🧮 Car Cost to Own Formula
While the calculator does complex math in the background, here’s a simplified version:
pgsqlCopyEditTotal Cost to Own = Depreciation + Fuel + Insurance + Maintenance + Repairs + Taxes/Fees + Loan Interest Monthly Cost = Total Cost to Own ÷ Ownership Period (in months)
Cost per Mile = Total Cost to Own ÷ Total Miles Driven

🚘 Compare Cars Side by Side
A powerful feature of this calculator is vehicle comparison. You can enter data for two or more cars and view their ownership costs side by side. This helps determine whether a hybrid saves more than a gas-powered car, or whether a new car is worth the cost over a used model.
📊 Hidden Costs Most Buyers Overlook
- Depreciation
The biggest cost, especially for new cars — up to 20–30% in the first year. - Insurance Fluctuations
Sports cars and newer models cost more to insure. - Fuel Efficiency Gap
Real-world fuel use often differs from advertised MPG. - Maintenance Spikes
Older cars require more frequent and expensive upkeep. - Loan Interest
A higher APR increases total cost significantly.
💡 Tips to Lower Total Ownership Cost
- Buy a car with high resale value
- Choose a fuel-efficient or electric vehicle
- Maintain your vehicle regularly
- Shop around for cheaper insurance
- Opt for a shorter loan term
- Avoid excessive mileage that increases depreciation
