Money MoveAmericans are spending a record 767 dollars a month on new car payments. But here is the part nobody talks about at the dealership: in the first year of your loan, up to 65 percent of every payment goes to the bank, not toward your car.
That means on a typical new car loan, you could hand over 5,000 dollars or more in pure interest before you even put a real dent in what you owe.
TL;DR
- The average new car payment hit a record 767 dollars per month in Q4 2025. Used car buyers pay 537 dollars per month at nearly double the interest rate.
- In the first year of a typical auto loan, 50 to 65 percent of each payment goes to interest, not principal. You are renting money before you start owning the car.
- A 5-minute rate check and a shorter loan term can save you thousands. Do it before your next payment.

The Interest Trap, Explained
Auto loans use a system called amortization, which is a fancy word for front-loading interest. In the early months of your loan, the bank takes its cut first. You pay interest on the full balance before you start chipping away at the principal, which is the actual amount you borrowed.
Here is what that looks like in practice on a 43,582 dollar new car loan at 6.5 percent APR over 60 months:
| Month | Payment | Interest Portion | Principal Portion | Remaining Balance |
|---|---|---|---|---|
| 1 | 852 dollars | 236 dollars | 616 dollars | 42,966 dollars |
| 6 | 852 dollars | 225 dollars | 627 dollars | 39,889 dollars |
| 12 | 852 dollars | 213 dollars | 639 dollars | 36,674 dollars |
| 24 | 852 dollars | 187 dollars | 665 dollars | 29,709 dollars |
| 36 | 852 dollars | 159 dollars | 693 dollars | 22,282 dollars |
| 60 | 852 dollars | 5 dollars | 847 dollars | 0 dollars |
How we calculated this
We used a standard amortization formula: monthly interest equals the remaining balance times the annual rate divided by 12. Payment amount equals the loan amount times the monthly rate divided by one minus the quantity one plus the monthly rate raised to the negative power of the number of months. All figures rounded to the nearest dollar. Your numbers will differ based on your exact rate, loan amount, and term. Run your own numbers at any free amortization calculator online.
In the first 12 months, you pay approximately 2,718 dollars in interest alone. That is 26 percent of your total annual payments going to the bank, not your car.
Used Car Buyers Get Hit Even Harder
If you bought used, the math gets uglier. Used car loan rates average 11.26 to 11.40 percent APR according to Experian Q4 2025 data. That is nearly double the new car rate.
On a 27,528 dollar used car loan at 11.3 percent over 60 months:
| Metric | Amount |
|---|---|
| Monthly payment | 601 dollars |
| First month interest | 259 dollars |
| Year 1 total interest | 2,926 dollars |
| Total interest over 60 months | 8,550 dollars |
| Total cost of the car | 36,078 dollars |
You are paying 8,550 dollars in interest on a 27,528 dollar car. That is a 31 percent markup just for the privilege of borrowing money.
Your Credit Score Is the Biggest Hidden Cost
The difference between a good rate and a bad rate is not small. It is thousands of dollars.
| Credit Tier | Typical New Car APR | Total Interest on 43,582 Dollar Loan (60 months) |
|---|---|---|
| Super-prime (781 and above) | 4.88 percent | 3,869 dollars |
| Prime (661 to 780) | 6.51 percent | 5,227 dollars |
| Near-prime (601 to 660) | 9.73 percent | 7,970 dollars |
| Subprime (501 to 600) | 13.04 percent | 10,960 dollars |
| Deep subprime (300 to 500) | 16.89 percent | 14,641 dollars |

A deep subprime borrower pays 14,641 dollars in interest on the same car that costs a super-prime borrower 3,869 dollars in interest. That is a 10,772 dollar penalty for having a lower credit score.
The 72-Month and 84-Month Trap
Dealers love long loan terms because they make the monthly payment look affordable. But stretching to 72 or 84 months means you pay interest for years longer, and you stay underwater on your car, meaning you owe more than it is worth, for most of the loan.
On a 43,582 dollar loan at 6.5 percent:
| Loan Term | Monthly Payment | Total Interest Paid | Months Underwater |
|---|---|---|---|
| 48 months | 1,033 dollars | 6,002 dollars | 6 to 12 months |
| 60 months | 852 dollars | 7,527 dollars | 12 to 24 months |
| 72 months | 732 dollars | 9,149 dollars | 24 to 36 months |
| 84 months | 647 dollars | 10,853 dollars | 36 to 48 months |
The difference between a 48-month and an 84-month loan is 4,851 dollars in extra interest. That lower monthly payment is not saving you money. It is costing you nearly 5,000 dollars.
What You Should Actually Do
- Check your current rate right now. Pull up your loan statement or call your lender. If your rate is above 7 percent on a new car or above 10 percent on a used car, you are likely overpaying. Time needed: 5 minutes.
- Get refinance quotes from at least 3 lenders. Credit unions typically offer rates 1 to 2 percentage points lower than dealership financing. Use your VIN and current payoff amount. Time needed: 30 minutes across multiple sites.
- Run the amortization math on your specific loan. Search for any free auto loan amortization calculator. Enter your balance, rate, and remaining term. Look at how much of your next 12 payments goes to interest. Time needed: 5 minutes.
- If you are early in a long-term loan, consider refinancing to a shorter term. Yes, the monthly payment goes up. But you will save thousands in interest and stop being underwater sooner.
- Before your next car purchase, get pre-approved BEFORE visiting the dealer. Dealer financing averages 1 to 2 percent higher than what you can get on your own. Walk in with your own rate as leverage.
FAQ
Does refinancing hurt my credit score? Multiple auto loan inquiries within a 14-day window count as a single hard pull on your credit report according to FICO scoring models. So rate-shop within two weeks and the impact is minimal, typically 5 points or less.
How do I know if I am underwater on my loan? Compare your loan payoff amount, which is on your statement or available by calling your lender, to your car's current market value on sites like Kelley Blue Book or Edmunds. If you owe more than it is worth, you are underwater.
Is it worth refinancing if I only have 2 years left? Usually not. Most of your interest is already paid in the early years due to amortization. Refinancing makes the biggest difference in the first half of your loan term.
Why did the dealer give me a higher rate than I qualified for? Dealers often mark up the rate by 1 to 2 percent and keep the difference as profit. This is legal and extremely common. Always compare the dealer's offer to an outside pre-approval.
Can I make extra payments to reduce interest? Yes, but confirm with your lender that extra payments go toward principal, not future payments. Some lenders apply extra payments to the next month's bill instead of reducing your balance, which does not save you interest.
