Renewable Material Price Variance at 43% share of volume exposed to price move: a worked example

Suppose share of volume exposed to price move falls to 43%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimates the dollar price variance on renewable-energy raw materials when commodity prices move against the standard cost.

The inputs for this scenario

  • Renewable material volume purchased: 120,000 kg (held at the documented default)
  • Price change per kilogram: 0.85 $/kg (held at the documented default)
  • Share of volume exposed to price move: 43 % (the input this scenario stresses; the baseline uses 60)
  • Fixed re-sourcing / qualification cost: 4,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Price variance = volume x price change per unit x exposed share% + re-sourcing cost.
  • Total renewable material price variance cost works out to 47,860 $ at these inputs, and this is the headline figure for the scenario.
  • Renewable material price variance cost per unit works out to 0.4 $ / piece at these inputs.
  • Variable renewable material price variance cost works out to 43,860 $ at these inputs.
  • Fixed renewable material price variance adder works out to 4,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of volume exposed to price move sits at 60% and the headline result is 65,200 $, this scenario comes in 26.6% below the baseline at 47,860 $.
  • It computes the total dollar price variance on a renewable input as volume times the per-kilogram price change times the exposed share, plus a fixed re-sourcing cost, and divides by volume for a per-unit figure. 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.
