Free LTL Freight Class Calculator

Enter your shipment dimensions and weight below to estimate freight class, density, and cubic feet.

This calculator gives a density-based freight class estimate. Final class may vary by NMFC code, commodity type, carrier review, handling, stowability, and liability.

Use our free LTL freight class calculator to quickly estimate your shipment’s freight class using pallet dimensions and total weight. The tool calculates shipment density, cubic feet, and estimated freight class so you can better understand how LTL carriers may classify your freight.

This estimate is helpful for planning, quoting, and comparing shipments, but it should not replace official NMFC classification or carrier confirmation.

What is a Freight Class?

Freight class is a standardized shipping category defined by the NMFC (National Motor Freight Classification). It helps US carriers determine shipping costs based on four factors: density, stowability, handling, and liability. Lower classes like Class 50 are dense and cheaper to ship, while higher classes like Class 500 are for light, fragile items. Using a professional and easy LTL Class Calculator ensures your shipment is categorized correctly before it leaves the dock.

Standard 18-Tier NMFC Freight Class Density Chart

Use the following reference chart or NMFC Freight Class list to estimate your freight class based on pounds per cubic foot (PCF). Note: stowability, handling, and liability also affect the final NMFC classification.

Density (pcf)	Freight Class

35 – 50	55
30 – 35	60
22.5 – 30	65
15 – 22.5	70
13.5 – 15	77.5

How to Calculate LTL Density with this ltl freight class calculator in 2026

How to Calculate Freight Class for Shipping? To find your shipment’s density, multiply the length, width, and height of your pallet in inches and divide by 1,728 to get the cubic feet. Then, divide the total weight by the cubic feet. Accurate density calculation is the #1 way to avoid costly carrier re-bills and unexpected freight charges. This calculator estimates freight class based on shipment density. Final classification may also depend on NMFC code, stowability, handling, and liability.

Understanding PCF (Pounds per Cubic Foot)

PCF is the standard measurement of Freight Density. In the LTL (Less-Than-Truckload) industry, your freight class is primarily determined by how much space your shipment occupies in relation to its weight.

How PCF Impacts Your Shipping Cost:

• High PCF (Compact/Heavy): Items like machinery or steel have a high PCF, resulting in a Lower Freight Class (e.g., Class 50-70) and lower rates.
• Low PCF (Bulky/Light): Items like ping-pong balls or un-assembled furniture have a low PCF, resulting in a Higher Freight Class (e.g., Class 250-500) and higher rates.

Calculation Formula: Density (PCF) = Weight (lbs) ÷ Cubic Feet (ft³)

Standard Pallet Dimensions and Shipping Costs

Most US freight moves on a standard 48″ x 40″ pallet. The density of a standard pallet significantly impacts your shipping class. For example, a 700 lbs pallet at 48″ height results in a density of 13.13 lb/cu ft, which typically falls into Class 85. Knowing your class allows you to get accurate quotes from carriers and avoid the “re-classification” fees that many shippers face when they guess their freight class.

Why You Need an LTL Freight Class Calculator

When creating LTL shipping plans, then first knowing your LTL shipping class is critical for accurate pricing. The mistakes in the weight, dimensions, or pallet density can lead to reclassification fees or unexpected costs. This LTL shipping calculator provides shipping class, density, and volume, giving small business owners and e-commerce sellers the exact numbers to plan shipments efficiently for the platforms like  Amazon FBA, AWD, Shopify, Etsy, Walmart, or shipping carriers like FedEx, UPS, DHL, XPO, SAIA, R+L Carriers, Estes, and third-party booking sites such as FreightQuotes, UniShippers, Freightos, etc.

How this LTL Class Calculator Works

1. Enter your pallet or package dimensions (length, width and height) in inches with the order Length x Width x Height.
2. Enter the total shipment weight in pounds (lbs).
3. Click the calculate button to see freight class first, followed by density and volume.
4. Use these numbers to create accurate shipping plans, book LTL shipments, or generate labels on carrier websites and third-party platforms.

Why Freight Class Matters for Your Business

Freight class determines the cost of LTL shipments and helps prevent costly surprises. High-density, compact shipments usually have lower LTL classes and cost less, while low-density, bulky shipments have higher classes. Knowing the correct NMFC class allows small businesses, virtual assistants, and e-commerce sellers to optimize packaging, reduce shipping expenses, and improve order fulfilment efficiency. This pallet freight calculator is good for your business.

Tips to Optimize Your Shipment for Cost Savings

• Pack efficiently: Reduce empty space to increase density and lower LTL freight class.
• Select the right pallet size: Avoid oversized pallets that increase volume unnecessarily.
• Use sturdy packaging: Prevents movement and handling issues that could affect class.
• Enter precise dimensions and weight: Accuracy prevents reclassification fees and ensures smooth processing on Amazon, Shopify, Etsy, Walmart, or with carriers.
