Understanding Billable Weight

and strategies to reduce shipping costs

Shipping costs can significantly impact your bottom line, especially in the eCommerce industry. One key factor that affects shipping rates is the concept of billable weight. Here’s a comprehensive guide on what billable weight is and practical strategies to reduce your shipping expenses.


What is a billable weight?


Billable weight is a term used by shipping companies to determine the cost of shipping a package. It can be either the actual weight of the package or its dimensional weight, whichever is greater.

  • Actual Weight: This is the total weight of the package and its contents, measured on a scale.
  • Dimensional Weight (DIM): This is calculated based on the dimensions of the package. It is determined by multiplying the length, width, and height of the package and then dividing by a standard DIM divisor set by the carrier.

Shipping companies use the greater of these two weights to calculate the shipping cost, ensuring they account for both the size and weight of the package​.


Strategies to Reduce Shipping Costs

1. Optimize Packaging:

  • Use the right size boxes: Ensure that the box you use is just big enough to fit the items securely without excess space. This reduces the dimensional weight.
  • Poly mailers: For non-fragile items, consider using poly mailers instead of boxes to minimize dimensional weight​.
  • Custom packaging: Invest in custom-sized packaging that fits your products perfectly to avoid unnecessary dimensional weight​​.

2. Leverage Third-Party Logistics Providers (3PL):

  • Expertise and resources: 3PLs can offer optimized packaging solutions and have better-negotiated rates with carriers due to their shipping volumes.
  • Distributed warehousing: By storing inventory in multiple warehouses, you can reduce the distance packages need to travel, thereby lowering shipping costs​​.

3. Utilize shipping calculators:

Use shipping calculators from major carriers like FedEx, UPS, and USPS to compare rates and choose the most cost-effective shipping option for each package. This helps in making informed decisions and avoiding unnecessary costs​​. Here are a few useful shipping calculators offered by major shipping carriers:

4. Negotiate with carriers:

If you have significant shipping volume, negotiate for better rates with your carriers. Many carriers offer discounts based on shipping volumes or long-term commitments​.

5. Flat rate shipping options:

Utilize flat-rate shipping options offered by carriers like USPS for heavy but small-sized packages. This can often be more cost-effective than weight-based rates​​.

6. Reduce returns:

Implement policies to minimize returns, such as offering accurate product descriptions and sizing guides. Reducing returns helps in cutting down the associated return shipping costs​​.

By understanding the concept of billable weight and applying these strategies, you can effectively manage and reduce your shipping costs, thereby enhancing your overall profitability.
