The 0% Auto Loan Is Back, and That Should Worry You

The 0% auto loan is back in showrooms, and it's being sold as a gift. It isn't one. After two years of brutal rates—averaging above 9% for used cars and over 7% for new ones at their peak—dealers are dangling zero-percent financing again on slow-selling models. Ford, Stellantis, Nissan and others have rolled out promotional APRs on everything from pickup trucks to EVs. On the surface, it looks like relief for buyers squeezed by $48,000 average new-car prices. Look closer and you'll see who's actually being rescued. It's not you. First, understand what 0% financing really is: a discount wearing a costume. When a dealer offers you zero percent, you typically forfeit the cash rebate you could have taken instead—often $2,000 to $5,000. Run the math on a $45,000 truck with a $3,000 rebate versus 0% for 60 months, and the "free money" often costs more than a 6% loan from your credit union. Dealers know most shoppers anchor on the monthly payment, not the total. Second, these offers are bait for a trap. Zero-percent deals almost always require pristine credit—think 700-plus, sometimes 780. If you don't qualify, you're bounced into the standard financing office, where the rate can swing wildly based on nothing more than how tired you look. Dealer-arranged loans routinely carry markups of 1 to 2.5 percentage points over the lender's base rate. That spread is pure profit, and it's legal in most states. Third, the real story behind the discounts: inventory is piling up. Automakers overproduced, EV demand cooled faster than expected, and dealers are sitting on the most unsold vehicles since early 2020. Incentives are climbing because lots are full, not because anyone at the finance company had a change of heart. Zero percent is a clearance sale on metal. And here's the part nobody mentions: subprime auto delinquencies are at their highest level in decades. More than 6% of subprime auto borrowers are at least 60 days behind, according to Fitch Ratings—worse than during the 2008 financial crisis. Lenders are tightening, and the easy promotional rates are reserved for the safest borrowers. Everyone else gets the 12% loan and a four-year reminder of it. So who benefits? Automakers move inventory. Dealers collect finance-office markups. Lenders book loans backed by an asset that loses 20% of its value the moment you drive off the lot. You get a depreciating machine and a payment that outlasts your enthusiasm for it. None of this means buying a car is stupid. It means the advertised rate is the beginning of the negotiation, not the end. Get preapproved by a credit union before you walk in. Ask for the out-the-door price in cash terms, then compare financing separately. Never let the finance office bundle the trade-in, the warranty, the paint protection and the rate into one friendly monthly number. That's not convenience—that's camouflage. The 0% loan isn't generosity. It's a pricing strategy aimed at people who won't do the arithmetic. Do the arithmetic. **The Takeaway:** Promotional auto rates are marketing, not charity, and the house always knows the math better than you do. If a deal only looks good as a monthly payment, it probably isn't a deal at all. Bring your own financing and your own calculator—the dealership's has a tilt.
