Individuals are being misled by the monthly bill rather than the loan’s total cost, and they are paying for it. The Federal Reserve says that over $1.6 trillion in car loans is outstanding. Money expert Jean Chatzky, who has written Money Rules, says that the fine print on car loans can quietly sabotage your financial goals unless you’re vigilant.
She urges Americans to treat car financing with the same care that they would a home mortgage. Bankrate estimates that the typical auto loan rate on new cars is approximately 6.73% in mid-2025, and on used car loans is nearly 11.87%. That’s a big wad of cash, potentially thousands of dollars over a lifetime of loans.
Chatzky tells us that the key to car finance success lies in understanding terms like APR, loan-to-value ratios, and how your credit score affects you. With inflation still plaguing the auto sector and interest rates being unpredictable, the moment to revisit these 17 must-know car financing tips you just can’t afford to skip in 2025 is today.
Your Credit Score Is the Key to Admission to Favorable Loan Terms
This three-digit number is what lenders use to determine your interest rate, which can really impact your monthly payment and the total cost of the loan. Chatzky urges shoppers to check their scores at least 3 months before shopping, giving them time to challenge errors or build credit.
Never Look Only at the Monthly Payment
Chatzky calls this the “dealer’s favorite trap.” Salesmen like to toy around with monthly payments by stretching out the loan term, sometimes up to 84 months, while hiding elevated interest rates or fees. According to the Consumer Financial Protection Bureau (CFPB), Americans are paying $733/month on average for new cars, a 24% rise from pre-pandemic times.
Chatzky insists you bargain off the total cost of the vehicle, and not what your comfortably fitting monthly payment might be. A low payment can hide a financial time bomb.
Purchase Financing Before Purchasing a Car
Walking into a dealer without pre-approved financing is like showing up for a gunfight unarmed. Jean Chatzky recommends seeking financing from a bank, credit union, or online lender before going to the showroom. This puts you in the driver’s seat and prevents dealerships from charging you at their rate, a practice that adds $1,000 or more to the total price over the life of the loan, according to the National Consumer Law Center.
With competitive rates offered by online lenders like LightStream and PenFed, smart consumers comparison shop at least three before making a choice.
Avoid Rolling Negative Equity into a New Loan
Chatzky recommends taking the outstanding balance on your old car into a new loan to create a debt snowball. Based on a recent survey conducted by Edmunds, nearly 21% of 2024 trade-ins were made with negative equity, with an average still owed of $6,838.
This plan keeps consumers in a cycle of being upside down on their loans. Chatzky recommends waiting until you’re not underwater or paying off the cash deficit. Otherwise, you’re just trading debt for even more expensive debt.
Shorten Loan Terms—Even If Payments Are Bigger
Stretching your loan to 72 or 84 months will reduce your monthly payments, but does so at the expense of paying more interest, and possibly owing more than the car is worth. Jean Chatzky recommends keeping loans between 36 and 60 months for the most cost-efficient.
The longer the loan term, the longer you are exposed to market uncertainties and depreciation. From Kelley Blue Book, a new car loses 20%–30% in value in the first year, and an extended loan period will have you still paying full sticker price for a car that’s worth much less.
Avoid Dealer Add-Ons Included in Financing
Dealers include expensive add-ons like GAP insurance, extended warranties, and paint protection, all tacked onto your financing. Jean Chatzky says these padded deals will cost you $2,000 or more on your loan, and you’ll hardly notice. A National Automobile Dealers Association study says these add-ons increase dealers’ profit margins by 50% or more.
Compare shopping for third-party protection if you want extra coverage. Never sign for extras unseen; always ask for itemized pricing.
Don’t Assume Leasing Is Always Cheaper
While leasing might offer lower monthly payments, Jean Chatzky reminds consumers that leasing means you’re renting, not owning. A lease might cost $150–$250 less per month, but you’ll have nothing to show at the end of the term.
Chatzky recommends considering how you drive: if you drive to work or plan to own your vehicle for 5+ years, buying is usually a better value. Leasing includes mileage limits, wear-and-tear fees, and charges for early lease termination.
Refinance When Rates Decrease
Car loan refinancing can earn you thousands, provided you act fast when rates fall. Chatzky suggests consumers check out refinance deals annually, especially if their credit scores have improved. Online lenders RefiJet and AutoPay, up through mid-2025, offer refinance prices starting at 5.5% for super-qualified buyers.
A simple refinance can lower your payment by $50–$100/month or shorten your loan term. Just be cautious of prepayment fees or application charges.
Steer Clear of 0% APR Tricks
Dealerships will try to lure customers with 0% APR, but Chatzky warns that these deals come with conditions. Typically reserved for people with very good credit (above 780), these mean you forgo rebates or discounts that will save you money in the long run.
Do the math: a cash rebate might beat 0% interest if it knocks $3,000 off your principal. Always compare both offers side by side using an auto loan calculator.
Understand the Loan-to-Value Ratio (LTV)
The loan-to-value ratio is the amount you’re borrowing divided by the car’s value. Jean Chatzky says LTV affects approval odds, interest rates, and equity status. Lenders generally prefer LTVs under 100%. If you borrow more than the vehicle is worth (negative equity or add-ons), you’ll be charged higher rates.
