Check a container load from both the space and payload perspectives. Enter internal container volume, loaded cargo volume, maximum payload, and cargo weight. The calculator reports cube utilization, weight utilization, and the more restrictive overall utilization, plus remaining volume and payload. This dual view helps avoid calling a dense load “underused” simply because some cubic space remains.
Cube utilization = cargo volume ÷ internal volume × 100%
Weight utilization = cargo weight ÷ maximum payload × 100%
Overall utilization = higher of the two
Overall utilization uses the tighter constraint. It does not mean that every remaining cubic meter can accept cargo, because weight or placement may already prevent additions.
Values above 100% flag an entered limit exceedance; they are not clipped so the size of the overage stays visible.
Loading 54 m³ and 18,000 kg into a 67.5 m³ container with a 26,500 kg payload gives 80.0% cube utilization and 67.9% weight utilization. Overall utilization is 80.0%.
The higher ratio identifies the constraint closer to its limit and therefore the one restricting additional cargo.
Yes, if entered cargo volume exceeds internal volume; the overage signals inconsistent or overloaded input.
No. Shape, orientation, door clearance, and weight can make the remaining cube unusable.
Include every item counted against the container payload under your loading rules.
Not necessarily. A light load can legitimately be space-bound, so interpret both ratios together.
| Variable | Meaning | Unit |
|---|---|---|
| Cube utilization | Loaded cube ÷ internal cube | percent |
| Weight utilization | Cargo weight ÷ payload | percent |
| Overall utilization | Higher constraint ratio | percent |
| Remaining capacity | Non-negative unused cube and payload | m³ / kg |
