Depreciation Calculators
Straight-line, declining balance, double-declining and sum-of-years-digits depreciation schedules.
Depreciation
Straight-Line Depreciation Calculator
Equal annual depreciation over an asset’s useful life: (cost − salvage) ÷ years, with the full schedule.
Annual = (cost − salvage) / useful life
Also called straight line depreciation · sl depreciation
Depreciation
Declining Balance Calculator
Declining balance depreciation at any factor (e.g. 150%), switching to straight-line when advantageous.
Dep = book value × factor / life
Also called declining balance depreciation · 150% declining balance
Depreciation
Double Declining Balance Calculator
Double declining balance (DDB) depreciation — accelerated write-off at twice the straight-line rate.
Dep = 2 × book value / life
Also called ddb depreciation · double declining
Depreciation
Sum-of-the-Years Digits Calculator
Sum-of-the-years’-digits (SYD) accelerated depreciation schedule for any asset.
Dep = (cost − salvage) × remaining life /…
Also called syd depreciation · sum of years digits
Depreciation
Car Depreciation Calculator
Estimate your car’s value after each year of ownership and the total depreciation cost per year and per mile.
Value = price × (1 − d₁)(1 − d)ⁿ⁻¹
Also called vehicle depreciation · car value calculator
Depreciation
Book Value Calculator
Book value of an asset after N years of straight-line depreciation, or a company’s book value per share.
Book value = cost − accumulated depreciat…
Also called net book value · carrying value
Depreciation
Salvage Value Calculator
Estimate an asset’s salvage (residual) value from its cost, a declining depreciation rate and years of use.
S = cost × (1 − rate)ⁿ
Also called residual value · scrap value
Depreciation
Depreciation Rate Calculator
Annual depreciation rate from cost, salvage value and useful life — straight-line and equivalent declining rate.
SL rate = 1 / life
Also called rate of depreciation · annual depreciation percentage
Key depreciation formulas
| Depreciation | SL: (cost − salvage) / life · DDB: 2 × book value / life |
|---|---|
| Straight-Line Depreciation | Annual = (cost − salvage) / useful life |
| Declining Balance | Dep = book value × factor / life |
| Double Declining Balance | Dep = 2 × book value / life |
| Sum-of-the-Years Digits | Dep = (cost − salvage) × remaining life / SYD |
| Car Depreciation | Value = price × (1 − d₁)(1 − d)ⁿ⁻¹ |
| Book Value | Book value = cost − accumulated depreciation |
| Salvage Value | S = cost × (1 − rate)ⁿ |
| Depreciation Rate | SL rate = 1 / life · Declining = 1 − (salvage/cost)^(1/life) |
