1. How Capital Asset Depreciation Works
Asset depreciation represents the systematic reduction of an asset's balance sheet value over its determined useful life. Rather than deducting the entire purchase price of a major asset (like vehicles, properties, or servers) in year one, businesses distribute the cost matching revenue output periods.

Accounting frameworks support different rates of capital write-down:
- Straight-Line Depreciation: Reduces book values by a fixed, constant amount each period. It is simple, clear, and is the default choice for standard operations.
- Double Declining Balance (DDB): An accelerated method that writes down values at twice the straight-line rate, focusing major deductible expenses in early life cycles when asset wear is highest.
- Sum-of-the-Years' Digits (SYD): A smooth declining balance model using historical useful life index fractions. Writes down asset balances progressively.
3. Residual Salvage Valuation
Salvage value represents what the business expects to recoup by selling or scrapping the asset at the end of its useful lifespan. The depreciable base is isolated by subtracting this expected residual return from the initial capital placement cost.
