What is Asset Depreciation?
Depreciation is the systematic allocation of an asset's cost across its useful life — it's how accountants match the expense of long-lived equipment, vehicles, or property to the periods that benefit from them. Different methods produce dramatically different schedules: straight-line gives equal annual deductions, while declining-balance and double-declining-balance front-load the expense, and sum-of-years-digits sits between them. The right method depends on tax strategy, financial-reporting standards (GAAP vs IFRS), and how the asset's economic value actually erodes. This calculator runs every method side-by-side over the asset's full life so you can pick the schedule that matches reality. Pair it with the Loan Calculator to model the financing side, or the Budget Calculator to allocate the depreciation expense across the year.
