Depreciation Calculator
Track asset depreciation with side-by-side straight-line and double-declining calculations to plan financial statements or tax deductions.
Compare straight-line and declining-balance depreciation over an asset’s life.
| Year | Straight expense | Straight book value | Declining expense | Declining book value |
|---|---|---|---|---|
| 1 | $3,200.00 | $14,800.00 | $7,200.00 | $10,800.00 |
| 2 | $3,200.00 | $11,600.00 | $4,320.00 | $6,480.00 |
| 3 | $3,200.00 | $8,400.00 | $2,592.00 | $3,888.00 |
| 4 | $3,200.00 | $5,200.00 | $1,555.20 | $2,332.80 |
| 5 | $3,200.00 | $2,000.00 | $332.80 | $2,000.00 |
Depreciation methods
Straight-line expense = (Cost − Salvage) ÷ Useful life. Double-declining rate = 2 ÷ Useful life applied to the beginning book value each year.
How to use
- Enter the asset cost, expected salvage value, and useful life in years.
- Adjust the declining-balance multiplier if you want a rate other than double.
- Review the per-year depreciation tables and cumulative book value.
Example
Input: Cost = $18,000, Salvage = $2,000, Life = 5 years
Output: Straight-line expense = $3,200/year, First-year double-declining ≈ $7,200
FAQ & notes
Can I switch to 150% declining balance?
Yes. Change the declining multiplier from 2.0 to 1.5 to mirror the 150% method.
Does the schedule stop at salvage value?
The calculator caps book value at the salvage amount automatically so depreciation never overshoots.
