Demurrage calculator
Work out what a container held at the port costs, from your own carrier’s free time and daily rates. Nothing is assumed: the figures are the ones you enter.
Shipment
From your booking or the carrier’s tariff for the port.
From discharge until the container is released (or the day you expect it to be).
Currency
Estimated charges
US$0
Enter the daily rate from your carrier’s tariff to see the total.
An estimate only: carriers count days, round and apply rates differently. Check the invoice terms with your carrier.
Where to find these numbers
- The carrier’s demurrage and detention tariff for the discharge port (most carriers publish it by port).
- Your booking confirmation or contract, if free time was negotiated.
- Terminal storage is often billed separately by the port; add it as its own band if you want it in the total.
