Method
Lead time = Handling + Transit + Clearance; Arrival = Ship date + Lead time (calendar or Mon–Fri days); Pipeline stock = Daily demand × Calendar days in transit
- Business days
- Monday to Friday; public holidays are not skipped
- Daily demand
- average units sold or used per calendar day
Worked example
- Lead time = 1 + 14 + 2 = 17 days.
- 2 March 2026 + 17 days = 19 March 2026, a Thursday.
- Pipeline stock = 50 × 17 = 850 units, worth 850 × 12 = 10,200.
Shipped on 2 March 2026, the goods arrive on Thursday 19 March, with 850 units (10,200) in the pipeline.
What the result means
Pipeline stock is cash tied up while goods move. Shorter or more reliable transit lets you hold less, which is one way to weigh a faster but dearer mode.
Assumptions and limits
- Business-day mode skips Saturdays and Sundays only.
- Demand is steady during the transit period.
- Public holidays, port congestion and carrier cut-off times are not modelled; add buffer days for them.
Questions
Does the ship date count as day 0?
Yes. One day of transit means arrival on the next day.
How does this relate to reorder points?
The total lead time here is the lead time to use in a reorder-point calculation, alongside safety stock for delays.
