CBM Calculator for Freight
CBM Calculator for Freight brings cargo length, width, height and quantity into the same LogicCalc workspace as route, timing and transport economics. Review total CBM and trailer volume utilisation before quoting or dispatching.

How it works
How it works
Calculate freight volume from the dimensions and quantity of each cargo line, then read the total in cubic metres. CBM describes occupied volume; it does not by itself tell you how much trailer floor length or payload the load needs.
Calculate volume line by line
LogicCalc multiplies length × width × height × quantity for each line and adds the results into one total CBM figure.
Read CBM with loading constraints
Use the volume result alongside weight, floor space and loading information. Two loads with the same CBM can still require very different trailer layouts.
Typical use cases
What you can use CBM Calculator for Freight for
Use CBM when volume matters to quoting or capacity planning, but keep it separate from LDM, pallet positions and payload.
Bulky freight quoting
Estimate the cubic volume of crates, boxes or other bulky freight before preparing a transport price or checking trailer volume.
Trailer capacity checks
Compare total cargo volume with the selected trailer profile as an early capacity check before detailed loading arrangement.
Mixed cargo planning
Add several cargo lines with different dimensions and quantities to see their combined volume instead of calculating each item separately.
Practical example
Practical example
Ten crates measuring 1.2 × 0.8 × 1.5 m each equal 14.4 m³. Entering dimensions for every cargo line lets LogicCalc total the volume alongside weight and floor-space use.
Frequently asked questions
CBM Calculator for Freight FAQ
How is CBM calculated?
For rectangular cargo, multiply length × width × height in metres and then by quantity. The cubic metres from all cargo lines are added together.
Is CBM the same as LDM?
No. CBM measures three-dimensional volume, while LDM represents trailer floor length. Stacking, width and cargo shape can make the relationship very different.
Does a low CBM guarantee that the cargo fits?
No. Weight, floor dimensions, stackability and the shape of individual pieces still matter. CBM is one capacity indicator, not a complete loading plan.
Can I combine different cargo sizes?
Yes. Enter each size as a separate cargo line with its own quantity; the calculator totals their cubic volume.
What to verify before using the result
Treat CBM as a volume calculation, not as proof that a particular trailer can physically or legally carry the load.
- Use the real outer dimensions of packed cargo; packaging, frames or pallets can increase occupied volume.
- Check floor space and stackability separately because equal cubic volume can be arranged very differently inside a trailer.
- Check payload and loading limits separately; cubic metres do not describe cargo weight or axle distribution.
