Demurrage Exposure at 69% share of containers at risk of dwelling: a worked example

Push share of containers at risk of dwelling up to 69% and the picture changes. This example computes every intermediate figure at that operating point. Use it when containers may miss free time because of customs holds, appointment delays, warehouse congestion, or paperwork issues.

The inputs for this scenario

  • Chargeable demurrage days beyond free time: 5 days (unchanged)
  • Carrier demurrage rate per container: 175 $ / day (unchanged)
  • Share of containers at risk of dwelling: 69 % (raised for this scenario; the documented default is 60)
  • Fixed release and drayage cost: 300 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable demurrage exposure = chargeable demurrage days × demurrage rate × at-risk container share) to the inputs above produces each figure below.
  • At this operating point the engine returns 904 $ for total demurrage exposure, the number this scenario is built around.
  • At this operating point the engine returns 181 $ / unit for demurrage cost per day.
  • At this operating point the engine returns 604 $ for variable demurrage exposure.
  • At this operating point the engine returns 300 $ for fixed charges.

How this compares with the baseline

  • Against the tool's baseline example, where share of containers at risk of dwelling sits at 60% and the headline result is 825 $, this scenario comes in 9.55% above the baseline at 904 $.
  • It computes the total demurrage dollar risk by combining chargeable days times daily rate times the at-risk container share, then adding fixed release and drayage costs. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
