## What room the Main types of Depreciation Methods?

There space several species of depreciation expenseDepreciation ExpenseWhen a long-term asset is purchased, it should be capitalized instead of being expensed in the accounting period it is purchase in. And also different formulas because that determining the book valueBook ValueBook worth is a company’s equity value as report in its jae won statements. The publication value figure is frequently viewed in relation to the of an asset. The most usual depreciation approaches include:

Straight-lineDouble decreasing balanceUnits that productionSum of year digits

Depreciation price is supplied in accountancy to point out the cost of a tangible assetTangible AssetsTangible assets space assets through a physical kind and that organize value. Examples include property, plant, and also equipment. Tangible assets room over its helpful life. In other words, that is the palliation in the worth of one asset the occurs over time as result of usage, wear and also tear, or obsolescence. The 4 main depreciation approaches mentioned above are explained in detail below.

You are watching: Which of the following depreciation methods is not based on the passage of time?

### 1. Straight-Line Depreciation Method

Straight-line depreciationStraight line DepreciationStraight heat depreciation is the most generally used and also easiest technique for allocation depreciation of an asset. Through the right line is a really common, and the simplest, technique of calculating depreciation expense. In straight-line depreciation, the cost amount is the same each year over the valuable life the the asset.

Depreciation Formula because that the straight Line Method:

Depreciation price = (Cost – salvage value) / useful life

Example

Consider a piece of equipment that expenses \$25,000 with an estimated helpful life of 8 years and also a \$0 salvage value. The depreciation expense per year because that this equipment would be together follows:

Depreciation cost = (\$25,000 – \$0) / 8 = \$3,125 every year

### 2. Double Declining Balance Depreciation Method

Compared to various other depreciation methods, double-declining-balance depreciationDouble decreasing Balance DepreciationThe double declining balance depreciation technique is a form of sped up depreciation the doubles the consistent depreciation approach. That is outcomes in a bigger amount expensed in the earlier years as opposed to the later on years of an asset’s useful life. The method reflects the reality that assets room typically an ext productive in their beforehand years than in their later years – also, the practical truth that any kind of asset (think of to buy a car) loses an ext of its value in the first couple of years that its use. V the double-declining-balance method, the depreciation factor is 2x the of the straight-line cost method.

Depreciation formula because that the double-declining balance method:

Periodic Depreciation price = start book worth x price of depreciation

Example

Consider a item of property, plant, and equipment (PP&E)PP&E (Property, Plant and also Equipment)PP&E (Property, Plant, and also Equipment) is one of the main point non-current assets uncovered on the balance sheet. PP&E is impacted by Capex, that prices \$25,000, with an estimated beneficial life that 8 years and a \$2,500 salvage value. To calculation the double-declining balance depreciation, collection up a schedule:

The information on the schedule is described below:

The beginning book worth of the heritage is filled in in ~ the beginning of year 1 and the salvage worth is filled in in ~ the end of year 8.The price of depreciation (Rate) is calculated together follows:

Expense = (100% / helpful life of asset) x 2

Expense = (100% / 8) x 2 = 25%

Note: since this is a double-declining method, we multiply the price of depreciation by 2.

3. Multiply the price of depreciation through the beginning book value to recognize the cost for that year. Because that example, \$25,000 x 25% = \$6,250 depreciation expense.

4. Subtract the expense from the start book value to come at the ending publication value. For example, \$25,000 – \$6,250 = \$18,750 ending book value at the end of the very first year.

5. The ending book value for the year is the start book worth for the complying with year. For example, the year 1 ending publication value the \$18,750 would certainly be the year 2 start book value. Repeat this until the last year of beneficial life.

### 3. Devices of manufacturing Depreciation Method

The units-of-production depreciation an approach depreciates assets based on the total variety of hours provided or the total variety of units to be created by making use of the asset, end its valuable life.

The formula for the units-of-production method:

Depreciation price = (Number that units developed / Life in number of units) x (Cost – rescue value)

Example

Consider a an equipment that expenses \$25,000, v an estimated complete unit manufacturing of 100 million and also a \$0 rescue value. Throughout the very first quarter that activity, the an equipment produced 4 million units.

To calculation the depreciation price using the formula above:

Depreciation cost = (4 million / 100 million) x (\$25,000 – \$0) = \$1,000

### 4. Sum-of-the-Years-Digits Depreciation Method

The sum-of-the-years-digits method is among the sped up depreciation methods. A higher expense is incurred in the early on years and a lower cost in the last years of the asset’s advantageous life.

In the sum-of-the-years digits depreciation methodAccountingOur accounting guides and also resources room self-study travel guide to learn bookkeeping and finance in ~ your very own pace. Browse numerous guides and resources., the remaining life the an legacy is split by the amount of the years and also then multiplied by the depreciating basic to recognize the depreciation expense.

The depreciation formula because that the sum-of-the-years-digits method:

Depreciation cost = (Remaining life / sum of the year digits) x (Cost – rescue value)

Consider the following example to much more easily understand the ide of the sum-of-the-years-digits depreciation method.

Example

Consider a piece of tools that costs \$25,000 and has an estimated advantageous life of 8 years and a \$0 salvage value. To calculation the sum-of-the-years-digits depreciation, collection up a schedule:

The info in the schedule is described below:

The depreciation basic is constant throughout the years and is calculated together follows:

Depreciation basic = cost – rescue value

Depreciation basic = \$25,000 – \$0 = \$25,000

2. The remaining life is simply the staying life of the asset. Because that example, at the beginning of the year, the asset has a staying life that 8 years. The complying with year, the asset has actually a staying life that 7 years, etc.

3. RL / SYD is “remaining life separated by amount of the years.” In this example, the asset has a useful life that 8 years. Therefore, the amount of the years would certainly be 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36 years. The remaining life in the beginning of year 1 is 8. Therefore, the RM / SYD = 8 / 36 = 0.2222.

4. The RL / SYD number is multiply by the depreciating basic to identify the cost for that year.

5. The same is done because that the complying with years. In the beginning of year 2, RL / SYD would be 7 / 36 = 0.1944. 0.1944 x \$25,000 = \$4,861 price for year 2.
