What to Check

  • Cost pool, cost driver, fixed versus variable behavior, direct versus indirect classification, and relevant activity level.
  • Budget, standard cost, variance report, production volume, sales mix, pricing data, and responsibility-center report.
  • Effect on gross margin, contribution margin, break-even point, operating leverage, unit economics, and forecast assumptions.
  • Whether the metric is external reporting, internal management accounting, tax, or operational KPI evidence.
  • Comparability across products, segments, periods, capacity levels, and accounting policies.

Common Mistakes

  • Treating fixed costs as fixed at every activity level.
  • Mixing gross margin, contribution margin, markup, and operating margin.
  • Using budget variance without separating price, volume, mix, and efficiency effects.
  • Applying internal cost metrics as if they were audited external reporting facts.
