Inventory Coverage with ingredient inventory on hand of 600 units: a worked example in nutraceuticals & functional foods

This worked example runs the inventory coverage numbers for a tougher week than the baseline: ingredient inventory on hand of 600 units instead of the typical 1,200 units. Work out how many days of supply an ingredient or finished good gives you from inventory on hand, daily usage, and a safety factor, so planners can time replenishment.

The inputs for this scenario

  • Ingredient inventory on hand: 600 units (the input this scenario stresses; the baseline uses 1,200)
  • Average daily ingredient usage: 85 units / day (held at the documented default)
  • Safety factor: 1.1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Days of supply before safety factor = ingredient inventory on hand รท daily usage.
  • Protected days of supply works out to 6.42 days at these inputs, and this is the headline figure for the scenario.
  • Days of supply before safety factor works out to 7.06 days at these inputs.
  • Ingredient inventory on hand works out to 600 units at these inputs.
  • Daily usage works out to 85 units / day at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where ingredient inventory on hand sits at 1,200 units and the headline result is 12.83 days, this scenario comes in 50% below the baseline at 6.42 days.
  • Use it during weekly purchasing reviews or before committing a production schedule, to confirm each key ingredient covers the supplier lead time plus a buffer. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

  • Protected days of supply: 6.42 days (headline result)
