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)
