double declining balance equation

Under thedouble declining balance method the 10% straight line rate is doubled to 20%. However, the 20% is multiplied times the fixture’s book value at the beginning of the year instead of the fixture’s original cost. When you run a business, you have to be aware of the useful life of your assets. Some assets have lives that last for decades, while others can only be counted on for a few years. Depending on the asset, you may want to consider using the double declining balance depreciation method. This method accounts for assets that lose their value quickly.

Because of the high number of miles you expect to put on the truck, you estimate its useful life at five years. This formula works for each year you are depreciating an asset, except for the last year of an asset’s useful life. In that year, the amount to be depreciated will be the difference between the book value of the asset at the beginning of the year and its final salvage value . The DDB depreciation method is best applied to assets that quickly lose value in the first few years of ownership. This is most frequently the case for things like cars and other vehicles but may also apply to business assets like computers, mobile devices and other electronics. This method requires taking the useful life of an asset and adding up the number of each year (e.g., 5+4+3+2+1 for a five-year useful life).

Double Declining Balance Depreciation Formulas

Deduct the annual depreciation expense from the beginning period value to calculate the ending period value. (An example might be an apple tree that produces fewer and fewer apples as the years go by.) Naturally, you have to pay taxes on that income. But you can reduce that tax obligation by writing off more of the asset early on. As years go by and you deduct less of the asset’s value, you’ll also be making less income from the asset—so the two balance out. Use this calculator to calculate the accelerated depreciation by Double Declining Balance Method or 200% depreciation.

Under the DDB method, we don’t consider the salvage value in computing annual depreciation charges. Instead, we simply keep deducting depreciation until we reach the salvage value. As you can see, the depreciation rate is multiplied by the asset book value every year to compute the deprecation expense. The expense is then added to the accumulated depreciation account. The double declining depreciation rate would equal 20 percent. Once the asset is valued on the company’s books at its salvage value, it is considered fully depreciated and cannot be depreciated any further.

Prorating Depreciation

In this case, consider the first month as being +$200 and the second month being -$200. Unlike straight line depreciation, which stays consistent throughout the useful life of the asset, double declining balance depreciation is high the first year, and decreases each subsequent year. In the Declining Balance method, LN calculates each year’s total depreciation by applying a constant percentage to the asset’s net book value. The declining balance methods allocate the largest portion of an asset’s cost to the early years of its useful life. Assume a company purchases a piece of equipment for $20,000 and this piece of equipment has a useful life of 10 years and asalvage valueof $1,000.

If something unforeseen happens down the line—a slow year, a sudden increase in expenses—you may wish you’d stuck to good old straight line depreciation. While double declining balance has its money-up-front appeal, that means your tax bill goes up in the future. Depreciation is an accounting process by which a company allocates an asset’s cost throughout itsuseful life.

Double Declining Balance Depreciation

In year 5, companies often switch to straight-line depreciation and debit Depreciation Expense and credit Accumulated Depreciation for $6,827 ($40,960/6 years) in each of the six remaining years. You would take $90,000 and divide it by the number of years the asset is expected to remain in service under the straight-line method—10 years in this case. Take the $100,000 asset acquisition value and subtract the $10,000 estimated salvage value. 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. Mary Girsch-Bock is the expert on accounting software and payroll software for The Ascent. Straight line depreciation expense remains the same every year.

If there was no salvage value, the beginning book balance value would be $100,000, with $20,000 depreciated yearly. This approach is reasonable when the utility of an asset is being consumed at a more rapid rate during the early part of its useful life. It is also useful when the intent is to recognize more expense now, thereby shifting profit recognition further into the future . Tim worked as a tax professional for BKD, LLP before returning to school and receiving his Ph.D. from Penn State. He then taught tax and accounting to undergraduate and graduate students as an assistant professor at both the University of Nebraska-Omaha and Mississippi State University.

When the $80,000 is multiplied by 20% the result is $16,000 of depreciation for Year 2. You might be confused about why the purchase of an expensive asset isn’t considered an outright expense. This is because of the generally accepted accounting principles, or GAAP. GAAP states that when an asset is to be used for many years, the purchase needs to be deducted over time. This method takes most of the depreciation charges upfront, in the early years, lowering profits on the income statement sooner rather than later.

As these assets age, their depreciation rates slow over time. In these situations, the declining balance method tends to be more accurate than the straight-line method at reflecting book value each year.

This method is double of declining or reducing balance method and hence, generally also termed as 200% declining balance method. However, the asset will be depreciated up to its scrap value only. The accumulated depreciation of an asset is the amount of cumulative depreciation charged on the asset from its purchase date until the reporting date. It is a contra-account, the difference between double declining balance method the asset’s purchase price and its carrying value on the balance sheet. Basic yearly write-off/cost of the asset The result is yourbasic depreciation rate expressed as a decimal. (You can multiply it by 100 to see it as a percentage.) This is also called the straight-line depreciation rate—the percentage of an asset you depreciate each year if you use the straight-line method.
