📦 Understanding Shipping Charges: Volumetric vs Weight-Based Shipping

Shipping costs are typically calculated in two ways:
Volumetric Weight and Actual Weight.
The final shipping cost is based on whichever is higher — so understanding both helps avoid unexpected charges.

✈️ What is Volumetric Weight?

Volumetric weight (also called dimensional weight) is based on the space a package occupies, not just how heavy it is.

This method is used when a parcel is:

• Light in weight
• Large in size (bulky)
• Takes up more space in aircraft or cargo containers

So even if your package is light, you may still be charged more because it occupies valuable cargo space.

📐 Formula:

(Length × Breadth × Height) / 5000

• Dimensions in centimeters (cm)
• Resulting volumetric weight in kilograms (kg)

🔍 Example:

A box that is 50cm × 40cm × 30cm weighs only 3kg, but its volumetric weight is:
(50 × 40 × 30) / 5000 = 12kg

Even though it weighs 3kg, you may be charged for 12kg due to its volume.

🏋️ What is Weight-Based Shipping?

Weight-based shipping uses the actual physical weight of the package measured on a scale.

This method is used when:

The size does not take up much space

The package is small and compact

The parcel is dense and heavy

🔍 Example:

If your parcel weighs 7kg, you’ll be billed exactly for 7kg, regardless of its size.

⚖️ Which Rate is Used?

Couriers compare both the volumetric weight and actual weight, then charge you based on whichever is higher.

This ensures:

• Fair use of cargo space
• Accurate billing for oversized but lightweight items
