Demurrage & Detention Calculator | Port Storage Fees

📘 How D&D charges work in Australia

• Chargeable days = max(0, actual days − free time). Tiers (e.g. days 1–5, 6–10, 11+) escalate the daily rate — the deeper you go, the more it costs.
• Demurrage is charged by the terminal/port (e.g. DP World, Patrick, VICT). Detention is charged by the shipping line (e.g. Maersk, COSCO, ONE).
• Free time at major AU ports is typically 3–7 days for import demurrage and 7–14 days for detention — always confirm in your B/L or carrier contract.
• ⚠ Reefer / hazardous / OOG (out-of-gauge) containers have shorter free time and higher daily rates — sometimes 3–5× standard.
• ⚠ Biosecurity (DAFF) holds and customs inspections do NOT pause D&D — the clock keeps running. Pre-clearance helps.
• Combined “merchant haulage” / “carrier haulage” arrangements can shift detention liability — check who’s responsible at each leg.
