- The planned or expected costs. Often used in manufacturing for accounting for inventories and production. When actual costs differ from the standard costs, variances are reported.
- Standard costs are usually associated with a manufacturing company's costs of direct material, direct labor, and manufacturing overhead.
- Rather than assigning the actual costs of direct material, direct labor, and manufacturing overhead to a product, many manufacturers assign the expected or standard cost. This means that a manufacturer's inventories and cost of goods sold will begin with amounts reflecting the standard costs, not the actual costs, of a product. Manufacturers, of course, still have to pay the actual costs. As a result there are almost always differences between the actual costs and the standard costs, and those differences are known as variances.
Standard costing and the related variances is a valuable management tool. If a variance arises, management becomes aware that manufacturing costs have differed from the standard (planned, expected) costs.
The sooner that the accounting system reports a variance, the sooner that management can direct its attention to the difference from the planned amounts.
