SLM of Depreciation vs. WDV Method of Depreciation

Key Differences

SLM, or Straight Line Method, of Depreciation involves depreciating an asset at a fixed annual rate, resulting in equal depreciation charges each year. The WDV Method, or Written Down Value Method, depreciates assets at a fixed percentage, leading to decreasing annual charges as the asset's value reduces.

Under SLM, the cost of the asset is evenly spread over its useful life, providing a consistent depreciation expense each year. In contrast, WDV provides higher depreciation expenses in the early years, decreasing as the asset ages.
