- As of Q4 2025, borrowers with FICO scores of 661 or higher captured 69.2% of all retail vehicle financing, per Experian — making 661 the practical floor for competitive auto loan pricing.
- The spread between super prime borrowers (4.66% APR on new cars) and deep subprime borrowers (16.01%) exceeds 11 percentage points — a gap that compounds over a five-year loan on an average $43,582 new vehicle.
- Average approved scores run 753–757 for new car loans versus 689–691 for used, per Experian Q4 2025 — used vehicles offer a more accessible credit threshold for nonprime borrowers.
- AI-native lending platforms are now evaluating 1,000+ data points beyond FICO, expanding approvals for borrowers who may not qualify under traditional bank underwriting models.
What’s on the Table
16.01% versus 4.66%. Those two figures, drawn from Experian’s Q4 2025 State of the Automotive Finance Market Report, define the actual stakes of the credit score conversation for anyone financing a vehicle today. Super prime borrowers — those with FICO scores between 781 and 850 — are locking in new car loans at a 4.66% average annual percentage rate. Deep subprime borrowers face 16.01%. On an average new vehicle loan of $43,582, as of June 15, 2026, that spread does not stay abstract for long. It reshapes a monthly budget for the next five years in ways a single rate number undersells.
According to Google News, NerdWallet’s coverage of auto lending captures the practical reality plainly: “A lower credit score won’t necessarily keep you from securing a car loan, but it might spike your interest rate, leading to higher payments.” The Federal Reserve Bank of New York’s Q1 2026 data puts the scale of this market in context: total outstanding auto loan balances reached $1.69 trillion, an $18 billion increase from the prior quarter, representing 8.9% of all American consumer debt. Americans borrowed $180.8 billion in new auto loans in Q4 2025 alone. This market finances nearly every credit profile — but it prices them very differently.
Side-by-Side — How the Credit Tiers Price Out
Experian’s Q4 2025 report breaks the market into five credit bands. The distribution as of that quarter tells the story of who is actually financing vehicles and at what cost:
- Super prime (781–850): 33.11% of all vehicle financing. Average APR of 4.66% for new cars, 7.70% for used.
- Prime (661–780): 36.05% of financing. Combined with super prime, these two tiers capture roughly 69% of all retail vehicle deals.
- Nonprime (601–660): 15.53% of financing. Rates begin climbing meaningfully below the 661 mark.
- Subprime (501–600): 13.32% of financing.
- Deep subprime (300–500): 1.99% of financing, facing average rates of 16.01%.
There is no absolute score floor — some lenders approve borrowers with scores as low as 500–550 — but 661 is where competitive pricing typically begins. Below that mark, each tier down represents a meaningful rate step-up. The total spread across the full range exceeds 11 percentage points, per Experian’s market analysis. Call me skeptical of anyone who frames this as a minor difference: on a five-year loan, it compounds into a materially different debt management outcome.
Chart: Average auto loan APR for super prime borrowers (4.66% new cars), the current 60-month new car market average (6.98% as of early June 2026, Bankrate), and deep subprime borrowers (16.01%) — Q4 2025 Experian data unless noted.
As of early June 2026, Bankrate pegs the current average rate at 6.98% for a 60-month new car loan — a useful anchor that lands between the two extremes. The average new car monthly payment stands at $767 as of Q4 2025, on average loan amounts of $43,582.

New vs. Used: The Hidden Divide
One pattern that rarely surfaces in the credit score conversation: the underwriting standards for used vehicle loans differ meaningfully from those applied to new car financing. Experian’s Q4 2025 data shows average approved FICO scores of 753–757 for new car loans and 689–691 for used — roughly a 60-point gap in where lenders are drawing their effective line.
The logic tracks with basic risk math. Average new vehicle loan amounts reached $43,582 in Q4 2025, while used vehicles averaged $27,528. Lower loan amounts mean lower absolute dollar exposure for lenders — they can price in more credit risk at a smaller loan size. For a borrower sitting in the 640–680 FICO range, this dynamic is directly relevant: a used vehicle application may find a substantially more favorable reception than a new car loan request carrying the same credit profile. Experian’s Q1 2026 State of the Automotive Finance Market Report also highlighted growth in non-prime segments and increased used financing share, suggesting lenders are actively expanding their appetite in this space. Industry analysis consistently shows that traditional banks are the least flexible at lower scores, while credit unions — particularly for existing members — are sometimes more willing to work with nonprime applicants as part of their member-service mandate.
Where AI Credit Tools Are Reshaping Who Gets Approved
In May 2026, TORQ launched an AI-native indirect auto lending platform in the United States, targeting credit unions, banks, and captive finance companies with advanced credit decisioning capabilities. It’s one visible entry point in a structural shift that has been building for several years. Platforms like Upstart — among the most established AI credit tools in consumer lending — already evaluate more than 1,000 data points beyond the traditional FICO score. Automated decisioning rates at mid-market credit unions have climbed from 28% to 75%, enabling up to 20x faster loan processing and cutting end-to-end origination cycles by over 90%.
