The assets that a business can allocate over a period can be tangible or intangible.

Allocation of the cost of intangible business assets is known as amortization. In this blog post, we will delve more into the topic.

Amortization Expenses: An Overview

Amortization expenses allocate the cost of intangible assets over the life of the asset. Intangible assets include assets that are not in physical form. Examples of intangible assets that can be amortized by outsourced bookkeeping service providers include patents and trademarks.

An important thing to remember regarding amortization costs is that only intangible assets with a limited life can be amortized. Intangible assets such as goodwill that have an indefinite life cannot be amortized. Moreover, the IRS sets a limit on the expense that can be amortized in a year. The limit is known as capital cost allowances.

Amortization expenses are recorded in the income statement of the company. In addition, the expenses reduce the book value of the amortized asset by the same amount on the balance sheet.

Examples of Amortization Expenses

Accountants amortize the intangible asset until the end of its useful life. The amount is recorded in the financial statement until the cost of the asset is fully amortized over its life.

An example will help in understanding the concept of amortization expense.

Suppose that a company owns a patent valued at $250,000 that expires in 10 years. Accountants can calculate the amortization expenses using two methods. To calculate the amortization expense, the patent value is divided by the patent life as shown below.

$250,000 / 10 = $25,000

The following table shows how the amortization expense reduces the value of the intangible asset over its life.

YearPatent Book Value ($) – AAmortization Expenses ($) – BAmortized Value ($) – A-B
1         250,000         25,000         225,000
2         225,000         25,000         200,000
3         200,000         25,000         175,000
4         175,000         25,000         150,000
5         150,000         25,000         125,000
6         125,000         25,000         100,000
7         100,000         25,000           75,000
8           75,000         25,000           50,000
9           50,000         25,000           25,000
10           25,000         25,000                 0

You can see in the above table that the amortization expense remains the same each period. This expense will be recorded in the income statement of the company when the financial statement is prepared.

You can also see that the book value of the intangible asset is reduced each year. The amortized value of the asset becomes zero at the end of the useful life. In the above table, you can see that the amortized value that is calculated by subtracting the net book value during a period with the amortization expense is zero at the tenth year when the patent ends.

Difference Between Amortization, Depreciation, and Depletion

The three different methods for calculating the asset value include amortization, depreciation, and depletion. The main difference between the two methods depends on the type of asset that is expensed over a period.

Amortization expenses involve the allocation of the cost of intangible assets – patents, trademarks, franchise agreements, and copyrights. The expense is calculated using the single line balance method. It reduces the net profit in the income statement and the value of the amortized asset on the balance sheet.

In contrast, depreciation expenses involve the allocation of the cost of the tangible assets – office furniture, computer equipment, vehicles, and machinery. The expense is calculated using different methods including the single line balance method, declining method, the sum of years’ digit method, and modified accelerated cost recovery system (MACRS).

Depletion is similar to depreciation and amortization which is valid for natural resources. Accountants calculate depletion expenses for assets such as oil, timber, agricultural products, and minerals.

Assets that are amortized or depleted don’t have any salvage value. Contrarily, assets that are depreciated have a salvage value that is accounted for when calculating the depreciation expenses.

The term amortization can also be used for the loan but in a different context. Accountants create an amortization schedule that shows the payment of loans such as mortgage loans over a period.

How Amortization Expenses are Recorded by Outsourced Bookkeepers?

Amortization expenses are recorded through debit and credit entries in the journal. The amortization expense is debited and a contra asset accumulated depreciation is credited. The following journal entry is made when recording amortization expenses during a period.

Amortization Expenses (Debit)

Accumulated Amortization Expenses (Credit)

Let’s suppose that the amortization expense of a patent value is $30,000. The amortization expense can be recorded by making the following entry in the journal.

Amortization Expenses (Debit) $30,000

Accumulated Amortization Expenses (Credit) $30,000

The amortization expense of $30,000 will be entered into the income statement. It will reduce the net profit reported in the financial statement. In addition, amortization expense will reduce the book value of the asset by $30,000.

The following shows the excerpts from the income statement and balance sheet of a fictional company that shows how the amortization expenses will be recorded in the financial statements.

Income Statement
Net Revenue$180,000
Less Cost of Goods Sold$50,000
Gross Profit$130,000
Less Expenses 
Utility cost$12,000
Legal expenses$24,000
Outsourced Bookkeeping Services$50,000
Amortization Expenses$30,000
Net Expenses$116,000
Net Profit$14,000

Conclusion

Amortization, depreciation, and depletion are all non-cash expenses. The expenses are not recorded in the cash flow statement. Some accountants use the terms amortization and depreciation interchangeably, which is wrong.

The key difference between the three is the type of asset that is expensed over its useful life. The allocation of intangible assets is known as amortization. In contrast, the allocation of tangible assets is known as depreciation. The act of allocating the value of natural resources is called depletion.

Frequently Asked Questions

What is amortization in accounting?

Amortization is the process of spreading the cost of an intangible asset over its useful life. Similar to depreciation for physical assets, amortization reduces the book value of intangible assets like patents, trademarks, software licenses, and goodwill over time.

How is amortization calculated?

The most common method is straight-line amortization: divide the asset cost by its useful life. For example, a $50,000 patent with a 10-year useful life has annual amortization of $5,000. This expense is recorded each year on the income statement and reduces the asset value on the balance sheet.

What is the difference between amortization and depreciation?

Amortization applies to intangible assets (patents, software, goodwill) while depreciation applies to tangible assets (equipment, vehicles, buildings). Both spread costs over time, but depreciation offers multiple calculation methods while amortization typically uses the straight-line method.

Is amortization a tax-deductible expense?

Yes. Amortization of qualifying intangible assets is tax-deductible. Section 197 intangibles acquired in a business purchase are amortized over 15 years for tax purposes. Your bookkeeper and CPA can determine which intangible assets qualify for amortization deductions.

How does amortization affect my financial statements?

Amortization appears as an expense on the income statement, reducing taxable income. On the balance sheet, it reduces the carrying value of intangible assets. On the cash flow statement, amortization is added back since it is a non-cash expense.
