A **freight class calculator** is an **essential tool** in the shipping industry that helps determine the **appropriate freight class** for a shipment based on its characteristics.

Freight class is a **standardized method** used to categorize freight shipments, primarily influencing **shipping costs** and **handling requirements**. The **FedEx freight class calculator** takes into account factors such as **density**, **stowability**, **handling**, and **liability** to assign a specific class to the cargo.

Consider a shipment of books weighing **500 pounds** and occupying **10 cubic feet**. Using a **ltl freight class calculator**, you’d input these values to determine the **density** (50 pounds per cubic foot). The calculator would then assign a freight class based on this density, likely **Class 70** in this case.

## Freight Class Calculator

Item Description | Weight (lbs) | Length (in) | Width (in) | Height (in) | Volume (cu ft) | Density (lbs/cu ft) | Freight Class |
---|---|---|---|---|---|---|---|

Canned goods | 1500 | 48 | 40 | 36 | 40 | 37.5 | 70 |

Electronics | 800 | 60 | 48 | 48 | 80 | 10 | 100 |

Steel pipes | 2000 | 96 | 48 | 24 | 64 | 31.25 | 70 |

Mattresses | 300 | 80 | 60 | 40 | 111.11 | 2.7 | 150 |

Machine parts | 1200 | 48 | 36 | 24 | 24 | 50 | 60 |

## Freight Class Formula

The **Freight Class Formula** formula is:

**Density = Weight / Volume**

Where:

**Weight**is measured in pounds**Volume**is measured in cubic feet

For instance, if you have a shipment

weighing 1000 poundsthat occupies50 cubic feet, the density calculation would be:

**1000 pounds / 50 cubic feet = 20 pounds per cubic foot**

## How do you determine freight class?

While density is often the starting point, the process considers multiple factors:

**Density**: Calculate the pounds per cubic foot as described in the formula above.**Stowability**: Assess how easily the item can be stored with other freight. Unusual shapes or sizes may increase the class.**Handling**: Consider whether the item requires special handling equipment or care.**Liability**: Evaluate the item’s susceptibility to damage, theft, or perishability.

A **pallet of bricks** might have a high density (over 50 pounds per cubic foot) and be relatively easy to handle and stow, resulting in a low freight class like **Class 50**.

On the other hand, a shipment of delicate glassware, despite potentially having a similar density, would likely be assigned a higher class due to its **fragility** and higher liability.

Another example could be a shipment of mattresses. While they might have a low density, their **bulky nature** affects stowability, potentially resulting in a higher freight class than their density alone would suggest.

## What is freight class 70?

**Freight class 70** is a specific classification in the **National Motor Freight Classification (NMFC)** system. It typically applies to shipments with a density between **15 and 22.4 pounds per cubic foot**. Common items in this class include:

**Car accessories**and**car parts****Food items**(bottled or canned)**Hardware****Automotive engines**

For instance, a pallet of canned goods weighing 1500 pounds and occupying 75 cubic feet would have a density of 20 pounds per cubic foot, falling into the **Class 70** range.

This class represents items that are relatively dense but not as heavy as lower classes like **50** or **60**. Class 70 items generally have moderate handling requirements and liability risks.

## How do you calculate freight density?

Calculating **freight density** process requires knowing the total weight and dimensions of your shipment. Follow these steps:

- Measure the length, width, and height of your shipment in inches.
- Multiply these three measurements to get the total cubic inches.
- Divide the total cubic inches by
**1,728**to convert to cubic feet. - Weigh your shipment in pounds.
- Divide the weight by the cubic feet to get the density in pounds per cubic foot.

let’s calculate the density of a shipment measuring **48″ x 40″ x 36″** and weighing 900 pounds:

- Volume in cubic inches: 48 x 40 x 36 = 69,120 cubic inches
- Convert to cubic feet: 69,120 / 1,728 = 40 cubic feet
- Density calculation: 900 pounds / 40 cubic feet = 22.5 pounds per cubic foot

This density would place the shipment just at the border between **Class 70** and **Class 65**.

## What freight class is 100?

**Freight class 100** is often considered a **baseline** in freight classification. It typically applies to shipments with a density between **9 and 10.4 pounds per cubic foot**. This class includes a wide variety of goods, such as:

**Car parts**and**accessories****Boat parts**and**accessories****Caskets****Cast iron stoves****Gaming machines**

Class 100 represents items that are less dense than lower classes but still have moderate handling requirements. For example, a shipment of car doors weighing 500 pounds and occupying 50 cubic feet would have a density of 10 pounds per cubic foot, falling into **Class 100**.
