​When shipping goods via airfreight, customers often expect charges based solely on the actual weight of their cargo. However, airlines use a concept called volumetric weight to account for large but lightweight shipments. Understanding this pricing method can help businesses optimize shipping costs and avoid unexpected charges.

​

What is Volumetric Weight?

 

Volumetric weight (also called dimensional weight) is a calculation used to determine the space a package occupies on an aircraft. If a shipment is bulky but light, the volumetric weight may be greater than the actual weight, and the airline will charge based on the higher value.

​

​How is Volumetric Weight Calculated?

 

The standard formula set by the International Air Transport Association (IATA) for airfreight volumetric weight is:

Step-by-Step Guide to Calculating Chargeable Weight

​​

1. Measure the package dimensions (Length, Width, and Height) in centimeters.

2. Apply the volumetric weight formula: Multiply the dimensions and divide by 6000.

3. Compare with actual weight: The chargeable weight is the greater of the actual weight and the volumetric weight.

4. Multiply by the freight rate to calculate the final shipping cost.

Why Do Airlines Use Volumetric Weight?

Aircraft have limited cargo space, and bulky items take up more room than their actual weight suggests. Charging by volumetric weight ensures fair pricing for both lightweight and heavy cargo.

​

Example Calculation

 

Let’s say you are shipping a package with the following details:

• Dimensions: 80 cm × 60 cm × 40 cm

• Actual Weight: 20 kg

​

Since the volumetric weight (32 kg) is greater than the actual weight (20 kg), the chargeable weight will be 32 kg.

​

If the freight rate is $12 per kg, the shipping cost will be:

​

The shipping cost is calculated using the chargeable weight, which is 32 kg in this case.

Shipping Cost = Chargeable Weight × Freight Rate
= 32 kg × $12/kg
= $384

​

So, the total shipping cost will be $384.

How to Reduce Airfreight Costs

• Optimize packaging: Use compact, efficient packaging to reduce the volumetric weight.

• Consider alternative transport: If the volumetric weight is high, sea freight might be a cost-effective option.

• Consult with Frigate Cargo & Logistics Services: Our team can help you choose the most efficient shipping method based on your cargo dimensions and weight.
