If you need accumulated depreciation sys, accumulated depreciation and net book value sys and you already have cost of the asset, cost of the asset, expected life/useful life, life of the asset or useful life, number of years, requested year, salvage value and salvage value, this calculator does the substitution for you. It suits a quick check, a homework answer you want to confirm, or any figure you need to sanity test.
What Is the Accumulated Depreciation Calculator?
The accumulated depreciation calculator takes cost of the asset, cost of the asset, expected life/useful life, life of the asset or useful life, number of years, requested year, salvage value and salvage value and turns them into accumulated depreciation sys, accumulated depreciation and net book value sys.
It is the kind of calculation you would otherwise do on the back of an envelope: mechanical, repeatable and easy to get subtly wrong without noticing.
How the Accumulated Depreciation Figure Is Built
Each result is calculated from the ones before it, so the working is fully visible. That matters when the answer is going to be quoted to somebody else and you need to be able to explain where it came from.
The figures are exactly as good as the assumptions underneath them. Check the rates, the periods and the tax treatment before you rely on the result.
Reading the Result Sensibly
A small change in an input can move the result by much more than you would expect, particularly where the calculation divides by one of the figures you supplied. That is worth understanding before you rely on a figure.
For anything that will be committed to, write the inputs down beside the result. A number you can reproduce is worth far more than one you cannot explain.
A Worked Example
Working through an example, with cost of the asset set to 10, cost of the asset set to 5, expected life/useful life set to 2, the calculator returns accumulated depreciation of -9, and net book value of 19, and net book value sys of 5. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out accumulated depreciation sys?
Enter cost of the asset, cost of the asset, expected life/useful life, life of the asset or useful life, number of years, requested year, salvage value and salvage value. The calculator then works through the relationship and reports accumulated depreciation sys, accumulated depreciation and net book value sys.
What does the accumulated depreciation actually calculate?
It takes cost of the asset, cost of the asset, expected life/useful life, life of the asset or useful life, number of years, requested year, salvage value and salvage value and converts them into accumulated depreciation sys, accumulated depreciation and net book value sys using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter cost of the asset?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
