Calculation Formula

Depreciable Base = Asset Cost – Salvage Value
Depreciation per Unit = Depreciable Base / Useful Units
Depreciation for Period = Units Used × Depreciation per Unit

Example

You purchase a car for your business for $22,000 and expect it to have a life of 60,000 miles with a final salvage value of $2,000. If you drive 17,000 miles in a period:

Depreciable Base = $22,000 – $2,000 = $20,000
Depreciation per Mile = $20,000 / 60,000 Miles = $0.333/Mile
Depreciation for Period = 17,000 Miles × $0.333/Mile = $5,661.00

Depreciation Results

Depreciable Base: $0.00
Depreciation per Unit: $0.00
Depreciation for Period: $0.00
