Calculating FedEx Freight rates involves several key factors that determine the final cost of shipping your goods. Unlike standard parcel services, freight shipping is designed for larger, heavier shipments that exceed typical parcel size and weight limits. This calculator provides an *estimated* rate, as actual prices can vary based on specific surcharges, fuel costs, discounts, and your negotiated contract rates with FedEx.
Key Factors Influencing Your Rate:
Weight: The total actual weight of your shipment in pounds (lbs). Heavier shipments generally cost more.
Dimensions (Cubic Feet): The total volume of your shipment. FedEx Freight uses a dimensional weight (DIM weight) factor to account for space taken up in the truck. If the DIM weight (calculated from length, width, and height) is greater than the actual weight, you will be charged based on the DIM weight. This calculator simplifies it by asking for total cubic feet.
Origin and Destination ZIP Codes: The distance between the origin and destination significantly impacts transit time and cost. Rural or remote locations might incur additional charges.
Service Type: FedEx offers various freight services. "FedEx Freight Priority" is faster but more expensive, while "FedEx Freight Economy" is more budget-friendly with longer transit times. "FedEx Ground Economy" is suitable for lower-weight, less time-sensitive shipments.
Freight Class: This is a standardized classification system (from 50 to 500, but commonly used up to 85 for many LTL shipments) used in the United States by the National Motor Freight Traffic Association (NMFTA) to categorize commercial goods based on density, stowability, handling, and liability. The higher the freight class, generally the higher the cost, reflecting higher risk or lower density.
Fuel Surcharges: Fluctuating fuel prices are added as a percentage surcharge.
Accessorial Charges: These are extra services like liftgate service, inside delivery, residential delivery, or delivery to a limited access location, which will add to the base rate.
How the Estimate is Calculated (Simplified):
This calculator uses a simplified model. A base rate is determined by factors like distance (derived from ZIP codes), weight, and freight class. This base rate is then adjusted by the chosen service type and potentially a dimensional weight factor if the volume is significant relative to the weight. Please note that this is a simplified estimation and does not include all potential surcharges or negotiated discounts.

// — Simplified Rate Calculation Logic —
// This is a highly simplified model. Real FedEx rates are complex and depend on many variables.
// We'll simulate a base rate per pound influenced by freight class and distance,
// then apply service type multipliers.
var baseRatePerLb = 0.50; // Base rate per pound, arbitrary starting point
var classMultiplier = 1 + (freightClass / 100); // Higher class increases rate
var distanceFactor = 1; // Simplified distance factor
// Very basic distance estimation (more sophisticated would use zip code lookup/databases)
var originFirstDigit = parseInt(originZip.charAt(0));
var destinationFirstDigit = parseInt(destinationZip.charAt(0));
if (Math.abs(originFirstDigit – destinationFirstDigit) > 4) {
distanceFactor = 1.3; // Longer distance
} else if (Math.abs(originFirstDigit – destinationFirstDigit) < 2) {
distanceFactor = 0.9; // Shorter distance
}
var baseRate = weight * baseRatePerLb * classMultiplier * distanceFactor;
// Apply service type adjustments
var serviceMultiplier = 1.0;
if (serviceType === "FDXG") {
serviceMultiplier = 0.8; // Ground Economy is typically cheaper
} else if (serviceType === "FXF") {
serviceMultiplier = 1.5; // Priority is more expensive
} else if (serviceType === "FXFE") {
serviceMultiplier = 1.1; // Economy is slightly more than base
}
// Consider dimensional weight (simplified – assumes a factor)
// A common DIM factor for freight might be 15-20 lbs per cubic foot. Let's use 18.
var dimWeight = dimensions * 18;
var chargeableWeight = Math.max(weight, dimWeight);
var estimatedRate = chargeableWeight * baseRatePerLb * classMultiplier * distanceFactor * serviceMultiplier;
// Add a small base fee for handling/processing
var baseProcessingFee = 50;
estimatedRate += baseProcessingFee;
// Simulate fuel surcharge (e.g., 15% of subtotal)
var fuelSurchargeRate = 0.15;
estimatedRate += estimatedRate * fuelSurchargeRate;
// Ensure the result is formatted nicely
var formattedRate = estimatedRate.toFixed(2);
resultDiv.innerHTML = "Estimated Rate: $" + formattedRate + "";
resultDiv.style.color = '#28a745'; // Success green
resultDiv.style.borderColor = '#28a745'; // Success green border
