Final answer:
The commonly used depreciation methods are straight-line, declining-balance, and increasing-balance. Straight-line depreciation spreads the cost of an asset equally over its useful life, while declining-balance and increasing-balance depreciation methods allow for larger or smaller expenses in the early years, gradually decreasing or increasing over time.
Step-by-step explanation:
The commonly used depreciation methods are: Straight-line, Declining-balance, and Increasing-balance. Let's briefly explain each of these methods:
- Straight-line depreciation: This method spreads the cost of an asset equally over its useful life. It is the simplest and most commonly used method.
- Declining-balance depreciation: This method allows for larger depreciation expenses in the early years of an asset's useful life, gradually decreasing over time.
- Increasing-balance depreciation: This method is less commonly used and allows for smaller depreciation expenses in the early years, gradually increasing over time.
Methods such as declining-balance and straight-line are frequently employed in various businesses to reflect the consumption of an asset's useful life over time. The straight-line method spreads the cost evenly over the asset's life, while declining-balance accelerates depreciation at a higher rate in the early years. The activity-based method depreciates assets based on usage rather than time.
The options 'c. Value-based' and 'e. Increasing-balance' are not standard depreciation methods.
