Definition
Straight-Line Depreciation is a method used to depreciate an asset whereby an equal amount of the depreciation expense is allocated in each accounting period over the asset’s useful life. This contrasts with methods that may accelerate or decelerate depreciation. Straight-line depreciation is commonly used for both tax and accounting purposes to systematically reduce the book value of real estate properties.
Examples
Example 1:
A property has a depreciable basis of $400,000 with a useful life of 40 years and no salvage value. Using the straight-line depreciation method, the property’s book value decreases by $10,000 each year. Therefore, the annual tax deduction for depreciation is $10,000.

Example 2:
Consider an office building purchased for $1,000,000 with an expected useful life of 50 years and an estimated salvage value of $50,000. The straight-line depreciation expense per year would be calculated as follows:
\[ \text{Annual Depreciation} = \frac{\text{Cost - Salvage Value}}{\text{Useful Life}} \]
\[ \text{Annual Depreciation} = \frac{$1,000,000 - $50,000}{50} = $19,000 \text{ per year} \]
Frequently Asked Questions
Q1: What are the benefits of using straight-line depreciation?
- A1: Straight-line depreciation is simple, offers consistent annual depreciation expense, and provides clear financial projections. It is often preferred for financial reporting due to its simplicity.
Q2: Can straight-line depreciation be used for both residential and commercial properties?
- A2: Yes, straight-line depreciation can be applied to both residential and commercial properties under tax regulations, though the useful life assigned to each type can differ.
Q3: How is salvage value considered in straight-line depreciation?
- A3: Salvage value is subtracted from the initial cost of the asset before dividing by the useful life to determine the annual depreciation expense.
Q4: How does straight-line depreciation affect taxes?
- A4: Straight-line depreciation provides a steady annual tax deduction, lowering taxable income and thus tax liabilities over the asset’s useful life.
Q5: Is it possible to change depreciation methods once a property is being depreciated?
- A5: Typically, changes in depreciation methods require approval from tax authorities and amendments to prior financial statements, and may have regulatory limitations.
Depreciation (Accounting): The systematic allocation of the cost of an asset over its useful life. Useful Life: The estimated time period that an asset is expected to be used before it is either disposed of or fully depreciated. Salvage Value: The estimated value that an asset will have at the end of its useful life. Book Value: The value of an asset as recorded on the company’s balance sheet, which originally equals cost minus accumulated depreciation. Accelerated Depreciation: A method which allocates a higher depreciation expense in the asset’s earlier years.
