Plan Container Capacity and Cargo Mix
Example Data Table
| Item | Qty | Unit Size (m) | Unit Weight | Max Stack | Use Case |
|---|---|---|---|---|---|
| Standard Carton A | 600 | 0.60 × 0.40 × 0.35 | 18 kg | 5 | General boxed goods |
| Pallet Box B | 80 | 1.20 × 1.00 × 1.10 | 120 kg | 2 | Heavy palletized loads |
| Loose Case C | 250 | 0.50 × 0.30 × 0.28 | 9 kg | 6 | Supplementary filler cargo |
You can replace these sample values with your own carton or pallet dimensions and target quantities.
Formula Used
1) Effective container volume
Effective Volume = Internal Length × Internal Width × Internal Height × Usable Length Factor × Usable Width Factor × Usable Height Factor × Packing Efficiency − Clearance Allowance
2) Unit cargo volume
Unit Volume = Length × Width × Height
3) Height-based stacking limit
Height Stack Limit = Floor(Container Height ÷ Item Height)
4) Allowed stack layers
Allowed Layers = Minimum(Max Stack Layers, Height Stack Limit)
5) Floor footprint capacity per cargo
Floor Capacity = (Effective Floor Area ÷ Item Footprint) × Allowed Layers
6) Volume-limited capacity per cargo
Volume Capacity = Effective Volume ÷ Unit Volume
7) Weight-limited capacity per cargo
Weight Capacity = Max Payload ÷ Unit Weight
8) Loadable quantity
Loadable Quantity = Minimum(Required Quantity, Floor Capacity, Volume Capacity, Weight Capacity)
The planner uses these checks together to estimate the most restrictive loading condition. Real loading may vary because of bracing, dunnage, axle distribution, door geometry, and mixed packing patterns.

Frequently Asked Questions
1) What does this planner calculate?
It estimates how many units can fit inside a container using volume, footprint, stacking, and payload limits. It also reports utilization, remaining space, and the main constraint affecting the plan.
2) Can I plan mixed cargo loads?
Yes. This version supports three cargo lines and combines them into one result. It is useful for cartons, pallet boxes, and loose cases sharing the same container.
3) Why use packing efficiency?
Packing efficiency reduces theoretical capacity to reflect real-world voids, aisle gaps, uneven shapes, and practical loading losses. It helps produce more conservative and realistic estimates.
4) Does the tool replace a warehouse loading simulation?
No. It is a planning calculator, not a full 3D simulation engine. Actual loading can still change because of orientation, bracing, door access, handling equipment, and freight rules.
5) How is stacking handled?
The planner checks the lower value between your entered stack limit and the number of layers allowed by container height. That prevents unrealistic vertical placement assumptions.
6) What if weight fills before volume?
The result will show weight as the limiting factor. This means the container reaches payload capacity before its internal space is fully occupied.
7) Can I export the results?
Yes. The calculator includes CSV export for spreadsheet review and PDF export for quick sharing, filing, or printing during warehouse planning and dispatch meetings.
8) Should I include clearance allowance?
Yes. Clearance allowance helps reserve practical space for doors, bracing, load securement, and small planning buffers. It makes the capacity estimate less optimistic and more operationally useful.
