This variance is unfavorable because the actual cost
exceeds the standard cost.
This variance isfavorable because
the actual costis less than thestandard cost.

The activity is the cost driver used to
calculate the overhead rate.
The rate is basedon an estimate of totaloverhead at the normal
level of activity.

For a company using standard costing systems, the accuracy of the inventory and cost of goods sold figures reported in the company’s financial statements is dependent on the reliability of the
standard cost numbers.
