See yearly depreciation and book value using the straight-line or declining balance method.
The method behind this calculator
Depreciation spreads an asset’s cost over its useful life. Enter the cost, salvage value and life, choose a method, and this calculator shows the yearly depreciation and remaining book value.
Straight-line is even each year; declining balance is faster early on.
Getting your answer
- Enter the asset cost and salvage value.
- Enter the useful life in years.
- Pick a method and read the schedule.
The formula
straight-line = (cost − salvage) ÷ life
declining (200%) = book value × 2 ÷ life each year
A worked example
On the values this calculator opens with, the year 1 depreciation is $3,600. Alongside it, Total depreciable comes out at $18,000. Change any field and every figure updates as you type.
FAQ
What’s the difference between the methods?
Straight-line depreciates the same amount each year; declining balance front-loads it, giving bigger deductions early.
What is book value?
The asset’s remaining value on the books — cost minus accumulated depreciation — which never drops below salvage.
Is this tax advice?
No — tax depreciation rules (like MACRS) differ by country. This is a general illustration.
