Shelf Life Remaining with daily shipment or depletion rate of 600 units / day: a worked example

Suppose daily shipment or depletion rate falls to 600 units / day. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate required inventory coverage against remaining shelf life, daily demand, and safety stock needs.

The inputs for this scenario

  • Daily shipment or depletion rate: 600 units / day (the input this scenario stresses; the baseline uses 1,200)
  • Usable shelf life left at receipt: 18 days (held at the documented default)
  • Date-code safety stock buffer: 2,500 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Shelf Life Remaining cycle stock = daily shipment or usage rate × remaining usable shelf life.
  • Protected days of supply works out to 0.01 days at these inputs, and this is the headline figure for the scenario.
  • Unprotected days works out to 33.33 days at these inputs.
  • Inventory works out to 600 pieces at these inputs.
  • Daily usage works out to 18 pieces / day at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where daily shipment or depletion rate sits at 1,200 units / day and the headline result is 0.03 days, this scenario comes in 50% below the baseline at 0.01 days.
  • It computes the cycle stock that daily depletion will consume over the remaining usable dating, then adds the date-code safety buffer to show required protected inventory. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
