What Is the Depreciation Calculator?
A depreciation calculator spreads an asset’s cost over its useful life.
How Does the Depreciation Calculator Work?
It applies the chosen method to give each year’s expense and the remaining book value.
Depreciation Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Straight-line spreads the depreciable amount evenly; the declining-balance method applies a fixed rate to the falling book value.
How to Use the Depreciation Calculator
- Choose the method and enter the cost, salvage value and useful life.
Step-by-Step Example Calculation
$10,000 asset, $1,000 salvage, 5 years
Input Values:
method:straightLine
cost:10000
salvage:1000
usefulLife:5
Worked Steps: Straight-line depreciation is $1,800 per year.
Understanding Your Result
The result is the annual depreciation plus a year-by-year book value table.
Factors That Affect the Result
- Cost, salvage value, useful life and method all affect depreciation.
When Should You Use This Calculator?
- Use it for accounting, tax planning and asset management.
Assumptions & Limitations
- Simplified methods only; tax rules such as MACRS may differ by country.
