Below is a double declining balance method table using straight line depreciation. Remember, in straight line depreciation, salvage value is subtracted from the original cost. If there was no salvage value, the beginning book balance value would be $100,000, with $20,000 depreciated yearly. Whether you are using accounting software, a manual general ledger system, or spreadsheet software, the depreciation entry should be entered prior to closing the accounting period. The method is a little more complicated than the straight-line method. Any silly mistake would lead to an inaccurate charge of depreciation expense.


In addition, capital expenditures consist of not only the new purchase of equipment, but also the maintenance of the equipment. However, one counterargument is that it often takes time for companies to utilize the full capacity of an asset until some time has passed. Accumulated depreciation is the cumulative depreciation of an asset up to a single point in its life.

When to use the double declining depreciation method

The asset’s book value is the asset’s original cost minus the accumulated depreciation. It is based on the principle of accelerating depreciation, meaning that a more significant portion of the asset’s value is depreciated in the early years of its useful life, with depreciation decreasing over time. After a five year recovery period, you’ve completely written it off. Doing some market research, you find you can sell your five year old ice cream truck for about $12,000—that’s the salvage value. To create a depreciation schedule, plot out the depreciation amount each year for the entire recovery period of an asset. Most assets are used consistently over their useful life; thus, depreciating them at an accelerated rate does not make sense.

  • This can make profits seem abnormally low, but this isn’t necessarily an issue if the business continues to buy and depreciate new assets on a continual basis over the long term.
  • Since the double declining balance method has you writing off a different amount each year, you may find yourself crunching more numbers to get the right amount.
  • The accountants at Linear Dynamic will calculate the DDBD for the vehicle using the following values.
  • To calculate the depreciation for successive years, simply repeat the steps above until the salvage value is reached.
  • See the screenshot below for the formulas used in the spreadsheet and the results of the MACRS half-year depreciation calculations.

Under the straight-line depreciation method, the company would deduct $2,700 per year for 10 years–that is, $30,000 minus $3,000, divided by 10. With the constant double depreciation rate and a successively lower depreciation base, charges calculated with this method continually drop. The balance of the book value is eventually reduced to the asset’s salvage value after the last depreciation period. However, the final depreciation charge may have to be limited to a lesser amount to keep the salvage value as estimated. The double-declining balance method is an accelerated depreciation calculation used in business accounting.

Advantages of the Double Declining Balance Method

Companies prefer a double-declining method for assets that are expected to be obsolete more quickly. Though the depreciation expense will be charged at the accelerated rate, total depreciation throughout the life of the asset would remain the same. By accurately reflecting the asset’s value over time, the double declining balance method can help improve the accuracy and clarity of a business’s financial statements. Because the double declining balance method writes off the asset faster, it can generate greater tax benefits in the early years of the asset’s useful life. This can increase a business’s cash flow and allow it to invest in other areas or opportunities. Some businesses argue that the double declining balance method accurately reflects the asset’s value over time.

How do you calculate depreciation less than 180 days?

The rate of additional depreciation would be 20% of the actual cost if the asset is used for 180 days or more. If the asset is used for less than 180 days, the rate would be 10%.

Depreciation is the process by which you decrease the value of your assets over their useful life. The most commonly used method of depreciation is straight-line; it is the simplest to calculate. However, there are certain advantages to accelerated depreciation methods.

Double declining balance vs. the straight line method

Note that the amount for the final period may need to be adjusted downwards so that the salvage value is reached. The value of the asset at the end of the period is the book value at the beginning of the period minus the depreciation amount calculated above. Finally apply a 20% depreciation rate to the carrying value of the asset at the beginning of each year. It’s a common mistake to apply it to the original amount subject to depreciation, but that’s incorrect. Take the $9,000 would-be depreciation expense and figure out what it is as a percentage of the total amount subject to depreciation. You’ll arrive at 0.10, or 10%, by taking $9,000 and dividing it into $90,000.

But before we delve further into the concept of accelerated depreciation, we’ll review some basic accounting terminology. Depreciation is an accounting method of allocating the cost of a tangible asset over its useful life to account for declines in value over time. Both DDB and ordinary declining depreciation are accelerated methods. The difference is that DDB will use a depreciation rate that is twice that the rate used in standard declining depreciation.
