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 Miami starts a countdown. The port is the principal US gateway for Caribbean and Latin American container trades, with heavy reefer (perishables) volume, 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 Miami Demurrage Calculator
Local knowledge: Perishable flows mean reefer plug-in and monitoring fees stack onto demurrage more often here than at most US ports. Patterns like this are why a generic demurrage estimate misleads — defaults here are tuned for Miami, 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 9-day dwell under the example tariff costs $945 per container — visible here before it's payable there.

Frequently asked questions
How much demurrage would a container at Miami owe after 9 days?+
Under the preloaded example (4 free days, then $155 for 3d, $240 for 3d, $335 after): 5 chargeable days = 3 × $155 + 2 × $240 = $945 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 Miami?+
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.
What extra fees hit reefers at PortMiami?+
Beyond demurrage: plug-in/electricity, temperature monitoring rounds and shorter reefer free time (often 2–3 days). A delayed mango or fish box accrues three meters at once. Model the power layer with our reefer plug-in calculator and keep this one for the demurrage layer — disputing one doesn't pause the other.
Demurrage vs detention — which one is this?+
This models demurrage: the box inside the Miami 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.
