Final answer:
To determine the amount of overapplied or underapplied overhead, calculate the predetermined overhead rate by dividing the budgeted manufacturing overhead by the budgeted cost driver. Then, compare it to the actual manufacturing overhead incurred.
Step-by-step explanation:
To determine the amount of overapplied or underapplied overhead, we need to calculate the predetermined overhead rate and then compare it to the actual manufacturing overhead incurred. The predetermined overhead rate is calculated by dividing the budgeted manufacturing overhead by the budgeted cost driver. In this case, the cost driver is the budgeted direct labor cost. The predetermined overhead rate is $651,000 / $310,000 = $2.10 per dollar of direct labor cost.
The overhead applied would be the actual direct labor cost multiplied by the predetermined overhead rate: $335,000 x $2.10 = $703,500. The difference between the actual manufacturing overhead incurred and the overhead applied gives us the amount of overapplied or underapplied overhead. In this case, it is $535,000 - $703,500 = -$168,500, which means there is an underapplied overhead of $168,500.
