Standard costing is a technique that involves setting standards for costs, comparing actual costs to standards, investigating variances, and taking corrective action. It involves establishing standard costs per unit for direct materials, direct labor, and overhead. Actual costs are then compared to standards and any differences or variances are identified. Variances can be investigated to determine where costs differed from standards and actions can be taken to remedy issues. Standard costing can be used with both absorption and marginal costing systems.
