Getting Your Head Around Chargeable Weights [With Excel Calculator]
October 28, 2022 Air Freight, Sea Freight
If you are reading this article you may be wondering what volumetric ratios (or chargeable weights) are and why, as an importer or exporter, they should matter to you. It is not uncommon that as a forwarder we are asked this question.
What is Volumetric Ratio in Freight?
Essentially, volumetric ratios (or chargeable weights) are used to ensure the weight or size of your cargo are considered in equal measure when shipping.
For example, imagine you have a piece of steel you would like to send LCL (Less Container Load) via sea freight. Now, imagine the steel is small in size (0.5cbm) but weighs over 2000kgs. LCL freight is charged in cubic meters. However, on this occasion, your goods are not taking up much space in the container but are using a lot of the container’s weight capacity. This is where the volumetric ratio comes in.
This is also the case for airfreight. Airfreight is charged in KGs. Consider you are shipping something light like toilet rolls. The toilet rolls only weigh 100kgs however, they take up 5 cubic meters worth of space. The airline will now charge you a volumetric weight to cover the space taken up on the aircraft.
Understanding chargeable weights is essential when calculating the cost of your freight.

How to Calculate Volumetric Ratio For Air and Sea Freight
To effectively calculate your volumetric ratios, you can use the formula below.
The key rule to remember is: You will always be charged by whatever is higher, your chargeable weight or your cubic meters or KGs.
Volume ratio: 1m3 = 167 kgs
Formula: m3 x 167 = chargeable weight
*If actual weight is higher you will be charged on actual weight.
Volume ratio: 1 m3 = 1000 kgs
Formula: m3 x 1000 = chargeable weight
*If actual cube is higher than chargeable weight you will be charged on actual cube.
Let’s take our example above to calculate chargeable weight and return to our toilet rolls. Remember our toilet rolls weigh 100kgs but in volume they are 5 cubic meters.
For an airfreight shipment 1 cubic meter is the equivalent of 167kgs.
5 x 167kgs = 835
Your chargeable weight is 835kgs for this shipment which is higher than 100kgs. You will, therefore, be charged for sending 835kgs via airfreight.
