Freight utilization expresses used capacity as a proportion of a defined available capacity. Weight, floor space and cube are different measures, so they can produce different percentages for the same load. None alone proves that more freight can safely be added.
This worksheet compares planning inputs. It does not establish legal payload, certify loading or replace a vehicle-specific capacity and securement assessment.
Define each denominator
| Measure | Calculation | Important limitation |
|---|---|---|
| Weight utilization | Freight weight ÷ defined available payload | Total and distribution constraints still apply |
| Floor utilization | Occupied usable floor area ÷ defined usable floor area | Irregular shapes and handling access matter |
| Cube utilization | Packed occupied volume ÷ defined usable volume | Space may not be stackable or accessible |
Do not use a vehicle’s overall exterior dimensions as though they were its usable cargo space. Obtain the appropriate inputs for the actual equipment and operating arrangement.

The calculator returns three percentages from user-entered used and available values. It is a diagnostic worksheet, not permission to load to a displayed limit.
A hypothetical load with three different results
Assume 4,000 kg of freight against a defined 8,000 kg available payload: 50% weight utilization. If it occupies 18 m² of a 20 m² usable floor, floor utilization is 90%. If its packed envelope occupies 24 m³ of a 50 m³ reference volume, cube utilization is 48%.
This load is not simply “half full.” Its floor is substantially occupied under the example assumptions. If the freight cannot be stacked, unused overhead cube may not be usable for another shipment.
Read the binding constraint
A long unit can constrain floor layout; a dense item can constrain weight; a tall unit can constrain clearance. Loading order, handling access and compatibility can introduce further restrictions not captured by any one percentage.
Use the linear-foot calculator and packed-dimension guide to improve the inputs. Do not convert a drawing into a load approval.
Aggregate consistently
When comparing several movements, divide total used capacity by total comparable available capacity for the chosen measure. A simple average of individual percentages can mislead when their denominators differ.
For example, 2,000 kg used out of 4,000 kg and 8,000 kg used out of 8,000 kg produce individual percentages of 50% and 100%. The combined weight utilization is 10,000 ÷ 12,000 = 83.33%, not 75%. These are fictional capacity inputs.
Use the result to ask a better equipment question
Describe the actual constraint to dispatch: floor space, height, weight, non-stackability or access. That is more useful than saying a load “should fit because it is only half the cube.”
WTM can review freight equipment against your packed load and receiving arrangement. Send the underlying unit dimensions and weights with the utilization worksheet so the team can assess the real shipment rather than an isolated percentage.
