What is the Straight Line Method (SLM) of depreciation?

SLM spreads depreciation evenly over an asset's useful life. Annual Depreciation = (Cost - Salvage Value) / Useful Life. Suitable for assets that depreciate uniformly.

What is the Written Down Value (WDV) method?

WDV applies a fixed percentage on the book value at the start of each year, resulting in higher depreciation in early years and lower in later years. Widely used under Income Tax Act in India.

What is Double Declining Balance (DDB) depreciation?

DDB is an accelerated depreciation method that applies twice the SLM rate on the declining book value each year. It's commonly used in GAAP financial reporting for assets that lose value faster in early years.
