Accelerate Your Depreciation: Double Declining Balance Calculator
Double Declining Balance Depreciation Calculator
Calculate the annual depreciation expense for an asset using the Double Declining Balance method, providing a year-by-year schedule.
Input Your Data
The initial cost of the asset.
The estimated residual value of the asset at the end of its useful life.
The estimated number of years the asset will be used.
Summary Results
Total Depreciable Amount:
$0.00
The portion of the asset's cost that will be depreciated.
Total Accumulated Depreciation:
$0.00
The total depreciation over the asset's useful life.
Book Value at End of Life:
$0.00
The asset's value remaining after all depreciation.

How It Works
- Enter the initial cost of the asset.
- Input the estimated salvage value (what the asset is worth at the end of its useful life).
- Provide the estimated useful life of the asset in years.
- Click "Calculate" to see the full depreciation schedule and summary results.
- The "Clear" button will reset all fields and the schedule.
Formula for Depreciation Rate: (1 / Useful Life) × 2
Formula for Annual Depreciation: (Beginning Book Value) × Depreciation Rate
Note: The depreciation amount is adjusted in later years to ensure the asset's book value does not fall below its salvage value.
How the double declining balance calculator works
Double declining balance is an accelerated depreciation method. It applies twice the straight-line rate to the asset’s opening book value each year, so the charge is highest at the start and falls over time. Depreciation stops once the book value reaches the residual value.
Depreciation = Rate × Opening book value
Worked example
An asset costs 10,000 and has a 5-year life, so the rate is 2 ÷ 5 = 40%.
| Year | Opening book value | Depreciation (40%) | Closing book value |
|---|---|---|---|
| 1 | 10,000 | 4,000 | 6,000 |
| 2 | 6,000 | 2,400 | 3,600 |
| 3 | 3,600 | 1,440 | 2,160 |
Frequently asked questions
Is the residual value deducted first?
No. The rate is applied to the opening book value, but the charge is limited so that the book value never falls below the residual value.
How does it differ from straight-line depreciation?
Straight-line charges the same each year. Double declining balance charges more in the early years and less later.
