Why Making Payments on a Car Is Such a Poor Financial Decision

The Short Answer

The car payment has become so normalized in American life that most people treat it as inevitable — a permanent line item in the monthly budget, as fixed as rent or utilities. According to Experian’s State of the Automotive Finance Market report, the average new car payment in the United States now exceeds $700 per month, with loan terms commonly stretching to 72 or 84 months.

When the actual math of depreciation, interest costs, and opportunity cost is laid out clearly, the car payment emerges as one of the most reliably wealth-destroying habits in ordinary personal finance — not because cars are unnecessary, but because the way most people buy them is systematically expensive.

The Depreciation Problem

A new car loses approximately 20% of its value in the first year of ownership — and roughly 50% within three to five years. This depreciation is not recoverable. When you finance a new car, you are not just paying interest on a loan; you are using borrowed money to purchase an asset that is losing thousands of dollars in value every year, regardless of whether you drive it.

The most painful version of this is the “underwater” phenomenon — owing more on the car loan than the car is worth — which happens routinely with new cars purchased with small down payments and long loan terms. In this situation, you have paid thousands of dollars in loan payments while your net financial position in the car has actually gotten worse. You are going backwards.

The financially sound approach to vehicle ownership — buying a used vehicle that has already absorbed the steepest depreciation — is at odds with financing. Financing encourages purchasing new or near-new vehicles (because lenders are more willing to finance them) at precisely the price point where depreciation is most severe.

The True Cost of Auto Loan Interest

A $40,000 car financed at 7% over 72 months costs approximately $52,000 in total payments — $12,000 in interest paid to the lender for the privilege of driving a vehicle that will be worth approximately $18,000 to $20,000 at the end of the loan term. The consumer paid $52,000 for something worth $18,000 to $20,000.

Auto loan interest rates have risen significantly in recent years. Buyers with less-than-excellent credit routinely pay 10-15% interest on auto loans, which makes the total cost even more severe. At 12% interest, a $40,000 loan over 72 months costs approximately $58,000 in total payments.

The Opportunity Cost Is the Most Important Number

The most significant financial cost of car payments is rarely calculated: the opportunity cost of directing several hundred to over a thousand dollars per month into a depreciating asset instead of into investments that produce returns.

$600 per month invested in a broad index fund averaging 8% annual returns over ten years becomes approximately $110,000. Over thirty years, it becomes over $900,000. The person who eliminates the car payment and invests the equivalent sum instead does not just save the car payment — they lose access to the compounding that transforms modest monthly contributions into significant wealth over time. The car payment is not just expensive now; it is the most expensive decision’s downstream effects on what wealth accumulation could have looked like.

What the Research on Millionaire Behavior Shows

Thomas Stanley’s research on millionaire households in “The Millionaire Next Door” and subsequent research has consistently found that a majority of American millionaires do not have car payments — they buy used vehicles, often pay cash, and drive them for years. The behavior most associated with appearing wealthy (new car, large payment) is inversely correlated with actually becoming wealthy. The wealth-building behavior is systematically at odds with the wealth-signaling behavior.

The Alternative That Actually Works

The practical path out of the car payment cycle requires a period of temporary inconvenience: driving an older paid-off vehicle while saving to buy a reliable used car with cash. A $10,000 to $15,000 used car bought outright — a reliable three-to-five-year-old vehicle with documented maintenance history — provides dependable transportation without the monthly payment that compounds into hundreds of thousands of dollars of lost wealth over a lifetime.

The car payment feels normal because almost everyone around you has one. It is worth asking, occasionally, whether normalcy and financial wisdom are the same thing — because in this particular case, they reliably are not.
