Understanding Personal Use of Vehicle Calculations
Personal use of vehicle calculations help determine the business portion of vehicle expenses for tax reporting. This calculator uses the Standard Mileage Method approved by the IRS, considering multiple cost factors including fuel consumption, maintenance expenses, and vehicle depreciation.
Calculation Formula
Business Use Percentage = (Business Miles / Total Miles) × 100
Total Deductible Costs = (Fuel Costs + Maintenance Costs + Depreciation) × Business Use Percentage
| Variable | Description | Unit | Typical Range |
|---|---|---|---|
| Total Miles | Annual mileage | Miles | 5,000-50,000 |
| Business Miles | Work-related driving | Miles | 1,000-25,000 |
| Fuel Cost | Gasoline price | $/gallon | $2.50-$5.00 |
| MPG | Fuel efficiency | Miles/gallon | 15-40 |
