The process involves determining the difference between the standard cost of materials and the actual cost paid for those materials, multiplied by the actual quantity purchased. For instance, if a company standardizes the cost of a raw material at $10 per unit, but actually pays $12 per unit for 100 units, the result indicates an unfavorable discrepancy. This calculation highlights how deviations from planned costs affect overall profitability.
Understanding this discrepancy is crucial for cost control and efficiency management. It enables businesses to identify procurement inefficiencies, vendor performance issues, or unexpected market fluctuations impacting material costs. Historically, such calculations were performed manually, but modern accounting systems automate this process, providing real-time insights that facilitate timely corrective actions and improved budget forecasting.
