About this calculator
Fixed business assets (machinery, vehicles, computers, office furniture) lose economic value over time. Tax regulations and accounting standards allow businesses to write off this asset cost across its designated useful lifespan.
This calculator compares straight-line depreciation (equal annual expense) against accelerated methods (Double Declining Balance and Sum-of-the-Years'-Digits) to help maximize early-year tax deductions.
How It Works & Formula
Straight-Line: (Cost - Salvage) / Life. Double Declining: Book Value × (2 / Life). Sum-of-the-Years'-Digits: (Cost - Salvage) × (Remaining Life / SYD), where SYD = n(n+1)/2.
