel surcharge
var fuelSurchargeAmount = baseFreightCost * (fuelSurchargePercent / 100);
// Calculate total estimated rate
var totalRate = baseFreightCost + fuelSurchargeAmount + accessorialCharges;
// Apply a minimum charge (example: $100)
var minCharge = 100;
totalRate = Math.max(totalRate, minCharge);
document.getElementById("estimatedRate").innerText = "$" + totalRate.toFixed(2);
