Vehicle Depreciation Calculator

About Vehicle Depreciation Calculator

Depreciation spreads the cost of a business asset — equipment, a vehicle, machinery — across its useful life, rather than expensing the full cost the moment it's purchased. This matters for accurate financial reporting and, in many jurisdictions, for tax purposes, since it reflects how the asset actually loses value and gets used up over time rather than all at once.

This tool supports the two most common depreciation methods, and they produce genuinely different schedules. Straight-line depreciation spreads the depreciable amount (cost minus salvage value) evenly across every year of useful life — the simplest method, with the same dollar amount depreciated each year. Double-declining balance depreciation front-loads the expense, depreciating a fixed percentage of the remaining book value each year, which means larger deductions in the early years and progressively smaller ones later.

The choice between methods reflects a real assumption about how the asset loses value: straight-line assumes even wear over time, appropriate for many general assets, while declining balance assumes an asset loses more of its value early on (common for equipment and vehicles that depreciate fastest right after purchase, matching how resale value often actually behaves).

The full year-by-year schedule shows exactly how the book value declines under whichever method you choose, correctly stopping at the salvage value rather than depreciating below it — a detail that matters for the declining balance method especially, since its percentage-based calculation would otherwise overshoot the salvage floor in later years.

How it works

1. Choose straight-line or declining balance. Each produces a genuinely different depreciation schedule.
2. Enter the asset cost, salvage value, and useful life. Salvage value is the estimated worth at the end of its useful life.
3. View the full year-by-year schedule. Depreciation amount and remaining book value for every year.
