The best advertised auto-loan rates available in the latest September 2026 data start below national averages, but only well-qualified borrowers who meet each lender’s rules receive them. Bankrate’s national benchmark was 7.00% for a 60-month new-car loan and 7.50% for a 48-month used-car loan on September 23, 2026. Navy Federal advertised new-car APRs as low as 3.89% for 12–36 months, while Interior Federal listed 4.24% for up to 60 months. Treat those lender figures as rate floors, not guaranteed quotes.
Current auto-loan rate snapshot
These figures are not interchangeable: the Bankrate numbers are national benchmark profiles, while the credit-union numbers are advertised “as low as” APRs subject to eligibility, credit and vehicle conditions.
| Source and date | Loan profile | Published APR | How to read it |
|---|---|---|---|
| Bankrate Monitor, September 23, 2026 | 60-month new vehicle; 700 FICO, $33,000 loan and 10% down in the underlying national profile | 7.00% | National benchmark, not a guaranteed offer |
| Bankrate Monitor, September 23, 2026 | 48-month used vehicle; three-year-old car, 700 FICO, $20,000 loan and 20% down in the underlying profile | 7.50% | National benchmark, not a guaranteed offer |
| Navy Federal Credit Union, rates as of September 27, 2026 | New auto, 12–36 months | As low as 3.89% | Advertised floor; approval and eligibility conditions apply |
| Navy Federal Credit Union, rates as of September 27, 2026 | New auto, 37–60 months | As low as 4.29% | Advertised floor; approval and eligibility conditions apply |
| Interior Federal Credit Union, effective September 1, 2026 | New auto, up to 60 months | As low as 4.24% | Advertised floor; approval and eligibility conditions apply |
The Federal Reserve’s G.19 release, issued September 8, 2026, also provides official commercial-bank new-auto finance-rate series for 48-, 60- and 72-month terms. Those series are useful for broader market context, but a lender’s written quote is what determines your actual borrowing cost.
What counts as a “good” auto-loan APR?
A rate is good when it is low for your credit tier, vehicle, term and loan amount—not merely lower than a headline rate. Compare your firm preapproval with current benchmarks for the same term and vehicle type. A quote materially below the national profile may be competitive; a quote near or above it may still be reasonable if your credit, vehicle age or loan structure differs.

Credit tier is the largest personal variable
Navy Federal states: “Advertised ‘as low as’ annual percentage rates (APR) assume excellent borrower credit history.” The lender also says the actual APR can vary with credit history, loan type, model year, mileage, term and loan amount. Other lenders make similar risk adjustments, so an advertised floor should never be used as your expected rate without a preapproval.
New and used vehicles are priced differently
Used-car loans can carry higher APRs because older vehicles provide less collateral value and may have more uncertain condition or resale value. Compare a used-car quote with the used benchmark, not with a new-car promotion.

Advertised rates by term
Longer repayment periods generally come with higher APRs in the cited lender schedules. They lower the required monthly payment but usually increase total interest and keep you in debt longer.
| Term | Navy Federal new-auto APR (as low as) | Interior Federal new-auto APR (as low as) |
|---|---|---|
| 12–36 months | 3.89% | 4.24% (up to 60 months schedule) |
| 37–60 months | 4.29% | 4.24% (up to 60 months schedule) |
| 61–72 months | 4.59% | 4.34% |
| 73–84 months | 5.99% | 4.74% |
| 85–96 months | 7.39% | Not stated |
Navy Federal’s supplied rate summary lists used-auto floors of 4.79%, 5.29%, 5.39% and 6.98% across four term bands; the exact band associated with each figure should be confirmed on the lender’s current rate sheet or in your application. Interior Federal lists used-auto APRs of 4.34% for up to 60 months, 4.44% for 61–72 months and 4.84% for 73–84 months.

Why a lower payment can cost more
For any offer, calculate total of payments plus fees, then subtract the amount financed to estimate interest. A 72- or 84-month loan can make a vehicle fit your monthly budget while adding years of interest and increasing the risk that you owe more than the car is worth. Choose the shortest term whose payment remains comfortable after insurance, fuel, maintenance and other debts.
Where to look for the best offer
Credit unions
Credit unions often publish competitive floors, as the Navy Federal and Interior Federal schedules illustrate. Membership, geographic or employment eligibility, minimum loan amounts, vehicle-age rules and mileage limits can apply. Confirm that you qualify before relying on a posted rate.

Banks
Banks provide broad access and may offer relationship discounts, but their pricing can differ by term and credit tier. Ask for an itemized APR and fee disclosure rather than comparing monthly payments alone.
Manufacturer captive finance companies
Automaker-affiliated finance companies sometimes subsidize rates on selected new models or promotional terms. Check whether a promotional APR requires choosing a different rebate, a specific model, or a short repayment period.

After purchase, refinancing can reduce APR if your credit improves or market rates fall. Compare any new origination or title fees and verify that the new term does not erase interest savings by extending repayment.

- Standardize the scenario. Give every lender the same new-or-used status, vehicle price, down payment, trade-in credit, amount financed and repayment term.
- Obtain multiple quotes. Seek a credit-union quote, a bank quote and any manufacturer offer for which you qualify. Ask whether each result is a firm preapproval or only an advertised floor.
- Compare APR first. APR incorporates interest and certain required finance charges, making it more useful than the note rate or monthly payment alone.
- Compute total interest. Multiply the scheduled payment by the number of payments, add required fees and subtract the amount financed. Use the lender’s amortization schedule when available.
- Check restrictions. Review origination fees, prepayment terms, required membership, minimum and maximum loan amounts, vehicle-age limits, mileage limits and any restrictions on private-party purchases.
- Read the final disclosure. Confirm the approved APR, term, amount financed, payment, late-payment provisions and whether optional products were added.
Questions that can change your rate
- Is the vehicle new, used, certified pre-owned or purchased from a private seller?
- What are the model year and mileage?
- How much are you borrowing after down payment and trade-in?
- Which credit tier and debt-to-income profile does the lender use?
- Does the lender require membership or a particular geographic, employer or organizational relationship?
- Are there origination, documentation, title or prepayment charges?
- Does the quoted rate apply for the entire term, or only for a promotional period?
A practical decision rule
Start with a preapproval for the shortest affordable term, then use it to negotiate with the dealer or another lender. Accept a longer term only when the payment difference is necessary for your budget and the total-interest cost is clear. If two offers have similar APRs, prefer the one with fewer fees, flexible prepayment rules and vehicle requirements you can meet.
