Understanding chargeable weight is essential for businesses and individuals shipping goods via domestic air cargo in Australia. Airlines and freight providers calculate costs not only based on actual weight but also considering volumetric weight, distance, and service type. Accurately calculating chargeable weight ensures cost-effective shipping and prevents unexpected charges.

What is Chargeable Weight?
Chargeable weight is the higher value between the actual weight and volumetric (dimensional) weight of a shipment. Airlines and freight providers use this measurement to calculate shipping fees, ensuring efficient use of cargo space and fair pricing. This method applies to both standard and express domestic air cargo services.
Actual Weight vs Volumetric Weight
Actual Weight: The physical weight of your parcel measured in kilograms (kg).
Volumetric Weight: Calculated based on the dimensions of the shipment using the formula:
Volumetric Weight (kg) = (Length × Width × Height in cm) / 6000
Airlines charge the higher of the two to account for large but lightweight items that occupy significant space in the aircraft. This practice ensures efficient cargo loading and safety compliance in accordance with CASA and IATA standards.
Factors That Affect Air Cargo Charges
- Distance: Longer domestic routes, such as Sydney to Perth, typically cost more due to fuel and operational considerations.
- Delivery Speed: Express and same-day services incur higher charges compared to standard shipments.
- Special Handling: Perishable goods, pharmaceuticals, or dangerous goods may require temperature-controlled or secure handling.
- Insurance: Optional coverage for high-value or sensitive cargo adds to the overall cost.
Example: Calculating Chargeable Weight
Suppose you are shipping a parcel with an actual weight of 50kg, but its dimensions are 100cm × 80cm × 60cm. Using the volumetric formula:
Volumetric Weight = (100 × 80 × 60) / 6000 = 80 kg
Since 80kg (volumetric) is higher than the actual weight of 50kg, the carrier charges based on 80kg. Understanding this calculation helps you plan packaging and manage costs effectively.
