What Is A Freight Density Calculator?
A Freight Density Calculator is an online tool that helps shippers and carriers calculate a shipment’s density to determine its freight class. The tool asks for the shipment’s dimensions, weight, origin, and destination zip codes and uses this information to calculate the shipment’s pounds per cubic foot (PCF).
How Is LTL Class Density Calculated?
LTL (Less Than Truckload) class density is calculated using a freight density calculator, which applies the same formula used for general freight density:
Freight Density (lbs/ft³) = Weight of Shipment (lbs) / Total Cubic Feet of Shipment
To calculate the total cubic feet of a shipment, you multiply its length, width, and height in inches, then divide the result by 1728 (the number of cubic inches in a cubic foot). Utilizing a freight density calculator ensures accuracy and consistency in determining this value.
The LTL carrier typically uses a freight density calculator to measure the shipment’s density before assigning a freight class. The calculated freight density plays a crucial role in determining the appropriate freight class, which considers the product’s density, stowability, handling, and liability.
The LTL class density is a key factor in establishing the shipping cost for an LTL shipment. Higher freight density generally results in a higher freight class, leading to increased shipping costs. Besides freight density, LTL carriers also factor in the distance, origin, destination, and other relevant variables when calculating shipping costs.
It’s important to note that LTL carriers may have specific requirements and formulas for calculating freight density. Using a freight density calculator aligned with the carrier’s guidelines ensures that your shipment is accurately classified and avoids unexpected charges.
The NMFC number, a four-digit code assigned to each commodity or product, is used in conjunction with the freight density calculated by the freight density calculator to determine the appropriate freight class. The NMFC number, based on the product’s characteristics, helps assign a freight class ranging from 50 to 500. A higher freight class typically results in a higher shipping cost.
In general, commodities with a lower NMFC number but higher freight density, as determined by the freight density calculator, are assigned to a higher freight class, resulting in higher shipping costs. For instance, a shipment of bricks would have a higher NMFC number and freight density, leading to a higher freight class and shipping cost than a shipment of pillows, which would have a lower NMFC number and freight density.
In summary, freight class density and NMFC number are crucial factors in determining the cost of LTL shipping. The freight density calculator measures the weight of the shipment in relation to its volume, while the NMFC number is a standardized code used to classify commodities based on their characteristics. These factors together determine the appropriate freight class for the shipment, influencing the overall shipping cost.
NMFC-Based Freight Class
The National Motor Freight Traffic Association (NMFTA), a nonprofit membership organization of motor carriers, developed the National Motor Freight Classification® (NMFC) system to assign freight classes to various commodities. The freight density calculator is essential in this process, ensuring that the density calculations are precise and consistent with NMFC standards.
Density-Based Freight Class
In some cases, density, rather than the NMFC number, will determine a shipment’s freight class. This occurs under two circumstances:
1. When using a density-based carrier.
2. When the NMFC for the shipped item is Not Otherwise Indicated (NOI). This might happen when shipping multiple items with different freight classes in the same crate.
Understanding how to use a freight density calculator effectively is vital, as the freight density of an object measures its compactness, typically expressed in pounds per cubic foot (PCF). The relationship between freight density and class is significant, and using a reliable freight density calculator ensures that shipments are accurately classified, leading to more predictable shipping costs.
How Do You Calculate Freight Density?
To calculate freight density:
- Measure the length, width, and height of your shipment in inches.
- Multiply these dimensions to find the cubic inches of your shipment.
- Convert cubic inches to cubic feet by dividing the total cubic inches by 1,728 (since 1 cubic foot equals 1,728 cubic inches).
- Divide the total weight of the shipment (in pounds) by the cubic feet to get the density in pounds per cubic foot (PCF).
For example:
- Shipment Dimensions: 48″ x 40″ x 24″
- Total Weight: 800 lbs
- Cubic Inches: 48 x 40 x 24 = 46,080 cubic inches
- Cubic Feet: 46,080 / 1,728 = 26.67 cubic feet
- Density: 800 lbs / 26.67 cubic feet = 30 PCF

Freight density directly impacts pricing in LTL shipping, as carriers charge based on the freight class, which is determined by density. Higher density goods typically incur lower rates.
Higher density freight allows for full utilization of a truck's weight capacity, optimizing shipping costs. Low-density freight may lead to "cubing out" before reaching the truck's weight limit, resulting in higher costs per unit.
In intermodal transport (using multiple modes of transport, such as rail and truck), freight density affects container loading efficiency. High-density goods maximize container space, lowering per-unit costs.
Similar to other modes, the density of goods affects how much can be packed into a container. Higher density freight maximizes the space within a container, reducing overall shipping costs.
Services like refrigerated trucking are affected by freight density, as denser loads may require more energy to maintain temperature, affecting operational costs.
