Straight line depreciation
Straight line depreciation =
(Cost of asset – Salvage Value)
The straight line method calculates the depreciation expense for each asset and allocates the cost of each asset over the useful life.
Business owners, managers, and other interested parties use it to record the depreciation of assets whose book value steadily drops over time.
Note: expanded calculation
Spread the expenses of the asset evenly over its useful life after subtracting the asset’s salvage value.
M&M purchased a grinder machine for $450,000. It has an estimated salvage value of $90,000 and a useful life of 12 years. M&M calculates the annual straight-line depreciation.
Description of asset: Grinder Machine
Year (start): 20XX
Cost of asset: $450,000
Residual value (salvage value): $90,000
Useful Life: 12 years
Depreciation Rate: 8.33%
Depreciable Cost: $360,000
SEE: Depreciation Schedule - Straight Line Method
Depreciation Rate = 100% / useful life
Depreciation Rate = 100% /12 years = 8.33%
Depreciable Cost = cost of asset – residual value
Depreciable Cost = $450,000 – $90,000 = 360,000
Depreciation Expense = Depreciation Rate x Depreciable Cost
Depreciation Expense = 8.33% x 360,000 = $30,000
Accumulated Depreciation = Depreciation Expense + Accumulated Depreciation
Accumulated Depreciation (year 2) =$30,000 + $30,000 = $60,000 in year 2
Closing Book Value = Opening Book Value – Depreciation Expense
Closing Book Value = $450,000 – $30,000 = $420,000
This method is used to calculate depreciation on machinery that you expect to use until you scrap it.
