Getting to Know Depreciation: The Concept You Need to Understand for Managing Business Assets

In the world of accounting and finance, depreciation is a concept that businesses need to understand thoroughly. It is not just a complicated financial term, but a tool that helps you track the true value of a company’s assets accurately.

What is Depreciation? Understanding from the Basics

Depreciation refers to the process by which the value of an asset decreases over time. A simple example is when a company purchases a new computer; its value will differ from year one to year five.

Accountants use depreciation to:

• Record the decline in asset value over its useful life
• Spread the cost of expensive assets over many years instead of paying all at once in the first year
• Create a realistic picture of the company’s financial condition

In the income statement, depreciation is included in the calculation of EBIT(Earnings Before Interest and Taxes), which affects how investors compare different companies.

Why is Depreciation Important for Business Management?

Imagine Company A buys machinery for 500,000 THB. If it records all expenses in the first year, that year’s profit will look very poor. But in reality, this machinery can be used for the next 10 years.

This is where depreciation comes in—it allocates the expense gradually each year, making the company’s profit picture more realistic.

When comparing two companies—one with many fixed assets(such as factories and machinery)and another with fewer assets—different depreciation rates can cause net profit figures to vary significantly.

Which Assets Can Be Depreciated?

Not all assets are depreciable. Assets must meet basic criteria:

Assets that can be depreciated:

• Vehicles and automobiles
• Buildings and structures
• Machinery and equipment
• Computer systems and electronic devices
• Furniture and fixtures
• Some intangible assets like patents and copyrights

Assets that are not depreciable:

• Land(value does not decrease)
• Collectibles such as art and coins
• Investments like stocks and bonds
• Personal property
• Assets with a useful life of less than 1 year

The Four Main Methods of Calculating Depreciation

1. Straight-Line Method (The simplest and most commonly used method. You just divide the asset’s cost evenly over its useful life.

Example: A company buys a car for 200,000 THB with an expected lifespan of 5 years. Annual depreciation = 200,000 ÷ 5 = 40,000 THB/year

Advantages: Easy to understand and implement, with minimal errors. Disadvantages: Does not account for assets losing value faster in the early years or increased maintenance costs as they age.

) 2. Double-Declining Balance ###This method accelerates depreciation, taking more in the early years and less later. Suitable for assets that lose value quickly, like vehicles or tech equipment.

Advantages: Helps offset rising maintenance costs and maximizes early tax deductions. Disadvantages: More complex; businesses might not benefit from tax deductions if they incur losses.

( 3. Declining Balance Method )Another accelerated depreciation method, calculated as twice the straight-line rate, but based on the remaining book value rather than original cost.

Expenses are higher in the initial years and decrease over time.

4. Units of Production Method (Used when depreciation depends on actual usage rather than time, such as hours operated or units produced.

Example: If a machine produces 100,000 units over its life, and this month it produces 10,000 units, depreciation is 10% of the cost.

Advantages: High accuracy, reflects actual usage. Disadvantages: Difficult to track and calculate; not suitable for all companies.

What is Amortization)?

While depreciation applies to tangible assets###that can be bought and touched(, amortization is used for intangible assets like copyrights, patents, and trademarks.

Additionally, amortization also refers to the process of repaying a loan in equal installments, each consisting of interest and principal.

)Example of amortization:

Intangible assets: A company purchases software rights for 50,000 THB with a useful life of 5 years. Annual amortization = 50,000 ÷ 5 = 10,000 THB/year

Loans: You borrow 100,000 THB with the intention to repay over 5 years with interest. Monthly payments include both principal and interest until fully paid.

Key Differences Between Depreciation and Amortization

EBIT and EBITDA: Why Are They Important in Relation to Depreciation?

EBIT )Earnings Before Interest and Taxes( = profit before interest and taxes

• Includes depreciation and amortization expenses

EBITDA )Earnings Before Interest, Taxes, Depreciation, and Amortization(

• Excludes depreciation and amortization
• Shows the company’s true operating profit

Investors use EBITDA to see the company’s real profit-generating ability, unaffected by different accounting policies, especially when comparing companies with different debt structures or asset bases.

Summary: Why is Depreciation Important in the Financial World?

Depreciation may seem like just a complex accounting concept, but it plays a vital role in:

• Reflecting the true value of assets
• Allowing proper tax deductions
• Providing investors with an accurate picture of profit and financial health
• Enabling fair comparison between companies

Understanding how to calculate and apply depreciation correctly will help you analyze a business’s financial position deeply, whether you are a business owner, accountant, or investor making informed decisions.
