When fixed assets are acquired for use in a business, they are usually useful only for a limited period.

The cost of these assets is allocated as an expense over the years they are used. This gradual conversion of an asset into an expense is known as depreciation.

In other words, depreciation is the allocation of the cost of a fixed asset to the period over which the benefit is obtained from the use of the asset.

Depreciation is calculated on the original cost. Importantly, depreciation should not be confused with an asset's market value. Any decrease in the market value of an asset cannot be regarded as depreciation.

Example: Depreciation

To clarify the concept of depreciation, let's consider an example.

A lorry costs $4,000 and will have a scrap value of $500 after continuous use of 10 years. This means that the cost of $3,500 ($4,000 - $500) is to be allocated as an expense over 10 years.

If the fixed installment method of depreciation is used, a cost of $350 is to be allocated as an expense at the end of each year. This is achieved through an adjusting entry.

If this allocation is not made, the income statement will reflect a higher income or lower loss.

In other words, the decline in the value of the asset by way of depreciation results directly from its use in the process of generating revenue.

In view of this, such loss should be charged against revenue.

Accounting Treatment of Depreciation

The amount of depreciation charged on various assets is considered a business expense.

At the same time, it is a reduction in the value of the particular asset upon which depreciation has been charged.

Therefore, depreciation has the following two effects on final accounts:

  • On the other hand, it is a reduction in the value of a particular asset; therefore, it is deducted from the associated asset's account in the balance sheet.

Adjusting Entry

The adjusting entry for a depreciation expense involves debiting depreciation expense and crediting accumulated depreciation. This is shown below.

Depreciation Expense Adjusting Entry

The depreciation expense appears on the income statement like any other expense. The accumulated depreciation is a contra asset account; it is shown as a deduction from the cost of the related asset in the balance sheet.

Both of these presentations are illustrated in the following example.

Example: Adjusting Entry

K & Co. purchased furniture costing $2,500 on 1 January 2016. The furniture's salvage value is zero, and it is decided to provide depreciation @ 10% p.a. on the original cost.

Required: Make an adjusting entry for depreciation expense on 31 December 2016. Also, how will the purchase be shown as a fixed asset on the balance sheet on 31 December 2016 and 31 December 2017?

Adjusting Entry for Depreciation

The above adjusting entry will also be made at the end of the next 9 years. After that period, the furniture will be fully depreciated ($250 × 10 years = $2,500).

Partial balance sheet as of 31 December 2016:

Balance in accumulated depreciation account at December 31, 2017: $250 + $250 = $500.
