Book value never drops below salvage value. This is book/educational depreciation, not US tax MACRS (which uses IRS tables and half-year conventions) — do not use it to file a return.

How it works

  1. 1

    Enter the asset

    Add the cost, the salvage value at end of life and the useful life in years.

  2. 2

    Pick a method

    Use straight-line, or switch to 150% or double declining balance.

  3. 3

    Read the schedule

    See the annual depreciation and a table of book value year by year.

Frequently asked questions

How do I calculate straight-line depreciation?
Subtract salvage value from the cost, then divide by useful life in years. A $50,000 asset with $5,000 salvage over 10 years depreciates $4,500 a year.
What is salvage value?
Salvage value is the estimated worth of an asset at the end of its useful life, what you expect to sell or scrap it for. It is subtracted from cost before depreciation is spread out.
What is double declining balance?
It applies twice the straight-line rate to each year’s opening book value, front-loading the depreciation. A 5-year asset depreciates at 40% of book value a year before tailing off.
Is this the same as tax depreciation?
No. US tax depreciation uses MACRS conventions with IRS tables and half-year rules. This tool is for book and educational estimates, not for filing a tax return.
Is this financial advice?
No. These are estimates to help you plan and compare options. Your real figures depend on your lender, taxes and personal situation, so check with a qualified professional before deciding.
