Depreciation FAQs
Common questions about depreciation
Straight-line depreciation allocates an equal amount of depreciation expense each period. Formula: (Cost - Salvage Value) / Useful Life. It's the simplest and most commonly used method.
Accelerated methods like double-declining balance are used when assets lose more value in early years. This often better matches the actual decline in an asset's productive capacity and provides larger tax deductions early on.
Accumulated depreciation is a contra-asset account that tracks total depreciation recorded over an asset's life. It's subtracted from the asset's cost to determine book value (carrying value) on the balance sheet.
