Normal absorption costing is a commonly used accounting method to allocate costs to products or services by absorbing them into the cost of goods sold. However, there are several synonyms for this term, including full absorption costing, traditional costing, and full cost accounting. Each of these methods works on the same principle - all production-related costs are included in the cost of goods sold. The aim is to provide a clear view of how much it costs to produce something. However, it is essential to note that while synonyms may differ in terminology, they all represent the same concept in accounting.
