Frequently asked questions
Straight-line spreads the cost evenly across the asset's useful life, so each year's expense is the same. Declining balance is accelerated: it applies a fixed percentage to the remaining book value each year, so expense is highest early and tapers off. This calculator supports both, including double-declining (200%) and 150% factors.
Subtract the salvage value from the asset cost to get the depreciable base, then divide by the useful life in years. For example, a $20,000 asset with a $2,000 salvage value over 5 years depreciates $18,000 ÷ 5 = $3,600 per year, leaving $2,000 of book value at the end.
Declining balance applies a percentage to a shrinking book value, so mathematically it never hits zero on its own. This calculator caps each year so the asset is never depreciated below its salvage value — once book value reaches salvage, depreciation stops.
No. These are planning estimates only, not tax, accounting, or professional advice. Allowed methods, recovery periods, and conventions (such as MACRS in the US or capital allowances elsewhere) vary by country and asset type. Confirm the correct treatment with a qualified accountant or your local tax authority.
