Depreciation Formulas
Straight-Line
Annual = (Cost - Salvage) / Life
Example: ($10,000 - $1,000) / 5 = $1,800/year
Double Declining
Depreciation = Book Value × (2 / Life)
Example: $10,000 × (2/5) = $4,000 first year
Sum-of-Years-Digits
Depreciation = (Remaining/Sum) × Depreciable Cost
Example: (5/15) × $9,000 = $3,000 first year
MACRS
Depreciation = Cost × MACRS Rate for Year
Example: $10,000 × 20% = $2,000 first year (5-year)
