3. 2014 operating income under absorption costing is greater than the operating income under
variable costing because in 2014 inventory increased by 500 units. As a result, under absorption
costing, a portion of the fixed overhead remained in the ending inventory and led to a lower cost
of goods sold (relative to variable costing). As shown below, the difference in the two operating
incomes is exactly the same as the difference in the fixed manufacturing costs included in ending
versus beginning inventory (under absorption costing).
Operating income under absorption costing
$1,573,150
Operating income under variable costing
1,543,150
Difference in operating income under absorption versus variable
costing
$ 30,000
Under absorption costing:
Fixed mfg. costs in ending inventory (500 units
$60 per unit)
$ 30,000
Fixed mfg. costs in beginning inventory (0 units
$60 per unit)

Change in fixed mfg. costs between ending and beginning inventory
$ 30,000
