Computation of equivalent units of production seems to be a difficult problem for many accounting students. There are at least two major reasons for this trouble. First, students attempt to memorize formulas and become confused when, in different courses, they are taught different formulas. Second, students often fail to grasp the basic concept of what "equivalent production" means. In the article a chart has been presented to solve out these problems. One of the formula that has been derived from the chart shows that the equivalent production of any industry depends upon three entities, the material transferred in, equivalent complete units of ending inventory, and equivalent complete units of beginning inventory.
