TrueCostAuto is a vehicle Total Cost of Ownership (TCO) calculator that helps you estimate the real cost of owning a car before you buy it.

Whether you're shopping for a new or used vehicle, TrueCostAuto goes beyond the sticker price and monthly payment to calculate the full cost of ownership over time.

It estimates key expenses including depreciation, fuel or charging, insurance, maintenance, repairs, financing, taxes, registration, and resale value.

Compare multiple vehicles side by side to discover which car is truly more affordable over 1, 5, 13, or even 100 years.

Perfect for comparing EVs, hybrids, and gasoline vehicles, TrueCostAuto helps you answer questions like:

  • Can I really afford this car?
  • Which car costs less to own?
  • Is an EV cheaper than a gas car?
  • Should I buy new or used?

Make smarter car-buying decisions with complete ownership cost analysis—not just monthly payments.

FAQs (Frequently Asked Questions)

Here are the answers to some of the most common questions about vehicle Total Cost of Ownership (TCO) and how to use TrueCostAuto.

1. What is Total Cost of Ownership (TCO)?

Total Cost of Ownership (TCO) is the actual cost of owning and operating a vehicle over time. It goes far beyond the initial purchase price or monthly loan payment to include key expenses such as depreciation, fuel or charging, insurance, maintenance, repairs, taxes, registration, financing costs, and eventual resale value.

2. Why should I use TrueCostAuto instead of a simple loan calculator?

A loan calculator only tells you how much you pay each month to purchase the car. TrueCostAuto calculates how much the car will actually cost you to own and run. For example, an electric vehicle (EV) might have a higher monthly loan payment but significantly lower fuel and maintenance costs, making it cheaper overall than a gas car in the long run.

3. How does the Purchase Recommendability Score (PRS) work?

PRS is a proprietary scoring system that combines objective financial TCO data with your subjective preferences (such as styling, driving feel, or safety features). You can customize the weights of these preferences, and the app calculates a personalized score from -200 to 200 to help you decide if a vehicle is right for you.

4. Is an electric vehicle (EV) cheaper to own than a gas car?

It depends on your local electricity rates, fuel prices, annual driving mileage, and how long you plan to keep the vehicle. Generally, EVs have higher depreciation initially and higher purchase prices, but their operating costs (charging and maintenance) are much lower. TrueCostAuto allows you to compare them side-by-side using your own local rates to find the true winner.

5. Should I buy a new or used car?

New cars suffer from rapid initial depreciation but come with warranties and lower maintenance costs. Used cars have lower depreciation but may require more frequent repairs. TrueCostAuto helps you input different depreciation rates and maintenance expectations to compare the financial impact of both choices.
