Chargeable weight

For a transport company to sell their free space more efficiently, the industry developed a concept known as Chargeable Weight...

Why do carriers not use gross weight or volume when calculating freight costs?

Some goods are heavy but take up very limited space, others are really light but take up alot of space in a trailer.

How do we calculate Chargeable Weight?

We use these calculations:

  1. Gross weight

  2. Loading meter (Ldm weight)

  3. Volumetric weight

Chargeable weight = the largest weight from the 3 calculations above

Let us assume that we want to ship a consignment that consists of 10 pallets with the following measurements: 

  • Dimensions of each pallet [mm]: 1200 x 1000 x 1800

  • Weight of each package [kgs]: 960 gross weight


Step 1:  Add the weight factors 


Each carrier will have a:

  • Volumetric [cbm] factor. For example, 1 m3 = 333 kgs

  • Loading meter [Ldm] factor. For example, 1 pallet space = 1250 kgs

Step 2:  Calculating the gross weight of the cargo


The gross weight of our cargo is 9600 kgs.

Step 3 :  Calculating the Ldm of the consignment

We will multiply the length and width of the consignment and then divide by the width of the trailer. We are using a default of 2.4m. [= 0.5 ldm]

Now multiply that figure by the number of pallets. [= 5 ldm]

Example of the carriers Loading meter factor = 1250 kgs / ldm

LDM weight = Total Ldm of the consignment x road shipment Ldm weight factor

Ldm Weight= 5 Ldm x 1250 kgs/ Ldm = 6250 kgs


Step 4 :  Calculating the volumetric weight of the cargo


We will multiply the volume of the consignment with the volumetric weight factor of the carrier to get the volumetric weight.

Example of the carriers volumetric weight factor = 333 kgs / cbm

Volumetric Weight = Total volume of the consignment x road shipment volumetric weight factor

Volumetric Weight= 21,6 cbm x 333 kgs/ cbm = 7192,8 kgs


Step 5 : Calculating the chargeable weight of the cargo: 


We now compare:


  • the gross weight 

  • the Loading meter weight 

  • the volumetric weight


of the consignment and select the biggest amount. This will be your chargeable weight for the given shipment. 

Stacking of a consignment

This is based on the information received through the interfaced orders or by using the stackable function in Create Order.

Event will then divide the number of HU's by half to show as stacked.

note: Users can select the calculations that they want to use. For example they may only calculate Gross weight and Volumetric weight.

Implementing Chargeable Weight

How to start calculating

This guide will step through getting started with activating Chargeable Weight

Now it's active, how do i use it?

Once activated for a carrier, you don't need to worry about anything. Event will tell you if you need to know.

  • Selecting a carrier activated with the Chargeable Weight calculation, Event will calculate the cost for you. Don't worry.

  • Simply select stacked if the shipment is stackable and you will only see this if the carrier charges by Chargeable Weight

  • If changing carrier Event will show you the carriers charging mechanism just so you are aware we know and the calculation includes it.

  • Try selecting and deselecting 'stackable' just to see the calculation change!
