Frequently Asked Questions

Everything you need to know.

What is the biggest cost of owning a car?

Depreciation, by far. The average new car loses 20% of its value in year one and another 40-50% over 5 years. On a $40,000 vehicle, that is $24,000-$28,000 in depreciation alone. Financing costs are second at a typical 7-8% APR, followed by insurance. Fuel and maintenance are the smallest components for most drivers at typical mileage.

How is 5-year net cost calculated?

5-year net cost = all cash spent (down payment + loan payments + fuel + insurance + maintenance) minus the residual value of the vehicle at year 5. This gives a true ownership cost that accounts for the equity you retain, making it comparable to a lease calculation over the same period.

Is the Car Total Cost of Ownership Calculator — 5-Year All-In Cost free to use?

Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.

Does using the Car Total Cost of Ownership Calculator — 5-Year All-In Cost affect my credit score?

No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.

Are the results personalized financial advice?

No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.

What should I do after seeing the result?

Use the recommendation module on this page to compare auto loan rates, or run Money Map to compare this loans & credit decision with your other opportunities.

How does SwitchWize choose related offers?

Related offers are matched by the calculator surface (auto) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.

How fresh are the rates and offers shown?

Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.

Where can I see the ranking methodology?

The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.

Can Money Map use this result?

Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

The sticker price is only the beginning. A $35,000 car over 5 years typically costs $50,000-$65,000 all-in once you add depreciation, interest, $3.50/gallon fuel, insurance, and maintenance. Depreciation alone accounts for 40-50% of most 5-year ownership costs. This calculator surfaces all of that so you can compare the real cost of two different vehicles or the buy-vs-lease decision on a fair basis.
