📉 Depreciation Calculator
Calculate asset depreciation using multiple methods
đź’ˇ Tip: For tax purposes, consult your accountant to confirm allowable depreciation methods for your jurisdiction.
How to Use This Tool
Follow these steps to calculate asset depreciation for your business:
- Enter your asset’s total purchase cost, including any setup or delivery fees.
- Input the estimated salvage value (the amount you expect to sell the asset for at the end of its useful life).
- Select your preferred depreciation method from the dropdown menu.
- Fill in the method-specific fields that appear (e.g., useful life in years for straight-line, total units for units of production).
- Click the Calculate Depreciation button to view your results.
- Use the Reset button to clear all inputs and start a new calculation.
Formula and Logic
Each depreciation method uses a different formula to allocate asset cost over its useful life:
Straight-Line Depreciation
Annual Depreciation = (Asset Cost - Salvage Value) / Useful Life in Years. This spreads depreciation evenly across all years of the asset’s life.
Declining Balance Methods
Annual Depreciation = Current Book Value Ă— (1 / Useful Life Ă— Declining Balance Rate). This front-loads depreciation, with higher expenses in early years.
Sum-of-Years-Digits
Annual Depreciation = (Asset Cost - Salvage Value) Ă— (Remaining Useful Life / Sum of Years Digits). Sum of Years Digits = n(n+1)/2 where n is useful life in years.
Units of Production
Per Unit Depreciation = (Asset Cost - Salvage Value) / Total Estimated Units. Annual Depreciation = Per Unit Depreciation Ă— Current Year Units Produced.
Practical Notes
For small business owners, entrepreneurs, and e-commerce sellers, keep these context-specific tips in mind:
- Tax authorities (e.g., IRS in the US) have specific rules for which depreciation methods are allowable for different asset types. Always confirm with a tax professional before filing.
- E-commerce sellers should depreciate large equipment like 3D printers, packaging machinery, and delivery vehicles separately from smaller expenses.
- Traders and resellers can use depreciation to offset taxable income from asset sales, improving cash flow for reinvestment.
- Salvage value estimates should be conservative to avoid overstating asset value on financial statements.

Frequently Asked Questions
Can I use this calculator for tax purposes?
This tool provides estimates for planning purposes only. Tax depreciation rules vary by jurisdiction and asset type, so consult a certified accountant before including depreciation figures in official tax filings.
What’s the difference between straight-line and declining balance depreciation?
Straight-line spreads depreciation evenly over an asset’s life, while declining balance methods allocate higher depreciation expenses in early years, which can lower taxable income sooner for profitable businesses.
How do I calculate depreciation for e-commerce inventory storage equipment?
Storage shelves, forklifts, and climate control systems are all depreciable assets. Enter their purchase cost, estimated salvage value, and useful life (typically 5-10 years for heavy equipment) to calculate annual expenses.
Additional Guidance
For more accurate results, keep detailed records of all asset-related expenses including shipping, installation, and initial repairs. Update your depreciation calculations annually to reflect any changes in asset condition or useful life estimates. If you dispose of an asset before the end of its useful life, recalculate depreciation up to the disposal date for accurate financial reporting.
