Importers routing through Felixstowe — the UK's busiest container port, handling roughly half of Britain's deep-sea boxes — face the same two-clock reality as every major gateway: carrier demurrage on the box and terminal storage on the ground slot. This tool models the demurrage layer with Felixstowe-realistic defaults (5 free days, escalating to £230/day).
About Port of Felixstowe Demurrage Calculator
Past industrial actions and haulage shortages have produced quayside backlogs — and a body of precedent for free-time extensions during disruption. That local context matters when disputing: charges driven by the port's own dynamics rather than your idleness are the recoverable kind, and knowing the pattern is half the evidence. Work the math before the deadline, not after: enter days since discharge, your contracted free time and the tariff tiers. The per-tier breakdown mirrors how the carrier's billing system itemises the invoice, so any mismatch you find is a concrete dispute line — not a feeling that the bill is high.

Frequently asked questions
How much demurrage would a container at Felixstowe owe after 12 days?+
Under the preloaded example (5 free days, then £95 for 3d, £150 for 4d, £230 after): 7 chargeable days = 3 × £95 + 4 × £150 = £885 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 Felixstowe?+
Carrier tariffs key the clock to discharge or availability, and at Felixstowe 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.
What happens to free time during Felixstowe disruptions?+
During strike or backlog periods carriers have typically extended free time or waived demurrage for affected windows — but rarely automatically. Keep the port's customer advisories from the disruption dates; quoting the advisory with your container's timeline converts a discretionary waiver into a near-formality.
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.
