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 New York / New Jersey starts a countdown. The port is the largest container gateway on the US East Coast, spread across terminals like APM Elizabeth, Maher and GCT Bayonne, 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 New York / New Jersey Demurrage Calculator
Local knowledge: Chassis availability in the harbor has historically been the binding constraint — many NY/NJ detention disputes trace back to chassis shortages rather than trucker capacity. Patterns like this are why a generic demurrage estimate misleads — defaults here are tuned for New York / New Jersey, 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 12-day dwell under the example tariff costs $1,885 per container — visible here before it's payable there.

Frequently asked questions
How much demurrage would a container at New York / New Jersey owe after 12 days?+
Under the preloaded example (4 free days, then $185 for 4d, $260 for 3d, $365 after): 8 chargeable days = 4 × $185 + 3 × $260 + 1 × $365 = $1,885 per container. Your tariff's actual brackets may differ — edit the tiers to match before relying on the figure.
When does free time start counting at New York / New Jersey?+
Per your carrier's tariff — typically from container discharge or from when it becomes available for pickup (which can lag discharge during big exchanges). The trigger definition is the first thing to check on a disputed invoice: a one-day difference in the start date often equals a whole top-tier day at the end.
Why is demurrage at NY/NJ often tied to chassis problems?+
Because picking up a box needs a chassis, and harbor chassis pools have run tight repeatedly. If you can document that no chassis was available from the pool serving your terminal before the LFD (pool notices, dray turn-away records), you have a genuine unavailability argument for the demurrage days that followed.
Demurrage vs detention — which one is this?+
This models demurrage: the box inside the New York / New Jersey terminal past free time. Detention/per diem — the clock after gate-out until empty return — runs on separate free time and rates. Use our container detention calculator for that leg; on a slow door move you may genuinely owe both.
