Amortization is different from depreciation in that it applies to:

Amortization specifically refers to the process of gradually writing off the initial cost of intangible assets over a specified period. Intangible assets may include items like patents, trademarks, or goodwill, which do not have a physical presence and typically do not have a definitive lifespan compared to tangible assets.

In contrast, depreciation relates to the allocation of the cost of tangible assets with a finite useful life, such as machinery or buildings, which are physical in nature. Therefore, the distinction lies in the types of assets being considered: amortization applies to intangible assets, often characterized by their indefinite or uncertain life, whereas depreciation is concerned with the physical assets that wear down over time.

This understanding clarifies the role of amortization in financial accounting and reporting, particularly in recognizing expenses tied to intangible investments over time.
