MARITIME – CARGO, LOADING & TABILITY (COMMERCIAL) CALCULATOR
Stowage Factor
A precise tool.
What is the Stowage Factor & How does it work?
The stowage factor is a key parameter in bulk cargo handling, expressing how many cubic metres of space a tonne of cargo occupies in a ship’s hold.
A low stowage factor indicates a dense commodity such as iron ore, while a high factor is typical for light, voluminous goods like coal or grain.
Accurate stowage‑factor calculations enable planners to optimise loading sequences, maintain stability, and avoid costly under‑utilisation of cargo space.
\text{SF}=\frac{V}{W}
SF = Stowage Factor (m³/tonne)

Frequently Asked Questions
What is stowage factor in maritime?
Stowage factor is the volume of space occupied by one tonne of cargo, measured in cubic meters per tonne (m³/tonne).
How do I calculate stowage factor?
Divide the total volume of the cargo (in cubic meters) by its weight (in tonnes) to get the stowage factor.
Why is stowage factor important in shipping?
It helps optimize cargo loading, maintain ship stability, and prevent underutilization of cargo space.
What does a low stowage factor indicate?
A low stowage factor indicates dense commodities like iron ore, which occupy less volume per tonne.
Can you give an example of high stowage factor cargo?
Coal or grain have a high stowage factor as they are light and take up more space per tonne.
How does stowage factor affect ship stability?
Proper stowage ensures even distribution of weight, which is crucial for maintaining the ship's stability during transit.
What are some common mistakes in calculating stowage factor?
Common mistakes include using incorrect volume or weight measurements, not accounting for packaging, and ignoring variations in cargo density.
