Craig Company uses a predetermined overhead rate to assign overhead to jobs. Because Craig's production is machine intensive, overhead is applied on the basis of machine hours. The expected overhead for the year was $5,702,400, and the practical level of activity is 396,000 machine hours. During the year, Craig used 404,000 machine hours and incurred actual overhead costs of $5,739,600. Craig also had the following balances of applied overhead in its accounts: Work-in-process inventory $ 550,560 Finished goods inventory 609,760 Cost of goods sold 1,799,680 Required: 1. Compute a predetermined overhead rate for Craig. Round your answer to the nearest cent. $ 14.4 per machine hour 2. Compute the overhead variance, and label it as under- or overapplied.

1. $14.4 per machine hour

2. $78,000 over-applied

Explanation:

The computation is shown below:

1. Predetermined overhead rate = (Expected overhead for the year) ÷ (practical level of activity)

= $5,702,400  ÷ 396,000 machine hours

= $14.4

b. The overhead variance is

For computing the overhead variance, first we have to determine the applied overhead that is given below

= Actual machine hours × predetermined overhead rate

= 404,000 machine hours × $14.4

= $5,817,600

So, the overhead variance equals to

= Actual manufacturing overhead - actual overhead

= $5,739,600 - $5,817,600

= $78,000 over-applied

$45,000 per year is the economic cost of the time he contributes to the new business.

The difference between the accounting cost and the implicit cost refers to the economic cost. Implicit cost refers to the opportunity cost that the person incurs when he makes a choice. For example consider Geetha is spending something for watching a movie. The cost that she spends for the movie and the cost that can be forgone by her when she spends that for some other things will be included in the economic cost.

In the example given Jim  was earning d $70,000 per year and now he is paying himself  $25,000 per year for building a new business. Thus the economic cost will be $70,000 -$25,000 = $45,000 per year. Here the accounting cost is  $70,000  and the implicit cost is $25,000.
