About the Depreciation Calculator
Calculate asset depreciation with straight-line, double declining balance or sum-of-the-years digits methods. This tool is free, works in your browser and needs no sign-up.
How to use the Depreciation Calculator
Enter the asset cost, salvage value, useful life in years and choose a method. A year-by-year schedule is shown.
Formula used
Straight-line = (Cost − Salvage) ÷ Life. Double declining = Book value × 2 ÷ Life. Sum-of-the-years = (Cost − Salvage) × remaining life ÷ SYD.
Example
With Asset cost 50000, Salvage value 5000, Useful life (years) 5, the calculator shows: Total depreciation = 45,000.00; Final book value = 5,000.00.
Frequently asked questions
Which depreciation method should I use?
Straight-line is simplest and spreads the cost evenly. Declining balance and sum-of-the-years deduct more in early years. Ask your accountant which method your tax rules allow.
Is the Depreciation Calculator free to use?
Yes. It is completely free and you can use it as many times as you like.
How accurate is the Depreciation Calculator?
The calculator uses standard formulas, so the maths is exact. Real life results can differ because of fees, taxes, rounding or personal factors, so treat the answer as an estimate.
