How This Works
Straight-line depreciation spreads an asset's cost evenly over its useful life — the simplest and most common depreciation method. Other methods (declining balance, units of production) front-load or usage-base the expense instead.
Formula
Annual Depreciation = (Cost − Salvage Value) ÷ Useful Life
Example
A $50,000 asset with $5,000 salvage value over 10 years depreciates $4,500 per year, or $375 per month.
