Phone Depreciation Calculator

Depreciation tells you what an asset — a car, laptop or machine — is worth over time, which matters for resale decisions, business accounts and tax. This Phone Depreciation Calculator calculates depreciation using the straight-line or declining-balance method of your choice.

The calculation applies the chosen depreciation method over the asset's useful life, showing the yearly write-down and the current book value at any point.

In Pakistan, cars are the classic example: a new car loses 10–20% of its value the moment it leaves the showroom, then depreciates more slowly. Knowing the curve helps you time a resale and compare new-versus-used purchases honestly.

For business, depreciation is also a tax concept — the Income Tax Ordinance allows deductions that reduce taxable profit. Track both the accounting and tax treatment, as the rates differ.
