How it works

Straight-line: (cost − salvage) / useful life. Declining balance doubles the straight-line rate applied to book value each year. Sum-of-years-digits front-loads depreciation. MACRS (US tax) uses IRS-specified recovery periods and conventions. Depreciation reduces taxable income; accumulated depreciation reduces book value on the balance sheet. Consult a tax advisor for MACRS class assignments.
