What is the Depreciation Calculator?
Depreciation spreads the cost of an asset over its useful life. The calculator builds a schedule using straight-line, declining-balance or sum-of-the-years-digits methods.
Where the Depreciation Calculator fits
Calculate depreciation by straight-line, declining-balance or sum-of-the-years-digits with a full schedule. The main figure it returns is the First-year depreciation, worked out from the values you enter.
It belongs with the other business & everyday tools tools. If you are comparing options or checking a result from another angle, try the Margin Calculator, Commission Calculator or the Percentage Calculator.
How to use the Depreciation Calculator
- Enter your numbers. The inputs are Asset cost ($), Salvage value ($), Useful life (years), First year of use. Use real figures from your own records where you can. Fields marked optional can stay at zero.
- Choose your options. Method, Declining-balance rate change how the result is worked out, and the form updates to match your choice.
- Read the result. The highlighted box gives the First-year depreciation, and the cards below show Depreciable amount, Annual (straight-line), Final book value. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
