Answer:
1. Compute the
(a) budgeted indirect-cost rate
$40 per labor hour
and (b) actual indirect-cost rate.
$42 per labor hour
Why do they differ?
Because total assembly support costs and labor hours were different.They both were actually lower than expected, but the labor hours were 9% lower while the costs were around 5% lower. That is why the actual rate increased (denominator decreased more than numerator).
2. What are the job costs of the Laguna Model and the Mission Model using (a) normal costing
Laguna Model Mission Model
assembly-support cost $38,800 $40,000
and (b) actual costing?
Laguna Model Mission Model
assembly-support cost $40,7400 $42,000
3. Why might Atkinson Construction prefer normal costing over actual costing?
The problem with actual costing is that they cannot be budgeted, you can only budget normal costing. Any business has to prepare budgets in order to control how their operations are being carried out and then they need to adjust them to the actual costs incurred.
Explanation:
Laguna Model Mission Model
Construction period Feb-June 2017 May-0ct 2017
Direct material costs $106,550 $127,450
Direct labor costs $36,250 $41,130
Direct labor-hours 970 1,000
budgeted indirect cost rate:
assembly-support costs $8,800,000
direct labor-hours 220,000
budgeted assembly-support cost per labor hour = $8,800,000 / 220,000 = $40 per hour
Laguna Model Mission Model
assembly-support cost $38,800 $40,000
actual indirect cost rate:
assembly-support costs $8,400,000
direct labor-hours 200,000
actual assembly-support cost per labor hour = $8,400,000 / 200,000 = $42 per hour
Laguna Model Mission Model
assembly-support cost $40,7400 $42,000
