Calculate asset depreciation using Straight-Line, Double Declining Balance, or Sum-of-Years-Digits methods.
Calculate asset depreciation over time with our free calculator, supporting both straight-line and declining balance methods, useful for accounting, tax planning, and business asset tracking.
Straight-Line Depreciation = (Asset Cost − Salvage Value) ÷ Useful Life. Declining Balance applies a fixed percentage to the asset's remaining book value each year, resulting in larger deductions early and smaller ones later.
Straight-line is simpler and spreads cost evenly; declining balance front-loads deductions, useful for assets that lose value faster early on (like vehicles or tech equipment). Check applicable tax rules for your situation.
The estimated resale or scrap value of an asset at the end of its useful life, subtracted from the original cost before spreading depreciation.
Yes, depreciation is typically a deductible business expense, though specific tax rules and allowable methods vary by jurisdiction, consult a tax professional for your specific situation.
Book value reflects the asset's value per accounting records after depreciation; market value is what the asset could actually sell for, the two often differ.
