What is a Depreciation Calculator?
A Depreciation Calculator is an essential accounting tool that helps businesses and individuals calculate the decrease in value of assets over time. Depreciation is a fundamental accounting concept that allocates the cost of tangible assets over their useful lives, reflecting wear and tear, obsolescence, or age-related decline in value.
Our comprehensive depreciation calculator supports four major depreciation methods: Straight Line, Declining Balance, Sum of Years Digits, and MACRS (Modified Accelerated Cost Recovery System). Whether you're preparing financial statements, calculating tax deductions, planning capital expenditures, or managing business assets, this tool provides accurate calculations with detailed schedules and visualizations.

Depreciation Methods Explained
Straight Line Method
The simplest and most common depreciation method. Allocates equal depreciation expense each year over the asset's useful life.
Declining Balance Method
An accelerated depreciation method that applies a constant rate to the declining book value. Higher expenses in early years.
Sum of Years Digits
An accelerated method that allocates higher depreciation in early years based on a fraction of remaining useful life.
MACRS Method
The tax depreciation system used in the United States. Uses prescribed recovery periods and depreciation rates.
Frequently Asked Questions (FAQ)
What's the difference between straight line and accelerated depreciation?
Straight line depreciation allocates equal expense each year, resulting in a consistent annual charge. Accelerated depreciation methods (Declining Balance, Sum of Years Digits, MACRS) allocate higher expenses in the early years and lower expenses later. This matches the pattern where assets typically lose more value when they're new. Accelerated methods provide larger tax deductions in early years, which can improve cash flow, while straight line provides consistent expense recognition.
How do I choose the right depreciation method?
The choice depends on several factors:
- Tax requirements: MACRS is required for US tax purposes
- Asset type: Use accelerated methods for assets that lose value quickly (technology, vehicles)
- Financial reporting: Straight line is simplest and most commonly used for financial statements
- Cash flow needs: Accelerated methods provide larger early tax deductions
- Industry standards: Some industries have standard practices
What is salvage value and how is it estimated?
Salvage value (also called residual value or scrap value) is the estimated amount an asset will be worth at the end of its useful life. It represents what you could sell the asset for after it's fully depreciated. To estimate salvage value:
- Research similar used equipment sales
- Consider scrap metal value for machinery
- Account for disposal costs if negative
- Review industry standards
- Consider technological obsolescence
Can I change depreciation methods after starting?
Changing depreciation methods is generally allowed but has specific accounting implications:
- Accounting changes require justification and disclosure in financial statements
- Tax changes may require IRS approval (Form 3115 for automatic consent)
- Prospective application is most common - apply new method to remaining book value
- Restatement of prior periods is rarely permitted
- Materiality matters - small changes may not require formal change procedures
