August Forecast Puts New-Vehicle Payments at $812 as Negative Equity Reaches 28.8%

Why it matters

A declining year-over-year sales comparison does not necessarily mean current demand has weakened by the same amount. August 2025 included purchase acceleration before federal EV credits expired on September 30 and counted the Labor Day selling weekend inside the month; Labor Day falls in September's reporting period this year. J.D. Power says those calendar and policy effects make the annual comparison unusually noisy.

Stores should therefore separate traffic and close-rate performance from the national volume headline. A dealership can face healthy demand and still lose transactions when payment, equity and term limits fail to align. Daily reporting should distinguish credit availability, payment objections, negative-equity exposure, lender callbacks and inventory mismatch instead of treating every unsold customer as the same problem.

Lower rates are not offsetting price and equity pressure

The forecast places the average new-vehicle transaction price at $45,563, up 2.0% from a year earlier. Average new-loan interest is expected to ease six basis points to 6.55%, the lowest August reading since 2022, but the average payment still rises because financed balances and trade positions remain difficult.

Long terms are carrying more of the burden: 13.9% of financed transactions are projected at 84 months or longer, up 2.1 percentage points year over year. Subprime penetration is projected at 10.8%, up two points. F&I teams should present term, amount financed, total cost and equity consequences clearly rather than allowing an affordable monthly number to obscure the structure supporting it.

Hybrid demand is growing into a supply constraint

Hybrid vehicles are forecast to represent 18.2% of August retail sales, up 4.8 percentage points and 35.5% in volume from a year earlier. J.D. Power also says availability is unusually tight on some high-volume hybrid models. Electric-vehicle share is projected at 7.2%, down after the federal purchase-credit expiration changed the comparison with last year's pull-ahead.

That split calls for market-level inventory decisions. Dealers should compare hybrid lead volume, days to sale, gross, deposits and lost-sale reasons against actual incoming supply, while evaluating EV demand separately by model and local economics. A national mix change does not prove that every hybrid deserves more allocation or that every EV requires heavier discounting.

What dealerships should do now

Sales and F&I leaders can add negative equity, requested payment, approved term and final disposition to the daily sales meeting. Used-vehicle teams should identify trades purchased during peak-price years early enough to set realistic expectations before a customer becomes committed to an unsupported payment target.

Management should also compare the forecast with completed August results once the month closes. Until then, the figures are best used as a national benchmark for questions—not as a substitute for the store's own leads, approvals, trade positions, inventory age and delivered gross.
