How does a depreciation calculator work?

A depreciation calculator subtracts estimated salvage value from the initial asset cost and divides that net depreciable base across the asset's useful life using your chosen accounting method.

What is the difference between straight-line and accelerated depreciation?

Straight-line depreciation spreads expenses evenly across every year, whereas accelerated methods (like Double Declining Balance) write off larger tax deductions in early years.

What is salvage value in asset depreciation?

Salvage value is the estimated dollar amount an asset can be sold for after it reaches the end of its useful operational life.

Is this asset depreciation calculator free to use?

Yes, this tool operates 100% free with all schedule calculations executing client-side in your web browser.

Can an asset's book value drop below its salvage value?

No, under standard accounting rules, an asset stops depreciating once its book value reaches its predetermined salvage value.

What is the MACRS depreciation method?

MACRS (Modified Accelerated Cost Recovery System) is the standard US tax depreciation system that accelerates deductions for business equipment and real estate property.

Why do businesses record depreciation expenses?

Depreciation matches the expense of acquiring an asset to the revenues that asset generates over its useful life, providing an accurate representation of net income on income statements.

The Straight-Line Depreciation Formula

\text{Straight-Line Depreciation} = \frac{\text{Asset Cost} - \text{Salvage Value}}{\text{Useful Life (Years)}}

If equipment costs $50,000, has a $5,000 salvage value, and a 5-year useful life, annual depreciation expense is $9,000 per year [($50,000 - $5,000) / 5 = $9,000].
