## What Is Straight-Line Depreciation? Guide & Formula  Sally recently furnished her new office, purchasing desks, lamps, and tables. The total cost of the furniture and fixtures, including tax and delivery, was \$9,000. Sally estimates the furniture will be worth around \$1,500 at the end of its useful life, which, according to the chart above, is seven years. In the last line of the chart, notice that 25% of \$3,797 is \$949, not the \$797 that’s listed. While the purchase price of an asset is known, one must make assumptions regarding the salvage value and useful life. These numbers can be arrived at in several ways, but getting them wrong could be costly. Also, a straight line basis assumes that an asset’s value declines at a steady and unchanging rate. This may not be true for all assets, in which case a different method should be used. The total dollar amount of the expense is the same, regardless of the method you choose. An asset’s initial cost and useful life are also the same using any method.

With the straight line depreciation method, the value of an asset is reduced uniformly over each period until it reaches its salvage value. Straight line depreciation is the most commonly used and straightforward depreciation method for allocating the cost of a capital asset. It is calculated by simply dividing the cost of an asset, less its salvage value, by the useful life of the asset.

Straight-line depreciation is an accounting process that spreads the cost of a fixed asset over the period an organization expects to benefit from its use. Linear interpolation as described here is for data points in one spatial dimension. For two spatial dimensions, the extension of linear interpolation is called bilinear interpolation, and in three dimensions, trilinear interpolation. Other extensions of linear interpolation can be applied to other kinds of mesh such as triangular and tetrahedral meshes, including Bézier surfaces.

## Depreciation examples

Some assets experience accelerated obsolescence in their early years, such as computers and vehicles. Note how the book value of the machine at the end of year 5 is the same as the salvage value. Over the useful life of an asset, the value of an asset should depreciate to its salvage value. Company A purchases a machine for \$100,000 with an estimated salvage value of \$20,000 and a useful life of 5 years. Divide the sum of step by the number arrived at in step to get the annual depreciation amount. This lerp function is commonly used for alpha blending (the parameter “t” is the “alpha value”), and the formula may be extended to blend multiple components of a vector in parallel.

For example, due to rapid technological advancements, a bookkeeping services method may not be suitable for an asset such as a computer. It would be inaccurate to assume a computer would incur the same depreciation expense over its entire useful life. When you purchase the asset, you’ll post that transaction to your asset account and your cash account, creating a contra account in order to keep track of your accumulated depreciation. You can then record your depreciation expense to the general ledger while crediting the accumulated depreciation contra-account for the monthly depreciation expense total. Straight line depreciation is the easiest depreciation method to calculate. While it can be useful to use double declining or other depreciation methods, those methods also present more complex formulas, which can result in errors, particularly for those new to depreciation. In addition to this, learn more about ways to calculate the expense, and how depreciation impacts financial statements. Accountants prefer the straight line basis because it is easy to calculate and understand. The method allocates an even amount to each accounting period over the asset’s useful life making it a predictable expense, and allows for the smoothing of net income.

## Changes in balance sheet activity

Straight line basis is the simplest technique used to compute the value loss of an asset over its useful life. Also called straight line depreciation, straight line basis charges an equal expense amount to each accounting period. It assumes that the asset’s value diminishes equally over each accounting period during its useful life. Since the asset is uniformly depreciated, it does not cause the variation in the Profit or loss due to depreciation expenses. In contrast, other depreciation methods can impact Profit and Loss Statement variations.

To calculate depreciation using a straight line basis, simply divide net price by the number of useful years of life the asset has. Divide the depreciable asset cost by the number of years the asset is estimated to be in use. There are a lot of reasons businesses choose to use the straight line depreciation method. It allows you to reduce the value of a tangible asset, thereby lowering your total expenses . Under the straight-line method, the depreciable basis is divided by the number of years in the asset’s life in order to determine the average annual expense. When usage is the key factor retail accounting in calculating depreciation, use the units-of-production method.

Straight line basis is a depreciation method used to calculate the wearing out of an asset’s value over its serviceable lifespan by assuming an equal depreciation expense each accounting period. Balance SheetA balance sheet is one of the financial statements of a company that presents the shareholders’ equity, liabilities, and assets of the company at a specific point in time. It is based on the accounting equation that states that the sum of the total liabilities and the owner’s capital equals the total assets of the company. Accountants use the straight line depreciation method because it is the easiest to compute and can be applied to all long-term assets. However, the straight line method does not accurately reflect the difference in usage of an asset and may not be the most appropriate value calculation method for some depreciable assets.

