Average Unit Cost Method
The average unit cost method attempts to allocate joint cost among joint products so that each product is allocated the the same per-unit amount of joint cost, called the average unit cost. The average unit cost is obtained by dividing the total number of units produced into the total joint cost. Companies using this method argue that al products generated by the sane process should receive a share of the joint cost proportional to the number of units produced. As long as all the joint products are measured in the same physical unit and do not differ greatly in terms of per-unit market value, this method is reasonable. When the units produced are not measure in like terms or the per-unit market values differ markedly, this method should not be applied.
