Interpretation of materials variances

  • interpretation
    • Favorable price variance suggests the company paid less than expected for materials
      • Possible reasons include successfully negotiating better prices with suppliers (volume discounts), changing to more cost-effective suppliers, or experiencing a decrease in market prices for the materials (commodity price fluctuations)
    • Unfavorable price variance indicates the company paid more than expected for materials
      • Possible reasons include unanticipated price increases from suppliers, placing rush orders at premium prices (expedited shipping), or purchasing lower-quality materials at higher prices (substandard materials)
  • interpretation
    • Favorable quantity variance implies the company used less material than expected for the actual output achieved
      • Possible reasons include efficient utilization of materials (minimizing waste), implementing improved production processes (lean manufacturing), or using higher-quality materials that require less usage (durable materials)
    • Unfavorable quantity variance suggests the company used more material than expected for the actual output achieved
      • Possible reasons include excessive waste or spoilage during production (defective units), using lower-quality materials that require more usage (inferior materials), or inefficient production processes (outdated equipment)
