Billable Weight

A Comprehensive Guide to Billable Weight

Understanding the concept of billable weight is crucial for businesses and individuals alike. As a determinant of shipping costs, billable weight takes into account both the actual weight and the dimensional weight of a package.

In this comprehensive guide, we will explore  billable weight, its calculation, and explore effective strategies to optimize and reduce shipping costs.

What is Billable Weight?

Billable weight is a pivotal factor in the shipping industry, serving as the basis for calculating shipping costs. Unlike the traditional approach, where shipping costs were determined solely by the actual weight of a package, billable weight introduces a more nuanced calculation.

It considers both the actual weight and the dimensional weight, utilizing the higher of the two as the billable weight for determining shipping rates.

The Evolution of Billable Weight

The history of billable weight reflects the industry’s response to the challenges posed by lightweight yet voluminous packages. Prior to 2015, carriers primarily relied on the actual weight and shipping distance for cost calculations. However, this method proved inefficient for volumetrically large but lightweight shipments, leading to the adoption of billable weight. This evolution aimed to incentivize shippers to optimize their packaging for size and weight efficiency.

Calculating Billable Weight

The Dimensional Weight Calculation Process

Dimensional weight is a key component of billable weight, calculated by measuring the cubic size of a package and dividing it by a carrier-specific DIM divisor. The process involves:

  1. Measuring the length, width, and height of a package using the longest points on each side.
  2. Multiplying these dimensions to obtain the cubic size of the package.
  3. Dividing the cubic size by the carrier’s DIM divisor to determine the dimensional weight.

Different carriers may have distinct DIM divisors, such as FedEx’s 139, UPS’s 139 for daily packages, and 166 for retail packages, and USPS’s 166.

The Actual Weight Calculation Process

In contrast, the actual weight is determined by placing the package on a scale and rounding the measured weight to the next whole pound. This straightforward method accounts for the tangible mass of the shipment.

Billable Weight Comparison

Understanding the distinctions between dimensional weight, actual weight, and billable weight is essential in navigating the complex realm of shipping costs.

1. Dimensional Weight:

Dimensional weight is a calculated value that considers the volume or space a package occupies during transportation. It is determined by measuring the length, width, and height of a package and dividing the result by a specific dimensional factor or divisor. 

The goal is to account for larger, lightweight packages that occupy significant space in shipping vehicles. Different carriers may use different dimensional divisors.

2. Actual Weight:

Actual weight is the straightforward measurement of the physical mass of a package. It is determined by placing the package on a scale, and the recorded weight is typically rounded up to the next whole pound.

Actual weight provides a tangible measure of the load a shipping carrier must transport.

3. Billable Weight:

Billable weight is the pivotal factor used in calculating shipping costs. It is derived by comparing the dimensional weight and the actual weight of a package and selecting the higher of the two values.

This higher value becomes the billable weight, upon which the shipping rate is based. Billable weight accounts for the economic reality that carriers need to consider both the physical weight and the space a package occupies when determining shipping costs.

Billing and Shipping Cost Determination

The shipping cost is derived from the billable weight, emphasizing the significance of accurate measurements and packaging optimization. As billable weight serves as the foundation for cost calculations, businesses can strategically minimize expenses through effective packaging practices.

Strategies for Optimizing Billable Weight

Reviewing Packaging Options

One of the most impactful ways to optimize billable weight is to review and reconsider packaging options. Often, businesses make the mistake of using standard boxes for all shipments, leading to higher shipping costs. By selecting appropriate packaging for each item, considering its dimensions and weight, businesses can reduce billable weight and enhance cost-effectiveness.

Advanced tools offered by some logistics providers, like Box Selection algorithms and Cubiscan machines, consider actual product dimensions and packaging preferences. These tools recommend the optimal box size for any order combination, ensuring consistent pricing and reducing billable weight.

Switching to Poly Mailers

Poly mailers offer a lightweight and flexible alternative to traditional boxes. Particularly advantageous for items like apparel, poly mailers reduce dimensional weight and minimize shipping costs. Additionally, some poly mailers come with built-in bubble wrap padding, providing protection without the need for extra dunnage.

Poly mailers are versatile, sturdy, and cost-effective. Their flexibility allows them to conform to the shape of the contents, eliminating unnecessary empty space and reducing billable weight.

Embracing Ships in Own Container (SIOC) Packaging

SIOC is a packaging strategy where products are shipped in their original packaging without the need for additional overboxing. This approach not only reduces redundant packaging but also has the potential to save money by minimizing billable weight.

SIOC eliminates the need for an extra layer of packaging, as products can be shipped directly in their original boxes. This streamlines the shipping process and contributes to cost efficiency.

Case Studies and Real-world Examples

Stuffed Teddy Bear Case Study

Consider a large stuffed teddy bear as an example. While lightweight, its larger dimensions contribute to a higher dimensional weight compared to its actual weight. The DIM divisor plays a crucial role in calculating the teddy bear’s billable weight.

  1. Dimensional Weight: Length×Width×Height/DIM Divisor
  2. Actual Weight: Weighing the teddy bear on a scale.
  3. Billable Weight: The higher of the dimensional weight and actual weight.

Dumbbell Case Study

Contrastingly, a heavy item like a dumbbell with smaller dimensions is likely to have an actual weight higher than its dimensional weight. In this case, the actual weight becomes the billable weight.

  1. Dimensional Weight: Length×Width×Height/DIM Divisor 
  2. Actual Weight: Weighing the dumbbell on a scale.
  3. Billable Weight: The higher of the dimensional weight and actual weight.

Final Thoughts

Understanding billable weight is essential for businesses seeking to optimize their shipping costs. As the logistics industry continues to evolve, staying informed about shipping cost determinants will be crucial for maintaining a competitive edge and ensuring cost-effective shipping practices.

As technology advances and sustainability becomes a priority, the future of billable weight may see further innovations. The integration of artificial intelligence and machine learning algorithms into logistics processes could refine packaging recommendations, minimizing billable weight and environmental impact.
