Metal Recycling, Scrap Processing & Salvage worked example

Yard Inventory Turns with yard inventory turns daily usage of 600 units / day: a worked example

Suppose yard inventory turns daily usage 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 yard inventory turns for metal recycling, scrap processing and salvage using production-ready inputs so teams can plan replenishment and safety stock using actual usage and lead time.

The inputs for this scenario

  • Yard inventory turns daily usage: 600 units / day (the input this scenario stresses; the baseline uses 1,200)
  • Yard inventory turns lead time: 85 days (held at the documented default)
  • Yard inventory turns safety stock: 1.1 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Yard inventory turns cycle stock = yard inventory turns daily usage × yard inventory turns lead time.
  • Protected days of supply works out to 6.42 days at these inputs, and this is the headline figure for the scenario.
  • Unprotected days works out to 7.06 days at these inputs.
  • Inventory works out to 600 pieces at these inputs.
  • Daily usage works out to 85 pieces / day at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where yard inventory turns daily usage sits at 1,200 units / day and the headline result is 12.83 days, this scenario comes in 50% below the baseline at 6.42 days.
  • It sizes required inventory from daily usage, lead time, and safety stock, then expresses on-hand inventory as protected and unprotected days of supply. 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.

Results at a glance

  • Protected days of supply: 6.42 days (headline result)
  • Unprotected days: 7.06 days
  • Inventory: 600 pieces
  • Daily usage: 85 pieces / day
