Introduction
Depreciation allocates the cost of tangible assets over useful life for accounting and tax. Enter cost, salvage value, life, and method to generate schedules.
Asset Depreciation
Depreciation allocates the cost of tangible assets over useful life for accounting and tax. Enter cost, salvage value, life, and method to generate schedules.
Methods
- Straight line: equal expense each year.
- Declining balance (200%): more expense early.
- Sum-of-years-digits: accelerated but smoother than DDB.
Partial First Year
Enable placed-in-service month to prorate year-one depreciation when assets start mid-year - required for many tax returns.
Tax vs Books
MACRS tax depreciation differs from book methods. Consult a CPA for filing; this tool teaches mechanics.
Book Value
Ending book value equals cost minus accumulated depreciation. Salvage value sets the floor below which the asset is not depreciated further under straight line.
