Equipment Payments

Equipment depreciation calculator

Work out how much an asset depreciates each year, by the two standard book methods. Enter the cost, what it will be worth at the end, and how long it lasts, and see the straight-line annual figure, the faster first-year double-declining figure, and the book value after year one, so the paperwork matches the reality.

§ 01 Your numbers

Change anything. The answer updates as you type.

What you paid for the asset, including anything that got it ready to use (delivery, installation).
What it will be worth when you are done with it. Straight-line depreciates down to this figure; zero if it will be worthless.
How many years you expect to use it. This is your estimate for the books; the IRS assigns its own class life for tax.

$2,000 to $8,000 a year is a typical equipment schedule. Confirm the method and life with your accountant for the tax version.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

DEPRECIATION IS A PAPER FIGURE, NOT A CASH ONE.
You paid the cash when you bought the equipment. Depreciation is how that cost is spread across the years the equipment is used, on the books and for tax. It is real in that it lowers your taxable profit each year, but no money moves when you record it, which is exactly why a profitable business can still be short of cash: the depreciation deduction is not money coming in

Straight-line and double-declining are two ways to spread the same total. Straight-line takes an equal slice every year down to salvage. Double-declining front-loads it, taking a bigger deduction early when the equipment arguably loses value fastest, and less later. Over the full life they deduct roughly the same total; they differ in timing.

Salvage value is the floor for straight-line, and your estimate. It is what the asset is worth when you are done with it, and straight-line never depreciates below it. Guess it honestly: too high and you under-deduct, too low and the books say the asset is worthless when it is not.

This is book depreciation, not the tax version. For US taxes, the IRS assigns each asset a class life and a method (MACRS), and Section 179 or bonus depreciation may let you deduct much of the cost in year one instead. Those are the IRS's rules, with dollar limits that change yearly, so the page points to them rather than guessing them.

The defaults are ours and are a starting point. The cost, salvage, and life are yours, and the figures are only as right as those three inputs and the useful life you can honestly claim.

Frequently asked questions

How do I calculate straight-line depreciation?
Subtract the salvage value from the cost to get the depreciable base, then divide by the useful life in years. That is the amount you depreciate each year, equally, until the book value reaches the salvage value. The calculator above does it and also shows the faster double-declining figure for comparison.
What is double-declining balance depreciation?
It is an accelerated method that takes twice the straight-line rate against the asset's remaining book value each year, so the deduction is largest in year one and shrinks after. It suits equipment that loses most of its value early. Over the full life it deducts about the same total as straight-line, just sooner.
What is the difference between book and tax depreciation?
Book depreciation is how you spread the cost on your own financial statements, using a method and life you choose. Tax depreciation follows the IRS: a set class life, the MACRS method, and options like Section 179 and bonus depreciation that can deduct much of the cost immediately. This calculator does the book methods; your accountant handles the tax ones.
Can I deduct the full cost of equipment in one year?
Often, for tax, yes. Section 179 and bonus depreciation can let a US business deduct a large share of an equipment purchase in the year it is placed in service, up to limits that change yearly. That is a tax election, separate from the book depreciation here, and it is worth asking an accountant about before you buy.