They are typically high-cost items, and depreciation is meant to smooth out their costs over the time they will be in service. This helps to avoid wild swings in cash balances and profitability on a company’s financial statements that can be caused by expensing all at once. Straight-line depreciation is the simplest method for calculating depreciation because it assumes that the asset will decline in usefulness on a constant basis from period to period.

## How to Graph a Straight Line Using its Equation?

So, the amount of depreciation declines over time, and continues until the salvage value is reached. Straight line depreciation is the easiest depreciation method to use, making it ideal for small businesses that need to depreciate fixed assets. One of the great things about real estate investing is that it offers a lot of significant tax advantages that other investments don’t.

Carrying ValueCarrying value is the book value of assets in a company’s balance sheet, computed as the original cost less accumulated depreciation/impairments. It is calculated for intangible assets as the actual cost less amortization expense/impairments. Other methods of depreciation include units of production, sum of the years’ digits, declining balance and modified accelerated cost recovery systems . All of these methods are GAAP-compliant except for MACRS, which is required by the IRS for U.S. tax purposes. Simplicity aside, the nature of a fixed asset often makes straight-line depreciation the most fitting choice. When a fixed asset’s obsolescence is simply the result of time passing, straight-line depreciation is an appropriate method.

• It results in fewer errors, is the most consistent method, and transitions well from company-prepared statements to tax returns.
• It is easiest to use a standard useful life for each class of assets.
• Also, a straight line basis assumes that an asset’s value declines at a steady and unchanging rate.
• In this case, the depreciable base is the \$50,000 cost minus the \$10,000 salvage value, or \$40,000.
• To record the purchase of the copier and the monthly depreciation expense, you’ll need to make the following journal entries.

It is believed that it was used in the Seleucid Empire and by the Greek astronomer and mathematician Hipparchus . Sally can now record straight line depreciation for her furniture each month for the next seven years. Below, we’ve provided you with some straight line depreciation examples. If you don’t expect the asset to be worth much at the end of its useful life, be sure to figure that into the calculation. Sara runs a small nonprofit that recently purchased a copier for the office. It cost \$150 to ship the copier, and the taxes were \$600, making the final cost of the copier \$8,250.

## FAQs on Slope Formula

Therefore, depreciation would be higher in periods of high usage and lower in periods of low usage. This method can be used to depreciate assets where variation in usage is an important factor, such as cars based on miles driven or photocopiers on copies made. Straight line amortization is the same as straight line depreciation, except that it applies to intangible assets, rather than tangible assets. In accounting, there are many differentconventionsthat are designed to match sales and expenses to the period in which they are incurred. One convention that companies embrace is referred to asdepreciation and amortization. The expenses in the accounting records may be different from the amounts posted on the tax return.

Use the standard straight-line depreciation formula, below, to calculate annual depreciation expense. It has wide application to many fixed assets, especially when their obsolescence is simply due to passage of time. The units of production method is based on an asset’s usage, activity, or units of goods produced. “Salvage value” is the cash you receive when you sell the asset at the end of its useful life. Then, you divide \$1,500 by five years, to reach an annual depreciation of \$300. There are many methods of distributing depreciation amount over its useful life. While these lives are required to be used for income tax purposes, they aren’t required for bookkeeping.

Then divide the resulting figure by the total number of years the asset is expected to be useful, referred to as the useful life in accounting jargon. The straight-line depreciation method posts an equal amount of expenses each year of a long-term asset’s useful life. Business owners use it when they cannot predict changes in the amount of depreciation from one year to the next. After the machine’s useful life is over, the asset’s carrying value will be only \$ 2000. The management will sell the asset, and if it is sold above the salvage value, a profit will be booked in the income statement, or else a loss if sold below the salvage value.

To record the purchase of the copier and the monthly depreciation expense, you’ll need to make the following journal entries. Things wear out at different rates, which calls for different methods of depreciation, like the double declining balance method, the sum of years method, or the unit-of-production method. The next step in the calculation is simple, but you have to subtract the salvage value. In some scenarios, subsequent journal entries may change due to adjustments to the fixed asset’s useful life or value to the company as a result of improvements or impairments of the asset. For example, during year 5 the company may realize the asset will only be useful for 8 years instead of the originally estimated 10 years.
