True Cost of Car Ownership Calculator
Calculate every cost of owning a car — loan payment, fuel, insurance, maintenance, tires, registration, parking, and depreciation. See the real annual and lifetime cost before you buy.
Most people only think about the monthly payment. This calculator shows what owning a car actually costs.

What is total cost of ownership?
Total cost of ownership (TCO) captures every significant expense associated with owning a vehicle over a period of time. Most buyers focus on the monthly payment — but that represents only a fraction of what a car actually costs.
The major cost categories are: financing (loan payments and interest), depreciation (value lost as the vehicle ages), fuel, insurance, maintenance and repairs, tires, registration and taxes, and parking and tolls. Together these often add up to $8,000–$15,000 per year for a typical vehicle — far more than the payment alone suggests.
Depreciation deserves special attention: it is typically the single largest cost of owning a new vehicle in the first few years, often exceeding the combined cost of fuel and insurance. A $35,000 car that depreciates 20% in year one loses $7,000 in value — an invisible cost most owners never account for.
The cost per mile figure is particularly useful for comparing vehicles: a car that costs $0.45/mile vs. $0.65/mile represents a $2,400 annual difference at 12,000 miles/year.
lightbulb Example: $32,000 Sedan
A $32,000 vehicle financed at 6.5% over 60 months with $2,000 down, driven 12,000 miles/year:
| Cost Category | Annual | 5-Year |
|---|---|---|
| Loan payment | $7,200 | $36,000 |
| Depreciation (avg) | $3,800 | $19,000 |
| Insurance | $1,400 | $7,000 |
| Fuel (30 MPG, $3.50) | $1,400 | $7,000 |
| Maintenance | $1,100 | $5,500 |
| Tires, reg, parking | $800 | $4,000 |
| Total | ~$15,700 | ~$78,500 |
Note: loan payments include principal repayment which builds equity, so the net economic cost is lower — but cash flow impact is what matters for budgeting.
TCO FAQs
Why is depreciation included if I don't sell the car?
Depreciation represents real economic value lost, whether or not you sell. If you buy a car for $35,000 and it's worth $20,000 in three years, you've "spent" $15,000 in lost value regardless of whether you sell. Including depreciation gives you the true economic cost of ownership, not just cash outlays.
How does the 20/4/10 rule apply here?
The 20/4/10 rule suggests putting 20% down, financing for no more than 4 years, and keeping total vehicle costs under 10% of gross monthly income. This calculator makes it easy to check: divide the annual cost by 12 and compare to 10% of your monthly income.
What's a typical cost per mile?
AAA estimates the average new vehicle costs $0.70–$0.85 per mile to own and operate when all costs are included. Fuel-efficient economy cars run closer to $0.45–$0.55/mile; trucks and SUVs often exceed $0.80–$1.00/mile. Knowing your cost per mile makes it easy to compare vehicles and evaluate whether driving vs. alternatives (rideshare, transit) makes financial sense.
Does the total include the vehicle's resale value?
The depreciation figure represents value lost, which implicitly accounts for resale value. The total cost shown is the net economic cost — purchase price minus estimated future value, plus all operating costs over the period.
TCO terminology
Total Cost of Ownership (TCO)
The complete economic cost of owning an asset over a defined period — purchase price (minus residual value) plus all operating and carrying costs. The standard metric for comparing vehicles with different purchase prices and operating profiles.
Cost Per Mile
Total annual cost divided by annual miles driven. A compact sedan might cost $0.50/mile; a large SUV $0.85/mile. Useful for comparing vehicles and evaluating the economics of high vs. low mileage driving patterns.
Fixed Costs
Costs that don't change with how much you drive: loan payment, insurance, registration, and depreciation (approximately). These are incurred whether you drive 1,000 miles or 20,000 miles per year.
Variable Costs
Costs that scale with mileage: fuel, tires, and a portion of maintenance. High-mileage drivers see these costs compound significantly over a vehicle's life.
Opportunity Cost
The return you forgo on the capital tied up in a vehicle. A $30,000 car purchased outright "costs" an additional $1,500–$2,400/year in foregone investment returns at 5–8% — rarely included in standard TCO calculations, but worth considering for large purchases.
