This depreciation calculator estimates how quickly an asset loses value over time. It supports multiple depreciation methods and generates a detailed schedule, including charts comparing book value and depreciation expense. It is ideal for simplifying accounting, tax calculations, and asset management.
Depreciation is the reduction in an asset's value over time due to wear and tear (e.g., machinery usage) or obsolescence (e.g., technology becoming outdated). In accounting, it allows spreading the asset’s cost over its useful life, helping assess its contribution to revenue and the company’s financial health.
Depreciation can be calculated using different methods depending on the asset type and how its value declines.
This is the simplest and most widely used method. Depreciation expense is the same every year and accounts for the asset's salvage value (the estimated value at the end of its useful life).
Depreciation Per Year = Asset Cost - Salvage Value / Useful Life
Steps:
An accelerated depreciation method that applies a fixed rate to the asset's decreasing book value each year. It results in higher depreciation in the early years.
Depreciation Per Year = Book Value × Depreciation Rate
Another accelerated method. Depreciation is higher in the early years and decreases over time. The depreciable amount is allocated according to a fraction based on the sum of years’ digits.
1st Year Factor = n / (1 + 2 + … + n)
2nd Year Factor = (n-1) / (1 + 2 + … + n)
…
Last Year Factor = 1 / (1 + 2 + … + n)
Steps:
Depreciation is based on asset usage. Ideal for machinery, vehicles, or other assets where wear depends on activity.
Depreciation Per Unit = (Cost − Salvage Value) / Total Expected Units
Depreciation Expense = Units Produced × Depreciation Per Unit
Our online depreciation calculator allows quick computation of all these methods for your assets.
Straight-line depreciation is the most widely used method due to its simplicity and consistent annual expense.
A lower depreciation percentage indicates the asset retains its value longer. Ideal rates vary by asset type and lifespan.
Depreciation helps businesses spread the cost of assets over their useful life. Benefits include:
Accumulated depreciation is the total depreciation recorded for an asset over time.
Formula: Accumulated Depreciation (Current Year) = Previous Year’s Total + Current Year Expense
