About Straight Line Depreciation

The straight-line method is the simplest and most commonly used way to calculate depreciation. It allocates an equal amount of depreciation each year over the asset’s useful life.

Formula: (Cost – Salvage Value) / Useful Life

Understanding Depreciation Methods

Why Calculate Depreciation?

Depreciation is a fundamental accounting concept that helps businesses:

  • Accurately report asset values on financial statements
  • Allocate asset costs over their useful lives
  • Reduce taxable income through depreciation expenses
  • Plan for asset replacement and capital expenditures
  • Comply with accounting standards and tax regulations

Depreciation Methods Explained

Straight Line Depreciation: The simplest method that allocates equal depreciation expense each year.

Declining Balance Depreciation: An accelerated method that applies a constant depreciation rate to the reducing book value each year.

Sum of the Year’s Digits Depreciation: Another accelerated method that uses a fraction based on the sum of the years’ digits.

When to Use Each Method

  • Straight Line: Best for assets that lose value evenly over time (e.g., buildings, furniture)
  • Declining Balance: Ideal for assets that lose more value in early years (e.g., vehicles, technology)
  • Sum of the Year’s Digits: Suitable for tax purposes when you want to front-load depreciation expenses

Factors Affecting Depreciation

  • Asset Cost: The original purchase price including taxes, delivery, and installation
  • Salvage Value: Estimated residual value at the end of the asset’s useful life
  • Useful Life: The period over which the asset is expected to be productive
  • Depreciation Method: The accounting approach used to allocate costs
  • Depreciation Rate: The percentage at which the asset depreciates each year
