Fixed Assets & Depreciation | Accounting Principles

Fixed assets are company’s tangible assets that are relatively durable and used to run operations and generate income. Thus, they are not used to be consumed or sold, but to produce goods or services.

Due to the long-term use, the value of fixed assets decreases as they age. Some examples of depreciable fixed assets are buildings, machinery, and office equipment. However, land is not one of them, because it has an unlimited useful life and it increases in value over time.

In short, depreciation is the allocation of fixed asset acquisition costs that have a decrease in value. Thus, to find out what factors affect the depreciation of fixed assets and how to calculate them, see the explanation below.

The Causes of Depreciation

In general, there are two main causes of depreciation:

Physical Factor

The value of company’s assets can shrink due to overuse, aging, and damage.

Functional Factor

The cause of asset depreciation can also occur by the inability of assets to meet production needs, so there needs to be a change with new ones.

Factors That Affect the Depreciation Expenses

Acquisition Cost

This is the most influential factor on the depreciation expense. In addition, the acquisition cost refers to the total cost of buying an asset. Thus, it becomes the basis for calculating the depreciation that should be allocated per accounting period.

The acquisition cost includes shipping, sales and customs duty, as well as site preparation, installation and testing fees. In addition, With regard to manufacturing or production equipment, any costs related to bringing the equipment to an operational state may also be included in the acquisition cost. This includes the cost of shipping & receiving, general installation, mounting and calibration.

Salvage Value

The salvage value is the amount for which the asset can be sold at the end of its useful life. To determine the total amount depreciated, the salvage value must be subtracted from its initial cost.

For example, company A buys an asset worths 100,000,000 and they estimate that the salvage value will be 20,000,000 in five years. That means, they will depreciate 80,000,000 of the total cost of the asset and may expect to sell it for 20,000,000.

Economic Life

The economic life of an asset is the expected period of time as long as the asset remains useful to the owner. It can differ from its actual age. It is important for business owners to estimate the economic life of their assets, so they can determine when the right time to invest in or allocate funds for new assets.

How to Calculate Depreciation on Fixed Assets

There are several methods that you can implement to calculate depreciation on your  fixed assets. Here are the five most commonly used methods:

Straight-Line Depreciation Method

According to the straight line method, the depreciation value of a fixed asset will always be stable until the end of its economic life.

For example, if you buy a production machine for 50,000,000, the depreciable amount is 5,000,000, and the estimated economic life is 5 years, then the calculation is as follows:

Depreciation expense = (50,000,000 – 5,000,000)/5

Depreciation expense = 9

Double Declining Balance Method

The double-declining balance method is a form of intentional depreciation of a fast-speeding company in which most depreciation associated with an asset remains in place for the first few years of its economic life.

To calculate depreciation with this method, double the book value of the asset at the beginning of the fiscal year with a multiple of the straight-line depreciation rate. The formula is as follows:


Sum of the Years’ Digits Depreciation

Sum of the years’ digits depreciation is an accelerated form of depreciation based on the assumption that the asset productivity decreases over time.

This method seeks to impose higher depreciation cost in the early years of an asset’s economic life, because it is most productive in the early years of their use. The formula is as follows:

Service Unit Method

This method is especially useful for depreciating company’s vehicles. This method takes into account the life span of an asset to calculate depreciation. With this method, depreciation is calculated by dividing the total net cost of the asset by its estimated useful life. For example, in the case of a car, its useful life is its effective mileage.

Here is the formula:

Depreciation expense per year = reachable hours of work X depreciation rate per hour

Unit of Production Method

The unit of production method calculates depreciation on the actual use of an asset. According to this method, the depreciation expense of a fixed asset is determined based on the number of units of product produced.

The formula is as follows:

How to Instantly Calculate Depreciation on Your Fixed Assets

Depreciation of fixed assets must be calculated to account for the wear and tear on business assets over time. As depreciation is a non-cash expense, the amount must be estimated. Each year a certain amount of depreciation is written off and the book value of the asset is reduced.
