How to Accurately Determine Your Product's Weight and Understand Shipping Charges in Dropshipping( Weight Calculator Included)

If you're involved in dropshipping, you might think your package's real weight is just the weight shown on a scale—but that's not entirely true.

Many dropshippers are unaware that shipping costs are often determined not only by the actual weight but also by the volumetric weight (also known as dimensional weight). This is a critical factor in logistics, especially for packages that take up more space relative to their weight.

What Is Volumetric Weight?

Volumetric weight is a measurement used in logistics to calculate shipping costs based on the amount of space a package occupies, rather than its actual weight. This method is used when a package's size is more significant than its physical weight. For example, a lightweight but bulky package may cost more to ship due to the space it occupies in the cargo.

Why Does Volumetric Weight Matter?

Shippers use the volumetric weight ratio to determine whether to charge you based on the actual weight or the volumetric weight of your package. The rule is simple:

• If the volumetric weight is greater than the actual weight, the shipping cost will be calculated based on the volumetric weight.

• If the volumetric weight is equal to or less than the actual weight, you'll be charged based on the actual weight (this is sometimes referred to as "bubble-free billing").

How to Calculate Volumetric Weight?

Volumetric Weight (kg)=Length (cm) × Width (cm) × Height (cm)​/8,000

Use the Calculator Below to Simplify Your Calculations

To make it easier for you, feel free to use the calculator below to determine your package's volumetric weight and compare it to the actual weight. This will help you anticipate shipping costs and avoid surprises in your dropshipping business.

For example:

If your package dimensions are 40 cm × 30 cm × 20 cm, the volumetric weight would be: 40×30×20/8,000=3 kg

Now compare this to the actual weight of the package. If the actual weight is 2 kg, the shipping cost will be based on the volumetric weight (3 kg) since it’s greater. However, if the actual weight is 4 kg, the shipping cost will be based on the actual weight.

We hope this blog helps you, fellow dropshippers! By understanding how shipping charges are calculated, you can plan better, optimize your packaging, and keep your costs under control. Happy dropshipping!
