Hi Mike, Standard Cost is the most simple costing method compared to Moving Average and FIFO - simple in term of COGS calculation of Finished Goods. But beyond the simplicity, there is a big demand to come up with a standard cost that is as close as possible to the actual cost and to minimize the variance.
As explained in the last chapter, when actual costs and standard costs differ, the difference is a cost variance. A cost variance can be either favorable or unfavorable. A favorable cost variance results when actual costs are less than standard costs.
