Why does absorption costing show higher profits when production exceeds sales?

Under absorption costing, some fixed overhead is deferred in ending inventory. If 1,000 units are produced but 800 sold, 200 units of fixed overhead sits on the balance sheet.

Which method is required for external reporting?

Absorption costing is required under GAAP and IFRS for external financial statements. Variable costing is used internally for management decisions and CVP analysis.

When is the income difference largest?

When the change in inventory level is large and fixed overhead per unit is significant. In capital-intensive manufacturing with high production variability, the difference can be material.
