About Depreciation

Depreciation is an accounting method used to allocate the cost of a tangible or physical asset over its useful life. Businesses use depreciation to expense an asset over time rather than in the period it was purchased.

Depreciation Methods
  • Straight-Line: The simplest method that evenly distributes the depreciable cost over the useful life.
  • Double Declining Balance: An accelerated method that applies a higher depreciation rate in the earlier years.
  • Sum of Years' Digits: Another accelerated method where depreciation is calculated by multiplying the depreciable cost by a fraction based on the asset's remaining life.
  • Units of Production: Bases depreciation on the asset's usage, output, or production rather than time.
  • MACRS (Modified Accelerated Cost Recovery System): The standard depreciation system for U.S. tax purposes.
Depreciation Formulas

Straight-Line Depreciation:

Annual Depreciation = (Cost - Salvage Value) / Useful Life

Double Declining Balance:

Rate = 2 / Useful Life
Annual Depreciation = Book Value ร— Rate

Sum of Years' Digits:

SYD = n(n+1)/2 where n = useful life
Annual Depreciation = (Remaining Life / SYD) ร— (Cost - Salvage Value)

Units of Production:

Depreciation Per Unit = (Cost - Salvage Value) / Estimated Total Units
Annual Depreciation = Units Produced in Year ร— Depreciation Per Unit
Key Definitions
  • Asset Cost: The purchase price plus all costs necessary to bring the asset to working condition.
  • Salvage Value: The estimated value of the asset at the end of its useful life.
  • Useful Life: The estimated period over which the asset will be used by the business.
  • Book Value: The asset's value as shown on the balance sheet (original cost minus accumulated depreciation).
  • Depreciable Base: Asset cost minus salvage value, representing the total amount to be depreciated.
