Calculate detention and demurrage charges by shipping line, container type and region.
Select carrier, container type and region, then click Calculate.
Demurrage is charged when a container sits at the port/terminal beyond the free period (before customs clearance). Detention is charged when a container is kept outside the terminal (e.g. at your warehouse) beyond the free period. This calculator estimates detention charges. Demurrage tariffs are set by the port authority and vary by terminal.