Experian has found that those with LTVs greater than 120% default at a 34% increased rate. Make a larger down payment to reduce your LTV and make your terms acceptable.
Avoid “Yo-Yo” Financing Tactics
Jean Chatzky sternly advises against “yo-yo” financing—when you’re permitted to drive off the lot before financing is actually in place, then are called days later and asked to accept worse terms. This predatory practice disproportionately exploits buyers with subprime credit and is prohibited in most states, but it still occurs.
The Center for Responsible Lending estimates that over 20% of subprime borrowers have been exploited by this fraud. Chatzky urges you to never depart the dealership without having the financing contract thoroughly completed and signed. Always get written notice of loan approval.
If a dealer says they will “call you later,” this should be an enormous red flag. Bring your pre-approved financing with you to reduce the risk of ending up in this situation.
Add Total Ownership Costs
Financing an automobile isn’t merely a matter of monthly payments; it’s the total cost of ownership. Jean Chatzky urges consumers to include insurance, maintenance, gas, taxes, and depreciation when creating their budget. Chatzky advises that you also shop online for ownership calculators to compare different models before you purchase.
A lower initial price tag can end up costing more money in the long run in the form of insurance payments or gas mileage. Don’t allow financing to gloss over these not-so-well-known long-term expenses.
Always Read the Fine Print
Most auto loan contracts have stipulations that will cost you an arm and a leg. Jean Chatzky warns that early payment fees, mandatory arbitration, or exorbitant late fees are typically not seen until it’s too late. The Consumer Federation of America, in a 2024 study, found that more than 45% of consumers fail to read loan documents thoroughly.
Don’t get hurried and don’t let the dealer pressure you. Be blunt: “Is there a prepayment penalty?” “Are there required maintenance services?” Chatzky recommends reading every page, ideally with a financial advisor or consumer advocate. Remember: you’re signing a legally binding financial commitment, not ordering a burger.
Don’t Use Your Car Loan to Pay Off Other Debts
Rolling other debts like credit card balances or personal loans into your car loan might seem convenient, but it’s often a dangerous financial move. Jean Chatzky explained that car loans are secured debt against your vehicle, so you could lose your car if you’re in default.
Car loan delinquencies have been increasing, especially among millennials and Gen Z, the Federal Reserve reports, because these groups tend to roll over debt into a single loan. Chatzky is urging Americans to keep high-interest debt payments and car financing separate.
Use separate strategies and budgeting approaches to pay for each.
Be Aware of the Difference Between “Buy Here, Pay Here”
Dealers and Regular Lenders Chatzky warns of warning signs on “Buy Here, Pay Here” (BHPH) dealerships that make car loans in-house, frequently to subprime buyers. While convenient, these dealers usually charge interest rates of 20% or more, with hidden fees and usurious repossession.
According to the National Consumer Law Center, 1 out of 3 vehicles sold on BHPH lots are repossessed within 12 months. Chatzky suggests that consumers explore other avenues first, such as credit unions or community lenders, before turning to a BHPH dealer.
These cars typically do not report on-time payments to the credit bureaus, so they don’t amount to much for your credit.
Don’t Bypass the Down Payment
Zero-down financing can be tempting, but Jean Chatzky warns it has a way of getting you upside-down in your loan before you even step onto the lot. Putting down 10% to 20% will lower your loan-to-value ratio, lower your monthly payment, and establish immediate equity in your car.
Chatzky adds that a solid down payment signals to lenders your financial responsibility and helps you secure more favorable terms. Even when you save for longer, you’ll be paying years fewer in interest and won’t be upside down. Rule of thumb: the larger your down payment today, the less you’ll be sorry later.
Treat Car Financing as an Investment
Over the Long Term, Jean Chatzky believes that every financial decision, especially car financing, needs to be incorporated into your long-term wealth-building goals. A car is a depreciating asset, and poor borrowing decisions can sabotage your future savings for retirement, investments, or other goals.
With the average auto loan balance being $24,297 (according to Experian), errors are far from hypothetical. Chatzky encourages Americans to set aside the thrill of a new car and consider how this loan fits into their overall financial system. She suggests checking your overall debt-to-income ratio before you buy and thinking very carefully about opportunity cost.
Is money paid in interest or fees going to be better spent somewhere else? If the auto loan is preventing you from building wealth, it’s time to renegotiate the deal.
Key Takeaways
Jean Chatzky’s car financing guide is not a checklist; it’s a survival manual for getting through one of the biggest purchases Americans make. With higher interest rates, auto loan balances at all-time highs, and dealers offering ever-longer loan terms, there’s never been a greater need for financial prudence.
Clever financing doesn’t simply save money; it buys freedom. By applying these 17 essential lessons, consumers can avoid traps, build wealth, and take control of their financial destiny with confidence. As Chatzky herself says, “Money is not just about what you have, it’s about what you do with it.”
And in the automotive marketplace today, what you do at the financing table is potentially more crucial than what you drive off the lot.