For small packages, density affects dimensional weight pricing, which determines the cost based on the space a package occupies rather than its actual weight.
Dense freight might increase the weight-to-volume ratio, potentially maximizing the efficiency of railcars, which are built to carry heavy loads over long distances.
Air freight is highly sensitive to freight density because airlines calculate charges based on either the actual weight or the volumetric weight, whichever is higher.
Guaranteed competitive pricing every time you ship.
Three Step Freight Density Calculator Equation
The Three-Step Freight Density Equation used in FreightCenter’s Freight Density Calculator is a simple and effective way to calculate the density of your shipment. Here are the three steps involved:
Step 1: Measure the dimensions of your shipment in inches (length, width, and height).
Step 2: Multiply the dimensions together to get the total cubic inches of your shipment.
Step 3: Divide the total weight of your shipment by the total cubic inches to get the pounds per cubic foot (PCF) or density of your shipment.
The equation is as follows:
Density (PCF) = Weight of Shipment (lbs) ÷ Total Cubic Inches of Shipment × 1728
The result of the equation gives you the density of your shipment in pounds per cubic foot (PCF). This information is crucial in determining your shipment’s freight class and shipping costs.
FreightCenter’s Freight Density Calculator automates this equation to provide accurate and reliable results in seconds. The calculator is easy to use, and you can use it for free on their website.

Q. What is Freight Density?
Freight density is the measure of how much space your shipment occupies in relation to its weight. It is calculated by dividing the total weight of the shipment by its volume (cubic feet). This figure is crucial for determining the freight class and subsequently, the shipping cost.
Q. Why is Freight Density Important?
Freight density is a key factor in determining your shipment’s freight class, which directly impacts your shipping costs. Lower density items take up more space in a truck but weigh less, often resulting in higher shipping costs per unit of weight. Understanding and accurately calculating your shipment’s density can help you avoid unnecessary expenses and ensure you’re billed correctly.
Q. How Do I Calculate Freight Density?
To calculate freight density:
- Measure the length, width, and height of your shipment in inches.
- Multiply these dimensions to find the cubic inches of your shipment.
- Convert cubic inches to cubic feet by dividing the total cubic inches by 1,728 (since 1 cubic foot equals 1,728 cubic inches).
- Divide the total weight of the shipment (in pounds) by the cubic feet to get the density in pounds per cubic foot (PCF).
For example:
- Shipment Dimensions: 48″ x 40″ x 24″
- Total Weight: 800 lbs
- Cubic Inches: 48 x 40 x 24 = 46,080 cubic inches
- Cubic Feet: 46,080 / 1,728 = 26.67 cubic feet
- Density: 800 lbs / 26.67 cubic feet = 30 PCF
Q. What is Freight Class and How is it Related to Density?
Freight class is a standardized classification system used by carriers to determine shipping costs. It is based on several factors including density, stowability, handling, and liability. The freight density is often the primary factor; as density increases, the freight class typically decreases, resulting in lower shipping costs.
Q. What Are Common Freight Classes Based on Density?
The National Motor Freight Traffic Association (NMFTA) uses density to categorize freight into classes ranging from Class 50 to Class 500. Here’s a general breakdown:
- Class 50: Density of 50 PCF or higher (e.g., heavy, dense freight like steel)
- Class 55-85: Density between 35-50 PCF (e.g., machinery, automotive parts)
- Class 92.5-175: Density between 10-35 PCF (e.g., furniture, appliances)
- Class 200-500: Density less than 10 PCF (e.g., fragile items, large bulky items like ping pong tables)
Q. Can Incorrect Density Lead to Reclassification?
Yes, if the carrier determines that the freight density was inaccurately reported, your shipment could be reclassified to a higher freight class, resulting in additional fees. This is why it’s crucial to use a reliable freight density calculator and ensure your measurements and weight are accurate.
Q. What Happens if My Freight is Reclassified?
If your shipment is reclassified, the carrier will adjust the freight class based on their assessment of the density, which can increase your shipping costs. Additionally, you may be charged for reclassification, and the billing process could be delayed.
Q. How Can I Avoid Freight Reclassification?
To avoid freight reclassification:
- Always use precise measurements and weigh your shipment accurately.
- Double-check your calculations with a Freight Density Calculator.
- Make sure your packaging is optimized to reduce unnecessary volume.
- Provide clear and accurate documentation to the carrier.
Q. What Types of Freight Require Density Calculations?
Density calculations are required for most types of freight, especially for Less Than Truckload (LTL) shipments. Full Truckload (FTL) shipments may also require density calculations depending on the nature of the cargo and the carrier’s requirements.
Q. Is Freight Density the Only Factor in Determining Freight Class?
No, while density is a significant factor, other elements such as stowability (how easily the freight can be stored), handling requirements, and liability (the value and risk of damage) also contribute to determining the final freight class.
