Technical notes
Depreciation Calculator applies the method you choose — straight-line (cost − salvage)/life or declining-balance (rate × book value) — to find each period's expense and the remaining book value.
Uses the cost, salvage value and useful life you enter; tax rules and depreciation methods vary.
Nothing you type is uploaded — the calculation happens entirely on your device.
Worked example
An asset costing 100,000 with a 10,000 salvage over 5 years (straight-line) depreciates (100,000 − 10,000) ÷ 5 = 18,000/year.
FAQ
How do the two depreciation methods differ?
Straight-line spreads the depreciable amount evenly across the life, while double-declining-balance applies a higher rate to the book value, front-loading the expense.
Does the Depreciation Calculator send my data to a server?
No. The Depreciation Calculator runs entirely in your browser with JavaScript; the values you enter never leave your device and nothing is uploaded or saved.
How is double-declining-balance computed?
The first-year charge is the book value times two divided by the life, and the tool stops it from reducing book value below the salvage figure.
Which method should I choose?
Straight-line suits assets that wear evenly; double-declining suits assets that lose value fastest early on, but your accounting rules may dictate the method.
