About this tool
Enter cost, salvage value, useful life, and years elapsed, and the tool gives annual depreciation and current book value. This is a straight-line estimate for planning, not tax advice; tax rules and allowable methods vary, so check current rules before filing.
Frequently asked questions
Does this method fit tax reporting?
Not always. Tax authorities may require different methods or lives, so check current rules for your situation.
What if the asset lasts longer than planned?
Keep its book value at salvage value and stop depreciating, then review the life estimate for similar assets.
