How to Use This Calculator

Select the container type: 20ft standard, 40ft standard, or 40ft high cube.
Enter the tare weight and maximum gross weight in kg from the container's CSC plate.
Input the cargo weight in kg and cargo density in t/m³.
Review maximum payload, actual gross weight, and weight margin remaining.
Ensure weight utilization is within limits before booking — overloaded containers attract fines.

How the result changes with Max Gross Weight

Container Type: Standard ISO container size.
Tare Weight: Empty container weight (shown on door plate). 20ft ~2,300 kg, 40ft ~3,800 kg.
Max Gross Weight: Maximum gross weight per ISO rating (usually 30,480 kg).
Cargo Weight: Total weight of cargo to be loaded.
Cargo Density: Average cargo density. Electronics ~0.3, machinery ~1.5, steel ~5.
