Supply Chain & Procurement worked example

Inventory Turnover with annual cost of goods sold of 1,200,000 $: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop annual cost of goods sold to 1,200,000 $, then walk the calculation through step by step. Calculate inventory turnover for Supply Chain & Procurement from annual COGS and average inventory value.

The inputs for this scenario

  • Annual cost of goods sold: 1,200,000 $ (the input this scenario stresses; the baseline uses 2,400,000)
  • Average inventory value: 300,000 $ (held at the documented default)
  • Normalization factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Inventory turnover = annual COGS ÷ average inventory × normalization factor.
  • Inventory turnover works out to 4 turns at these inputs, and this is the headline figure for the scenario.
  • Raw ratio works out to 4 value at these inputs.
  • Conversion factor works out to 1 x at these inputs.
  • Denominator works out to 300,000 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where annual cost of goods sold sits at 2,400,000 $ and the headline result is 8 turns, this scenario comes in 50% below the baseline at 4 turns.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to annual cost of goods sold, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Turnover is only as good as your average-inventory figure; a single year-end snapshot used as the average can badly misstate velocity for seasonal stock.
