What is Depreciation?
Depreciation is the gradual reduction in the value of a tangible asset over time due to wear and tear, usage, or obsolescence. Businesses use depreciation to spread the cost of an asset over its useful life, reflecting its declining value in financial statements.
Why is Depreciation Important?
- Accurate Financial Reporting: Depreciation ensures expenses are matched with the revenue they generate, providing a true picture of profitability.
- Tax Deductions: Many governments allow businesses to claim depreciation as a tax-deductible expense.
- Asset Management: Depreciation helps track the value and lifespan of assets.
Stat: According to the IRS, depreciation deductions accounted for over $1 trillion in business expenses in recent tax years, highlighting its significance for businesses of all sizes.
Common Methods for Calculating Depreciation
There are several methods for calculating depreciation, each suited to different types of assets and business needs. Here are the most commonly used methods:
1. Straight-Line Depreciation
The most straightforward method, straight-line depreciation allocates an equal amount of depreciation expense over the asset’s useful life.
Formula:
Example: A company purchases a piece of equipment for $10,000, with a salvage value of $2,000 and a useful life of 5 years.
The company records $1,600 as a depreciation expense annually.
2. Declining Balance Method
This accelerated method applies a fixed percentage to the asset’s book value, resulting in higher depreciation expenses in the early years.
Formula:
Example: An asset costs $10,000 with a depreciation rate of 20%.
- Year 1: $10,000 × 20% = $2,000
- Year 2: $8,000 × 20% = $1,600
This method is ideal for assets that lose value quickly, such as vehicles or technology.
3. Units of Production Method
This method bases depreciation on the asset’s usage or output rather than time.
Formula:
Example: A machine costs $15,000, with a salvage value of $3,000 and an expected output of 100,000 units. If the machine produces 20,000 units in a year:
4. Sum-of-the-Years’ Digits Method
An accelerated depreciation method that allocates higher depreciation expenses in the earlier years.
Formula:
Example: For an asset with a 5-year life, the sum of the years is:
In the first year, the depreciation expense would be:

Example Journal Entry:
| Account | Debit | Credit |
|---|---|---|
| Depreciation Expense | $1,600 | |

Practical Examples of Depreciation
Example 1: Office Furniture
- Cost: $5,000
- Salvage Value: $500
- Useful Life: 10 years
Using straight-line depreciation:
Example 2: Company Vehicle
- Cost: $30,000
- Salvage Value: $5,000
- Useful Life: 5 years
Using declining balance at 20%:
- Year 1: $30,000 × 20% = $6,000
- Year 2: $24,000 × 20% = $4,800
