5. Absorption unit cost

Unit costs are 10 dollars of materials, 5 of labor, 2 of variable overhead, and a 5 dollar fixed overhead rate. Compute the absorption unit product cost.

6. Variable unit cost

Using the same data, compute the variable-costing unit product cost.

7. Production exceeds sales

In a period when production exceeds sales, which method reports higher operating income?

8. Reconciliation rule

Fixed overhead rate is 5 dollars, and inventory rises by 2,000 units during the period. Compute the income difference between absorption and variable costing.

9. GAAP-required method

External financial reporting requires ____ costing, which capitalizes fixed overhead into inventory. One word.

10. Internal preference

Internal decision reports prefer ____ costing because income moves with sales rather than production. One word.
