Depreciation Methods

Depreciation spreads the cost of an asset over its useful life. This calculator supports two common methods used for bookkeeping and tax planning estimates.

Straight-Line

Equal depreciation each year: (Cost − Salvage) ÷ Useful Life. Simple and predictable.

Double Declining Balance

Accelerated depreciation: each year applies twice the straight-line rate to the remaining book value, stopping at salvage value.
