June was the month the math stopped working in the buyer’s favor. Three forces that had been pulling in different directions — prices, loan rates, and incomes — shifted alignment, and affordability slipped.
The Cox Automotive/Moody’s Analytics Vehicle Affordability Index for June shows the average new-vehicle price rose 0.4% month over month to $49,758, according to Kelley Blue Book estimates. The estimated average auto loan rate climbed to 9.58%, up from 9.53% in May. Income growth, which had been doing meaningful work on the affordability side of the ledger, continued at 0.3% month over month — solid, but not enough to offset the pressure from the other two variables. Incentives, which had been a modest counterweight, also pulled back slightly in June.
The result: the typical monthly payment increased 0.7% to $763. The number of median weeks of income needed to purchase the average new vehicle edged up to 35.3 weeks from an upwardly revised 35.2 weeks in May.
One month of deterioration does not rewrite the larger story. The average monthly payment peaked at $795 in December 2022 and has stayed remarkably contained since, averaging $758 through the first half of 2026. And the year-over-year picture is still better than it was in June 2025, even though prices are 0.6% higher than a year ago. The reason: loan rates are lower than they were twelve months back, and incomes have grown 4.1% year over year — a gap wide enough to offset the higher sticker. Incentives in June were also 1.5% above their year-ago level.
The headline comparison that captures the trend most cleanly is the weeks-of-income figure. The estimated weeks of median income needed to buy the average new vehicle in June was down 3.4% from a year earlier. That number suggests, as Cox Automotive frames it, that broad economic conditions are doing more to constrain buyers than vehicle prices themselves.
Buyers are adapting anyway. New-vehicle transaction prices have held below $50,000 for six consecutive months, partly because the mix has shifted. Subcompact SUVs, with an average transaction price of $31,113 in June, saw sales rise more than 23% on an annual basis. Shoppers are moving down-market to manage monthly obligations, which compresses the industry’s reported average price even as underlying pricing on individual segments grows. That dynamic obscures nearly 2% in underlying price growth beneath the headline ATP figure. And at the other end of the financing timeline, nearly one in four new-vehicle buyers stretched their loan to 84 months or longer in the second quarter, another sign that buyers are engineering their monthly payment rather than shopping by total cost.
The 84-month term and the subcompact SUV shift are two sides of the same pressure. One reduces the payment by extending the timeline; the other reduces the payment by buying less vehicle. Neither is a sign of comfortable affordability: both are coping mechanisms.
The next Cox Automotive/Moody’s Analytics Vehicle Affordability Index update is scheduled for August 17. If rates hold near current levels and the mix shift toward smaller vehicles continues, the weekly-income figure will be the number to watch. It has been trending in the right direction for a year. June was a reminder that the trend is not guaranteed.
