Depreciation Calculator
Enter what the asset cost, what it will be worth at the end, and its useful life.

The three methods
- Straight-line: the same amount every year — (cost − salvage) ÷ life. Simple and widely used in financial statements.
- Declining balance: a fixed percentage of the remaining book value each year (double declining = 2 ÷ life), so more is written off early. The schedule switches to straight-line when that becomes larger, and never goes below the salvage value.
- Sum-of-the-years' digits: also front-loaded; year 1 uses life ÷ (1 + 2 + … + life) of the depreciable amount.
Book value
Book value = cost − accumulated depreciation. Vehicles, computers and machinery lose value fastest in the first years, which accelerated methods reflect.
Tax depreciation follows its own rules: in Pakistan, the Income Tax Ordinance sets initial and normal depreciation rates by asset class, which can differ from the accounting schedule. Ask your accountant which to use for tax returns.
