For years, the “forever loan” has been the ghost haunting the American auto market. It is the 72-month, 84-month, or even 96-month financing agreement that stretches a car payment well past the vehicle’s peak utility, often leaving the borrower owing more than the car is worth. To many economists, these extended terms are a red flag—a sign of a consumer base pushed to the brink by inflation and soaring sticker prices.
But Sanjiv Yajnik, the president of Capital One Auto, sees a different story. While the optics of an eight-year car loan may seem precarious, Yajnik argues that the underlying data suggests a surprisingly disciplined consumer. From his perspective, the extension of loan terms isn’t a symptom of desperation, but a calculated strategy to maintain a stable lifestyle in a high-cost environment.
The core of the argument rests on the payment-to-income ratio. While the headline numbers—higher interest rates, inflated used car prices, and rising insurance premiums—suggest a crisis, Capital One’s internal data shows that the percentage of income consumers dedicate to their vehicles has remained remarkably flat since 2019. By stretching the loan term, borrowers are effectively capping their monthly expenses to keep their budgets from breaking.
The Affordability Paradox
The tension in the current market is a matter of perspective. On one hand, the cost of ownership has risen sharply. Capital One reports that median monthly car payments have climbed from $390 in 2019 to $525 today. In a vacuum, a $135 monthly increase would signal a significant squeeze on the American household.
However, Yajnik points out that when you look at every quintile of salary and earnings, the payment-to-income ratio has remained steady at approximately 10%. According to the lender, 80% of car purchasers who finance a vehicle stay below the 15% threshold generally recognized by the industry as the upper limit of affordability.
This suggests that consumers are not spending a larger slice of their paycheck on transportation. they are simply rearranging the timeline of their debt to ensure that slice doesn’t grow. In Yajnik’s view, this is a sign of responsibility. Because a vehicle is often a non-discretionary expense—essential for getting to work and maintaining a livelihood—prioritizing the monthly payment over the total interest cost is a rational survival strategy.
The Risk of Going ‘Underwater’
While the monthly budget may look healthy, the long-term equity position of the borrower is where the danger lies. This is the primary concern for industry analysts and firms like Edmunds. When a loan is stretched to 84 months, the principal is paid down much more slowly. If the vehicle’s market value drops faster than the loan balance, the borrower becomes “underwater,” or holds negative equity.
The data from Edmunds highlights a growing trend of buyers entering new loans while still owing money on their previous cars. Through April of this year, roughly 26% of used vehicle purchases involving a trade-in carried negative equity, averaging $5,105—a 35% increase since 2019. For new vehicles, the situation is more acute: the average negative equity trade-in during the first quarter reached $7,183.
The correlation with loan length is stark. According to Jessica Caldwell, head of insights for CarMax’s Edmunds, 90.2% of new vehicle loans involving negative equity trade-ins had terms of at least 72 months, with 43% extending to 84 months. This creates a compounding debt cycle where the borrower is essentially financing the “ghost” of their previous car into the price of their new one.
The Math of Monthly Breathing Room
The trade-off for the consumer is a choice between total cost and monthly cash flow. To illustrate, consider a $30,000 vehicle financed at a 9% annual percentage rate (APR). The difference between a standard four-year loan and a seven-year “forever loan” is significant in terms of raw interest, but the monthly impact is what drives the decision.
| Loan Term | Monthly Payment (Approx.) | Total Interest Paid | Equity Build-up Pace |
|---|---|---|---|
| 48 Months | $745 | $5,760 | Rapid |
| 84 Months | $481 | $8,860 | Slow |
| Difference | $264 Savings | $3,100 Extra Cost | High Risk of Negative Equity |
For a lower-income household, $264 a month is the difference between meeting other obligations—like rent or groceries—and falling behind. For these borrowers, paying an extra $3,100 over the life of the loan is a fee they are willing to pay for the ability to afford a reliable vehicle today. Yajnik argues that as long as the consumer uses the car to earn money and maintains it properly, the slow build-up of equity is a secondary concern.
The Long-Term Maintenance Gamble
There is, however, a hidden cost to the forever loan that doesn’t appear on a financing spreadsheet: maintenance. To make a long-term loan viable, the consumer must keep the vehicle for a longer period. While this avoids the negative equity trap of trading in too early, it pushes the car into the “high-maintenance” phase of its lifecycle.
As vehicles age past the five-year mark, the likelihood of major repairs—transmission failures, engine issues, or electronics breakdowns—increases. If a borrower is still paying a monthly installment on a car that requires a repair exceeding its current value, the “responsible” monthly budget can collapse instantly. The consumer is then faced with a choice: pay for an expensive repair on a car they don’t own outright, or scrap the vehicle while still owing thousands to the lender.
Despite these risks, the current market reflects a stark divide in philosophy. Where some see a looming debt bubble, Capital One sees a consumer base that has adapted to a new economic reality by leveraging time to protect their monthly income.

The stability of this “flat” payment-to-income ratio will likely be tested as the Federal Reserve begins to navigate interest rate adjustments. The next major indicator of consumer health in the auto sector will be the upcoming quarterly delinquency reports from major lenders, which will reveal whether these long-term loans are remaining sustainable or if the “forever loan” is finally reaching its breaking point.
