Answer: $1,900 less than under absorption costing.
Step-by-step explanation:
The ending inventory of finished goods under variable costing is the difference in carrying value of ending finished goods inventory.
That is calculated as,
Difference in Carrying Value of Ending Finished Goods Inventory = Unit fixed Manufacturing Overhead * Change in Inventory in Units
The Unit Fixed Manufacturing Overhead as implied is the fixed Manufacturing Overhead per unit
Calculated therefore as,
Unit fixed manufacturing overhead = 129,010 / 6,790
= $19
Now that we have that, we can refer back to thw first formula,
Difference in carrying value of ending finished goods inventory = Unit fixed manufacturing overhead * Change in inventory in units
= 19 × (6,790 - 6,690)
= $1,900
The carrying value on the balance sheet of the ending inventory of finished goods under variable costing would be $1,900 less than under absorption costing.
