From 4% to 22%: Car loan rates by credit score and where to find the lowest APRs

Experian Q4 2025 shows new car loan rates ranging from 4.66% (super prime) to 16.01% (deep subprime) and used car rates from 7.70% to 21.85%, highlighting a ~1,100–1,200bp spread between top- and bottom-tier borrowers. Provider examples: Capital One Auto Finance advertises APRs of 5.00%–6.11% with loans from $4,000 and terms 24–84 months (no prepayment penalty); myAutoloan lists rates as low as 4.09% with minimums around $8,000 and a 600 FICO threshold; CarMax offers used-vehicle loans $500–$100,000 (36–72 months) with no disclosed APR and varying state availability. Article emphasizes key rate drivers—credit score, loan term, down payment, lender type and vehicle age—which inform borrower risk and likely pricing outcomes.

Analysis

Rising effective APRs on lower-credit cohorts create a bifurcated market where lenders with proprietary origination/retail channels can capture outsized net interest margin while flow-dependent dealers and thin-margin retailers see demand elasticity bite. For used-car specialists that own both retail inventory and a captive-like financing funnel, incremental spread per loan translates directly to higher unit-level contribution and cross-sell optionality (warranty, F&I) — expect profit per transaction to rise faster than volumes fall over the next 3–9 months.

The credit-side second-order is in securitization mechanics: higher coupon originations and longer terms reduce prepay risk and extend WALs, improving coupons on newly issued senior auto ABS but raising tail risk in mezzanine tranches if unemployment or wage growth deteriorates. Watch 60+ day delinquencies and repossession timelines as the leading indicators; a 100–150 bps jump in 60+ DQ over a 6-month window historically pushes mezz spreads materially wider and forces mark-to-market moves in retail credit funds.

Catalysts that will meaningfully re-rate exposures are macro (Fed terminal rate and real wage trends), OEM incentives (aggressive new-car rebates compressing used prices), and regulatory/legislative scrutiny on dealer markups. A reversal can come quickly with either a sustained 75–100 bps ease in policy rates or a sharp improvement in payrolls that restores refinancing velocity — both would narrow financing spreads and compress F&I-driven outperformance within 3–6 months.

Key Decisions for Investors

• Long KMX (CarMax) — initiate a 2% portfolio position (equity) with a 6–12 month horizon to capture financing margin tailwinds and F&I optionality; target +35% upside, stop-loss at -12% to limit sensitivity to a sudden used-car demand collapse.
• Relative trade: Long COF (Capital One) / Short ALLY (Ally Financial) — equal notional pair for 6–12 months. Rationale: COF’s diversified unsecured + auto mix should outperform an auto-concentrated lender if ABS spreads widen or delinquencies tick; target 20% relative outperformance, stop-loss if pair moves against by 10% (monitor ABS 3y spreads and 60+ DQ weekly).
• Leveraged directional: Buy COF 9–12 month calls (size no more than 0.5% notional) — convex way to express higher consumer lending yield capture without balance-sheet exposure. Reward asymmetry ~3:1 if policy rates stay higher-for-longer and credit mix improves; theta decay is the primary risk, cut if implied vols rise >30% intraday or macro payrolls beat consensus by >200k.