The AI-powered lending market was valued at $109.73 billion in 2024 and is projected to reach $2.01 trillion by 2037, a 25.1% compound annual growth rate, according to industry projections. For borrowers managing broader debt management priorities alongside a car purchase, this shift matters practically, not just theoretically. Your FICO score is a lagging indicator — it reflects past credit behavior, often with significant lag and incomplete coverage of your actual financial picture. The newer generation of AI credit tools is beginning to evaluate leading signals: income stability, payment consistency across non-traditional accounts, behavioral data that a static bank model never sees. This mirrors a pattern Smart Property AI tracked in the mortgage market, where elevated rates pushed lenders toward broader underwriting frameworks to sustain volume — the same playbook now unfolding in auto lending.
Which Fits Your Situation
Pull your FICO Auto Score before approaching any dealership or lender. Auto lenders frequently use industry-specific FICO versions that can differ from your generic credit score by 20–30 points in either direction — knowing which tier you actually land in tells you which lender category to prioritize. Traditional banks are least likely to approve lower scores. Credit unions offer more flexibility, especially for existing members. If your score sits in the 580–660 range, AI credit tools and AI-native platforms are worth exploring; they may evaluate your application on factors a conventional bank’s static model never surfaces. Consistent debt management habits — on-time payments, lower revolving balances — feed both traditional and AI underwriting models.
LendBuzz’s lending experts note that putting down 15%–20% of the vehicle price generates “meaningfully better offers than if you apply with zero down.” Bankrate’s financial advisors set the target at at least 20% of the purchase price. On an average used vehicle at $27,528, that’s roughly $5,500 down. On a new vehicle at $43,582, you’re looking at approximately $8,700. The down payment reduces your loan-to-value ratio — the amount owed relative to the vehicle’s market value — which directly lowers lender risk and typically produces a better rate offer. Utilization moves the needle in credit cards; loan-to-value moves it in auto lending.
A cosigner with a prime or super prime FICO score doesn’t just improve approval odds — it can shift the effective rate tier used to price the entire loan. Many lenders price a cosigned loan based on the stronger credit profile in the application. If a cosigner scores 760 and you score 625, the loan may be priced at or near prime rates rather than nonprime. The cosigner assumes full legal liability for the debt if payments stop, so this is a meaningful financial commitment for whoever agrees. As a targeted intervention for a borrower who needs a vehicle now rather than after a 12-month credit-building window, it remains one of the most immediately effective levers available — used correctly, it’s a rate tool, not just an approval workaround.
Frequently Asked Questions
Can I buy a car with a 600 credit score in the current lending environment?
Yes. As of Q4 2025, subprime borrowers in the 501–600 range accounted for 13.32% of all vehicle financing, per Experian data. Some lenders approve applicants with scores as low as 500–550. The practical cost is a significantly higher interest rate — deep in the subprime tier, average rates have reached 16.01%. Credit unions and AI-powered platforms tend to be more accessible at this score range than traditional banks. A larger down payment and a cosigner can partially offset a lower score in a lender’s eyes if buying now is necessary.
What interest rate will I get with my credit score on a car loan?
Rate maps closely to your credit tier. As of Q4 2025, Experian data shows super prime borrowers (781–850) averaged 4.66% APR on new cars and 7.70% on used. Deep subprime borrowers faced an average of 16.01%. The current market average for a 60-month new car loan sits at 6.98% as of early June 2026, per Bankrate. Your actual offer will reflect which tier your score lands in — and which lender type you approach (bank, credit union, or AI-native platform). The spread across the full range exceeds 11 percentage points, so tier placement is not a minor variable.
How much should I put down on a car if I have bad credit?
Target 15%–20% of the vehicle’s purchase price. Bankrate financial advisors recommend at least 20%; LendBuzz lending experts note that 15%–20% produces meaningfully better rate offers than zero down. On a $27,528 average used vehicle, 20% is roughly $5,500. The down payment reduces your loan-to-value ratio, which is one of the primary levers nonprime borrowers have to offset weaker credit signals in an underwriting model — whether traditional or AI-driven. Combining a 20% down payment with a cosigner and a credit union application is a reasonable three-part approach for borrowers in the 580–640 range.
Will a cosigner help me get a better car loan rate with bad credit?
Yes, often significantly. Many lenders price a cosigned loan based on the stronger applicant’s credit profile. A cosigner with a 750+ FICO on an application from a 620-score borrower can result in prime-range pricing rather than subprime rates — a difference that can easily run several percentage points. The cosigner bears full legal liability if payments stop, so both parties need to understand the stakes. Have a clear payment arrangement in place before asking someone to cosign. Used as a deliberate rate tool rather than just an approval safety net, a cosigner can meaningfully change the debt management math on a multi-year loan.
What’s the difference between new and used car loan credit requirements?
The gap is roughly 60 FICO points in practice. As of Q4 2025, Experian reports average approved scores of 753–757 for new car financing and 689–691 for used. Used vehicles also carry lower average loan amounts ($27,528 versus $43,582 for new), which reduces the absolute dollar risk for lenders and opens the approval window further down the credit range. Experian’s Q1 2026 report highlighted growth in non-prime used financing specifically. If your score is in the 640–680 range and you need financing now, the used vehicle route generally offers a more favorable environment than applying for a new car loan with the same profile.
