The document discusses the straight-line depreciation method. It allocates the same amount of depreciation expense each reporting period. To calculate straight-line depreciation, you need the cost, residual value, and useful life of the asset. The formula is Depreciation Expense = (Cost - Residual Value) / Useful Life. An example calculates depreciation expense of $2,400 per year for a van costing $16,000 over 4 years with a residual value of $6,400. The method can also be expressed as a percentage by dividing the annual depreciation expense by the original cost.

 Straight-line depreciation method
 Allocates the same amount of depreciation each reporting period
 Requires the following details to be ascertained:
Cost
The original cost of purchasing the asset plus all other costs incurred in
order to get the asset into a capacity and location to earn revenue
which will provide an economic benefit for the life of the asset
Residual
Value
The estimated amount the asset will be sold or traded-in for at the end
of its useful life (when it is “scrapped”)
Useful
Life
The estimated period of time the asset will be used for (in years)

 Example: a business purchased a van with the following details:
 Purchase price: $14,000
 Delivery fee: $2,000
 Estimated useful life: 4 years
 Estimated residual (scrap) value: $6,400

 For example, a delivery van
generating $25,000 of revenue each
period has the following details:
 Cost = $35,000
 Estimated useful life = 3 years
 Estimated residual value =
