Demurrage, detention and storage tariffs are set by each carrier, terminal and contract and change frequently. The preloaded figures are editable industry-typical examples, not quotes — always verify against the current published tariff or your service contract before paying or disputing an invoice.
Every container discharged at Oakland starts a countdown. The port is Northern California's container gateway and a critical export port for US agricultural products, and its velocity depends on boxes leaving on time — demurrage tiers are the enforcement mechanism. Model yours here: free time, tier rates, days on dock, and the calculator shows the bill the way the carrier will build it.
About Port of Oakland Demurrage Calculator
Local knowledge: Ag exporters here fight a particular battle: missed earliest-return-date windows when vessels roll, which can strand export boxes at the terminal accruing charges. Patterns like this are why a generic demurrage estimate misleads — defaults here are tuned for Oakland, and every field stays editable for your actual tariff. The cheapest demurrage is the day that never bills: track last free days, book pickup appointments early, and when charges do land, audit them against the published tariff. A 10-day dwell under the example tariff costs $1,155 per container — visible here before it's payable there.

Frequently asked questions
How much demurrage would a container at Oakland owe after 10 days?+
Under the preloaded example (4 free days, then $150 for 3d, $235 for 3d, $330 after): 6 chargeable days = 3 × $150 + 3 × $235 = $1,155 per container. Your tariff's actual brackets may differ — edit the tiers to match before relying on the figure.
What triggers the demurrage clock at Oakland?+
Carrier tariffs key the clock to discharge or availability, and at Oakland the distinction matters during heavy vessel exchanges when availability notices lag the crane. Compare the notice timestamp on your arrival notice with the invoice's day one — mismatches there are the easiest demurrage dollars to recover.
How do export rolls create charges at Oakland?+
When a vessel rolls, the export receiving window moves — a box already in-gated can sit through the gap, and one delivered for the old window may be refused or stored. Document the original booking window and the roll notice; charges driven purely by the carrier's own schedule change are among the most waivable line items at any port, Oakland's ag trade included.
Does this calculator cover detention (per diem) too?+
The math engine handles any free-time-plus-tiers structure, so yes — switch the inputs to your detention free days and per-diem tiers and it prices the after-gate-out leg identically. Just don't mix the two tariffs in one calculation; carriers bill them as separate line items with separate clocks.
