Assets lose value over their useful life, and accounting spreads that cost across the years through depreciation. This calculator compares the three common methods — Straight-Line (equal amounts each year), Double Declining Balance (accelerated, more early on) and Sum-of-Years’ Digits (also accelerated) — showing the yearly deduction, the book value over time, and the salvage value at the end.
The method matters because it changes the timing of the expense and therefore of any tax deduction: accelerated methods front-load the deduction, which can be advantageous, while straight-line is simpler and even. Seeing the schedules side by side makes the trade-off clear for a given asset.
It runs in your browser, so your figures stay private. Depreciation rules for tax purposes are jurisdiction-specific, so use this to understand and compare the methods and confirm the allowable treatment with an accountant.
