ChatGPT Reveals How Much It Costs To Pay Off a Used Car in 5 Years

In February, Kelley Blue Book (KBB) chronicled the end of an automotive era. The last sub-$20,000 new car had rolled off the line as every major automaker moved to price its most affordable entry-level vehicle beyond the high teens. 

In May, KBB followed up with a report that the average new car was selling for just shy of $50,000 — $49,461, to be exact. Those prices have forced budget-conscious buyers to the used market — but they’re not exactly giving away previously owned vehicles. Also in May, KBB reported that the average used car price had again topped $26,000 to $26,342.

Most people don’t have that kind of cash, so they finance, typically for 60 months. I asked ChatGPT how much it would cost the average used car buyer to pay off their vehicle over five years. What I learned is that if you’re in the market for a previously owned set of wheels, start saving.

May data from Edmunds, the most recent available, reveal an prohibitively expensive national patchwork of average used-car annual percentage rates (APRs).

Rates are still under 8%, albeit barely, in Vermont, Washington and Utah, with 10 others averaging between 8% and 9%. Most of the country, however, averages between 9% and 11%, with a dozen states suffering from average rates above 11% and 12%. Mississippi leads the nation with an average APR of 12.64%. 

I asked ChatGPT to crunch those ugly numbers based on the average $26,342 used vehicle for a 60-month loan term. The artificial intelligence (AI) chatbot provided a table, converted to bullet points here, showing that many buyers will pay nearly one-third of the car’s value in combined interest.

  • Monthly payment: $534.22

  • Total paid over 5 years: $32,053.20

  • Total interest paid: $5,711.20

  • Monthly payment: $546.82

  • Total paid over 5 years: $32,809.20

  • Total interest paid: $6,467.20

  • Monthly payment: $559.66

  • Total paid over 5 years: $33,579.60

  • Total interest paid: $7,237.60

  • Monthly payment: $572.73

  • Total paid over 5 years: $34,363.80

  • Total interest paid: $8,021.80

  • Monthly payment: $586.01

  • Total paid over 5 years: $35,160.60

  • Total interest paid: $8,818.60

Edmunds notes that there’s no magic formula for how much is too much to spend on a car, but generally, experts recommend spending no more than 10% to 15% of your after-tax income on monthly payments.

ChatGPT determined that even at 12% interest, the $586.01 monthly payment is 10.05% of a $70,000 income. If you make that much after taxes, congratulations — a monthly payment approaching $600 for an average used car is somehow affordable.
