Understanding the true Total Cost of Ownership (TCO) is crucial before buying a car. Use this calculator to estimate your vehicle’s cost over a 10-year period, covering initial purchase, depreciation, fuel, maintenance, and insurance.

10 Year Cost of Ownership Car Calculator Formula
$$ \text{TCO} = (P – R) + 10 \times (F + M + I) $$
Variables Explained
The TCO calculation relies on five primary variables, all measured in US Dollars ($), estimated over a 10-year horizon.
- Initial Purchase Price ($P$): The full cost of the vehicle when new, including taxes and fees.
- Estimated 10-Year Resale Value ($R$): The estimated market value of the vehicle after 10 years of use.
- Annual Fuel/Energy Cost ($F$): The total expected cost of gasoline, diesel, or electricity per year.
- Annual Maintenance/Repair Cost ($M$): The estimated cost of scheduled maintenance, oil changes, tires, and unexpected repairs per year.
- Annual Insurance/Registration/Fees ($I$): The annual total for auto insurance premiums, registration renewal, and local taxes.

What is 10 Year Cost of Ownership (TCO)?
The Total Cost of Ownership (TCO) is a financial metric designed to provide a comprehensive, long-term estimate of the expense associated with owning a vehicle. It goes far beyond the initial purchase price, encompassing every expense incurred from the day you buy the car until the day you sell or trade it in. Calculating TCO over a 10-year period is crucial for making fiscally responsible decisions, as depreciation and running costs often exceed the original sticker price.
Over a decade, recurring costs like fuel, maintenance, and insurance accumulate significantly. By factoring in the eventual resale value—the money you recover—the TCO offers a realistic measure of the car’s true financial drain. Ignoring TCO can lead to budget shortfalls, particularly as maintenance costs typically increase substantially in the later years of a vehicle’s life.
How to Calculate 10 Year Cost of Ownership (Example)
Let’s use the default input values to walk through the calculation:
- Calculate Depreciation: Subtract the Resale Value ($5,000) from the Initial Price ($35,000). Total Depreciation = $30,000.
- Calculate Annual Operating Costs: Sum the yearly expenses: Fuel ($1,800) + Maintenance ($750) + Insurance ($1,200) = $3,750.
- Calculate 10-Year Operating Costs: Multiply the Annual Operating Costs by the 10-year period: $3,750 $\times$ 10 = $37,500.
- Calculate Final TCO: Add the Total Depreciation (Step 1) and the Total Operating Costs (Step 3): $30,000 + $37,500 = **$67,500**.
Frequently Asked Questions (FAQ)
A: While financing is a critical component of a car’s overall cost, this simplified calculator focuses on core ownership and operational costs. For a more detailed TCO, you should manually add the total estimated interest paid over the 10 years to the final TCO figure.
Q: How do I estimate the 10-Year Resale Value?A: Resale value is estimated based on the vehicle’s model, reliability, and depreciation curve. Most cars retain 10-20% of their original value after 10 years. You can use online vehicle valuation tools or estimate 15% for an average model.
Q: Why is 10 years the standard period for this TCO?A: The 10-year period (or 100,000 to 150,000 miles) is often used because it represents the typical lifespan before major component failures become highly common and costly, giving a complete picture of the vehicle’s functional life.
Q: Is the TCO for an electric vehicle (EV) calculated differently?A: The formula is the same, but the components change. EVs typically have lower Annual Fuel (replaced by energy) and lower Annual Maintenance costs, but often have a higher Initial Price and potentially higher insurance premiums.
