Inventory Valuation Impact at 6.9% revaluation swing: a worked example

What does the result look like when revaluation swing reaches 6.9%? The full calculation is worked below with real intermediate numbers. Use it when a material-cost update or annual standard reset forces a restatement of on-hand inventory value.

The inputs for this scenario

  • SKUs revalued: 450 SKUs (unchanged)
  • Carrying value per SKU: 3,200 $ / SKU (unchanged)
  • Revaluation swing: 6.9 % (raised for this scenario; the documented default is 6)
  • Write-down reserve adder: 15,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Valuation impact = SKUs x carrying value x revaluation swing% + reserve adder) to the inputs above produces each figure below.
  • At this operating point the engine returns 114,360 $ for total inventory valuation impact cost, the number this scenario is built around.
  • At this operating point the engine returns 254 $ / piece for inventory valuation impact cost per unit.
  • At this operating point the engine returns 99,360 $ for variable inventory valuation impact cost.
  • At this operating point the engine returns 15,000 $ for fixed inventory valuation impact adder.

How this compares with the baseline

  • Against the tool's baseline example, where revaluation swing sits at 6% and the headline result is 101,400 $, this scenario comes in 12.78% above the baseline at 114,360 $.
  • A figure at this level is achievable when revaluation swing is genuinely sustained, not just peaked for a shift. It applies one average carrying value and one swing across all SKUs; in reality the swing varies by item, so use it for sizing, not for the final per-SKU posting.
