Americans are buying more cars than ever, but many are stretching their budgets to do so. With rising insurance costs, higher taxes, and wages that are not keeping pace with inflation, the question arises: are car payments becoming too high for the average buyer? This post explores the risks of overextended car loans, the potential for a subprime loan bubble collapse, and what the future might hold for auto financing in the United States.

How Americans Are Stretching Their Car Budgets


Car ownership remains a priority for many Americans, but the way people finance their vehicles has changed dramatically. Loan terms have lengthened, and monthly payments have increased. According to recent data, the average new car loan term is now around 72 months, or six years, which is longer than a typical mortgage in some cases. This means buyers are committing to payments for a longer period, often paying more interest over time.


At the same time, monthly car payments have climbed. The average monthly payment for a new car in 2023 was approximately $700, while used car payments averaged around $500. For many households, these payments consume a significant portion of their monthly income, especially when combined with rising costs for insurance and taxes.


When Does a Car Payment Become Too High?


Financial experts often recommend that all vehicle expenses, including loan payments, insurance, fuel, and maintenance, should not exceed 15% to 20% of a household’s monthly take-home pay. When car payments alone approach or exceed 10% to 15%, it signals potential overextension.


For example, a household earning $4,000 per month should ideally keep car payments under $600. If payments rise above this level, it leaves less room for other essential expenses and savings. Many Americans, especially those with subprime credit scores, are already pushing these limits.


The Risk of Longer Loan Terms and Rising Defaults


Longer loan terms reduce monthly payments but increase the total interest paid and the risk of negative equity. Negative equity occurs when the loan balance exceeds the car’s value, making it difficult for owners to sell or trade in their vehicles without incurring losses.


This situation is particularly risky for subprime borrowers who often face higher interest rates and less favorable loan terms. If economic conditions worsen, these borrowers may struggle to keep up with payments, leading to increased repossessions.

What Could Trigger a Subprime Auto Loan Bubble Collapse?


Several factors could cause the subprime auto loan market to collapse:


  • Rising interest rates: Higher rates increase monthly payments, making loans less affordable.

  • Inflation outpacing wage growth: When wages do not keep up with rising living costs, borrowers have less disposable income for car payments.

  • Increasing insurance and tax costs: These add to the total cost of vehicle ownership, squeezing budgets further.

  • Economic downturn or recession: Job losses or reduced income can lead to missed payments and defaults.

  • Declining used car values: If used car prices fall, negative equity rises, increasing default risk.


The combination of these factors could lead to a surge in repossessions and financial strain on lenders, similar to the housing crisis but on a smaller scale.


Which Automakers Are Most Vulnerable?


Not all car manufacturers face the same risks. American automakers like Chrysler, Chevrolet, and Ford have a larger share of subprime borrowers and longer loan terms. These companies may feel the impact of a market downturn more acutely.


By contrast, most Japanese automakers such as Toyota, Honda, and Subaru tend to attract buyers with stronger credit profiles and offer vehicles that hold their value better. This makes their financing portfolios more stable and less vulnerable to a subprime loan collapse.


The Impact of Rising Insurance and Taxes


Insurance premiums have increased steadily over the past few years due to higher repair costs, more claims, and inflation. Similarly, vehicle registration fees and taxes have risen in many states. These added expenses increase the total monthly cost of owning a car beyond just the loan payment.


For many households, these rising costs mean less flexibility in their budgets. When combined with stagnant wages, it creates a financial squeeze that can lead to missed payments or the decision to delay maintenance, which can further reduce vehicle value.


When Could the Next Recession or Market Downturn Hit?


Predicting the exact timing of a recession is difficult, but several indicators suggest economic challenges ahead:


  • Inflation remains above the Federal Reserve’s target.

  • Wage growth is slow compared to rising living costs.

  • Consumer debt levels, including auto loans, are near record highs.

  • Global economic uncertainties persist.


If these trends continue, the risk of a recession or market downturn within the next 12 to 24 months is significant. During such times, consumers often cut back on spending, and loan defaults tend to rise.

What Can Consumers Do to Protect Themselves?


  • Keep car payments manageable: Aim for payments under 15% of take-home pay.

  • Consider shorter loan terms: While monthly payments may be higher, total interest paid will be lower.

  • Maintain good credit: This helps secure better loan terms and lower interest rates.

  • Budget for insurance and taxes: Include these costs when calculating affordability.

  • Avoid negative equity: Make a larger down payment or choose vehicles that hold value well.

  • Build an emergency fund: This can cover unexpected expenses or temporary income loss.


What Should Lenders and Policymakers Watch?


Lenders need to monitor loan portfolios closely for signs of rising defaults, especially in the subprime segment. They should also consider tightening lending standards and offering financial counseling to borrowers.


Policymakers might explore measures to protect consumers, such as caps on loan terms or interest rates, and programs to support those struggling with payments.
