Free Car Cost Calculator - Calculate Total Ownership Costs
Calculate total cost of car ownership including financing, insurance, fuel, and maintenance.
Formula & Methodology
The true cost of owning a vehicle extends far beyond the sticker price. This calculator combines fixed financing costs with variable operating expenses to provide a comprehensive view of your monthly, yearly, and lifetime automotive expenditures.
- Monthly Finance Cost = P × [r(1+r)^n] / [(1+r)^n - 1]
- Monthly Fuel Cost = (Miles per Day × 30.4 / MPG) × Gas Price
- Monthly Operating Cost = Insurance + Fuel + Maintenance + (Taxes/12) + Parking
- Total Ownership Cost = (Monthly Finance + Monthly Operating) × 12 × Ownership Years
Worked Example
Using the Car Ownership Cost Calculator: apply the formula above to your input values. For instance, Monthly Finance Cost = P × [r(1+r)^n] / [(1+r)^n - 1], then Monthly Fuel Cost = (Miles per Day × 30.4 / MPG) × Gas Price. The tool performs each step instantly and shows the result.
