Business Vehicle Depreciation Calculator
Tax Disclaimer: This calculator provides estimates only. Consult with a qualified tax professional for specific advice. Tax laws and limits change annually.
Purchasing a vehicle for business use can unlock significant tax deductions—but only if depreciation is calculated correctly. With multiple IRS-approved methods such as Section 179, Bonus Depreciation, MACRS, and Straight-Line, choosing the wrong option may result in thousands of dollars lost in potential tax savings.
The Business Vehicle Depreciation Calculator helps business owners, freelancers, and self-employed professionals quickly estimate depreciation deductions, compare methods, and determine the most tax-efficient approach for their vehicle.
What Is a Business Vehicle Depreciation Calculator?
A Business Vehicle Depreciation Calculator estimates how much of a vehicle’s cost can be deducted for business use over time. It factors in:
- Vehicle purchase price
- Business-use percentage
- Vehicle classification (heavy, SUV, standard, luxury)
- IRS depreciation method
- Annual business mileage
- Standard mileage deduction rate
The calculator then compares actual expense depreciation against the standard mileage method to recommend the option that provides the maximum tax deduction.
Why Vehicle Depreciation Matters for Businesses
Vehicles used for business purposes are considered depreciable assets. Instead of deducting the full purchase price in one year, the IRS allows businesses to deduct portions of the cost over time—unless special deductions apply.
Correct depreciation planning helps you:
- Reduce taxable income
- Improve cash flow
- Make informed vehicle purchase decisions
- Stay compliant with IRS regulations
This calculator simplifies that planning process.
Depreciation Methods Covered by the Calculator
Section 179 Deduction

Best for:

Bonus Depreciation (100%)
