Advanced Material Price Variance at 72% share of variance scope included: a worked example

Suppose share of variance scope included falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate price variance for carbon fiber, aramid, core, resin, prepreg, or specialty advanced materials.

The inputs for this scenario

  • Advanced material purchase quantity: 520 lb (held at the documented default)
  • Actual price variance versus standard: 7.4 $ / lb (held at the documented default)
  • Share of variance scope included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed freight, tariff, or surcharge variance: 0 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable advanced material price variance = advanced material purchase quantity × price variance versus standard × variance scope included.
  • total advanced material price variance works out to 2,771 $ at these inputs, and this is the headline figure for the scenario.
  • advanced material price variance per part or job works out to 5.33 $ / piece at these inputs.
  • variable advanced material price variance works out to 2,771 $ at these inputs.
  • fixed freight, tariff, or surcharge variance works out to 0 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of variance scope included sits at 100% and the headline result is 3,848 $, this scenario comes in 28% below the baseline at 2,771 $.
  • It computes total material price variance as the per-pound price gap times pounds purchased times scope, plus a fixed freight, tariff, or surcharge amount. 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

  • total advanced material price variance: 2,771 $ (headline result)
